Absorbing current advanced design and manufacturing technology,optimizing design method, executing  current newest accuracystandards of our state and configuring advanced function units,with high-tech mechanical-electrical integration, CQ5240B new-typedouble-column vertical lathe realizes strong-force cutting withlarge torque on structure property, high dynamic and staticrigidity of machine, favorable earthquake resistance and highreliability. Geometric accuracy of the machine reaches to domesticpreceded level.  

Advantage:

a. high quality casting iron, a super rigid machine withbig machining capacities, stable structure and high machiningefficiency.

b.manual fine scraping(high precision)

c.Working table adopts hydrostatic guide way.

d.the spindle adopts zwz which got wear resistant

e.gear was made by quenching way which got little noise

f.the machine is equipped with vertical tool heads with highprecision digital readout system(DRO).

 Characters:

a. The framework is scrapped by hand which has high geometricaccuracy. In order to increase the lubrication oil reserve anddecrease the friction coefficient.

b. The spindle adopts the world famous brand "ZWZ" with highaccuracy double-row short cylindrical roller bearing take theeffect of centering in the process of running or rotating, becauseradial clearance of bearing is adjustable; the worktable has higherrotation accuracy.

c. The cutter head device is composed of cutter head slide baseand ram. The ram prefer the ductile iron because of its ability towith stand shock loads, high tensile strength, and abrasiveresistance.

d. All gears in adopt harden and grinding processing and havethe advantages of stable drive, low noise. The gears adopt 20CrMnTi through hardening and grounding.

e. After the process of anneal and turning. The guide rail andworktable scrapped by hand sealed by oil slick to make sure thatthey can run steadily.

f. Screw robs (THK) at the crossbeam prefer the processinghardening and tempering. All screw rods at the storage are kept bysuspended way which can make sure it is hard to deformation.
