Before Installation
Processing with a pneumatic feed unit
Reasons for Installation
- Need to shorten processing takt time using simultaneous 4-axis processing with diamond tools.
- Need to reduce processing takt time by making it possible to change requirements during processing.
- Need enough rigidity to prevent any chatter from the seating face while spot facing.
- It is our goal to avoid a significant mark-up in price in comparison to pneumatic feed units.
Results of Installation
- NC control shortened the actual processing time.
SSV5 type: 20.9 sec
Pneumatic feed unit: 53 sec - The slide is no longer needed with the 300 mm stroke.(Actual processing 190 mm)
- When installing a multi-axis head and bush plate, dangling is minimal and centering is easier.
- The lifetime of tools is prolonged and the operating costs are reduced.
- The change in the number of rotations completed by the program enabled processing under optimum conditions.
- NC control and precision ball screw enabled stable feeding.
- NC control enabled shorter time for start-up of machinery (adjusting time).
Processing requirements
Drilling with low feed rate→counterbore
Clearing film of the die casting low feed rate F = 210 mm/min
Profile machining unit High feed rate F = 300 mm/min
Drilling unit 1,000 min -1 (V = 34.5 m/min)
Counterbore unit 800 min -1 (V = 65.3 m/min)
