618 Direct-coupled main shafts for surface-grinding machine






Application:

for 168 series high precision manual molding surface-garinding machines、internal cylindrical wheelhead



performance & characters:

1. Noiselow vibrationhigh precisionhigh rigidityand low

temperature.


2. Direct-coupled design for motor and main shaft.(the motor and shuft are no

longer driven by belt or junction box)hence no power lossout strong

cutting capacitylow vibrationhigh gmoothness for cutting surface and

high precision.


3. With high precisionGrade P4double row rollerballbearing from

japan,field installation up to dimension for the best precisionrigidity and

long service life.


4. Japan-made high rigidity chrome and molybdenum alloy steel for main

shaft material, high precision and resistance after quenching and

temperingstengthen treatmentsurface HRC55-60and precision

grinding.


5. Complete precision dynamic balancingincluding motor rotorgives

the best performance and highest grinding precision and brightness.
