Next Generation Continuous Dress Creep Feed Grinding

The heavy duty Blohm Profimat XT continuous dress creep feed grinder from United Grinding combines exceptional rigidity and power with fast axis speeds for exceptional grinding productivity in machining large parts with high stock-removal requirements.

Posted: February 20, 2019

With table speeds greater than 1,500 ipm, a quick changeover wheel-dresser system and improved acceleration/deceleration rates for optimal positioning speeds and short cycle times, the Blohm Profimat XT heavy duty continuous dress creep feed grinder from United Grinding can produce reciprocal grinding speeds up to 3,000 ipm for fine surface finishes.

With a high precision 12,000 rpm spindle and an integrated 66-position tool changer for efficient machining of multiple workpieces without the need for complete tooling changes, the Mägerle MFP 51 from United Grinding combines grinding with conventional machining operations in one production system with either five or six axes for grinding, milling and drilling operations to process parts in single clampings for improved accuracy and output.

The Blohm Profimat XT heavy duty continuous dress creep feed grinder from United Grinding North America, Inc. (Miamisburg, OH) combines exceptional rigidity and power with fast axis speeds for exceptional grinding productivity. Table speeds greater than 1,500 ipm, along with a quick changeover wheel-dresser 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 ipm 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 Profimat XT excels at machining large parts with high stock-removal requirements.

This machine’s speed improvements increase axis movement by 100 percent 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, a ribbed base and column casting with dual ballscrews for Z-axis cross-grinding stability have been introduced. The machine is equipped with a Siemens Sinumerik 840D sl control that features a touch screen monitor and Windows-based graphical user interface. This machine has been customized with advanced human-machine interface (HMI) to provide grinding process data, machine health monitoring, operational efficiency and graphical product information.

United Grinding also offers the Mägerle MFP 51 that combines grinding with conventional machining operations within one production system. This flexible machine comes equipped with either five or six axes for grinding, milling and drilling operations to process parts in single clampings for improved accuracy and output. In its standard configuration, the MFP 51 includes a high precision 12,000 rpm spindle and an integrated 66-position tool changer for efficient machining of multiple workpieces without the need for complete tooling changes. The machine’s coolant nozzle features two-axis control for full freedom of movement and precise positioning of coolant delivery to the tool and/or workpiece. Through-the-spindle coolant delivery, along with nozzles on the grinding support, optimize coolant delivery. An optional nozzle changer allows for further adaptation of the coolant supply delivery to individual jobs.

An overhead grinding wheel dresser on the MFP 51 is integrated into the machine’s grinding support to shorten process times. Options include an RFID-based identification system for grinding wheels and tools to eliminate errors when entering tool data in the machine.
