Continuous Dress Creep Feed Grinder

Visitors to UNITED GRINDING’s booth #236802 at IMTS 2018 will experience the new BLOHM PROFIMAT XT. The next generation of heavy-duty continuous dress creep feed grinders, the new machine combines exceptional rigidity and power with fast axis speeds for exceptional grinding productivity.

Table speeds greater than 1,500 in/min, along with a quick changeover wheeldresser system and improved acceleration/deceleration rates, offer optimal positioning speeds and short cycle times. Optional features include table dresser systems, HSK wheel flanges and a linear drive table to produce reciprocal grinding speeds up to 3,000 in/min for fine surface finishes. Additional grinding advances include dual left and right coolant nozzles with the RazorTec® wheel cleaning system.

Applying spindle power up to 80 hp with grinding wheel widths up to 8 in., the BLOHM PROFIMAT XT excels at machining large parts with high stock-removal requirements. The machine's speed improvements increase axis movement by 100% and acceleration/deceleration by 200 percent, enabling overall grinding cycle time reductions of up to 30 percent thanks to fully optimized positioning. To improve stiffness, BLOHM introduced a ribbed base and column casting with dual ballscrews for Z-axis cross-grinding stability.

The machine is equipped with a Siemens SINUMERIK 840D sl control that features a touch screen monitor and Windows-based graphical user interface. UNITED GRINDING customized this advanced human-machine interface (HMI) to provide grinding process data, machine health monitoring, operational efficiency and graphical product information.
