Large Scale High Accuracy Envelope Machining of Hard Materials Using A Johnford Vertical Machining Center - Insaco

For over 60 years, Insaco has been synonymous with excellence in the development and production of high precision machined parts. As a custom fabricator of ceramic, glass, sapphire, and other hard materials, Insaco specializes in machining parts that often require tolerances measured in millionths of an inch, and wear properties that satisfy even the most demanding applications.

Large Envelope Machining with High Accuracy

The Johnford Vertical Machining Center (VMC) is a new piece of equipment acquired by Insaco in response to our customer’s request for larger envelope machining capability. The VMC has a diamond grinding accuracy to .0005” within an oversized 102” x 70” x 30” envelope. In addition to meeting specific grinding tolerances, the VMC has an add- on feature (shown here) with a man-assist crane for handling large ceramic or glass pieces. The VMC works in concert with our Coordinate Measuring Machine which allows documenting critical tolerances with accuracy of down to one half micron.
