JUPITER

Centerless cylindrical grinding

At JUPITER, grinding means less cylindrical grinding, with CBN too on request. JUNKER combines this cylindrical grinding method with CBN wheels to create significant productivity advantages, especially with large batch sizes. This is coupled with the simultaneous abrasion along the entire grinding wheel width, which ensures considerably reduced machining times for both large and small-scale production.

The JUPITER grinding principles

There are two principles for less grinding: feed-through grinding and plunge-cut grinding. JUPITER can achieve both principles.

Feed-through grinding applications:

Bolts and bearing supports, large rings, smaller rings, piston components (e.g. for compressors), shafts with constant diameter, piston rods (e.g. for shock absorbers), small pistons for hydraulic and injection systems, precision wires and rods, piston bolts.

Plunge-cut grinding applications:

Rotor shafts, gearbox parts, bearing surfaces of camshafts, pipe components for composite camshafts, cardan joints, needle components for injuction systems, valve shanks, spherical rollers.

The JUPITER 200, JUPITER 250 and JUPITER 500 come available with a full or partial enclosure.

Benefits

  • Very high abrasion rate
  • Simultaneous grinding of various diameters (plunge-cut grinding)
  • Automatic loading and unloading with integrated loading system (plunge-cut grinding)
  • Automatic passage of a workpiece flow (feed-through grinding)
  • High utilisation ratio with CBN abrasive and emulsion or oil as cooling lubricant
  • Dressing device and dressing process in line with requirements
  • Comprehensive after sales service
  • Increased productivity with taper correction: Regulating wheel can be re-indexed if the grinding wheel exhibits uneven wear. This allows a higher number of cycles before the next dressing cycle.
  • Machine’s full protection cover opens on both sides and is pre-fitted for connection to a grinding mist extractor
  • Vibration-free torque transfer to the grinding spindle through installing the main spindle drive outside the machine
