Abstract
A tool cutting edge measuring device that is mounted on a horizontal lathe and multitasking machine includes contact type sensors and an arm. The sensors are configured to measure cutting edge positions of tools in a machining chamber and the arm is movable between an advance position and a retracted position. The arm advances into the machining chamber at the advance position and retracts from the machining chamber at the retracted position. The arm has distal ends provided with two branching units branched into the X-axis direction and the Z-axis direction at the advance position and the sensors are mounted to the respective branching units.
Claims4
A tool cutting edge measuring device mounted to a machine tool, the machine tool being capable of relatively positioning a tool post in a Z-axis direction as a spindle axial direction and an X-axis direction as a moving direction for cutting a workpiece in a radial direction, the X-axis direction being orthogonal to the Z-axis direction, the tool cutting edge measuring device comprising:
- contact type sensors configured to measure cutting edge positions of tools in a machining chamber;
- and
- an arm movable between an advance position and a retracted position, the arm advancing into the machining chamber at the advance position, the arm retracting from the machining chamber at the retracted position, wherein
- the arm has distal ends provided with two branching units branched into the X-axis direction and the Z-axis direction at the advance position, and the sensors, each of which measures a different object, are independently mounted to the respective branching units.
