Plasma Cutting

Our computer controlled plasma cutting equipment provides one of the most efficient and least costly cutting methods available.

Although it doesn’t provide the same concentricity, tolerance or smooth square edge as Machincut, our plasma cutters minimize the heat affected zone that is usually associated with a plasma cut edge, allowing for better tool life and higher speeds and feeds when you are doing additional machining in-house.

High Definition Plasma Cutting System

Mcneil Instruments Inc High-Definition Plasma Cutting System with Plasma Beveling Precision High-Definition Cutting Combined With State-of-the-Art Plasma Edge Beveling Unsurpassed Flexibility in Processed Stainless and Nickel Alloy Plate Parts

Once again, Mcneil Instruments Inc is on the forefront of the implementation of plate processing equipment for the production of Stainless Steel and Nickel Alloy Plate Parts. We’ve added a state-of-the-art High-Definition Plasma Cutter capable of cutting high definition up to 2.0″ (50.8mm). The machine is also equipped with a Plasma Edge Beveler that can bevel parts through 3.0″ ( Our high-definition cutting system combines Y-axis linear ways with pitch line rack and pinion drives to provide the industry’s smoothest cut edge and precise holes. Wider end trucks with a maximum guide roller spread further stabilize the X-axis motion for the ultimate cut edge performance.


The new bevel cutting head, combined with a sophisticated software package, provides the most precise plasma cut edges available in the market today. The system’s unique design keeps the critical components away from the cutting torch, minimizing the risk of damage to the torch by slag, heat, and unwanted contact.

The plasma beveler head is capable of accurate beveled parts on any angle from +52 degrees to -52 degrees. Torch height is automatically controlled to an accuracy of +/- .006″ (15mm), so part integrity is maintained throughout the cut. Corner loop size down to 0.394″ (10mm) can be achieved without requiring start/stop commands. The result is accurate parts with square corners and minimal scrap up to 3.0″ (76.2mm) thick.


Plasma Beveling

Plasma beveling enables us to cut your parts to size and bevel the edges in one step. This cuts your manufacturing costs by eliminating or reducing downstream processing.

Most shapes can be beveled, including rectangles, circles, and parts created in a CAD program. Beveling can be performed on plate up to 3.0″ (76.2mm) thick, plus or minus 52 degrees, knife edge or with a land.

Abrasive Waterjet Cutting

At Mcneil Instruments Inc we are committed to providing our customers the most efficient and cost-effective methods of cutting Stainless Steel and Nickel Alloy Plate and plate products. In addition to our already diverse capabilities of plate processing, we are now offering multiple abrasive waterjet cutting systems to address your cutting needs. Our two WMC Series machines feature four cutting heads, integrated abrasive removal and recycling systems, WindowsT-based PC machine control and programing, and 60,000 psi pumps.

Mcneil Instruments Inc abrasive waterjet cutting system can provide near-net shapes and intricate parts cut to the accuracy levels and close tolerances our customers require. Secondary finishing can now be minimized if not totally eliminated. Unlike other cutting processes,Mcneil Instruments Inc abrasive waterjet cutting system assures you of receiving consistent superior edge quality with no heat-effected zone. The lack of a heat-effected zone enables us to nest patterns more closely providing better material yields for you the customer.


Our four machines with seven cutting heads and custom-designed water tables allow us to cut sizes ranging from your smallest parts up to pattern sizes of 160″ (4064mm) x 240″ (6096mm) on our standard machines and 156″ (3962mm) x 288″ (7315mm) on our five-axis system. We can cut pieces up to 6.0″ (152.4mm) thick and weighing up to 20,000 pounds.


5-Axis Abrasive Waterjet Cutting

Mcneil Instruments Inc’s latest addition to our state-of-the-art plate processing capabilities is our new Jet Edge EDGE X-5 five-axis abrasive waterjet cutting system.

It is capable of processing your most challenging three dimensional cutting requirements. This machine enables us to offer you cost-effective contour bevel parts, chamfer holes, and weld bevels including K-Bevels.

Machincut Rings & Discs

Our “speciality of the house.” Machined finishes are available at virtually the same cost as plasma cutting. Our rings and discs are machined to a tolerance of +1/16″ – .000″ on the O.D. and +.000″ – 1/16″ on the I.D. to give you a smoother edge with better concentricity than a plasma cut edge. In addition, you have no heat affected zone, which increases your tool life. We can turn up to 124″ (3150mm) OD, and face the surface of one or both sides to any special thickness or RMS finish. All of this means a lower ultimate “cost in use” to you.

With our unparalleled in-house processing capabilities, nearly any machined configuration is readily available. We can provide bevels, grooves or fine surface and edge finishes that you need.


Bandsaw Cutting

Bandsaw cutting provides a better edge quality than plasma cutting, with no heat-affected zone on the edges. Ideal for rectangular plate and bars cut from plate from .250″ (6.3mm) thick to 6.0″ (152.4mm) thick; up to a maximum cut plate size of 124″ (3149.6mm) wide by 274″ (6959.6mm) long. Tolerances of +.125″ to -0″ on the width and length of the part can be achieved.
The Center was designed to process our largest full-size plates. As a result, we can provide a cut piece as large as 124″ wide and 274″ long. Additionally, the saws can cut narrow bars. This is especially useful for supplying bars cut from plate for non-standard bar sizes and types.

Mcneil Instruments Inc offers bandsaw cutting, abrasive water jet cutting, plasma cutting, and extensive machining capabilities up to 124″ (3150 mm) OD under one roof. When matched with our outstanding service and our 18 million pound inventory of Stainless Steel and Nickel Alloy Plate, Mcneil Instruments Inc’s Bandsaw Cutting Center provides the complete package for a cutting service operation!

Drilling (Tubesheet & Baffle), Tapping, Counterboring

Our proprietary research and development in drilling technology, combined with our state-of-the-art automatic indexing drilling equipment, result in a very low cost per drilled hole.

Standard bolt-hole patterns can be drilled and shipped in the same turnaround time as machined ring or disc blanks. We also can provide thread tapping and additional counterboring when required.



Need a special edge finished with close tolerances on rectangular plate? Mcneil Instruments Inc can do this on our special heavy-duty milling machines.

Need the same edge finishes on shapes and configurations? Mcneil Instruments Inc can do contour milling on our sophisticated three axis, double column, vertical machining center. Edge beveling is also available.


At Mcneil Instruments Inc, we’re highly experienced in polishing stainless and nickel alloy plate and can provide a standard #4 finish or a 5 RMS maximum when requested. This can be done on all shapes.



Commercial mill flatness tolerances for stainless steel plate and nickel alloy plate don’t meet the requirements of most customers today. At Mcneil Instruments Inc, we do much better. Nearly every plate product we ship is individually flattened prior to shipping –at no additional cost to you. When your flatness requirement is especially critical, we have capabilities of flattening stainless steel plate to within .0625″ (1.6mm), based on the thickness and size of the piece. Flattening tube sheet blanks is Mcneil Instruments Inc’s specialty.

Rolled & Welded Rings

Mcneil Instruments Inc’s rolling and welding processes economically give you the large diameter rings you need by eliminating the yield loss of standard plate rings.

We can cut stainless and nickel alloy bars and roll them into easy-way or hard-way rings, within full ASME compliance, including code welding and x-ray.
