Slideway cover for grinding machine, etc. - has cover driven synchronously with slide by chain system attached to slide in plane of lead-screw

摘要

By way of example the grinding head (4) of a grinding machine moves in the Y-direction on a slideway (3) which is protected by a telescopic cover (2). The cover is moved synchronously with the grinding head movement to keep the slideway covered by a cable or chain drive system (26) which is attached to the grinding head or two points (28, 29) in the plane of the grinding head elevating leadscrew (9), and whose line of action remains parallel to the slideway. Compensation for movement of the machine column in the Z-direction is provided by a telescopic shape (36) in the cover drive system. ADVANTAGE - Smoother and more accurate movement of machine slide.
