5. THE MAIN STRUCTURE
LATHE BED
The lathe bed has been cast into firm cross form by the iron material
numbered HT200 with little vibration. Two 90 degree V-type level guide
rails are hardened by
hyper acoustic quenching and well grinded.
Both apron and tail stock have one 90 degree V-type level guide rail.
The longitudinal feeding (Z) is transmitted by ball screws which is
fixed before the lathe bed. The main motor is built in the foot stand.
HEAD STOCK
The lathe bed has been cast by the iron material numbered HT200, it
is fixed firmly on the lathe bed by four screws. In the headstock, the
spindle is fixed on two conical roller bearings (7210, 7212 ), the
spindle bore is 38 mm, the taper of the spindle bore is MT 5. The
triangular belt is used on the lathe, the advantage is non-noise when
the lathe is running at any speed.
APRON
The apron has been cast by the iron material numbered HT200, its
surface of sliding rails are well grinded, there is no clearance between
apron rails and the level rails of the lathe bed, its lower sliding parts
can be conveniently adjusted. The top slide is fixed on the apron, its
sliding on the apron is transmitted through the ball screws, the apron
slide clearance of the dove tail slot can be adjusted by moving the fit
strip.
