LOCH - Deep Hole Drilling Plant

Deep Hole Drilling Plants are mainly found in the automobile industry for high quantities, and its suppliers. The BTA-, as well as the gun drilling system is used here. The units are manufactured with 1-, 2-, 3-, or 6-spindles, since the compact design combined with an ingenious module system has proved to be extremely reliable.
The following special features of these units or plants guarantee productivity and drilling accuracy with great ease of operation for years.

  • Drill spindle drive with frequency-controlled drive, each spindle separately propelled and equiped with a belt failure monitoring
  • Feed by frequency-controlled servo-drive with absolute encoder
  • Feed spindle designed as backlash-free recirculating ball-screw
  • Precision bearing spindle with lifelong librication
  • Tool failure safety devices for best possible tool proteciton in different versions
  • Strongly connecting rigid welded structure in a compact construction for an increase in the endurance of the tools
  • Short times for retooling and reduction of the machines secondary processing times
