Honing + Superfinishing sticks + Whetstones
     Honing rules

1.

Desirable Cross-hatch Angle

2.

Types of Impregnation

S = sulphur
P = paraffin/oil
T = plastic
Y = sulphur and plastic
Behaviour
The softer the stick,		 - the harder the material
- the lower the pressure
- the higher the cutting performance
- the higher the stone wear and tear.
Always begin with a soft stick and progress to the hardest bond consistent with that which gives a consistently acceptable finish.
3. Sulphur impregnation has these advantages: cooling, good cutting, self-lubricating, passive of cut material, reduces pick-up. Sulphured sticks act harder, therefore select a softer grade than when using unfilled sticks.
4. Normal sticks - adhesive melts at around 80 ° C. The melting point of Sulphur is 119 ° C. If the bonding temperature exceeds 10 ° C, there may be sulphur emission from sulphured sticks, and the benefits will be lost. Ensure that the base is clean and smooth when bonding.
5. The Rt for super-finishing preparation should be < 10 µ.
6. Use a lower viscosity honing fluid when honing hardened steel, grey cast iron and chrome.
7. Always filter the fluid thoroughly.
8. Ensure that Honing Tools are in good condition.
