LOCH - Deep Hole Drilling Machine TB 1

Deep Hole Drilling Units are used chiefly in special machine building, in transfer lines, or with a separate base, as an independently-operating single machine. The main area of application lies in the automobile and commercial motor vehicle industry with their vendors. Likewise, the aviation technology, medical technology and, more and more, the general mechanical engineering, invests into highly precise low drill machines. The gun-drilling system is used here. The units are manufactured with 1-,2-,3-,4-, 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 machines guarantee productivity and drilling accuracy with great ease of operation on years:

  • Drill spindle drive with frequency-controlled drive, each spindle separately propelled
  • Feed by frequency-controlled servo-drive with absolute encoder
  • Feed spindle designed as backlash-free recirculating ball-screw
  • Drill spindle as precision-stored guide dipping spindle with life span grease lubrication. High precision is placed surely by the linear guidance combined with rolling elements.
  • Tool failure safety devices for best possible tool protection 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

LOCH - Deep Hole Drilling Units and Machines of the range TB 1/E

Distinguish themselves by their robust construction giving long servicelife. An optimally designed module system permits all conceivable machine variations within short delivery times. The permanent inflow of the most modern machine-building techniques in construction and manufacture is a guarantee of high-performance and modern plants. All requirements related to drilling capacity and accuracy, combined with suitable drilling tools, can be met for years. Used either as a unit in the building of special machines or as standard or special Deep Hole Drilling Machines – we guarantee the reliability of all our machines.
