Product Information

Ultraprecise grinding tool

HAL-LP Plate

The main feature

  • Fixed whetstone Canada with super-minute whetstone
  • Neither the high processing speed, super flatness nor the slurry go out
  • The disadvantage of a past fixed whetstone is canceled by adopting a super-minute whetstone

Loose and Converntional fixed abrasive
