Device description:
The body and components are cast by Milhanna high grade cast iron
FC30, which is artificially normalized heat treatment and then
treated by natural aging. Components are processed by YASDA, MITSUI
SEIKI, TOSHIBA, ELB and other world-class equipment once clamping
processing. Precision size can be up to micron level, to ensure
high precision equipment basic components.
Machine guide rails and precision ball screws are
continuously lubricated by automatic lubrication system to ensure
longer service life and accuracy. The cooling system is separated
from the body to eliminate vibration and favorable heat
dissipation.
Equipped with Siemens 828D CNC automatic grinding system, and
secondary development, man-machine dialogue fool operation, with
many optional equipment to choose.
The grinding feed system is composed of a V and a flat track of
hand-crafted precision shovel, with automatic lubrication system
and C3 level precision grinding ball screw, which can achieve
smooth movement, excellent repeated positioning accuracy and long
track life.
The standard configuration of the grinding wheel spindle is rear
four and rear two bearing structure. High precision dynamic and
static pressure spindle can also be selected, which has the
characteristics of high rotation precision, high dynamic stiffness,
good vibration resistance, high grinding efficiency and good
grinding surface quality. For special work-piece grinding, the
grinding wheel speed can be adjusted, up to 3500 RPM and 60m/s.
The tail seat is designed to be both rigid and robust. A hardened
alloy steel sliding cylinder encrusted in the cast iron body is
designed to carry the MT4 top core. The jacking force of the
sliding cylinder can be easily changed by adjustment knobs at the
rear.
Numerical control system as the standard configuration, after
secondary development, all Chinese operation interface, easy to
use. Equipped with Siemens high performance servo motor, the
equipment CNC system and drive system have better compatibility, at
the same time with automatic sand repair and automatic compensation
function, to ensure the stability and precision of feed and
grinding.
