1 MACHINING APPARATUS HAVING WORK TABLE CAPABLE OF Y AXIS LINEAR MOVEMENT AND TOOL CLAMP CAPABLE OF X-Z PLANE MOVEMENT AND ROTATION

摘要

PURPOSE: A machine tool having a worktable for moving linearly and unidirectionally and a tool rest for plane motion and rotation is provided to form different channels in a substrate by performing unidirectional linear motion of the worktable and plane motion of the tool rest with the single linear motor and turning the tool rest with a low-speed/high-torque motor. CONSTITUTION: A machine tool is composed of a worktable(20) mounting a workpiece; a tool rest(26) mounting a tool for processing the workpiece with relative motion; a Y-axis linear motion unit(22) linearly moving the worktable in the Y-axis direction; a rotating unit(30) turning the tool rest around the Y-axis; and an X-Z plane motion unit(28) combined with the rotating unit to move the tool rest on the plane formed by the X-axis and the Z-axis. The X-Z plane motion unit has a linear actuator moving the object along the X-axis, a first slide block(52) having an inclined surface, a second slide block(54) moving along the X-axis by the linear actuator, and a center slide block(56) moving along the inclined surface of the first slide block between first and second slide blocks.
