Abstract
A machining tool (1) includes a tooth (3) having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is designed to be asymmetrical. The machining tool (1) thus is a 2-in-1 machining tool including differently designed sides of the tooth tips (4) which are suitable for efficiently machining different materials.
Claims13
A method of machining two workpieces of different materials, the method comprising:
- providing exactly one machining tool, the machining tool including a tooth having an asymmetrical tooth tip being covered with cutting particles to form a plurality of geometrically undefined cutting portions;
- inserting the machining tool in a first orientation into a machining apparatus including a motor;
- machining a first workpiece of a first material with the machining tool in the first orientation by driving the tooth of the machining tool in a first sense of direction of movement;
- and
- a1. Switching the motor to drive the machining tool in an opposite second sense of direction of movement, and
- a2. Machining a second workpiece of a different second material with the machining tool in the first orientation by driving the same tooth of the machining tool in the second sense of direction of movement;
- or
- b1. Removing the machining tool from the machining apparatus, and
- b2. Inserting the machining tool in an opposite second orientation in the machining apparatus, and
- b3. Machining a second workpiece of a different second material with the machining tool in the second orientation by driving the same tooth of the machining tool in the first sense of direction of movement.

A method of machining a ductile workpiece and a brittle workpiece, the method comprising:
- providing exactly one machining tool comprising a saw band, the saw band comprising a tooth having an asymmetrical tooth tip covered with cutting particles to form a plurality of cutting portions, wherein the tooth tip has a longitudinal center axis, a plateau surface, a first connecting surface and a second connecting surface, wherein the first connecting surface and the second connecting surface are connected to the plateau surface, wherein the first connecting surface extends at a first side of the longitudinal center axis under a first tooth tip angle having a first value with respect to the plateau surface, and wherein the second connecting surface extending at an opposite second side of the longitudinal center axis under a second tooth tip angle having a different second value with respect to the plateau surface, wherein the first tooth tip angle is less than 0° as seen in a first direction of movement in which the first connecting surface precedes the second connecting surface, and wherein the second tooth tip angle is greater than 0° in an second direction of movement that is opposite to the first direction and in which the second connecting surface precedes the first connecting surface;
- inserting the saw band into a machining apparatus including a motor;
- machining the brittle workpiece with the saw band by driving the tooth in the first direction of movement;
- switching the motor to drive the saw band in the second direction of movement;
- and
- machining the ductile workpiece with the saw band by driving the same tooth in the second direction of movement.
