  • Product Overview

    The Model 4000 incorporates state-of-the-art technology in the machine's design. The machine utilizes a system of round hydrostatic ways on the X, Y & Z axes and a substantial C-axis assembly which minimizes machine deflection during the grind cycle.The hydrostatic components increase the machine's accuracy, rigidity and overall grinding speed. These special ways use an oil film under pressure between moving parts to minimize friction, increased damping, stiffness and mathematical accuracy.

  • About Company
    Unison Corporation

    Unison Corporation offers a complete line of standard and custom-made grinding machines. Our products feature both manual and computer controlled CNC equipment. We are one of the leading designers & builders of high precision grinders and are recognized worldwide for our expertise in the field of grinding. Unison was founded in 1959 and designed the patent to the DedTru® Centerless Grinding Fixture. During the 70's, Unison was one of the pioneers in the field of computer controlled grinding equipment. In fact, in 1976, we installed the first computer on a grinding machine which was the genesis of our TruFlute® line of equipment. Our early experience with computer controls established a base of knowledge which evolved into our proprietary state-of-the-art computer control known as the Unison Programmable Controller (UPC). Today, the UPC is used in all of our CNC machines together with our user friendly software with its real-time graphic three dimensional (3D) parts simulator. Unison continuously invests in research & development to discover new methods for solving grinding problems. Our efforts have resulted in the development of extremely accurate grinding machines which produce round parts, helical fluted tools, rotary files, burrs, end mills, ID/OD round and non-round profile tools.
