 The base, column and bridge are constructed with reinforced steel. Extra webbing provides additional support for the axis. The columns on the machine are extremely wide providing full support for the bridge. The bridge design provides added rigidity and support to the tool. All critical components are pinned to ensure that machine geometry is maintained.


The axes are standard with heavy-duty 45 mm linear roller guide ways. Roller type guide ways have 44% more contact than standard linear ways. The guide ways are widely spaced to minimize table pitch and deformation. The guide ways are placed against shoulders to maximize rigidity and geometry. Six linear roller bearings are standard for the Z and Y axis.


The 10,000 rpm spindle or optional 15,000 rpm cartridge style spindle is standard with a Big Plus® dual contact technology. Taper and face contact proves to provide the most rigidity allowing for decreased tool deflection and cycle times. The permanently greased spindle bearings require no maintenance. The 10,000 rpm spindle is driven by a 2 speed 24/15HP (18/11 kW) In-line AC servo motor. In-line motor designs reduce vibration and heat improving part finishes and tolerances. The four 70mm ceramic spindle bearings help minimize thermal growth on the 15,000 rpm spindle. Rigid tapping is standard. A high torque spindle option is available that limits the standard spindle rpm to 8000 but increases the spindle torque to 310 ft-lb.


Each axis is driven using a high precision, fully ground ball screw. The X and Y axes ball screws are double anchored to allow exceptionally fast feedrates. The X axis ball screw utilizes a rotating nut design that maintains high rapid traverse rates while reducing heat and vibration typical of extended length ball screws.


The 24 pocket carousel ATC provides reliable tool changes. Remote tool changer control is included.


A dedicated flood pump provides high volume coolant to the machine tool. The 100 gallon coolant tank provides adequate capacity for any application. Dual chip augers are included, that discharge into chip drawers. An optional chip conveyor is also available that is used in conjunction with the dual chip augers.


The machine enclosure is made of heavy duty sheet metal to contain the chips and coolant. The removable side doors allow direct access to the inside of the machine. Dual augers remove chips effectively from the machine into chip drawers, or an optional conveyor is available in lieu of the chip drawers.


Automatic lubrication is provided to the linear guide ways and ball screws via way oil. Oil is delivered by metered valves, which precisely control the volume. A low-level alarm on the CNC warns the user preventing possible damage to the guide ways and ball screws.


Thermal growth of the spindle is reduced by using a refrigeration system that circulates cooled oil around the spindle increasing the accuracy and promoting longer spindle life.


The edit key enables protection of programs as well as parameters of the 8200-B CNC control. Removal of the key limits a user from loading programs and parameters such as work coordinates and tool offsets. With the edit key in the off position the data in the CNC control is available for editing.
