The basis of the engraving spindle is a motor with a constant power of 170 watt and a maximum speed of 60,000 rpm. Easy-to-operate mechanics enable the depth of the engraving to be determined. Unevenness in the engraving material can be levelled out by means of a height adjuster which can be preset using spring force. The "lock ability" of the height adjustment also enables "milling work"!
Tool change is via a comfortable knob clamping which is located on the rear of the spindle. The clamping diameter of the engraving spindle is 35mm, and therefore compiles with the diameter of the most common "belt-driven spindles".
Unlike conventional air-operated angular excursion systems, this system works with a powerful high frequency spindle and axis-parallel excursion movements in all three axes.
The main advantages of a high frequency spindle are its high power density and large speed control range. Program-controlled speeds from 5,000-60,000 rpm can be set without any need for expensive compressed air.
The classical use of excursion systems is to burr workpieces with robots. In this application a rotating tool is passed along the contour to be trimmed by a robot. The pressing force is generated either by springs or by pneumatic cylinders. If the pressing force rises above a certain value, the excursion system yields automatically around a pivot. ...
