with accuracy of IT6 and IT5.
The longitudinal travel of the worktable and the in-feed of the wheel head are carried
out hydraulically or manually. The rapid approach and withdrawal of the tailstock center,
the lubrication of the worktable slide-way and the in-feed lead screw etc,
are all hydraulically controlled.
The electro system have been designed according to the CE standard All the electro
parts adopted world brand or Chinese famous brand, such as the Siemens, schneider,
Delixi, Juche, etc.
For AHD model, the spindle elevating motor adopt Servo motor made in Japan ( Panasonic),
and controlled by Siemens PLC. The operator can set the Auto working
(feed rate and times, spark grinding times by the control
panel. When finish grinding, the spindle will lift up auto.
The high precision spindle unit is well designed and produced high load resistible,
mounted in pre-loaded angular deep-groove ball bearing ensures low-vibration
operation, high accuracy, increased lifetime, and low maintenance
The vertical lift lead screw is made in Taiwan,
Name: SHYH MINMACHINERY The Cross feed screw is Ball
scre( SGA30~40 series), make sure the smooth moving.
AC motor drove the cross screw by timing belt thenrealize auto intermittent feed.
The spindle Motor, Y axis drove Motor, a
nd other important parts, Are all made by famous specialty manufacturer,
SHVH MIN, Juli, Shuanglin etc...
Carefully painting. Pay more attention to the round corner, straight border.
Elaborate work make the machine with not only good accuracy
but also nice appearance.
The surface grinding machine with pleasing appearance and well designed structure,
the machine is an indeed precision grind equipment for metal working.
Also it can be equipped with optional accessories, such as parallel wheel dresser,
magnetic separate coolant unit, etc
