SPINDLE UNIT

AUTO TOOL COMPENSATION
With the feedback data of machined hole diameter, the unit automatically compensates its tool nose position to maintain hole diameters within a tolerance.

Features
The compensation mechanism is designed thin to minimize the distance from the front bearing to the toll nose.
The compensation mechanism is incorporated not in the boring arbor but in the slide adapter, in which the boring arbor is mounted. This allows the spindle unit to be used for a wide range of applications from small-diameter boring to large-diameter boring.Additionally, the spindle unit does not require a special arbor;therefore, arbor change is easy.
The simple mechanism enables the spindle unit to assures stable machining accuracy.
The pulse motor for compensation is separated from the spindle rotation part so that the spindle can rotate at a speed up to itself limit.
The spindle adapter travels in linear motion,which is the ideal movement for compensating the cutter radius by a correct amount.
Retracting the tool on completion of machining prevents the tool from putting a tool-mark on the workpiece.
