Abstract
The boring head has a fine movement mechanism for the tool support and a counterweight mounted in the tool body. In order to compensate for imbalance during the adjustment of the cutting tool, the counterweight is moved automatically in the opposite direction by means of a transmission device. The tool support, the counterweight, and the setting screw of the fine movement mechanism can all be simultaneously clamped firmly to the clamping organ.
Claims27
A boring head, comprising:
- (a) a tool body;
- (b) a fine adjustment mechanism for adjusting position of a tool support;
- (c) a counterweight, mounted in the tool body;
- (d) a transmission device, adapted to automatically move the counterweight in an opposite direction upon movement of the tool support by the fine adjustment mechanism to provide imbalance compensation;
- and
- (e) a clamping organ adapted to engage with the tool support and the counter weight to simultaneously clamp the tool support and the counterweight when a setting for the fine adjustment mechanism is selected.
