Dressing grinding wheels offline allows manufacturers to use their grinding equipment for production, reduces set up time, improves quality, and ultimately increases throughput. Manual contour dressers are operator-dependent and inconsistent, affecting the quality of the grind and increasing scrap rates. Utilization of a contour dresser generally requires more frequent dressing, reducing the lifespan of the wheel and increasing consumable costs.
The DM-9CNC Wheel Dressing Machine is a stand-alone machine that provides operators with the ability to dress grinding wheels while the grinder is in production. Available for 9 and 10-in. diameter wheels, the machine CNC dresses precision contours in vitrified grinding wheels. The shape can be transferred from a CAD drawing into G-code which the DM-9CNC can read to form the wheel. Alternatively, for simpler geometry, the operator can enter the dress profile in a tabulated form on the 15-in. touchscreen HMI. A diamond plated dress roller is powered by a high-speed brushless servo motor offering high torque and closed-loop velocity control up to 10,000 RPM. Additionally, two-axis servo-driven slides use a 0.1-micron glass scale to precisely position the dress roller.
