Quick Details


1. Features

The CNC double column VTL model CK5250-2 is a super rigid machine with big machining capacities, stable & rigid structure, heavy job load and high machining efficiency.

Functions:  1. I.D. turning, O.D. turning, end-facing,

                  2. cone turning,

                  3. grooving, parting / cut off,

                  4. drilling, boring, reaming,

                  5. curve cutting,

                  6. threading, etc. 

2. Machine Body

The main body of the machine is made of high rigid resin castings with vibratory stress relief (VSR) aging treatment. Small cast iron bodies are hardened with high temperature. All the steel parts are thermal refined.

3. Machine main structure

DC75 kW main motor with precision speed regulator or AC 55 kW main motor with VFD unit and gear box are adopted for drive of the table so that infinite variable speeds can be achieved within each speed range. Double row cylindrical roller bearing is equipped under the table. The cone inner ring of the bearing can eliminate radial clearance effectively for high precision and stable machining at high speed. Precision ballscrews are used for drive of tool head vertically & horizontally.

4. Hydrostatic working table

Features of hydrostatic table adopted with constant flow synchronous pump:

a. low friction for permanent life of table,

b. heavy load capacity on table,

c. oil film between machine base and table absorbs cutting vibration & loads,

d. a safety mechanism controls the hydrostatic pressure for optimum safety. 

5. CNC system, control panel & electric cabinet

Siemens 828D s.l. CNC controller with reliable electrics (mainly ABB, Schneider, Siemens) is equipped on the machine. Centralized operation button and control panel stand is fitted for easier operation (German tech.)
