Machine for milling out the header bores and for milling the penetration curves on supports which are welded to headers

摘要

Bed - torsionally rigid welded construction Headstock - for setting: - bore diameter of header tubes - tube diameter during the milling of support ends Main spindle - with work fixtures Three-jaw chuck - for internal and external chucking Clamping fixture for headers - semi-tubes are aligned and clamped - tubes are clamped in V-blocks - the eccentricity of the header bore is determined by longitudinal displacement of the tube Main spindle drive - infinitely controllable by direct-current motor via worm and bevel gearing Carriage - guided on hardened shafts in ball bushings Milling head - pivotable with milling unit Pivot drive - pivoting range 0-45 DEG via crank disc or electronic control Copying slide rest - adjustable with hydraulic copying device by means of spindle and handwheel Hydraulic unit <IMAGE>
