Abstract
A tool for metal-cutting comprises a holder (3) on which is mounted in its front part (3a) a cutting plate (6) and which is formed together with a base body (2) as an integral unit by being connected rigidly to the base body (2) in the region of its rear end (3b), a perforation (9) in the holder forming a parallel-type spring arrangement so that the holder is resiliently deflectable relative to a support (11) formed by the base body (2), and an adjustment device for deflecting the holder in use as desired.
Claims20
In a metal-cutting tool including a holder having a front end and a rear end, at least one cutting plate receiving means on the holder, a hole through the holder in the region between the frontend and rear end for penetration by a securing screw for securing the holder to a boring bar, the holder being resiliently deformable in the cutting plate receiving part, and an adjusting means for adjusting the deformable part of the holder relative to the boring bar, the improvement wherein:
- the holder comprises a cartridge having a longitudinally extending base body and a deflectable part, said deflectable part having a front part supporting the cutting plate and a rear end, said rear end being rigidly connected in the region thereof to said base body so that said front part is resiliently deflectable relative to said base body;
- and
- a substantially slot-shaped aperture is provided in said deflectable part having a configuration forming a plurality of joints and a plurality of parallel springs in said deflectable part connecting said front part and rear end thereof so that said front part and cutting plate thereon are adjustable by said adjusting means in a direction substantially radially relative to the boring bar.
