Specification and Calculation
Makino has established a balance specification of G2.5, or lower, for the
V55 (the lower the specification the better the balance).
The balance specification establishes a range from which a “target bal-
ance”, for a tool at a given rpm, is calculated.
Tooling is then placed on a balancer and the out-of-balance amount or
“unbalance” is measured in grams per millimeter (g·mm). Most balancers
also indicate the area of unbalance. Material is then added or removed to
bring the tool into the required balance specification.
If sending tools to a balancing service, use the formula in
to have
them balanced to the G2.5 specification, for the maximum spindle rpm.
To find the maximum safe RPM for a known unbalance amount, use the formula
in
.
Balance the Entire Assembly
1. Although the cutting tool is not usually a problem in balancing, due to its small mass
and typical symmetric shape makes balance almost inherent. To ensure cutter
balance use high quality cutting tools with flutes, insert pockets, etc. equidistant
from center. Do NOT use cutters with flats on the shank.
2. Balance the entire tool assembly to avoid “stacking” tolerances from individual
components.
