CNC Machining

CNC machining (Computer Numerical Control) uses computers to control machine tools including lathes, mills, routers and grinders.

There are many advantages to using CNC machining:

  • faster and more precise than manual machining
  • can be repeated in exactly the same manner
  • can produce complex shapes that would be almost impossible to achieve with manual machining

CNC Turning

CNC turning is a slightly different process compared to CNC machining. CNC turning relies upon computer-controlled machines, but creates a different end product. CNC turning is used to create parts with round or tubular shapes created from larger pieces of material.

PGI offers CNC lathe services which feature live tooling, allowing us to produce a complex part in fewer set ups and lowers your cost.


Manual Machining

PGI Steel also has a variety of manual machines, such as horizontal mills, planer mills and other small manual mills to support the machine shop.
