What is CNC Machining?

CNC precisionComputer Numerically Controlled or precision CNC machining was initially developed over 50 years ago by a group of machine tool builders involving machine work that needed to be completed for the U.S. Air Force. From its early inception, precision CNC machining was designed to consistently replicate and reproduce parts requiring multiple complex machining steps, eliminating the part-to-part variations of the human machinist/operator. The successful result of a CNC precision machining and 4 axis machining process relies on experienced CNC machining specialists to program the CNC procedure properly, since the entire process, once started, is automated.

CNC Machining Advantages

CNC precisionCNC machining offers the following advantages:

  • Highly precise production parts- extremely small tolerance variations, with the resulting components being virtually the same in all aspects.
  • Low labor requirements and costs - one experienced precision machining specialist, using a CNC machine, can perform the jobs of several people. Fewer errors on the finished component mean lower cost to produce parts.
  • Increased productivity - once the initial setup is done, precision CNC machining can literally continue 24 hours a day (limited only by cutter wear if applicable and the on-hand inventory of the raw material being used).
  • Safer production - the precision machining specialist monitors the process, but is not involved in performing the machining steps of the process, leading to a safer manufacturing environment. The precision CNC operator oversees the automated process and can stop the CNC machining, if a correction is required.

Along with 4 axis machining, precision CNC machining and custom metal fabrications services, additional in-house capabilities at the Pen CNC machine shop in Southern California include but not limited to:

  • Plumbing
  • Hydraulic assembly
  • Electrical wiring
  • Glass-beading
  • Painting
  • Delivery to the customer's site
