Rotary Coordinate Drilling SPM for dia 2,000 mm is developed for an ancillary of L&T. This is a forced thru-coolant enable deep hole drilling machine for Ø 35 mm x 400 mm deep holes. The servo motor driven rotary table with T slot has an accurate pitch positioning capability through the direct encoder feed back . The pitch selection, program selection, program editing etc are facilitated by a user-friendly HMI interface. The vertical axis movement and automatic job clamping, de-clamping are facilitated by hydraulic system.

The capacity of the above shown Knurling SPM is designed to accommodate shafts of Ø10 mm min. to Ø50 mm max x 500 mm long.

• Longer shafts can be accommodated either through suitable extension of admit between centers or through a hollow chuck.
• Cross traverse (traverse for the knurling wheel to plunge) is upto 150 mm through hydraulic cylinder.
• Ball screw & box nut for longitudinal axis movement, in combination with case hardened male sliding surfaces & turcite for female sliding surfaces will provide smooth, back-lash free smooth sliding movement, apart from wear resistance.

An AUTO-CYCLE, operated through the combination of direct, encoder based feedback of servo drive for the longitudinal axis, PLC, feed-end limit switches, sensors etc, ensures that the knurling operation takes place as programmed with repeat accuracy & with the least human intervention.

Coolant system, lubricants, machine enclosure, automatic chip disposal system, guide way protection etc will be provided at an additional cost. Job loading and unloading will be manual.
