CNC Live Centers with Replaceable Tips

CNC Live Centers with Replaceable Tips


CNC Live Centres have heavy-duty bearing arrangement that is designed for high-load, high-RPM conditions prevailing on CNC machines. For this, three different bearings are used with effective preloading. These bearings are lubricated for life using speciality grease. To prevent entry of coolant and machining dust, an effective labyrinth type seal is used. All these unique features contribute towards reliable, dependable and economical solutions for work-support at tailstock end. It helps to get work done more efficiently on lathe machines, copy-turning machines, and CNC turning machines. TIP (Bullet) wear during machining the jobs with centre support, is an inherent problem associated with every live centre. This causes higher run-out and damage to centre holes of the jobs machined. Moreover, productivity is reduced due to higher downtime. A special Allen Key is provided for tip replacement. During the replacement the bearing arrangement is not disturbed.

  • Live Centres have heavy-duty bearing arrangement that is designed for high-load, high-RPM conditions of CNC lathe machines.
  • Three different bearings are used with effective preloading.
  • Bearings are lubricated for life using speciality grease.
  • Use of labyrinth type seal completely prevents entry of coolant and machining dust.
  • Live Centres are manufactured in Morse tapers MT3, MT4, MT5 and MT6.
  • Prashtech offers choice of various shapes of Tips viz. Standard, copying, pipe and custom-made.
  • Such tips can be used as spares with the live centre of respective sizes.
  • Highly profitable to use during mass production of parts.
  • Super precision live centres and those with higher speed ratings can also be manufactured on request with MOQ.
  • Maximum concentricity error after tip replacement is 0.0075mm that can be easily improved by changing orientation of tip while fitting it.
  • The crux of the design of Prashtech centres is to reduce ‘on-load’ deflection of tip for getting controlled ‘on-load’ run-out (TIR) on the parts machined. Design incorporated by Prashtech is superior to alternative designs available in market.
  • Centres having Tip replacement facility are designed for versatility combined with much higher load carrying capacities.
  • Each centre undergoes on-load running-in test at Factory using load set up before dispatch.
  • Centres are compatible to CNC machines operating parameters.
