HS-CNC – Hollow grinding machine in 3 sizes

The HS-CNC series is used for double-sided hollow grinding of household knives, sport and hunting knives, steak knives, pocket knives etc. Grinding wheels are angled at 45° relative to the grinding axis to ensure consistent grinding width for the life of the wheels.

Features

• CNC-controlled feed axes of the two grinding heads with integrated compensation of the grinding wheel wear
• Quality improvement and higher performance due to backlash-free and high-precision linear motion guides
• Double the non-grinding speed and triple the acceleration reduce the non-grinding time by 70%.
• Any conceivable shape of the knife shoulder can be easily programmed
• CNC control SINUMERIK ONE
• DialogPLUS programming software with automatic radius calculation
• Automatic program generation by scanning the contour of the workpieces with the Teach-InPLUS software
• The modular design enables an interlinkage with other machines (e.g. serration grinding machine WS-CNC), thus allowing to configure manufacturing cells for complete machining.
• Integration with different robots systems (SCARA or 6-axis robots) and magazines to suit the customers‘ requirements
• The machine is industry 4.0 capable
• The circumferential speed of the grinding wheel is freely programmable
• Automatic loading and automation systems with stack, chain or cassette magazine
• Technology support, error analysis and troubleshooting by SIEPMANN teleservice

Grinding Wheel Wear Compensation

Measuring the Grinding Wheel Height

Since the grinding wheel is subject to constant wear during grinding, the grinding wheel is re-calibrated after each grinding process.

This is achieved by approaching the grinding wheel towards the diamond of the respective gauging pin.

As the diamond is approached the structure-borne noise is measured and interpreted as a limit value by a noise meter and an evaluation unit installed in the control cabinet.
 

Advantages

•    Significantly reduced sensing time due to short paths
•    Less maintenance and repair due to the elimination of mechanical moving parts
•    Full repeatability of CNC programs due to minimum wear of the diamond.

 

Teaching device

When setting up a new workpiece type, the workpiece contour must be rescanned.
The control generates the corresponding CNC program in the background.
The complete workpiece contour is captured by means of a teaching device and translated into an executable program by the control system.
If the teaching device is not in use, it can be mounted in a "parking position".
