Built-in Motor Spindle with housing diameter 120 is the mainstream for high speed machining.
There are 4 types for Built-in Motor spindle with housing diameter 120 which are all Flanged type, M3-LMSN / M3-LMSNA / H4-LMSN / H4-LMSNA.
H4-LMSN, tool holder is HSK40E, hydraulic tool exchanging.
H4-LMSNA, tool holder is HSK40E, pneumatic tool exchanging cylinder.
M3-LMSN, tool holder is BT30, IOS30, BBT30, hydraulic tool exchanging.
M3-LMSNA, tool holder is BT30, IOS30, BBT30, pneumatic tool exchanging cylinder.
The features of Built-in Motor High Speed Spindle with Housing diameter 120 are high speed machining, high efficiency and low noise. Each type can have the motor with different power specifications, and can be optional with FANUC coil.

H4-LMSNA, Built-in Motor High Speed Spindle with Housing diameter 120, tool holder is HSK40E, pneumatic tool exchanging cylinder, Max. speed is 24,000 rpm.
M3-LMSN, Built-in Motor High Speed Spindle with Housing diameter 120, tool holders are BT30 / IOS30 / BBT30, hydraulic tool exchanging, Max. speed is 30,000 rpm.
M3-LMSNA, Built-in Motor High Speed Spindle with Housing diameter 120, tool holders are BT30 / IOS30 / BBT30, pneumatic tool exchanging cylinder, Max. speed is 24,000 rpm.
a. Water-Repellant Ring (Patented)
For this spindle type, every spindle has a water repellant ring to effectively repel any cutting fluids away from the spindle to prevent anything from splashing into the labyrinth area during high speed cutting.
b. Labyrinth Design with Air Seal
During high speed operation, positive air pressure coming out from the labyrinth prevents any contamination from entering into the spindle.
c. Highly Efficient Helical Cooling Channel
The compactly designed helical cooling channels effectively dissipate heat from the stator coil and bearings to reduce the effects of thermal deformation on precision.
d. Anti-Rotating Gripper Guide Ring (Patented)
During acceleration and deceleration of the spindle, the patented gripper guide ring design eliminates any unusual noises and vibration of dynamic balance.
e. Inspection of Precision of Every Spacer
Every spacer is inspected for precision to assure unanimous quality of every spindle.
f. PCB Model Type Made With Stainless Steel
Suitable for clean room operation, the PCB model type is made with stainless steel to allow the use of a water cooling system.
g. Hardness Test of Critical Parts
After heat treatment, the critical parts undergo a hardness test to ensure they have the correct hardness in order to reduce their risk of damage during operation.
h. 3-Plane Dynamic Balancing
To effectively decrease vibration, we conduct dynamic balancing calibration at 3 different planes.
i. Test of Isolation Grade of Stator Coil
Testing the isolation grade of the stator coil ensures stable electronic drive control and long operational life.
