DM-9CNC

Wheel Dressing Machine

The Glebar Advantage

For position feedback, other CNC dressers often employ rotary encoders. In such a setup, the servomotor shaft position is reported by the encoder, and this plus the pitch of the motion screw is used to calculate slide position. Even with a precision ballscrew, there is error between this calculated position and the actual slide position -- especially during direction changes -- due to backlash, friction, compliance, etc. As the mechanics wear, the position error gets progressively worse. Dressing a circular contour with only rotary feedback is a nightmare, since doing so  requires coordinated motion with multiple direction changes. The DM-9CNC uses linear encoders attached directly to the slide, ensuring accurate positioning under all conditions so the resulting contour is always true to form.

Introducing the DM-9CNC

  • The DM-9CNC is a standalone machine, available for both 9" and 10" work wheels, that CNC dresses precision contours in vitrified grinding wheels.
  • The roll dress spindle on the DM-9CNC is extremely rigid and precise, with runout less than 0.00005" (1.3 µm).
  • Powered by a brushless servo motor, it offers high torque and closed-loop velocity control at up to 15,000 RPM.

DM-9CNC Highlights

Stable Granite Bed and HMI Controls

Stable Granite Bed and HMI Controls

The DM-9CNC is built on a granite bed for optimal thermal stability and vibration control. The ability to dress wheels offline increases efficiency and minimizes downtime. Having wheels ready for change-over allows the grinder to be used only for its intended purpose -- making parts. Wheel contour can be generated in CAD or entered directly as linear and circular positions on the large 15" touchscreen interface. Dresser path, wheel shape, and dresser position are all rendered in real time on the screen.
