The CNC Plasma Process

The Torchmate CNC machine cuts out the entire 4' x 4' plate full of owl shapes automatically from 1/8" mild steel. The finished owls measure approximately 8" x 8", and sell wholesale to dealers for $20 each.  The entire run of 33 owls was completed in one hour, at a cost $1.75 each in steel and plasma torch consumables.  That comes to $602 profit for an hour's work.

Stepper Motors vs. Servo Motors vs. Intelligent Motors - The Facts

Depending on whose web site you visit, you will be offered a variety of reasons why their type of electronics and motors are better than the rest.  The purpose of this page is to give you the straight facts, without distorted torque figures or unrealistic cutting speed claims.

Designing the Torchmate

Purchasers of our Torchmate 2 gantry kits are supplied with a digital 3-D model of the completed machine.   They can rotate it, and zoom in to see the finest detail from any angle, helping to make the kit's completion easy and fun.  Full instructions are also provided.   Viewing the 3-D model requires the SolidWorks viewer, which can be downloaded free at: http://www.solidworks.com.

Torchmate Advantages

In the above photo, a 4 foot square table has been placed inside a 5' x 8' capacity Torchmate 2 machine.  The dramatic size difference illustrates the tremendous advantage of a full sized machine over a small 4' x 4' unit which requires you to constantly move and realign (index) your material.

The Inherent Accuracy of Plasma ARC

Plasma arc is a marvelous process, allowing you to cut non-ferrous metals as well as mild steel.   However it does have some limitations.  We believe that you should be aware of what is and what is not possible using plasma, regardless of whose CNC machine you purchase.   Plasma will produce good results for perhaps 95% of the applications out there, but you're not going to cut watch parts with it.

How Do We Compare

A pretty good indicator of the reliability of a company is how long it has been around!  The photo below shows a number of National magazines from 1980 - 1982 containing one to four page feature articles on our Torchmate cutting machines.  Our Torchmate pantograph flame cutting machine won the "Product of the Year" award in 1980 from Welding Design and Fabrication Magazine.

The Seven Deadly Sins in Selecting a CNC Cutting Machine

The most limiting factor of any CNC cutting machine is the size of the plate that can be cut without interruption.  Since most material comes in at least a 4' x 8' size, your cutting table should be at least that size.

Is Accuracy and Repeatability Important to You? It Should Be!

If you really want to know how accurate a CNC shape cutting machine is, test it with a laser. CNC plasma-arc cutting is great for most metal fabrication jobs.  It's fast, economical, and accurate enough for most metal cutting needs.

Early shape cutting machine patents

Mr. Bucknam, who had previous patents going back to 1916 designed this as a cutting machine for trimming the flanges on boilers.  It uses a pivoting column that supports a track extending outward from the column.  A carriage, mounted on the track, rolls in and out as a roller follows the profile of the flange.

Steps to fabricating frame and rails – approximately 16 hours

You will fabricate the frame out of 3" square x 1/4" wall tubing you purchase locally.  Full plans are included.

Plasma Cutter History

The plasma-arc process had its origin almost 50 years ago, during the height of World War II.  In an effort to improve the joining of aircraft materials, a method of welding was developed that used a protective barrier of inert gas around an electric arc to protect the weld from oxidation.

How a plasma cutter works

Plasma cutters work by sending an electric arc through a gas that is passing through a constricted opening.  The gas can be shop air, nitrogen, argon, oxygen. etc. This elevates the temperature of the gas to the point that it enters a 4th state of matter.  We all are familiar with the first three: i.e., solid, liquid, and gas.

Selecting a plasma cutter

So you want to purchase a plasma cutter!  It's kind of a bewildering prospect to select a piece of equipment that is new to you with so many manufacturers and models to choose from.

The Making of a Monster Torchmate CNC Plasma Cutting Machine

What does buying an industrial CNC plasma cutting system and riding the New York City subway have in common? The sheer size and complexity alone from a "newbie's" perspective could send anyone running in the opposite direction. However, if you are planning on walking the streets of NYC, it is going to take you a long time to get to where you are headed.
