Whats New at Grindal

A new Okamoto PRG8-DXNC Precision Rotary Surface Grinder.

Grindal Company received its new rotary surface grinder in early August. It has an Electro-magnetic chuck and automatic demagnetizer with a working diameter of 31.5,’’ a versatile table swivel of +/-5 degrees & a rotary speed of 20 to 150 RPM and a 10HP spindle.

This machine is not the same as a Blanchard grinder that removes large amounts of stock at a time and levees a cross hath pattern on the surface of the part.  It is a CNC surface grinder with a fixed spindle and rotary table that will give us control to maintain closer tolerances and finer finishs.

It is built on a rigid Meehanite cast base and no table overhang assuring superb accuracy and repeatability. Programming input is graphic conversational with a multi-step grinding up to 4 steps in a single set up.

Designed with 2-axis simultaneous CNC control that expands grinding flexibility, thus it is ideal for single or multiple work piece grinding. It is the perfect machine for high production precision work.

Tolerances: On flat & parallel =/ - .0001

Micro finish: 8Ra or better.

Grindal Company has since 1965 provided our customers with World Class Quality & Service.
