High precision CNC step down grinder-H3
Device description:
1. 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.
2. 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.
3.Equipped with Siemens 828D CNC automatic grinding system, and
secondary development, man-machine dialogue fool operation, with
many optional equipment to choose from, including inner hole
grinding device, automatic end measuring device, automatic outside
diameter measuring device, etc.
4. 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.
5. 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.
6. 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. Special accessories oil pressure tail seat with a pedal
to facilitate unloading work parts.
7.Siemens 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.
Intelligent grinding solution
● Four-axis segment difference grinding machine is equipped with
three-axis manipulator loading and unloading mechanism to realize
batch processing of components.
● Online measuring system, to ensure the accuracy of long
unattended.
● The first centering type workpiece clamping device in China, in
the grinding process to obtain superior concentricity.
● Rough machining and finishing shaft effectively match, through
the diameter difference to get the best accuracy and surface
finish.
● The control system and software independently developed by Hotman
can realize the quick editing and creation of the workpiece.
