Common Metals to Be Honed
Cast Iron Cylinders. Including(use part if CAN )automotive and truck engine cylinder s,
sleeves, etc. Most manufacturcers reccommend a hone finish of approximately 25 to 35
microinches for ideal setting of rings.
Step 1. Use roughing stones Series 1 to remove stock to within 2-1/2 thousandths of finished
size ( should be honed dry).
Step 2. When polishing stones are not used, use finishing stone Series 3 to remove the
remaining stock in 30 to 40 seconds. Produce 20 to 25 microinch RMS finish .
When finishing step is to be followed by polishing, use finishing stones Series 2 to remove
stock to within 1/2 thousandth of finished size. Average finish obtained is 25 to 35 microinches
Finishing stones should be used dry.
Step 3. Use polishing stones Series 5 and 7 or a stone CANS 4 or 5 to remove last 1/2
thousandth. Average surface finish obtained is 15 to 20 microinches RMS. Polishing stones
should be used wet.
Hardened Cast Iron Cylinder Sleeves. When honing hardened (chilled) cast iron sleeves,
special stones are required (see Stone Selection page). Use standard honing procedure.
Steel Cylinders and Holes. Consult Stone Selection page for proper stones for honing steel.
NOTE: when honing steel, ail stones should be used wet.
Aluminum. The following special instructions should be used in honing aluminum cylinders:
Step 1. If cylinder is scored, remove all built equipment prior to honing, or stones may chip.
Step 2. Stones should be trued with the use of a truing sleeve. Due to the fast cutting action
and stock removal of stones when honing aluminum, stones may not have time to become
properly trued in .be fore final size is reached. For this reason stock must be trued in before
honing (see Truing Instructions).
