Abstract
A machine tool head for machining internal surfaces of a cavity defined by a monobloc caliper for a disc brake assembly. The tool head is an angle head comprising a cutter for machining said internal surfaces and a drive train configured to connect the cutter to an actuator. The cutter comprises a first cutting edge configured for cutting as the tool head is moved in a first direction and a second cutting edge configured for cutting as the tool head is moved in a second direction.
Claims18
A machine tool head comprising:
- a cutter for machining internal surfaces of a cavity defined by a monobloc caliper for a disc brake assembly;
- and
- a drive train configured to connect the cutter to an actuator;
- wherein the cutter comprises:
- a first cutting edge configured for cutting as the machine tool head is moved in a first direction;
- and
- a second cutting edge configured for cutting as the machine tool head is moved in a second direction.
A machine tool head comprising:
- a cutter for machining internal surfaces of a cavity defined by a monobloc caliper for a disc brake assembly;
- and
- a drive train configured to connect the cutter to an actuator, wherein the drive train comprises:
- a spindle configured to connect the drive train to the actuator, wherein the spindle defines a spindle longitudinal axis about which the spindle is configured to rotate;
- and
- a gear train configured to connect the spindle to the cutter;
- wherein the gear train comprises a first arm, and a second arm;
- wherein the first arm is configured to provide a driven connection between the spindle and the second arm, and the second arm is configured to provide a driven connection between the first arm and the cutter;
- and
- wherein the first arm is configured to increase a distance between the spindle and the cutter in a direction of the spindle longitudinal axis.
A method of machining internal surfaces of a monobloc caliper for a disc brake assembly using an angle head machine tool that includes a tool head, wherein the tool head has a cutter comprising first and second cutting edges, the method comprising the steps of:
- a) positioning the tool head within a cavity defined by the monobloc caliper;
- b) machining a first internal surface of the cavity in a first cutting operation;
- and
- c) machining a second internal surface of the cavity in a second cutting operation;
- wherein the tool head remains positioned within the cavity between steps b) and c).
