CNC-driven machine center in particular for processing optical lenses for spectacles, comprising fast tool unit arranged in acute angle with rotation axis

摘要

The unit (10) comprises a basic frame (12) with two crosswise moving carriages (18,22) one of them (22) fitted with the work-piece holding spindle (24). The machining device (28) is located opposite at the frame (12) connected to a fast tool arrangement (36,38) assembled of two parallel positioned and alternately moving shuttles. The fast tool unit (36,38) and the work-piece holding spindle (24) are positioned in an acute angle in order to compensate a possible height deviation of the cutting blades.
