ABSTRACT:
An apparatus and a method for controlling machining chip and the length of such chip make use of a lathe tool support on which an electromagnetic tool mount is disposed. The electromagnetic tool mount comprises a front clamping block and a rear clamping block for holding a machining tool. An electromagnetic coil located between the front and the rear clamping blocks is provided at the center thereof with a throgh hole for receiving the machining tool. The resumption and the interruption of power supply to the electromagnetic coil are regulated by the amplified signals sent out by an oscillation controlling circuit. The magnitude of power voltage and the cycle of power resumption of the electromagnetic coil are so adjusted as to facilitate the magnetization and the demagnetization of the machining tool. The machining chip is broken by a magnetically induced thrust and a shearing force generated by the rotation of the machining tool.
