CNC Plunge/Angular Cylindrical Grinder

Hydrostatic Bearings

The wheel spindle is supported by 20kg/cm2 high pressure oil at axial and radial direction.

Without the need to replace parts

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.

Hydrodynamic Bearing

  • The spindle is supported by oil membrane, as almost without metal contact between bearing and spindle, the spindle is less wearing and has a long and lasting life.
  • The oil membrane between bearing and spindle increases contact area, and therefore, workpieces can reach the highest precision and roundness.
  • Oil menbrane absorbs vibration during grinding process,the workpieces will be kept the best surface roughness.
  • The wheel spindle is supported is supported by 3kg/cm² low pressure oil at radial direction.
Work Head


Spindle transmission system

  • Belt tension force is resisted by fix bushing.
  • The spindle pulley is equipped with buffering pad.

Hydrostatic bearing/ Hydrodynamic bearing

  • The instant impact force caused by motor starting is absorbed by buffering pad.
  • The impact force does not directly affect the wheel spindle.
Hydraulic Tailstock


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 feaures superior stability and rigidity.
  • The base permits fast coolant exhaust,preventing thermal deformation from influencing machine accuracy.
One-piece Fabricated Base


WHEELHEAD FEEDING SADDLE

  • 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.


Touch probe gauge

  • Measure the position and calculate the distance
  • Measure the position

Auto in-process gauge

  • Measuring workpiece OD, grinding and measuring simultaneously, improve production yield.
  • Inspecting workpiece roundness after grinding, and feed back to controller.
  • Inspecting workpiece accuracy after grinding.

Automatic grinding wheel balancing system

  • Grinding wheel automatic balancing while rotating.
  • During machine operation if grinding wheel unbalancing, the device automatic adjust wheel balance, it has no need to dismount grinding wheel.

Crash control

  • When over grinding workpiece, grinding wheel immediately retract, to avoid machine damage.
  • While grinding, the audio frequency function can shorten rapid traverse time, improve grinding efficiency.


WORK HEAD Maximum Rigidity! High precision!

  • The catridge 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 dive.
  • The spindle provides centering and synchronized motion functions. Fast interchange between center and chuck.
  • The work head pemits 90°counter-clockwise swiveling and 30 ° clockwise,making the machine suitable for various grinding modes.
Hydraulic Pressure Sensor

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 turning a knob.
  • The sleeve is precision machined from hardened alloy, featuring maximum wear resistance and rigidity.

Hydraulic pressure sensor

Hydrodynamic

  • 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 running stops.
High Pressure Oil System

Hydraulic pressure sensor

Hydrostatic

  • 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 running stops.
High Pressure Oil System

Hydrostatic Bearingsl system

  • Hydrodynamic: The hydrostatic bearings system includes high pressure filter can, accumulator, pressure switch, check valve and throttle valve. Pressure can be adjusted in axial and radial direction.
  • Hydrostatic: 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 vibration and facilitate heat dissipation.
  • With oil constant temperature cooler.
