Large Scale Industrial Surface Grinding

Custom Engineering offers multiple styles of large scale surface grinding for a variety of materials. We use Blanchard grinding to provide an excellent quality finish that will meet your exact specifications. Our skilled operators are able to provide precision flatness and parallelism to dimensions of .001” and thickness to +/- .0005”.

Blanchard/Rotary Grinding:

  • 72” rotary table
  • 84” swing
  • 22” height

With over 50 years of experience in precision surface grinding, the experts at Custom Engineering use Supertec horizontal surface grinder to deliver extreme precision flatness and parallelism with a smooth finish to large surface area projects accommodating parts as large as 80” wide, up to 118” long, with height up to 18”.

Precision Surface Grinding:

  • 40” width
  • 120” length
  • 18” height

CNC Turning Centers with Live Tooling

Custom utilizes Computerized Numerical Controlled (CNC) turning centers, which allow for precision facing, turning, boring, threading, drilling, grooving, trepanning, and milling operations. Our equipment offers a 4 axis turning center, allowing all 2 axis functions normally associated with turning centers to be executed with two turrets simultaneously, as well as turning centers equipped for large diameter work up to 40”. Custom offers speed and precision with Live Tool capacity, which adds the ability to perform mill type operations without need for additional setup and handling, improving the quality and cost of your heavy industrial fabrication.
