Sell Vertical Machine Centers

Features:

1) Integral construction made of high grade cast iron

2) Internal stress is removed by way of heat treatment so as to

make sure of an endurable precision of the best rigidity

3) A square sliding rail is used for the main shaft to greatly enhance

both stability and shock resistance

4) For the sliding rail, the lubricating points are averagely distributed

and arranged and a volumetric oil injector is used to make each

of the oil injecting points equal and the lubrication of the sliding

faces uniform

5) A C3 grade precise screw-bar is used with the main shaft to

match with the pre-press of the screw cap and the pre-pull of the

screw-bar for the pre-removal of both back space and temperature

rise caused stretch

6) The screw-bar of the main shaft is fitted with a P4 grade precise

bearing for a best axial rigidity

7) The main shaft is fitted with a high rigid P4 grade bevel-angle ball

bearing by way of precisely grinded assembly to make sure of the

best dynamic rotating precision and duration

8) The structure is designed into oil-water separation and the sliding

rail's oil is collectedly recovered, in line with the requirement for

environmental protection
