CNC Machining

CNC Machining

CNC machining finishes a part to the final blueprint dimensions and tolerances for use or final assembly. With the investment casting process, after a part has been cast it is considered “near net shape.” Some parts may require final machining in order to meet all the blueprint tolerances.

We also offer our valued customers other finishing processes including:

  • Precision O.D. Grinding
  • Blanchard Grinding
  • Honing
  • Brazing

At Barron Industries, we utilize over a dozen of the industry’s leading CNC machines, Makino, Mazak, Mori Seiki and more including:

  • Vertical Milling Centers with 4th axis capability
  • Horizontal Milling Centers with 5 axis capability
  • Turning Centers up to 20” diameter

Barron Industries has assembled a team of expert CNC programmers and machinists. When your machining blueprints are received at Barron Industries, an experienced CNC programmer carefully examines each drawing requirement including surface finish, profile, true position tolerances and datum scheme for incorporation into fixture design/build and tooling specifications. Ongoing inspections are performed as specified in the control plan developed uniquely for each part.

Many rapid prototypes are both cast and machined. Barron Industries has developed proprietary work holding methods and hardware that can dramatically reduce or even eliminate the need for expensive machining fixtures. Our goal is to reduce both turnaround time and tooling costs.

Machine Fixture Design and Programming

Machined Alloys

Barron Industries has the unique capability to pour both ferrous and non-ferrous alloys. We cast a wide variety of aluminum, stainless steel, carbon and alloy steel, tool steel, and other exotic alloys. Barron Industries is experienced in the challenging machining of alloys such as  17-4 ph stainless steel,  90/10 copper nickel and  S7 tool steel to name a few. At Barron Industries we have a passion for performance and we strive to make your parts right the first time… every time.

Frequently Asked CNC Machining Questions

What is the typical turnaround time for CNC machining?

Although timing varies with each project, typical turnaround is usually 2-3 weeks. Since most projects include precision investment casting, we can use the same math data to create the cutter path program for CNC machining while the parts are being cast. Ultimately, this saves time and expense for our clients.


What tolerances can you hold in CNC machining?

Tolerances in machining directly correlate to the quality of the CNC machines. Barron Industries owns over a dozen CNC horizontal and vertical milling and turning work stations, each equipped with an industry top-of-the-line Makino, Mazak or Mori seiki machine. In addition, our full complement of tools, two Blanchard grinders and experienced skilled tradesmen are prepared to complete any CNC machining job to your most exacting standards.

Dimensional Inspection

How do you test the final product for defects?

Quality control is of utmost importance to Barron Industries and our valued customers. We build quality into each and every casting. We also offer the following forms of product defect testing in-house with Level-III certified personnel: Dye Penetrant testing, Magnetic Particle testing, x-ray inspection, tensile and physical properties, chemical and structural analysis. All testing results in a formal printed certification report.
