2.2 CAPACITY (DIAMETER)
2.2.1 Barstock Straightness Specifications and Performance
For optimum rotational performance speeds, bar stock straightness needs to be .020” per side,
per 3.25 feet, non accumulative. Bar stock out of this tolerance will not run at optimum RPM.
Other factors such as material type (brass, copper, bronze and other malleable materials),
clamping efficiency of the machine workholding, and alignment of the bar feed, oil type, bar
preparation and spindle liners will affect optimum RPM capability of the system.

Unit : mm
GT 326-E is available for loading bar stock diameter from 3 to 20 mm
(26 mm with bar prep.).
However, for optimum machining performance, the gap between bar
stock and the guiding channel should be kept around 1mm. The bigger
the gap the more chances of vibrations especially with bent bar stock.
Each guiding channel has a range of 10mm above the bar diameter.
