Workhead Spindle:

  • The cartridge spindle in work head is supported by P4-class precision double roller and angular contact ball bearing.
  • Designed to shorten grinding time, improve grinding accuracy and a wide range of grinding applications, the work head can be adjusted angle +15° and -15° ,and is suitable for internal and external taper grinding. Or, you can choose from:
    • Manual rotating angle type, for grinding internal and external of cylindrical and taper
    • Automatic rotating type (B axis) (X,Y,Z,B) (optional),for grinding internal and external
    • Angle positioning control type (C axis) (X,Y,C、X,Z,C) (optional),for grinding cam or eccentric hole.

B axis for JHD-3205 series only:

  • This is high accuracy rotary table with the design of double leads and bearings, it is suitable for heavy grinding procedure and continuous process.
  • Occlusion area reaches 35%~45%.
  • Good abrasion resistance with no need to adjust backlash within 2 years.
  • Maintains accuracy within 0.003mm.
  • Repeatable positioning accuracy can be reached 0.001mm to satisfy fast positioning & repeatability for production grinding requirements.
