Camshaft grinding machine
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.

1. Super high precision direct-driven work head:
(1) Moveable work center spindle with built-in Renishaw encoder.
(2) Chuck load capacity 150Nm
(3) Precision angular contact ball bearing
(4) Roundness≤1μm
(5) Large rotary angle
(6) Cooling liquid in the center
(7) Driven by permanent magnet synchronous motor
(8) Positioning stop function
The high rigidity work head with moveable work center, is supported
by high rigidity and high precision angular contact ball bearing
and cone roller bearing, which make the spindle the most stability
and extreme stiffness.
Cone chuck MT-4 is used in the spindle, with a φ24mm center hole,
where the tension device of fixture can pass through, as well as
the cooling liquid.
The work head is driven by a Sodick digital AC servo motor, with
variable speeds. Irregular parts can be ground, owing to the quick
and precise spindle positioning, and interactive X axis and C axis.
2. Flexible work head design:
The work head is fixed on a rotary base, with a rotary angle of
-45°to +45°.
Cooling liquid is distributed to work head, tail stock, and
grinding wheel head through a distributor, to keep the machine in
thermal stability to the most extent.
The edge of worktable datum is designed right beneath the spindle
center, which can avoid the heat of cooling liquid influences the
worktable. The work head is equipped with air floating device.
