US 5,331,870 A · Apparatus and method for use in controlling machining chip and length of such machining chip

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.

Dependent claims

An apparatus for use in controlling machining chips and the length of such chip while using a machining tool against a moving workpiece comprising

a lathe tool support;
an electromagnetic tool mount mounted on said lathe tool support;
an oscillator circuit electrically connected to said electromagnetic tool mount;
said electromagnetic tool mount including
a set of clamping means to receive and position the machining tool on said lathe tool support stationary relative to said support, said machining tool engaging said workpiece to produce machining chips,
and an electromagnetic coil adjacent said clamping means electrically connected to said oscillator circuit,
said electromagnetic coil having a hole centrally therethrough receiving the machining tool therethrough;
said oscillator circuit receiving power from a connected power supply and including
an oscillator means for generating an electrical oscillation signal to control a periodical alternating interruption and resumption of electrical power to said electromagnetic coil;
said electromagnetic coil magnetizing the machining tool when electrical power is delivered through said oscillator means and the machining tool demagnetized when no electrical power is delivered to said electromagnetic coil to magnetize a machining chip causing a magnetically induced thrust and a shearing force to cause the machining chip to be broken by such forces.
