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.
Claims18
A machining tool, comprising:
- a tooth having a tooth tip being covered with cutting particles to form a plurality of geometrically undefined cutting portions,
- the tooth tip being designed to be asymmetrical,
- the tooth tip including a longitudinal center axis, a plateau surface, a first connecting surface and a second connecting surface,
- the first connecting surface and the second connecting surface being directly or indirectly connected to the plateau surface,
- the first connecting surface extending 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,
- 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,
- the first tooth tip angle being <0° as seen in a first sense of direction of movement in which the first connecting surface precedes the second connecting surface, and
- the second tooth tip angle being ≥0° in an opposite second sense of direction of movement in which the second connecting surface precedes the first connecting surface.
A method of machining two workpieces of different materials with 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, comprising the steps of:
- 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 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;
- or
- b1. Removing the machining tool from the machining apparatus,
- 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 machining tool (1) in the first sense of direction of movement.
