CNC Machining



Kovatch Castings operates a full-service, state-of-the-art, in-house CNC machine shop. Our machinists can provide turn-key precision parts ready for installation, eliminating the need for additional vendors.

Equipped with CNC machining centers with 4th axis rotary tables, manual mills and lathes, and state-of-the-art inspection equipment, we can handle short or long production runs.

Equipment (See detailed list)

Our VMC’s (vertical machining centers) are equipped with 4th axis index capabilities allowing us to machine multiple sides of a casting with one setup.

Our late model equipment is capable of holding close tolerances and high micro finishes.

The shop layout consists of work cells containing multiple VMC’s for efficient single piece manufacturing

Quality Control & Inspection

During the casting process, our in-house lab, headed by a Level III Technician, performs NDT, MPI/FPI, X-ray, metallurgical testing and process inspections assuring a good raw casting. When we machine those castings, the same disciplined system is used by the Machine Shop to assure that dimensional quality continues. With emphasis on dimensional inspection, the following software and equipment is utilized:

  • PC-DMIS Software - for the collection, evaluation, and management of manufacturing data.
  • CMM’s, equipped with PH10T Renishaw Probe Systems:

○ Brown & Sharp - Mistral 775
        Travel Distance: 26” x 28” x 18”

○ Brown & Sharp - ONE
        Travel Distance: 26” x 28” x 18”

○ Numerix #1518-10 (BENCH TOP)
        Travel Distance: 15” x 18” x 10”


Serving Commercial, Military, Medical and Aerospace customers, we have a wide-range of machining experience in areas such as:

  • Drilling
  • Engraving
  • Tapping
  • Grinding
  • Vertical boring
  • Flat grinding
  • Thread inserts
  • Bushing assemblies
  • HeliCoil assembly
  • Internal pocketing
  • Keyways
  • Smoothing radii
  • Slotting
  • Attaining finishes up to 32 micons or better

Tooling & Fixture Development

Working with the Kovatch Tooling Department, our engineers design and build all of the CNC machining fixtures in-house, giving us flexibility to change designs as needed.

Additionally, we are able to produce multi-station designs to help reduce the piece price machining costs.


Networked engineering development files are shared between Engineering and the Machine Shop via and the latest version of MasterCam Machining software. This assures manufacturing repeatability and assured accuracy. All of our CNC Machinists are MasterCam certified.

We can import files from the following design software packages:

  • Inventor
  • Solidworks
  • ProCast
