• The wheel spindle is supported by 20kg/cm² high pressure oil at axial and radial direction.
• This design eliminates contact-friction between metals without the need to replace parts. Outstanding features of the spindle include high rigidity, high accuracy, long service life, minimum vibration and low heat growth, etc.

Work Head - Maximum Rigidity! High precision!

• The cartridge spindle is supported by 8 P4-class angular contact ball bearings and roller bearings at front and rear end. This assures outstanding machining stability and makes the machine ideal for heavy duty machining.
• FANUC servo motor drive.
• The spindle provides centering and synchronized motion functions. Fast interchange between center and chuck.
• The work head permits 90° counter-clockwise swiveling and 30° clockwise, making the machine suitable for various grinding modes.

HYDRAULIC TAILSTOCK

• The sleeve movement is hydraulically operated for convenient workpiece loading and unloading.
• With foot pedal to control workpiece clamping and unclamping.
• Workpiece clamping and unclamping force can be adjusted by burning a knob. The sleeve is precision machined from hardened alloy, featuring maximum wear resistance and rigidity.

ONE-PIECE FABRICATED BASE

Deformation-free
• The machine base is one-piece manufactured from Meehanite cast iron, tempered for maximum stability of material.
• Box type base construction features superior stability and rigidity.
• The base permits fast coolant exhaust, preventing thermal deformation from influencing machine accuracy.

WHEELHEAD FEEDING SADDLE

Equipped with 0.0005mm Linear Scale for Feedback Control
• The wheelhead moves on double "V" slideways.
• Top slideway surfaces are coated with Turcite-B and precision scraped.
• Equipped with high resolution 0.0005mm linear scale for close-loop feedback.

HYDRAULIC PRESSURE SENSOR

• The pressure switch provides pressure sensing function. The spindle can't start until lubrication oil pressure reaches the setting value. In case hydraulic system is abnormal, spindle runnign stops.
• When setting pressure, fast response can be achieved in case pressure error is within 5kg.

HIGH PRESSURE OIL SYSTEM

• The high pressure oil system includes high pressure filter can, accumulator, pressure switch, check valve and throttle valve. Pressure can be adjusted in axial and radial direction.
• In case power failure occurs, the accumulator may keep pressure for 5 minutes.

AUTOMATIC LUBRICATION SYSTEM

• All moving and running parts are lubricated by automatic lubrication system.
• The lubrication system is separately mounted from the machine to avoid mounted from the machine to avoid vibration and facilitate heat dissipation.
