Ametek Precitech Freeform MGG produces intersecting grooves

Precitech, part of the Ametek group of companies, has introduced its Freeform MGG micro-groove generator, which is said to be optimised for machining intersecting grooves on flat surfaces that are used typically in the production of retro-reflective materials.

The Freeform MGG can machine a part up to 600 mm with a guaranteed groove depth variation under 3 micron. According to Precitech, what sets the machine apart from other grooving machines on the market is its contouring vertical axis.

"This makes it a true freeform machine and its potential applications are virtually limitless," says Dr Jeff Roblee, vice president of technology. "For example, you could mount a Levicron spindle vertically and use the machine as an ultra-precision mill, or a Fast Tool servo for making variable depth grooves."
