Centerless cylindrical grinding in finish quality with the TITAN 500

The JUNKER portfolio has been extended to include a new machine concept. The TITAN 500 is able to grind workpieces to a finished standard of quality using the throughfeed grinding technique. This entails workpieces passing through the machine in continuous sequence, while they are precision ground by a wide CBN grinding wheel.

To achieve this high standard of quality, the TITAN features a wide range of machine attachments such as wheelhead, regulating wheelhead, work blade and infeed/outfeed which are aligned and calibrated to an extreme degree of precision. Another key factor in the achievement of final quality workpieces is a high degree of machine rigidity using a vibration-damping, highly torsion-resistant cast mineral machine base designed specifically for CBN grinding.

Centerless cylindrical grinding machine TITAN 500

Grinding example with the TITAN 500:
Centerless grinding of piston pin outside diameters in finishing quality

Centerless grinding of piston pins in finish quality
Centerless grinding of piston pins in finish quality

Qualities achieved:
(The data may differ depending on the workpiece and the machining sequence)

  • Diameter tolerance: < 0.005 mm
  • Cylindrical shape: < 0.0012 mm
  • Surface roughness Ra: 0.0001 mm
  • Concentricity: < 0.001 mm
  • Cycle time: 3.0 seconds
  • Machine availability: > 95 %
  • Throughfeed rate: 2 m/min
  • Grinding allowance: 0.3 mm

Your benefits at a glance:

  • Rough and finish grinding to final product quality take place in a single grinding operation (no intermediate handling)
  • High output through short cycle times due to centerless throughfeed grinding
  • High level of concentricity due to market-leading machine rigidity and the use of CBN grinding wheels
  • High stock removal rate due to the patented automatic adjustment of the work blade
  • Machine availability > 95 %
