JUCAM CAM GRINDING

Product catalog summary
Overview: The JUCAM series by JUNKER offers advanced OD/ID grinding machines designed for precise grinding of camshafts, cam pieces, and individual cams. These machines are known for their ability to deliver high-quality finishes in a single clamping setup, utilizing a control system with a learning function to compensate for disturbances.
Grinding Process: The machines combine non-cylindrical grinding for cams and cylindrical grinding for bearings. The grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis), using CBN or diamond abrasives for high performance and long tool life.
OD/ID Grinding: Cam geometry is defined in a lift table, with software automatically interpolating values. The cam contour often includes concave areas, determining the maximum grinding wheel diameter.
Key Features:
  • Non-cylindrical OD/ID grinding for various cam shapes.
  • High precision and repeat accuracy with CBN or diamond abrasives.
  • Hydrostatic round guides for long-term precision.
  • Minimized undulations through two-level grinding wheel balancing.
Economical Grinding: The JUCAM series offers efficient grinding solutions with short cycle times and high accuracy, supported by decades of experience in CBN grinding.
Special Solutions:
  • Inner clamping mandrel for precise angular reference in cam pieces.
  • Double workhead for reduced downtime during grinding.
  • Grinding wheel sets for simultaneous grinding of multiple cam contours.
Equipment and Options:
  • Erwin Junker Operator Panel for intuitive control.
  • Axis drive and guidance with hydrostatic feed spindle and direct drive motors.
  • Machine bed made of cast mineral for stability and damping.
  • Automatic compensation for runout and disturbances.
  • In-process measuring system for real-time adjustments.
  • Fire protection and air filtration systems available.
Fields of Competence: JUNKER provides technology centers for demonstrations and tests, a global service network, and energy-efficient solutions. They offer customized production lines and non-standard solutions tailored to specific grinding assignments.
Technical Data: The document includes detailed specifications for various wheelhead versions, dimensions, and capacities of the grinding machines.
