VM Series Maintenance and Safety Manual 704-0212-209 Machine Components 1- 9
VM10G Spindle
The VM10G is equipped with a motorized spindle that uses a spindle oil chiller to maintain
the temperature of the spindle during machining operations. The motorized spindle on
the VM10G machine rotates in a clockwise direction (while looking down on the spindle
from above).
VM10G Tool Holder
To ensure that the spindle operates correctly, the tool holder used in the VM1G ATC must
be properly balanced.
Table 1–8. Required Tool Holder Balance for VM10G Machine
The status of the tool holder is displayed in the Machine Diagnostics screen and is either
Tool Clamp, Tool Unclamp, or Clamp No Tool.
• Tool Clamp—the tool is securely inserted in the tool holder and the spindle
will operate.
• Tool Unclamp—there is no tool in the spindle. The spindle will only operate
under Tool Unclamp status during a tool change. A tool does not have to be in
the spindle during machine warm-up; however, the maximum speed at which
the spindle can run without a tool is 5000 RPM.
• Clamp No Tool—the tool is not properly inserted in the spindle. The spindle
will not operate under Clamp No Tool status during Manual Spindle On, Auto,
or Manual machine modes.
Because the spindle only rotates in a clockwise direction, do not use
tap operations or counter-clockwise spindle direction for programs
that will be run on a VM10G machining center.
Specification 20,000 RPM Spindle 30,000 RPM Spindle
Balance for Tool Holder 2.5G @ 30,000 RPM 2.5G @ 30,000 RPM
Failure to meet spindle warm-up, spindle run-in, or tool holder
balance requirements may affect machine warranty, and may cause
premature spindle failure, excessive spindle vibration, surface finish
irregularities, and other performance problems.
A Clamp No Tool status error message indicates that the tool is not
fully inserted in the tool holder and may fly out of the holder during
machine operation.
