The base, column, and saddle are composed of Meehanite cast iron, which includes very high dampening characteristics. The one piece base casting and column are stress relieved to ensure machine geometry is maintained throughout the life. Spacing of the solid box ways ensure optimal support for the table and saddle in full travel of each axis. Heavily ribbed castings provide superior dampening for high speed machining and aggressive milling. The mating surface of the base and column are hand scraped to optimize fit and machine geometry. The 54"x16" machine table is fully ground and hardened. 


The Y & Z-axis are hardened and ground square box ways with turcite on all axes. The ways are spaced to eliminate table pitch and deformation. The way surfaces on all three axes utilize gibs with easy adjustment to maximize rigidity and maintain geometry throughout the life of the machine tool.



The oversized 4.125" quill comes standard with CT40. The quill has 6" of travel for manual operations. The spindle is belt driven using an inverter control AC spindle motor. The spindle rpm is fully programmable using the CNC control. An 8:1 manually shifted back gear allows for applications requiring high torque. Tools are secured in the spindle using a drawbar with a power drawbar. The head is capable of tilting ±45 for additional flexibility. A quill mounted scale allows feedback to the CNC to update tool length offsets.  Retention knobs are not required.


Each axis is driven using a high precision, fully ground ball screw. Axis ball screws are supported on each end using angular contact thrust bearings and are perfectly centered between the way surfaces. The axis ball screws are belt driven with AC servo type drive motors.


Automatic lubrication is provided to the way surfaces and ball screws with oil to eliminate wear. Way oil is delivered by metered valves, which precisely control the volume. A low oil-level alarm warns the user preventing possible damage to the way surfaces and ball screws.


The table chip guard is conveniently designed to allow the operator to easily remove the guarding. This convenience offers the best solution to chip and coolant containment in normal working conditions, and when an oversized work piece needs machining the guarding is easily removed allowing oversized parts to hang over the table.


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.
