CONSTRUCTION

 * BASE, COLUMN AND SADDLE:

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. 

 * WAY SURFACES:

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.

 * SPINDLE:

The 8000 rpm spindle or optional 15,000 rpm cartridge style spindle is standard CT40. The permanently greased spindle bearings require no maintenance. The five 60 mm spindle bearings provide superior rigidity. The 15,000 rpm spindle includes ceramic bearings to help prevent thermal growth. The 8000 rpm and 15,000 rpm spindle is driven by a 18/12HP (13/9 kW) AC servo motor. Rigid tapping is standard. Spindle air purge keeps the spindle bearings free of foreign contamination.

 * BALL SCREWS AND AXIS DRIVES:

Each axis is driven using a high precision, fully ground ball screw. Each ball screw is 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.

 * OPTIONAL AUTOMATIC TOOL CHANGER:

The 24 pocket carousel ATC provides reliable tool changes.

 * LUBRICATION:

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.

 * REMOVABLE TABLE CHIP GUARD:

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.

 * EDIT KEY:

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.
