摘要： A machine tool includes: a movable body that supports a tool; a feed drive unit that feed-drives the movable body; a numerical control unit that controls the feed drive by the feed drive unit to perform cutting by the tool; an acceleration sensor that is provided on the movable body and detects acceleration of the movable body; and a command unit that outputs a stop command to stop driving of the feed drive unit to the numerical control unit when the acceleration of the movable body exceeds a threshold value set in advance on the basis of an output of the acceleration sensor. The command unit sets the threshold value to a first threshold value in a cutting control state, and sets the threshold value to a second threshold value lower than the first threshold value in a feed control in a non-cutting control state.

摘要： A novel mounting assembly used with an air spindle is described. The mounting assembly includes an insertable top portion for inserting into a mounting collar and to be rotatable therein, the insertable top portion formed with an upper disk shape with a first diameter and a lower disk shape with a second diameter and adjacent to the upper disk shape, an outer circumference of the upper disk shape having a groove formed therein, and the upper disk shape and the lower disk shape having a passage axially formed therethrough perpendicular to the groove. The mounting assembly further includes a sleeve disposed below the insertable top portion, the sleeve defining an opening with a sidewall which is perpendicular to the insertable top portion, the opening sized to hold a spindle, a port inside a wall of the sleeve defining the opening providing fluid communications with the passage of the insertable top portion.

摘要： Electronic spindle lock for a power tool. One embodiment provides a power tool including a housing, a bit receiving portion provided on the housing for receiving a power tool bit, a motor within the housing configured to rotate the bit receiving portion, and a controller coupled to the motor. The controller is configured to enter an electronic spindle lock mode, and detect rotation of the bit receiving portion in a first direction. The controller is also configured to control motor to rotate in a second direction in response to detecting rotation of the bit receiving portion in the first direction.

摘要： A tool carrier assembly for use at a machine tool, which includes at least one workpiece-carrying spindle for rotatably driving a workpiece received in the workpiece-carrying spindle. The tool carrier assembly includes a first slide being movable in a first direction, a tool carrier being supported on the first slide and configured to hold a plurality of tools, a tool drive unit including a tool drive for engaging with one of the plurality of tools held by the tool carrier to rotatably drive said tool, when the tool is arranged at a tool drive position with respect to the tool drive, and a drive mechanism for driving movement of the first slide together with the tool carrier in the first direction relative to the tool drive position, when the tool drive is disengaged with the tool, to relatively move another tool of the plurality of tools into the tool drive position.

摘要： A combined through-hole processing machine includes a working bed provided with two opposite and parallel slide rails on it. A deep-hole processing mechanism is provided on the working bed and includes a pair of sub-spindle heads used to clamp a deep-hole tool respectively to conduct the deep-hole processing on workpiece. A U axis feed unit is provided between the two slide rails and used to provide the feed for the movement in the long axis direction parallel to the two slide rails. A deburring mechanism is provided on the working bed and located at one end side of the deep-hole processing mechanism, which includes the corresponding two chucks and two tailstocks where the chucks are used to clamp the workpiece with the deep-hole processing already fulfilled on the deep-hole processing mechanism respectively and the tailstocks are provided to arrange the deburring tools respectively to conduct the deep-hole deburring action.
