APPLICATION GUIDE
Pressure • Light to medium pressure is recommended for most operations
• Avoid excessive pressure which may result in wheel deformation & damage to the work surface
Feed speed
• Feed speeds directly affect the number of pieces completed over a given period of time
• Slow feed speed reduces the number of workpieces completed, while producing a shorter
scratch pattern
• Slow feed speed allows for longer dwell time & permits more work to be done on each piece
Conversely, a fast feed speed increases the number of workpieces completed
• While producing a longer scratch pattern
Oscillation
• Oscillation may be used to break up scratch lines
• Produce a more uniform finish
• Additionally, an increase in cut may be experienced
• A general starting point for oscillation is 3/8” amplitude at 200 cycles per minute
Lubricants
• Lubricants, such as water, water soluble oil & straight oil, will decrease the heat generated while
running, improve the luster & improve the surface finish
• The higher the viscosity of the lubricant, the lower the surface finish (RMS value) produced
