Trunnion Table
A Trunnion table that allows four- and five-axis programming is standard equipment on
VM10U machining centers. The maximum allowable diameter for a workpiece on the
rotary axis (C-axis) is 610 mm (24 inches). The clamping system uses hydraulic pressure
to regulate flow of oil to the system. The system’s hydraulic pressure is set at 35 Bar
during factory installation.
During the execution of a part program, the Trunnion table is capable of rotating 360
° in
the C-axis and tilting in the A-axis -30
° to +110°. The table below lists the maximum
allowable weight of a workpiece to be machined on the Trunnion table, distributed evenly
on the table surface.

Pneumatic Clamping System
The VM10U machining centers have a pneumatic system for operating the clamping
system for the A and C axes. The clamping system uses pneumatic pressure to regulate
the flow of air to the system. Refer to Pneumatic System, on page 3 - 22 for details.
Disassembling the Trunnion table or any component of the table may
cause irreparable damage and void your Hurco warranty. Contact a
Hurco-certified Service Engineer to service the Trunnion table.

Large or irregularly-shaped workpieces may become unbalanced
during table rotation. You may need to reset the machining center’s
parameters, reduce the speed, acceleration, or deceleration of the
machining center, or insert anti-tearing joints on the Trunnion table
to ensure large or irregularly-shaped workpieces do not damage the
machining center or rotary table.
