Knuth 5HP 20” x 8” HFS 52 NC Automatic/Semi-Automatic Surface Grinder with Dressing Cycle 122415

Description

The HFS NC series is a solution for automatic and semi-automatic surface and flute grinding. This machine offers advantages in terms of precision and efficiency thanks to grinding cycles that can be easily programmed via the touchscreen and the automatic grinding wheel dressing mode. This can be inserted into the machining cycles and compensates dimensions and speed fully automatically. The option of switching between semi-automatic and automatic operation also extends the range of applications from repair workshops and training to series production.

Features

• This machine is designed for continuous operation at high machining speeds and features quiet operation, maximum accuracy, and minimal heat-buildup for guaranteed optimum work results
• Dual guides for linear table motion
• Grinding spindle head and Z-axis run in precision linear guides on preloaded ball screws
• Servo drives on Y- and Z-axis and hydraulic linear table movement can be adjusted via an infinitely variable electronic proportional valve for precise and consistent feed
