摘要:
The insert comprises a first layer of soft, stroke dampening elastic material and a second layer of harder, noise deadening material. The layers are interposed between an abrasive tool (11) and the oscillating arm (20) of a rotary head of a calibrating machine. The two layers consist of two complementary, adjacent elastic elements (13, 14) of which the lower (13) is securely attached to the abrasive tool (11). The upper layer (14) provides a means (12) for fastening to the oscillating arm (20). The two complementary elements (13, 14) are so shaped as to provide respective facing, fitting surfaces (13a, 14a) arranged to reciprocally lock the two elements (13, 14) in a given plane and allow reciprocal sliding in a direction which is perpendicular to said given plane.

摘要:
A diamond segment or insert (10) for the cutting of hard materials and provided with dead holes (11) formed in one of its faces and shaped and distributed in such a way that all the cross-sections perpendicular to the longitudinal axis of the tool originate full surfaces whose areas are all substantially equal to each other and in a constant ratio with the area of the rated cross-section of the tool, whatever the degree of wear of the tool may be; the holes (11) have a depth greater than half the thickness of the tool and are disposed on the disk or the tool (12) intended to be used for the cutting alternately turned through 180° with respect to each other; the holes (11) may be filled with an aphonous abrasive or superabrasive material.
摘要:
A diamond-set segment of insert (11) is provided with a plurality of through bores (10) between its side (12) and/or front faces (13, 14); the bores (10) can be left free so as to improve tool cooling during machining by virtue of the fact that the cooling liquid passes through them, and at the same time allow better discharge of the removed material; alternatively they can be filled with mixtures of resins and diamond dust or other abrasive or non-abrasive metal elements, so as to improve the surface of the cut material by acting against it during cutting.
