Here’s just a few of the questions Larry get’s asked regularly. We decided to post his answers here just in case you may have the same questions.
At Ontario laser cutting Inc. we have 5 lasers and are currently looking at adding more, this is not because we are so busy but because each laser has its own unique way of cutting parts.
Every laser model has a purpose that fits a specific type of customer. With this in mind we add options and features that will enhance the laser and therefore creates additional cost. An example of this would be a C02 laser versus Fibre Optic laser, 4000 watt lasers versus 2500 watt lasers or 6 axis laser versus 2 axis laser.
Our prices are based on time and material. We calculate the material required to make the part as well as the amount of time it will take to complete the part. We have a small allowance for price fluctuation as steel prices change weekly and calculate time as per the thickness and type of the material that is being cut. We have a complete data base of all materials with speeds and costs.
No, it would require a very powerful laser and the the glass would explode during its cooling cycle.
Laser cutting produces part shapes by cutting sheet material using an intense laser beam. This cutting method uses a beam of high-density light energy focused through a tiny hole in a nozzle. When this beam strikes the surface of the work piece, the material of the work piece is vaporized.
The advantages of this process is it offers low cost for prototype and short runs since no physical tooling is needed. Heat distortion is minimal and typically limited to about 10% of material thickness. Cut parts generally remain flat. Lasers leave minimal burrs.
Yes we do this often. This is mostly used for forming and also when a customer has built a prototype and now wants to start production. We usually try to redesign the part to make it simpler and more cost effective.
A PDF file is the best for quoting, they e-mail easy and are confidential. Once the order has been placed we usually prefer a Autocad type file.
Ontario Laser Cutting has its own fleet of delivery vehicles, we do personal deliveries throughout southwestern Ontario. Any orders outside of Ontario are done through shipping companies.
We stock over half a million dollars in inventory, we carry almost every type of material that can be used for manufacturing, some of the most rarest materials can be found here.
Our standard turn around is 4 days from the time of order, this largely depends on the size of the order and the material that is required to complete the order. We have 5 lasers and operate on multiple shifts, this gives us the ability to produce very large volumes of orders quickly.
We try our best to have your quote within 2 hours, this would also depend on how fast our supplies respond to our request for steel pricing and the uniqueness of the material that is being requested.
We purchase material from hundreds of suppliers and this gives us the ability to find almost any type of product. We also have over 600 customers in Ontario alone, if our supplies can’t find material there is a very good chance that one of our customers can find it. Networking is one of our specialties.
Yes we can, it does require using a special gas to keep the material from fracturing.
Some of our customers prefer to supply there own material, its not a problem for us to cut but lasers are very sensitive to rust and warped material, the material must be flat and free of rust or paint. I would also like to point out that we purchase high volumes of material, there is a very good chance that we can supply the material much cheaper than what a customer can purchase the material.
I would recommend having the material shipped directly from the steel company to our facility. We see approx 10 steel suppliers arrive at our shop per day, I should be now problem for you to have it shipped direct, if that is not an option than call us, we may have one of our vehicles driving by or have it shipped by a local courier.
We have the ability to cut a wide range of material thicknesses, In steel we can cut from 1.000″ thick to .001″ shim stock, Aluminum we can cut as thick .500″ and .750″ in Stainless Steel.
Our largest machine can cut 60″ wide by 120″ Long.
The laser cutting process does produce a slight taper, its more of an hour glass shape than it is a taper, it is not visable to the human eye and it also helps with reducing sharp edges.
Today’s lasers can hold +/-.001″ tolerance, the problem is during shipping there can be temperature changes and the parts can expand or contract making it very difficult to hold that tolerance. When we are cutting 3D objects such as structural tubing or pipe the material will twist and expand during the tensional changes that are taking place within the material. Our recommendation is +/- .015″ and this is usually exceptable.
Having top notch employees requires years of training as well as dedication and passion. Our average employee must learn Autocad, Solid works, Corel, Striker, Ncell, Mazatrol, FGCam, CPlus, Inventor, as well as many more programs, they must be proficient in Gcode editing as well as understanding all the various materials and how they react to laser cutting. We have licensed Millwrights on staff to make sure our equipment keeps running. These are some of the standards that we hold and most of our staff go way beyond these talents. Yes they are highly trained and excel in what they do.
I believe the new 6000 watt lasers can cut .750″ Aluminum, this material is not fun to cut as it is very sticky and reflects badly, water jet is a very useful way to cut thick Aluminum, the material is soft and waterjet machines can move quickly to cut this type of alloy.
Yes, this is a quenched and tempered low carbon material, this material can be laser cut with out any issues, most suppliers store this material outside so sandblasting before laser cutting will be a must.
In Ontario, “burr” is when you step outside on that cold February morning. In the laser cutting world “Burr” looks like small icicles hanging down from the edge of your laser cut part. In order for a laser to make a nice clean cut there are approximately 10 conditions that apply, Power, Feed rate, Gas pressure, material, nozzle gap, ect, ect, if one or more of these conditions are not met than “Burr” or better known as “slag” or “Dross” will appear.
It is short form for no sharp edges, all corners and sharp edges must be rounded off.
If you are looking for blocks of Aluminum, it may be better to purchase a bar stock and have it sawed to the proper length.
“AR” material is easy to cut and lasers should have no problem with cutting them. We cut AR material on a weekly bases.
No, the gases that are produced from cutting are very toxic.
There are two techniques for cutting acrylic, clean edge or cut edge, we have the ability to cut both ways.
Any time that you cut materials such as steel, Aluminum, Stainless there is a discharge that is pushed down into the bed of the machine, it is the molten liquid produced by the cutting process, this discharge happens from laser cutting, plasma cutting as well as water jet cutting. The removed material is forced downward through either gas pressure or water pressure. In laser cutting this material is hot and sticky, it welds itself to the ribs of the machine and makes a big globby mess. The molten material sticks very well to steel but does not bond as well to brass and even bonds less with copper. Some companies use cooper “slats” or “Ribs” instead of steel to reduce the replacement intervals.
These products can be laser cut but you have to keep in mind that they are manufactured using chemicals such as glues and resins. Adding heat or gases to these chemicals makes then unstable and unpredictable. Use caution and good ventilation.
Some plastics can be cut but others are toxic, some shrink and make them uncontrollable and other melt, some plastics become highly corrosive and can destroy the lasers components. We try to avoid all plastics.
Waterjet is the best process for thick aluminum.
Custom gaskets are easy, trace out or hand sketch what you want, put some dimensions on it, fax/scan and e-mail to us and we will draw the part to scale, then we e-mail it back as a pdf, you cut it out with scissors make sure it is what you want, once you approve of the drawing then we would cut and ship it. Easy!
In today’s world this is very common, we sign confidentiality agreements with many of our customers, we also have controlled entry and do no allow any customers onto our shop floor, this is purposely to protect our customers products.
What makes your company different?
We try harder. We’re here for our customers as a partner in their manufacturing process. Personal service makes all the difference. Larry Stuyt – President and Owner
Would you buy a used laser cutting machine?
Normally, I always try and purchase new. In our type of industry, the machines that are for sale ‘used’ are usually beat up pretty bad. If I had a chance to purchase a new machine that was [repossessed] from the bank, then I would buy used, otherwise I always purchase new. Larry Stuyt – President and Owner
Do you do fabrication?
No. We specialize in laser cutting. It’s our focus. It’s what we are good at. We are a partner to our customers offering a specific specialization. We do not take over the entire manufacturing process. Larry Stuyt – President and Owner
