Plasma Cutting

Manufacturing Process

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

Manufacturing Process

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" (76.mm). 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.

Thickness Range Conventional Plasma 3/16" to 6.0 (4.8mm to 152.4mm)
Thickness Range High Definition 3/16" to 2.0 (4.8mm to 50.8mm)
Thickness Range Bevel Cut 3/16" to 3.0 (4.8mm to 76.2mm)
Bevel Range +/- 52 degrees

Plasma Beveling

Manufacturing Process

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.

Machincut Rings & Discs

Manufacturing Process

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

Manufacturing Process

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!

Product Development Process

Manufacturing Process

Analytical Formulations
Using the basic laws of physics and hydraulics, we use analytical formulas, wherever applicable, for a basic design formulation. This helps us design the product from First Principles. Our team refers to the latest published papers and standards during the process.

3D & 2D Modelling
After these calculations, we create options through Solid Models via 2D and 3D design packages which:

  • Resolve physical conflicts and fine-tunes the product
  • Help us drive the cost savings opportunities
  • Enable new developments to be finalised with speed and detailing
The models are then validated by our manufacturing experts.

Finite Element Modelling & Analysis

  • The developed design is validated virtually using the latest design and analysis methodology - Finite Element Analysis (FEA).
  • Through FEA, the solid model is first meshed, applied with a suitable material model and subjected to appropriate boundary conditions and solved using Solid-WORKS & ANSYS
  • Graphical output helps compare the Stresses/Strains with material parameters.
  • This virtual validation is iterated until a product is designed and validated that can be manufactured.

Manufacturing

  • Based on the virtual validation, manufacturing drawings are prepared.
  • Samples are made on our in-house CNC machines to the highest quality standards.

Final Testing

  • With our belief that "seeing is believing", the manufactured product is then taken to our centralised state-of-the-art laboratory
  • A range of performance tests are conducted to validate performance parameters
  • The newly designed product is then offered to our clients
