Using Diamond Abrasives
General
In the proper application, diamond abrasives are very effective for cylinder honing. The Rottler Precision
Hone Head brings the cost of diamond honing down to a range that is much more affordable. Competitive
hone heads require the purchase of multiple hone heads to cover the same size range as the Precision
Head. The Rottler system is approximately 1/5 the cost.
Because of the long life of diamond abrasives the cost per hole of diamond abrasives is approximately 1/5
of the vitried abrasives.
Diamond abrasives in combination with the Rottler Precision Honing Head make a very rigid honing
head. The system will do an excellent job of truing tapered or out of round holes with little or no operator
attention. An operator can set the roughing and nishing loads and expect the machine to hone the
cylinder to size unattended with little or no attention. It is important to use proper stone pressure when
using diamond abrasives. The roughing motor load setting should be in the 0 - 60% range. The nishing
load should be set in the 15 – 25% area. Generally, the higher the roughing motor load reading the faster
the stock removal. The lower the nishing load is set, the more accurate the bore will be.
Mounting Stones and Brushes on Stone Holders
When mounting stone and brushes on stone holders make certain that the
stones or brushes to be mounted are clean and burr free. Place the stones or
brushes in the stone holders so that they are ush with the bottom of the holder.
Tighten the retaining screws by hand.
Do not exceed 36 in lbs (4nm) of torque on the
retaining screws. Exceeding 36 in lbs (4nm) of
torque could cause the stone holders to crack.
Note: Warranty is voided if torque values are exceeded of if non Rottler
stones or brushes are used.
