SPINDLE UNIT

MANUAL TOOL COMPENSATION
This spindle unit is provided with the function for manual cutter radius compensation.A dial collar is used to compensate the cutter radius according to the measurements of machined hole diameters.
This unit facilitates fine adjustment not only tool change but also in tool wear compensation. resulting in remarkable increase in production efficiency.
Features
 •The compensation mechanism is the same with that for automatic compensation; therefore, stable accuracy can be obtained.
(Refer to the features of the spindle unit with automatic compensation mechanism.)
 •Since compensation is made by manually turning a dial collar, this compensation mechanism has no pulse motor or control unit for compensation.
 •The rotary joint of the hydraulic rotating cylinder is provided with T-slots for limit switch dogs and an anti-rotating plane, so that you can add a limit switch,as necessary, to obtain the tool release confirmation signal (for initiating the next sequence operation).
