Abstract
A holder for a cutting tool for processing of workpieces has a first part for holding a cutting tool (150), a second part (120) to which the first part is fastened, and a fastening element (140). An adjustment element adjusts the position of the first part in relation to the second part. The first and second parts have a first bore and a second bore for receiving the fastening element and a recess (118, 128) for receiving the adjustment element. The first part has an abutment surface (115) placed onto a contact surface (122) of the second part, such that the central axes (A-A) for the first and second bores become parallel. The abutment surface of the first part and the contact surface of the second part are inclined in relation to the feeding axis (G-G) of the work piece towards the cutting tool (150).
Claims11
A Holder for a cutting tool for processing of workpieces, comprising:
- a first part configured to hold a cutting tool;
- a second part to which the first part is adapted to be fastened;
- a fastening element for fastening the first to the second part;
- an adjustment element for adjusting a position of the first part in relation to the second part;
- wherein the first part has a first bore and the second part has a second bore, wherein the first bore and the second bore receive the fastening element, and wherein the second part has a recess for receiving the adjustment element, and the first part has an abutment surface adapted to be placed onto a contact surface of the second part, such that central axes of the first bore and the second bore are parallel;
- wherein the abutment surface of the first part and the contact surface of the second part are inclined with respect to a feeding axis of the workpiece toward the cutting tool, defining an inclined plane;
- wherein a central height of the cutting tool is adjustable by the adjustment element being turnable to define a distance between the adjustment element and the recess in the second part, and wherein turning the fastening element moves the first part along the inclined plane towards the second part and in the direction of the central axes of the first bore and the second bore and towards the adjustment element;
- wherein the adjustment element has a straight portion and a chamfered portion, and
- wherein the second part further comprises a piston adapted to exert a pressure force on the chamfered portion of the adjustment element, to press the adjustment element towards the recess in the second part.
