Customer benefits
 Unsurpassed
spindle versatility and wide power range. With the power
range available in R.T. Gilman grinding spindles, you can
use the same spindle for several different operations,
saving time in machine set-up during changeovers.
High speed
The spindle ndm (speed per diameter) is very high,
which means that the ratio of the bearing diameter
versus the speed gives the system a very high stiffness
compared to other spindles.
Easy installation
R.T. Gilman spindle systems can be easily used to upgrade a machine with a traditional belt driven spindle or simply to substitute another integrally motorized spindle. In fact, the spindle is compatible with all of the most popular lubrication units, and it does not require any specialized treatment
for the motor coolant (temperature control or type of media).
Thermal stability
For precision spindle applications, the system's thermal stability is of top priority. In fact, the elongation of the spindle nose resulting from thermal growth is small enough not to compromise the quality of an operation where the axial position of the wheel must be within tolerance (e.g. groove of the bearings).
Low Vibrations
All the rotating parts of the spindle are balanced to G04 grade, and in order to assure that spindle vibration is as low as possible, all components are dynamically balanced and then verified after final assembly.
High stiffness
R.T. Gilman’s High Precision Bearing design configurations, proven in hundreds of applications, provide for a very stiff spindle both in static and in dynamic modes. On each spindle model an accurate dynamic analysis of the harmonic frequencies is done; each spindle's natural vibration frequencies are designed to occur far from the working speed range.
Easy substitution
Change-out with similar R.T. Gilman models is extremely fast: the converter drive "recognizes" the spindle from a special code in the connector, and the operator does not have to make any adjustment.
Long service life
The spindles are designed for a long service life: the construction itself is robust, and because all the parts are standardized, you can repair the spindle repeatedly without affecting quality.
