FAQs
How does laser cutting work ?
Laser cutting works by having a high-powered, highly-focused laser beam run through a material, leaving a clean cut with a smooth finish. This beam can be either pulsed, meaning the cut is delivered in pulses, or continuous wave, meaning the beam is kept focused on the material until the cut is delivered.
Cutting with lasers starts by piercing the material with a hole, and then continues the cut from there. The beam intensity, length and heat output can be controlled, allowing the cut to be delivered in different ways and in different times.
The process is, in some ways, similar to drilling and engraving. Drilling involves the creation of popped ‘thru-holes’ in materials, but occasionally these holes are created as dents rather than thru-holes. These dents, acting like engravings, are also considered ‘cuts’ in a material.
The diagram above is an example of how laser cutting works, although there are different processes which work in different ways
What materials can be cut ?
Thanks to the control of beam intensity, length and heat output as described above, lasers are great at cutting many materials. Listed below are just some of the materials that cut well with:

These include the automotive industry, the aerospace industry, the semiconductor industry, the electronics industry and the medical sector.
What are the advantages of cutting with a laser ?
There are a huge number of advantages to its users:
- Control – Laser cutting allows for great control over beam intensity, length and heat output
- Low power – Laser cutting uses an extremely low level of power consumption, typically around 10Kw as compared to 50Kw used by other processes
- Material diversity – Laser cutting can work with a huge range of materials
- Non-contact – Laser cutting is a non-contact process, meaning that the laser beam itself never actually touches the material it works with. This reduces heat damage to the surrounding area, which increases productivity by decreasing downtime and repair costs
- Low operating costs – Laser cutting machines have very low maintenance costs and inexpensive parts for replacement
- similar environments
- Precision – Laser cutting delivers precise cuts with smooth finishes
- Multiple applications – Laser cutting can switch quickly between multiple applications and setups, reducing time wastage and the need for multiple machines
- Safety – This is a much safer method than traditional processes, the laser beam is in a closed tight sealed box
- Speed – Laser cutting is much faster than traditional methods and therefore offers faster turnaround times, which can be all-important in manufacturing and
Why is laser cutting better than other conventional processes ?
It offers unique benefits over other more conventional forms of cutting. It has a lower power consumption, typically around 10Kw compared to 50Kw of other forms, and it operates at a much quicker and more precise rate. Also, it is safer as the laser beam is enclosed within a tight light box, whereas with other conventional methods typically a free running blade is doing the cutting.
How accurate is cutting with lasers ?
One of the biggest benefits of the cutting process is the accuracy and precision that it provides to its users. With a focused, narrow beam, it can provide an ultimate level of accuracy.
Slits with widths as small as 0.1mm are achievable with laser cutting.
What are the capabilities of laser cutting ?
The process is capable of performing a huge number of tasks. Thanks to the accuracy and speed that it provides, you will see it being used to delivery cuts in materials, make holes, create complicated shapes, and even to perform surgery on human tissue.
Will cutting damage my material ?
No, and this is one of the greatest advantages of all. As it is a non-contact process and uses a beam that is highly precise on the area it is being focused upon, heat damage is minimal to the surrounding area of the material.
Are there different types of laser cutting ?
Yes, there are several different types and techniques of laser cutting. The three main types are C02, CRYSTAL and FIBER.
What is a fiber laser ?
In short, a fiber laser is a laser which uses fiber, which has been doped in rare-earth elements (erbium, neodymium, ytterbium) etc. as its medium. This is in contrast to the two main other types of laser on the market; a crystal laser and a gas laser.
Why should I choose a fiber laser ?
This is one of the most frequently asked questions that we get here at Maity Laser Tech, as prospective customers want to know what benefits a fiber laser will offer them over the other types on the market.
A gas laser is the most commonly used laser, but this is because it is the oldest type. A fiber laser, on the other hand, is the newest type of laser to grace the manufacturing world. The reason that we only manufacture and sell fiber lasers at SPI Lasers is because for us there are far more benefits than any other type of laser.
They offer a higher level of efficiency, speed and power, are maintenance free (thanks to fit and forget technology) and costs are dramatically lower than the alternatives. They can also cut reflective materials, often used in many industries, without any damaging back reflections (using our patented back reflection technology). Finally, they offer the user complete control in terms of beam length, duration, intensity and heat output.
Which industries can fiber lasers be used in ?

What kind of materials can you laser cut ?
Maitry laser Tech specializes in cutting mild steels up to 0.750" and stainless steels up to 0.625". We also cut aluminum and copper based metals for our OEM customers. Our lasers are capable of cutting many other materials including acrylics, brass, galvanized steel, Inconel, plastics, tool steel, and wood.
Why should I consider laser cutting for my custom parts ?
Lasers have many advantages over other conventional metal cutting and metal fabricating processes. Laser cutting can produce very complex parts while cutting materials from 0.005" to 0.750" thick. Lasers can cut the hardest materials and leave burr-free edges. The laser cutting process is extremely repeatable and produces parts with virtually no distortion. Laser cutting is well suited for rapid prototyping and provides a cost effective solution for short run production, making it a good alternative to metal stamping.
The narrow laser cut (kerf) width created by material removal, provides for the efficient layout of parts (and more parts per sheet), with less material scrap waste than most other cutting methods.
In most cases, laser cutting offers major benefits over short run stamping, plasma cutting, wire EDM, water jet cutting, and NC milling. Lasers are capable of cutting steel, stainless steel, alloys, copper, aluminium, and brass. They are capable of cutting non-metallic materials like plastics, ceramics, rubber, quartz, wood and even some composite structures. Overall, laser cutting out performs plasma, water jet, NC milling, and conventional saws in nearly every cutting process. However, for some materials, thickness requirements, or tolerances, other metal cutting processes may be more efficient.
What's the typical processing time for a laser-cutting job ?
The processing time is really a function of the job's complexity, so it depends. Maitry laser Techcan turn around laser cut parts in as little as a few hours, but some jobs might take a week. We also fill many rush jobs and will produce and ship partial orders to ensure our customers' production is uninterrupted.
Don’t most laser cutting processes leave material on the bottom edge of the part?
It depends how you operate the laser. At Maitry laser TechLaser, we regulate the laser power, our feed rates, and the assist gases we use in our laser cutting production to minimize and eliminate machining damage created by dross on the bottom side of the material during the laser cutting process.
What kind of drawing files can you accept for my laser-cutting project ?
We do our fastest work when we receive emailed .DXF files. Preferably, files are submitted in or AutoCAD 14.dxf or newer .DXF files.
How should I provide files containing text ?
Provide text-containing files in Adobe Illustrator (AI) or Corel Draw format.
What is the maximum sheet size Maitry laser Techcan handle ?
Maitry laser Techcan handle sheets up to 60" x 120". Our 4020 LXP laser utilizes a pallet changing system that allows us to change sheets in 30 seconds, increasing our production capacity and decreasing processing times for your job.
How can I keep the costs down on my laser cut parts ?
You can help yourself cut costs by providing clean legible prints, which helps to eliminate needless questions. If you e-mail a clean .DXF file to Tesko Laser with no overlapping or incomplete lines, you are providing the most efficient method of providing a print for quoting or processing. Since the potential for blowout occurs primarily at sharp (90-degree) corners, using radii (fillets) where possible is a great help in reducing.
What is CNC machining?
CNC (Consumer Numerical Control) milling and machining is a process in which high tech software creates parts or components for manufacturing. These parts tend to be more accurate and of higher quality than if they were produced using other manufacturing methods. As a result, CNC machined parts are used in industries which rely on absolute accuracy, including aerospace and firearm production. The CNC machines used by Jones Tools & Manufacturing are capable of delivering smaller, delicate components.
CNC is an extremely difficult process beginning with the initial design phase. Computer code is translated into electrical signals for the machine’s controls, telling it where and how to cut metal to produce the desired components. Those who operate the machines need proper training as well. Even with the computer doing the advanced calculations, a human touch is needed to ensure the final produce is produced correctly. If there is an error in the code, Jones Tool technicians are able to make the necessary corrections.
Which industries benefit from CNC machining?
Many industries benefit from CNC machining, though they are far more necessary in some fields than others. Different CNC machines are capable of different levels of detail during production. For the aerospace industry, this is essential to their highly specified design plans. There is no room for error when launching a rocket or flying a plan, and CNC machined components from Jones Tools & Manufacturing are made to be as precise as possible.
What types of CNC machining are there?
There are several different types of CNC machining. These include CNC turning, CNC milling, and CNC lathes. Each has different benefits for creating component parts. If you are not sure which method would be best for your parts, just ask our experienced technicians and we will happily assist you.
What is CNC turning?
CNC turning involves rapidly rotating a piece of machinery during production. This allows work to be done equally on all sides of the component. Without CNC turning capabilities, pieces would have to be manually switched over to be finished.
What is CNC milling?
CNC milling creates components by cutting down material along the axis of the piece. Mills are very similar to drills, though they can work along multiple axes instead of just one. The CNC milling machines used by Jones Tools are able to work along 5-axex, giving you greater control over your component. CNC milling is able to replace hand-engraving on parts.
What is CNC lathe work?
CNC lathe work is usually combined with turning in order to produce rounded parts like screws. Lathe work is beneficial to many industries by creating equal, uniform surface area on all sides for spherical and multidimensional components. Our CNC lathes are replacing older lathes since they are more accurate and easier to operate. Feel free to contact the team of Jones Tools & Manufacturing for help with your next CNC lathe project.
What are OEM engineered component parts?
OEM stands for Original Equipment Manufacturer, referring to a company which produces components for use by another company. Jones tools & Manufacturing is capable for creating OEM engineered component parts for all sorts of industries. By creating parts for you, your company is freed up from machining work. This is especially common in the aerospace and auto industries, as they only need Jones Tools to produce a variety of parts rather than trying to machine them on their own. If your business requires specific parts, contact our technicians today to learn about our OEM capabilities.

In some cases +/- .0002 is possible with the high-quality equipment we have in our machine shop. To find out exactly what you need, contact our offices today with your requirements.
What is CNC Milling?
CNC Milling is the removal of metal with a rotary cutter or other rotating cutting tool. Our 3-axis milling feature a 30,000 RPM spindle which allows us to cut at high speed with smaller cutters, and features an automatic tool changer which decreases total time to cut a part.
How large of a part or panel can be CNC machined?
The maximum size sheet metal parts we are able to mill in a single setup is 4' x 8'. The maximum size bar stock that we are able to mill in a single setup is 26" x 16" x 12".
What is the smallest part or panel that can be CNC machined?
The minimum sheet metal part that can be vacuum-chucked without clamps is 5" x 5". Vices can be used for smaller parts. Please email [email protected] for more details.
What materials can be CNC machined?
CNC milling is most commonly performed on aluminium and copper. Steel and stainless steel may also be milled, but cycles are longer due to the inherent cutting characteristics of these metals.
What kind of work holding do you offer for CNC Machining?
Protocase offers a number of different ways to achieve proper workholding for your CNC machining needs, including vacuum chuck, vices, clamps and custom jigs. Visit our CNC Machining page for more information, or contact us to discuss your project.
Can you lathe parts?
Yes, we offer CNC Turning (Lathe), as well as CNC Machining with 5-Axis, 3-Axis and CNC Routers. View our CNC machining page to learn more about what we offer.
What is the tolerance of your CNC machining?
We specify a standard dimensional tolerance of +-0.005" for CNC machined parts. However, it is possible to achieve a tighter tolerances on our routers, lathes, 3-axis mills and 5-axis mills. If you require a tighter tolerance, please contact us, as tighter tolerances may increase the cost of your project and have to be clearly defined upon ordering. Learn more about our CNC machining tolerances here.
Can I use self-clinching fasteners in my CNC machined design?
Yes. Machined parts are generally used with concealed head Maitry laser Tech brand self-clinching fasteners. Inserting these fasteners into blind holes has the extra benefit of a smooth finish on the opposite sides of sheet metal after the fastener is installed. These Maitry laser Tech brand self-clinching fasteners can be used in sheet metal as thin as 0.075". View our CNC Milling page for a full list of stocked self-clinching fasteners for blind milled holes.
What kind of a finish does CNC machining leave?
Due to the spinning motion produced by the CNC milling machine's cutter, the surface finish of CNC machined parts will have visible toolmarks. If you require a smooth, unblemished finish to your part, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powdercoat.
Can CNC machined parts be powdercoated?
Yes. All of our stock powdercoat colours are available for powdercoating CNC machined parts as well (non-stock powdercoat colours are available with additional cost and lead time). Powdercoat paints with texture will cover toolmarks with no additional finishing operation. Non-textured paints (Smooth Polyester, Smooth Epoxy and Smooth Polyester-Epoxy Blend Hybrid) will not cover toolmarks, therefore an additional finishing operation such as grained finish will need to be performed before powdercoat painting.
Why was my CNC order quoted thicker than I intended?
The material used to CNC machine your design will always have a standard thickness tolerance, so it is part of our standard procedure to quote your design with some extra thickness. Visit our Fabrication Tolerances resource to learn more.
What types of welding do you offer?
Our welding capabilities include spot welding (a great option for permanent assembly) and seam welding using Cold Metal Transfer (CMT).
What is seam welding?
In seam welding, the two pieces are clamped securely and welded, and then any excess metal is removed by grinding. The end result is a continuously joined seam, which is useful for weatherproofing, reducing EMI leakage, and for achieving a seamless look and feel when desired. Seam welding uses Cold Metal Transfer (CMT), which generates only one-tenth of the heat of MIG welding, so warping and meltback are all but eliminated. Learn more about seam welding.
What is spot welding?
Spot welding is a fast and efficient method for permanently joining two pieces of sheet metal in one or more spots. Available on cold rolled steel, galvanneal and stainless steel, spot welding is often used as an alternative to threaded fasteners, as there is little trace of the joint. A minimum flange overlap of 0.5" is required for spot welding. When including spot welding on your design, please specify if you'd like the excess metal on the spot welding to be grinded down.
What materials can be welded?
We can weld Cold Rolled Steel, Galvanneal, Stainless Steel, Aluminium and Copper. (Note: copper is usually brazed).
What Is Metal Spinning?
Metal Spinning is the process of turning (spinning) a flat piece of metal on a lathe around a pattern allowing the metal to form to a desired shape.
When Is Metal Spinning used?
Metal Spinning is used when there is a need for a three dimensional shape (some examples include hemispheres, cones or bells) that is formed from a single piece of material. The benefits include greater structural rigidity.
What is CNC Machining?
CNC machining is a precise metal fabrication process. CNC stands for "Computer Numerical Control". This process uses computers for exact control of the position and velocity of the cutting element that is used to "machine" (i.e. make holes) in the work piece.
When is CNC Machining Used?
CNC Machining is a process used only when the highest level of precision is required. Used primarily for complex three dimensional shapes.
What is Precision Metal Fabrication?
Precision metal fabrication is a broad topic that covers many different areas; it is essentially the strict manipulation of metals based on exact specifications and tolerances. Precision metal fabrication involves, but is not limited to, metal spinning, CNC machining, welding, rolling, punching, etc.

Yes, with some sheet metal materials. All grades of aluminium and stainless steel can be sourced with a protective plastic peel able film on either one side or both sides of the sheet, known as PC1 or PC2. These plastic films on the sheet metal do help to reduce the chances of damage in handing in a manufacturing work shop environment. Unfortunately sheet metal work manufactured from mild steel and galvanized steels do not have this option available.
What are the benefits of steel?
- Cost – Steel has a high strength to weight ratio which causes reduced foundation costs. Faster construction saves on labour costs. Plus, long-term costs are reduced because steel structures don’t require much inspection and maintenance.
- Time – Apart from faster construction, prefabrication gives you more control over the project’s time flow. This allows for more efficient project management.
- Designversatility – Steel can be easily molded into any form. This gives the building’s architects incredible scope for creativity in producing innovative designs. The strength of structural steel means that it’s possible to build long spans without support columns.
- Adaptability – Steel framing can be easily extended horizontally or vertically. Support beams can be strengthened without reducing floor space. This makes extending or converting the building much easier than concrete structures.
- Healthandsafety – Steel is fire resistant and mold resistant.
- Environmentalbenefits – 90% of all structural steel is recycled making it one of the most environmentally friendly building material.
Do you do on-site welding?
Yes, we are fully set up for on-site welding as part of our installation process. We are set up for MIG, TIG and stick welding of steel, stainless and aluminium.
What is welding?
Welders play an extremely important part in fabrication shops. Welding is the method of joining two pieces of metal. This is done by applying extreme heat to soften the material and then apply pressure against the two items to unite them together in a melded state.
The welder must first inspect the engineered blueprint. Then, the welder will use a gas torch to fuse the joints of the sheet material. This is a complex process and it demands the undivided attention of the welder. If an unskilled person were working on this, it could result in the metal warping due to the high degree of heat.
Do you perform food-grade welding?
Yes, we perform food-grade fabrication that includes welding and polishing. We typically work in food-processing plants building spouts and hoppers. We work on these items here at our plant and on the job sites.
What sheet metal materials can you spot weld?
We can spot weld mild steel, galvanized steel and stainless steel.
What precautions to take with structural steel projects?
Precautions to taken:
- Corrosion – Structures that are exposed to harsh climatic conditions, like marine projects, require corrosion resistant alloys. However, other structures may also be vulnerable to corrosion. You should check whether the structure needs to be treated against corrosion with paint or other products.
- FireResistant – Steel doesn’t easily catch on fire, making it a safe choice. However other materials within the building may result in fires. Very high temperatures caused by fires can weaken steel, causing it to soften and buckle. For this reason it’s advisable to insulate steel used in the structure against heat damage.
What does metal fabrication entail?
Whenever you cut, shape, or join metals together, you are participating in the fabrication process. For instance, some of the most common procedures include welding, drilling, stamping, punching, milling, and forging, each of which uses a different type of machine to transform metals into a particular shape.
What is the difference between milling & drilling?
Metal fabrication Milling and drilling are very similar. Each uses a rotary tool to create holes in the metal. Drilling uses one or more bits to create circular holes of any depth, and the cutting direction moves straight down the tool's long axis. Milling, on the other hand, creates non-circular holes with a multi-headed tool that typically approaches the part from any number of directions.
What is welding?
Welding uses heat—often created by an electrical arc between the tool and the base metal—or sometimes pressure or friction, to turn two pieces of metal molten at the joint. They will then flow together and bond chemically during cooling.
What is a welding shield gas?
Remnants of oxygen from the atmosphere can cause the metal in a welded joint to corrode/rust. To prevent this, a shield gas like nitrogen or helium is blown onto the join point during welding to shield the metal from oxygen contamination.
