| The rotating movement of the
ACME thread spindle (4) with the corresponding guide nut (9)
is converted into a linear movement of the guide table (10).
The guide profile (5) consists of an extruded square profile
with lateral prismatic guides, on which the guide table (10)
runs due to a freely adjustable slide piece (8). The axial
slot in the guide body is closed and kept free of dust with a
cover band (6). |
