Either (1) a front side of the knife body has a cutting edge, the front side of the insert is removably mounted to a rear side of the knife body, and either (A) a rear side of the insert has a cutting edge, or (B) the rear side of the insert has a blunt face that forms a rear side of the knife; or (2) a rear side of the knife body has a blunt face that forms the rear side of the knife, the rear side of the insert is removably mounted to the front side of the knife body, and the front side of the insert has a cutting edge.
摘要:
A clamping assembly to hold a woodworking knife in place in a woodworking machine. The clamping assembly comprises a clamping component comprising a body and an actuator. The body has three discrete contact positions distributed thereon: 1) a fulcrum located generally at one end, 2) a knife abutting portion located generally at the other end, and 3) a bearing surface located elsewhere. The actuator is for applying a clamping force to the body along a clamping axis located intermediate of the knife abutting portion and the fulcrum. The fulcrum is a surface having a normal that is at an angle to the clamping axis . The bearing surface is a surface wherein a line normal to the bearing surface intersects the line normal to the fulcrum at a position outside of the clamping component at a location farther askew of the clamping axis than the fulcrum.
摘要:
A wood working knife (32) for use in a wood working machine, comprising a knife body having a first cutting edge (34) and an opposed second cutting edge (36), the knife body having a first clamping surface (40) and a second clamping surface (38). The first clamping surface has opposed clamping features (48,50) separated by a middle section (52), the opposed clamping features and the middle section being sized and shaped such that, upon the knife body being inserted into a clamping assembly, the clamping forces are localized towards the opposed cutting edges and away from the middle section.
摘要:
An inserted milling cutter comprises a plurality of blade grooves in the outer periphery of a milling cutter body, back seats received in the blade grooves, blade body pressed against and fixed to rear surfaces of the blade grooves in the direction of rotation by the back seats, and means for fixing the back seats. Means for correcting a change in cutting radius when the faces of the blade body are ground is constituted by a first inclined surface formed on a blade groove bottom surface and a second inclined surface formed on the back seat which abuts against the first inclined surface.
摘要:
Milling tool (10) comprising a main body (11), at least a blade (12) and at least a clamping element (13), including a threaded hole (23) for the insertion of screw means (14), and arranged in a hollow (15) made in the main body (11), in order to clamp, by means of the screw means (14), the blade (12) against a wall (17) of the hollow (15). The clamping element (13) has a front surface (25) arranged in abutment on the blade (12), a part of the front surface (25) is inclined, in use, by an angle (α) with respect to a plane (A) orthogonal to the axis (x) of the threaded hole (23).
