Analogue control device for abutment-free stroke limitation of machine tools |
摘要 |
An analogue control device with at least one electric stroke control emitter for the abutment-free stroke limitation of machine tools, especially honing machines, with which either a tool carrier or the workpiece connected to the machine tool carries out a reciprocatory stroke of adjustable length. As stroke control emitter there is provided a simple resistor which is adjustable in conformity with the machining movement and which is passed through by electric current, while pre-set values of the current or of the voltage generated by the current on the resistor are employed for limiting the stroke. The device also includes a warming-up or conditioning control which makes it possible automatically to carry out a predetermined number of working strokes with changed stroke length, the number and/or stroke length being adjustable.
