Mounted drill VS 20 B

Primary range of drilling machines are VS32B and range 20 - it means V20B - bench design, VS20B - pillar design and VR4/20B - gang design - set of four drilling machines on one table. Both mark of these machines: they combine thein havy duty frame with operational reliability. They are designed for drilling, reaming and thread cutting in both single-part and series production. The frame is formed by a cast-iron baseplate with a firm steel pillar. The headstock and the bracket with a revolving angular table are vertically adjustable and revolving 360° on the pillar.

The drive of gearbox is realised by means of a V-belt which can be tightened. The machina is eqiupped with 15 speed steps. The speed changes are realised by two hand revers in combination with the V-belt. The four power feeds are shifted by a hand lever, switched on and off by the lever of the automatic coupling. The automatic feed disconnection is set in motion with blunting or breaking the tool. The feed may also be switched off manually any time. The drilling depth is set on a milimetr scale. The spindle seeated in ball bearings returns into the upper position by a spiral spring.

The headstock is lubricated by a circulation pump installed in the headstock. The angluar table enables camping of the workpiece in the vertical as well as horizontal plane. The electric equipment is concetrated in a box on the side of the machine. It protects the motor against short-circuit and the whole machine against the spontaneous start after a voltage loss. The electric equipment complies with the EU-regulations.

The cooling liquid is supplied to the workplace by the electric pump situated in the foot of the machine. The liquid circulates in a closed circuit and is controlled by a cock.
