Hydro-Precis grinding machine retrofitting

– Project Details – Our Job

  • Convert this old conventional grinding machine into a CNC machine
  • Design a new enclosure
  • Install a Marposs In-process measurement system
  • Install a pneumatic internal diameter grippers
  • Check all the mechanisms and mechanical parts

The tree pictures above show the original machine before the retrofitting starts. As you can observe, thousands of hours of hard job make a retofit necessary to sustanin productivity, safety and quality to the maximum. Modernization of many electrical and mechanical parts besides checking al mechanical parts were our goal in this project.


It is usual to sketch a raw drawing of the machine for helping engineers in the process of sizing electrical wiring, sizing cable chains, make drawings of anchoring points and detect colisions.
