NUM has a great deal of experience in grinding applications and is one of the world’s leading suppliers of CNC solutions for tool grinding. NUM also supports external and internal cylindrical grinding, including non-circular grinding, surface grinding as well as centerless cylindrical grinding, with CNC systems specially tailored to the respective application. Each application solution offers corresponding cycles and a matching and easy-to-use HMI.

NUMgrind for Surface Grinding (Surface Grinding Pack 1) is suitable for all aspects of the surface grinding process. It offers a complete “off the shelf” solution, with embedded grinding and dressing cycles governed by a user-friendly menu-driven data entry system that includes 3D simulation and wizard-guided setup.

In short, NUMgrind not only saves OEMs years of development time, but also significantly reduces operators’ training time.

NUMgrind HMI Surface Grinding

The Flexium CAM-based programming process is extremely user-friendly. Entry screens provide the machine operator with a comprehensive graphical programming approach that depicts the grinding wheel, workpiece, and associated setup data in a clear and concise manner. Operators do not have to use ISO or G-code programming; they simply fill in the data fields presented by the program. After completion of the data entry session, the grinding program is automatically generated, stored, and is then ready for execution.

NUMgrind Surface Grinding Cycles

The grinding cycles are designed for a 3-axis (X/Y/Z) grinding machine. The packages include the following features:

Grinding Cycles:

• Slot Grinding Cycle (with and without oscillation)
• Surface Grinding Cycle

Auxiliary Grinding Functions:

• Wheel Surface Speed Calculation
• Manual Measurement
• Emergency Retract Sequences
• Fixed 2 Diamond or Profile Dressing Roller Wheel Dressing
• Fixed 2 Diamond Dresser Wheel Shaping
• Part and Dresser Setup Routines
• Wheel Data Management (Eight Stored Setups)
• Semi-Automatic Mode (Automatic oscillation along X and if needed Z axis, manual operation on the Y axis)

Wheels:

• Straight Wheels
• Special Profile Wheels (by Profile Dressing Roller or 2 Diamond Dresser)
