<p>#CMT# #/CMT# The machine (10) i.e. CNC controlled, has a work piece spindle (12) rotationally driving the work piece about a work piece rotation axis, and a processing unit that comprises a tool to retain the work piece on the work piece spindle for machining. An adjusting mechanism (26) is provided for causing a relative movement between the work piece spindle and the tool, for enabling loading, unloading or processing of the work piece. A swivel drive unit (28) can rotate the work piece spindle about a swivel axis and a linear drive unit (30) that moves the work piece spindle along a linear axis. #CMT#USE : #/CMT# Machine i.e. CNC controlled, for processing of optical work piece i.e. plastic spectacle lens. #CMT#ADVANTAGE : #/CMT# The parts of a swivel drive unit that do not protrude into the work space of the machine can be separated and/or isolated easily from the work space. The stacked arrangement of a linear drive unit and a swivel drive unit provides a machine with very compact building, which leads to a high rigidity of the adjusting mechanism, thus providing a high processing quality. The utilization of processing unit leads to quicker processing, particularly from a reduction in the auxiliary processing times. The individual machine parts is easily arranged to ensure optimum accessibility for assembly, maintenance and setting operations. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a machine for processing of an optical work piece of plastic spectacle lenses from an angle in front and above the machine. 10 : CNC-controlled machine 12 : Work piece spindle 26 : Adjusting mechanism 28 : Swivel drive unit 30 : Linear drive unit.</p> |
