LOCH - Co-ordinate Deep Hole Drilling Machine

Co-ordinate Deep Hole Drilling Machines are used chiefly in mould-, die- and tool-making, as well as for singlepart and mass production.
Depending on the application, gun drilling tools are used for deep hole drilling work, and also BTA tools in special cases.
By the use of a special tool-carrier with steep taper seating, it is possible to produce all conventional processes such as spot-facing, thread-cutting, milling, etc., in addition to deep hole drilling. It is thus possible to carry out even complicated sequences of operations on one workpiece in one clamping.
The following special features of these Co-ordinate Deep Hole Drilling Machines guarantee productivity and drilling accuracy with great ease of operation over many years:


  • Drill spindle drive by frequency-controlled drive
  • Feed of all axes by frequency-controlled servo-drive with absolute encoder
  • Feed spindle designed as backlash-free re-circulating ball-screw
  • Precision bearing drill spindle with lifelong lubrication
  • Guide system with hardened and ground steel guide rails combined with preloaded rolling elements (almost wear-free and without stick-slip effect)
  • Large vertical adjustment range of the unit at the slide, without foundation works

LOCH - Co-ordinate Drilling Machines

The most modern CNC-Control with Clear Text Fault Diagnosis provides a frictionless and fault-free sequence of operations. Whether the machine units are used for single-part or mass production, we guarantee the reliability of all machines built, where the following accessories and special accessories still extend the manifold employment possibilities:

Machine tables The machine tables axis of rotation can optionally also be fitted as a NC-axis

Clamping equipmentBy mounting centering tailstocks or counter-rotating tailstocks, the Co-ordinate Drilling Machines can also be used in combination with self-centering steadies for drilling centric bores in symmetric-rotating parts

Feed controlHighly sensitive drill breakage safety device, plus coolant control devices, for tool-monitoring, to switch off the machine, giving signals before overload and return to initial position

Feed equipment Combined with gantry loading equipment or pallet systems, the machines are also suitable for operator-free use

Drilling units Pivoting by option about +/- 20°

Other optionsComplete cover of the machine, separate high-efficient milling and screw thread cutting spindle, online-service
