FEATURES

  • Automatic Hole to Hole and Automatic Roll Over System – The optional Automatic Hole to Hole System allows a complete bank of cylinders to be honed unattended, combined with the optional Automatic Roll Over Fixture, the complete V block can be honed unattended. This will substantially increase productivity with 50-70% labor savings over any manual honing machine. Imagine a cylinder honing machine running unattended while the operator performs other jobs!
  • Automatic Lower Crash Protection System – Many Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders.  Every time the H70 starts honing a cylinder, the machine will check that the stones will not interfere with lower bore before starting rotation and stroking.
  • Vertical Stroking System – CNC Servo Controlled High Pitch Ball Screw and Hardened Steel Linear Slideway System allow precision vertical stroking and fully automated operation.
  • Automatic Load Control – A must for cylinder honing! ‘Load’ is used to describe the pressure that the honing stones press against the cylinder wall while honing. Roughing cycles require higher loads for faster stock removal and finishing cycles requires lower loads to reduce distortion. The H70 is programmed with roughing and finishing loads and automatically controls the stone pressure while honing the cylinders to give perfect geometry and surface finish in every cylinder.
  • Automatic Plateau Brush Finish Program – the machine automatically expands plateau brushes to programmed load and counts down number of plateau strokes, then withdraws the brushes and retracts to the clearance position.
  • Automatic Zero Position Setting System – The machine will automatically expand the stones to a preset load and allow the operator to set zero position, this features allows the operator to calibrate the hone head to different diameters very fast and consistantly taking out the guess work or feel.
  • Automatic Stone Feed-out System – once hone head is positioned in the bore, the hone head rotates slowly and expands the stones similtaneously, once the stones have contacted the bore, only then does the spindle accelerate to full speed and start stroking.
  • Automatic Honing Stone retract at End of Cycle – the machine will automatically retract the stones during last stroke so that the stones do not leave any scratches or marks in the bore.
  • Infinitely Variable – Hone Head rotationa and stroking speeed is infinitely variable to give any surfaces finish and cross hatch requirement – fast.
  • Automatic Cross Hatch Angle System –  the machine will automatically adjust parameters to programmed cross hatch angle and finish the bore to programmed angle.
  • Automatic Roughing and Finishing Load Sensing System – allows the machine to be more aggressivein the rough mode for faster stock removal while automatically reducing honing stone pressure during finish mode operation for precise bore geometryAutomatic Roughing and Finishing Load Sensing System – allows the machine to be more aggressivein the rough mode for faster stock removal while automatically reducing honing stone pressure during finish mode operation for precise bore geometry
  • Electronic Hand Wheel  – used for set up for moving work head from cylinder to cylinder and lowering hone head into each bore. Also used to manually expand stones inside bore.
  • Filtration System and Coolant Tank – Large Capacity 70 Gal (265 Liter) and strong magnetic filter system keep the coolant cleaner and cooler. Optional 2 stage canister filter system allows removal of very fine particles from the honing fluid. Optional external magnetic coolant system increase coolant volume by 30 Gal (115 Liter) and allows easy cleaning. and keep scanister filters cleaner fo rextended life.
  • Rugged Design – Solid Construction – Large, heavy duty base increases the capacity of the machine and ensures a lifetime of rigidity and accuracy. Heavy duty industrial powder coating ensures a lifetime of rust free paint protection and easy cleaning.
  • Quick Change Spindle System – Spindle with ISO 30 Taper and Quick Change System allows hone heads to be changed in seconds with automatically locking system – change form diamond to plateau brush in seconds.
  • Touch Screen Control – The H70 boasts a bright full color, easy to read, ergonomically positioned 15” (400MM) Windows Touch Screen Control that simplifies all aspects of cylinder honing. Precision display in .0001” (.002mm) increments of bore diameter.
  • International Multi Language – Windows Touch Screen Computer Control allows for easy translation into multiple languages.
  • Large Capacity and Versatility – the H75 has capacity to hone form the smallest to large 6 cylinder in-line diesel blocks up to 55’ (1400mm) long. The H75 has 38” (965mm) of X axis travel on linear slideways so that large blocks with cylinder bore centers up to 38” (965mm) apart can be honed – automatically! The H76 can hone very large liners up to 12” (254mm) diameter.
  • Water Based Synthetic Coolant – Water based synthetic honing coolant can be used with Rottler diamond honing stones, greatly reducing heat build up during the honing process. Cost is also substantially reduced over  conventional honing oils and cleaning is almost eliminated. Disposal of used coolant is easy and more environmentally friendly then conventional honing oils.
  • Stainless Steel Doors – Sliding stainless steel doors provide easy cleaning, smooth movement and long life with wide opening for easy loading of blocks. Doors are easily removed for cleaning of machine and changing fixtures.
  • Lighting – 3 LED lights in the cabinet and 2 LED lights under the workhead aluminate the complete work area so the operator can clearly see the honing operation
  • Compact size – Contributes to the reduction of production line space. Can be adapted to transfer line.

CONTROL

There are several important features of the new Rottler H70 computerized control which account for substantial
improvements in accuracy and productivity.
  • The digital bore profile display projects an exact profile of the bore during honing.
  • The computer senses any taper anywhere in the cylinder – top, middle or bottom and automatically dwells or short strokes as programmed, correcting the tight area.
  • Two stage roughing and finishing cycle allows higher loads in the roughing cycle for fast stock removal and light loads for finishing, increasing productivity and accuracy.
  • Infinitely variable hone head speed (1-400 RPM) allows high speeds for roughing and a slower speed for finishing giving the desired cross hatch angle and surface finish.
  • The finishing cycle operates much like a “spark out” system where there is very light stone load eliminating any distortion and resulting in accurate bore geometry and consistent surface finish.
  • Automatic Plateau Mode holds the stones at a preset load and counts down the number of strokes so that each cylinder has the same plateau surface finish.
  • Manual controls are available on the touch screen for fine adjusting settings during automatic cycles and R&D.
