REAMING

Cone Reduction Factor (Blind Holes) When burnishing blind holes, the cone must not extend past the end of the rolls. If it does, the cone will collide with the bottom of the hole. Each burnishing tool has an adjustment range of:

• Approximately 0.5mm on diameter for tools below 12.7 mm • Approximately 1.0mm on diameter for tools above 12.7 mm

D

For through hole burnishing tools, the standard cone value "x" is 1. If the standard cone is used for blind hole burnishing, the only way it will not extend past the end of the rolls is to reduce the length of the cone. The required length reduction is dependent on the set diameter versus the minimum capable diameter of the

BURNISHING tool. The factor of reduction (x) can be calculated using the formulas below and will be a whole integer number ranging from 2 - 8. The "x" value could result in a decimal figure. If so, round down for answers below 0.80 and round up for answers 0.80 and above.

Diameter (5.89 mm - 12.77 mm)

Diameter (12.64 mm - 127.94 mm)

Diameter (127.90 mm - 165.90 mm)

x = 1 + Z - Y 0.05

x = 1 + Z - Y 0.10

xx = 31 + Z - Y 0.10

Z = diameter of the hole Y = minimum diameter setting of tool

Z = diameter of the hole Y = minimum diameter setting of tool

Z = diameter of the hole Y = minimum diameter setting of tool

Example: Z = 11.05 Y = 10.71mm

Example: Z = 17.76 Y = 17.40mm

Example: Z = 148.20 Y = 147.90mm

x = 1 + 11.05 - 10.71 0.05 = 7.8 which is approximated at "x" = 8 Correct Cone: RSTH-038-11025

x = 1 + 17.76 - 17.40 0.10 = 4.6 which is approximated at "x" = 4 Correct Cone: RSTK-034-00044

xx = 31 + 148.20 - 147.90 0.10 = 34
