摘要： A CNC tapping machine includes a spindle to which a tap is attached and a spindle motor for rotating the spindle. The load torque acting on the spindle motor that is detected when performing a tapping procedure without a workpiece is stored in a memory as referential, torque data. During a tapping procedure, a detection device detects the load torque acting on the spindle motor. A computer computes the difference between the load torque defected by the detection device and the referential load torque and uses the difference as the cutting load acting on the tap. As a result, the cutting load torque acting on the tap is accurately detected.

摘要： In a tapping unit according to the invention, the tap is held in a tap-carrier which is screwed into a pattern retained and fixed against rotation in a casing. The tap, the tap-carrier and the pattern form a subassembly mobile with limited amplitude in axial translation and radial displacement inside the casing, so that the tap can follow unwanted movements of the part being tapped.

摘要： Disclosed is a tapping control system capable of performing tapping work with high accuracy and reliability in a manner such that rotation of a tap by means of a digital spindle motor (1) is synchronized with axial drive of the tap by means of a servomotor (2).A digital control circuit (5), used to drive the spindle motor, is supplied with a speed command from position control means (4). The speed command is based on a distributed pulse from an interpolating circuit (3a) for linear interpolation in accordance with the pitch value of a screw to be worked, and a feedback signal indicative of the rotational position of the spindle motor. Also, a servo-circuit (12) for the servomotor is supplied with a distributed pulse from the interpolating circuit. Thus, the two motors are driven synchronously.According to an aspect of the present invention, the tapping work is performed in a fixed cycle such that forward and reverse rotations of the two motors are repeated to reciprocate the tap.According to another aspect, switching means (7) is used to intermittently deliver the distributed pulses and the feedback signal, for selective tapping operation.

摘要： Apparatus for adapting a high speed, drill press type tapping head for use with a CNC vertical milling machine and specifically to a three-piece apparatus that will maintain proper rotation-free alignment of the tapping head housing in both the movable automatic tool rack and in the spindle of the mill. A forked flange secured to the tapping head housing engages a vertically depending shaft attached to a vertically movable, non-rotating part of the mill to prevent rotation of the housing when the tap is rotated by the mill. The opposite side of the tapping head housing supports a short horizontal shaft that engages depending forks on a member attached to the assigned location of the tapping head in the movable tool rack.

摘要： A tapping machine provided with a quill for rotatably supporting a spindle which holds a tap on one end thereof, a reversible electric motor for rotating the spindle and axially reciprocating the quill, an overload release clutch mounted in a power transmitting mechanism which is disposed between the quill and the motor, for suspending the power transmission between the quill and the motor when an overload is applied on the quill, and pulse signal generating means mounted between the clutch and the quill in the power transmitting mechanism for generating one pulse signal in response to each one pre-set unit distance of the quill during the forward motion thereof. The tapping machine performs a working cycle in good order wherein the spindle advances from the start position while being forwardly rotated until the number of pulse signals generated from the pulse signal generating means accords with a pre-set number and returns while being backwardly rotated back to the start position. The tapping machine is also provided with means for generating overload sensing signal when an interval between any two pulse signals from the pulse signal generating means exceeds a predetermined time duration, so as to backwardly rotate the motor immediately after the generation of the overload sensing signal, that is, an abnormal condition warning signal for returning the spindle to the start position.
