Supplier high precision V4C/V4S Vertical CNC Lathe
Product Introduction
Perfect unity of high processing performance and small floor space,
suitable for processing of auto parts such as hubs, brake discs,
flywheels etc. and soft and hard turning of bearings, the turning
instead of grinding could be realized. The double tools for up and
down surfaces of brake disks turning could be realized at the same
time in the case that the auxiliary shaft is equipped, improving
the processing efficiency and precision level extremely.

cutting fluid
2.Optimized core structure
Provide different processability, form and layout of cutters to
ensure perfect cutting effect.
Feeding system: driven by servo motor, X axis and Z axis are
directly connected with the ball screw through flexible coupling.
The ball screw is installed with one end for fixing and the other
end for support to avoid screw elongation due to the temperature
rise in operation which may cause longitudinal deformation and
achieve high rigidity, high speed, high durability and long life.
Main transmission structure: the main motor can be placed directly
on the lathe body, which can provide better processing rigidity.
| Various cutting conveyor belts |
| | Chain type | Scraper type | Magnetic scraper | Double chain type |
 | machining materials | Steel, copper, aluminum,
carbon and other metal
and non meta | Aluminum, cast iron, etc. | Steel, cast iron | Steel, carbon, and other metal and nonmetal |
| Rear chip removal | Operating
environment | Applicable to all kinds
of chips such as rolls,
lumps, and blocks | Applicable for
continuous conveying
of breakers and chips | Applicable for conveying
of steel and cast iron with chips a length of less than 150 mm in
wet processing | Applicable for conveying of lump metal or non-metal that is
difficult to be discharged by ordinary chain type chip conveyor and
to the situation of large amount of chips |
 | Nitrogen balance system minimizes the movement impact of Z axis
Compared with previous hydraulic balance system, nitrogen balance
system has the following advantages: No external power equipment is
needed, saving energy;
Adapt to rapid smoothly lifting and lowering in high speed; without
noise; improve weight balance and correct the disadvantage of
hydraulic system;
Dramatically promote precision and smoothness in processing,
eliminate micro vibration, and extend the life of screw and motor. |
