is a machine of the most advanced technologic level. It is aimed to satisfy the most demanding users seeking an up-to-date, high quality machine tool with a great cutting power, high accuracy and wide range of programmable functions. Broad selections of the machine's alternative executions makes it possible for the end user to opt for the optimal one so as to fit the specific conditions of his.

The WHN 110 (Q, MC) horizontal milling and boring machine belongs to the machine range of advanced generation launched by TOS VARNSDORF a.s. in 1992. The machine range is Hi Tech featured, powerful, and from the optimum performance of an individual machine point of view there is a wide range of executions available. The machine may either be controlled by Heidenhain TNC 426 M or Sinumerik 840 D of Siemens. Application of advanced AC drives of Siemens and electric switchgear and protection elements of world-renown makers (Telem?canique, Simens and other) ensures a long lasting reliability of the machine.

The producer offer the following type alternatives:

WHN 110 - horizontal boring mill with a live spindle and a transversely traveling rotary table
WHN 110 Q - the same model equipped with an Automatic Tool Changer
WHN 110 MC - machine center - the ATC equipped model supplemented with an Automatic Pallet Changing equipment as well

WHN 110 (Q, MC) horizontal boring mill is available with either of two different spindle head types:

type N with the spindle assembly carried up in a double row roller bearings - for higher dynamic load

type R with the spindle assembly carried up in a system of special, spindle type, angular contact ball bearings - for a wider range of the spindle speeds

The emloyed CNC system controls fully the machine's 5 axes (X, Y, Z, W, B) plus the workspindle rotation (C axis). Independent servodrives in all the axes allow for the linear, circular as well as helical interpolation to be exploited.

The machine's rotary table is clamped by hydraulics at its target positions while the other axes are held their relevant target positions by the power of their relevant servo-motors working within the closed positional loop.

Optional equipment:

PVD 112 - spindle leading support (long) - headstock N only
HF 50 (A) - vertical milling head
HUR 50 - фрезерная головка универсальная
clamping devices - cube UK 500 and angle plates UU 800, UU 950, UU 1120, UU 1450
LD 650 - facing head - headstock N only
CHZ 110 - tool cooling kit conventional
CHOV 110 - through spindle tool cooling kit
