摘要： There is provided a hole machining method, using a tap tool which rotates about an axis of rotation and which includes a threaded part which has a blade for machining a threaded groove in a pilot hole, and a non-engaging part which forms a space between itself and the pilot hole in a cross-sectional view in which the axis of rotation and a center axis of the pilot hole are aligned, the method including the steps of machining a threaded groove by rotating the tap tool and advancing it toward a workpiece side in a first state in which the center axis and the axis of rotation are aligned, rotating the tap tool about the axis of rotation and moving the tap tool in an interior of the pilot hole toward the non-engaging part side in a direction orthogonal to the axis of rotation to transition the tap tool from the first state to a second state in which engagement between the threaded part and the threaded groove is released, and retracting the tap tool from the threaded hole.

摘要： A tool accessory used to apply different volumes of a cutting fluid to the tap under CNC control by causing the machine to undergo different pump cycles in which the rotational speed of the tool is increased above the tapping rotated and then quickly returned to the tapping rotation. The tool includes a tapping head, a reservoir filled with cutting fluid, a centrifugal force-reactive pump and at least two discharge nozzles. The pump includes a plurality of biased piston springs that are forced outward and store centripetal force when the tool is rotated at speeds above normal tapping speed. When the rotational speed of the tool is reduced, the piston springs overcome the centrifugal forces and force cutting fluid through the discharge nozzles. The volume of cutting fluid discharged is controlled by adjusting the viscosity of the cutting fluid, the tool's maximum speed, by using different size discharge nozzles, and by using different pump cycles.

摘要： A workpiece is rotated by a master motor and a tool is linearly moved by a slave motor to cut a thread in the workpiece. Position feedback of the master motor is multiplied by a coefficient K and the result used as the position command of the slave motor. Provision is made of an angle synchronization learning control unit for storing one pattern cycle's worth of the correction data of the threading and adding the same to the position deviation. This control unit stores one pattern cycle's worth of the correction data corresponding to the position feedback of the master motor. The position is converted to the correction data corresponding to the time at that time based on the stored correction data to find the correction data and this is added to the position deviation.

摘要： A control device which controls a tapping device provided with a feed motor for feeding a spindle in an axial direction thereof and a spindle motor for rotating the spindle about its axis. The spindle installs a composite tool having a boring section for forming a bore in a workpiece and a subsequent tapping section for forming a female thread at the bore. An asynchronous control is initially performed for independently controlling rotation of the feed motor and the spindle motor for boring. If the tapping section reaches the workpiece, a control is switched to a synchronous control for controlling the motors in synchronism with each other.

摘要： A control device for a tool driving unit is disclosed wherein a tool such as a tap or a drill is controlled to be rotated and axially moved by the control device. The tool driving unit has a spindle servo motor adapted to be driven according to a spindle current command and a feed shaft servo motor adapted to be driven according to a feed shaft current command which are provided by a single microcomputer which operates as the control device. The microcomputer reads an NC program and outputs a spindle command for the spindle servo motor when performing tapping, and outputs both the spindle command and a first feed shaft command for the feed shaft servo motor when performing drilling. A thread pitch changing controller for controlling a thread pitch outputs a second feed shaft command for the feed shaft servo motor when performing tapping. A tool selector receives the first feed shaft command and the second feed shaft command and outputs a selected feed shaft command based on the tooling operation being performed. The spindle and feed shaft servo motors are controlled based on the provided command(s) and by detecting actual angular positions and rotational speeds of the servo motors.

摘要： A screw cutting method for use with a numerically controlled machining system is improved by enabling finer finishing of the final screw surface. The invention allows the removal of scars formed during rough machining by offsetting the position of the rough machining passes in the direction of screw cutting, i.e., in the direction of movement of the tool during cutting, so that during the final finishing pass, more material is removed from the screw surface opposing the cutting direction. Surface finish is further improved by specifically controlling the cutting depth in the cutting passes just preceeding the final cutting pass.

摘要： A machine tool with a spindle for machining a large-diameter workpiece in that a servo motor for moving a spindle in the axial direction and a variable reluctance motor for rotating the spindle are installed in a housing, and a synchronous controller for synchronizing and driving the above-mentioned servo motor and the variable reluctance motor is provided. The variable reluctance motor has a characteristic in that a large driving torque can be obtained in a low rotating speed. By using a variable reluctance motor as a spindle motor, therefore, it is possible to obtain a large torque without providing a large size motor, and also possible to realize a large-diameter machining by a small-size unit.
