JUCRANK

Crankshaft grinding made easy

Oscillating grinding 
for all crankshafts. With its JUCRANK pin chasing grinding machines, JUNKER offers a multi-purpose solution for the complete grinding of crankshafts. The range covers all crankshaft types, from single-cylinder to twelve-cylinder. Depending on the processing type and requested release volume platforms and grinding spindle head versions are individually configured and installed for the various JUCRANK types.

Pre- and finish grinding in one clamping

JUCRANK CBN pin chasing grinding machines solve practically every grinding task in crankshaft grinding. Main bearings (cylindrical, convave, convex) and pin bearings (cylindrical, spherical, concave and convex) can be ground in a single clamping. Hardened radii can also be ground. JUNKER also offers practically every combination with other types of grinding. Depending on the machine type combination, locking collars, flanges and pivots can be machined using other JUNKER grinders.

Benefits

  • Flexible applications for various numbers of cylinders with CNC program conversion
  • Oscillating grinding principle creates extra flexibility when grinding main and pin bearings
  • High utilisation ratio with CBN and oil
  • Dressing device and dressing process in line with requirements
  • High dimensional accuracy with in-process measurement
  • High accuracy thanks to 
one-time clamping
  • Measurements can be taken and roundness and dimensions can be corrected during grinding
  • Thanks to the principle of grinding of the main and pin bearings in one clamping, the deviation is theoretically zero.
  • "Sensitive" workpieces supported on the main bearing with self-centering three-point steady
  • CNC-controlled coolant feed guarantees permanent alignment with the grinding zone
  • High long-term precision with hydrostatic circular guides (guide along X-axis, feed-in spindle, axial bearing)
