Main Application and Features
Optimal solution for grinding medium-sized rolls, high-precision low-roughness working and supporting rolls of the metallurgy, paper-making and rubber industries.
The longitudinal travel of work table effected hydraulically with the infinitely variable speed, also transmitted by the hand wheel.
The plastic-coating guideway used in the work table with hydro-static lubricating.
Based upon the modeling structure built in the right of table, the upper table runs along against the modeling ruler, executing the convex and concave profile grinding of roll-barrel.
While the modeling structure come off, able to turning to normal cylindrical roll and roll-journal grinding. The traverse of wheelhead is with the hydraulic rapid approach & withdrawal, auto-intermittent cycle and manual micro infeed functions.
The hydro-dynamic-static bearing is adopted in the spindle of wheelhead.
The workpiece rotates in infinitely variable speed driven by AC frequency-inverted motor.
The wheel dressing device mounted on the rear of the tailstock.
The machine is equipped with the coolant tank which with the magnetic separator and paper-filters.
According to user’s need, capable of furnishing with auto-measuring device to measure the diameter, roundness, cylindricity of workpiece and the shaping error of roll, and further through the data processing, typing out the error data.
