CONSTRUCTION

 

* BED, CROSS SLIDE AND SADDLE:

The bed, cross slide, and saddle are composed of Meehanite cast iron, which includes very high dampening characteristics. Heavily ribbed castings provide superior dampening decreasing vibration and harmonics providing aggressive turning ability.  The bed casting and saddle are stress relieved to ensure machine geometry is maintained. Spacing of the solid box bed ways create optimal support for the saddle in full travel. The gap (12.75") allows larger turning near the spindle. The "T" slotted cross slide is fully ground and hardened and allows easy mounting of custom tooling. 

 

* WAY SURFACES:

The X& Z-axis way surfaces are hardened and ground with turcite. The square box ways on the Z axis provide added rigidity and strength over a conventional "V" way. Additionally the Z axis ways are widely spaced (405 mm) increasing the stability of the bed and slide providing superior cutting performance. The way surfaces on both axes utilize gibs with easy adjustment to maximize rigidity and maintain geometry throughout the life of the machine tool.

 

* SPINDLE AND HEADSTOCK:

The fully balanced spindle is driven using a 24/15 HP (18/11 kw) 2 Speed Delta/WYE closed loop full regen AC servo motor. Heavy exterior ribbing on the headstock allows for added rigidity and increased surface area for heat transfer. The spindle is directly driven eliminating gears, oil pumps, vibration, and noise. Five high precision, large diameter permanently greased angular ball bearings support the spindle allowing for heavy work pieces. CSS function is standard promoting longer tooling life and improved part finish.

 

* 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 to achieve high rapid traverse rates and thrust. The Z axis ball screw is directly driven using AC servo type motors minimizing backlash and vibration. The 5 mm (X) and 10 mm (Z) pitch ball screws provide a high level of accuracy while maintaining adequate thrust.

 

* AUTOMATIC TURRET:

An 8 position automatic turret provides quick, reliable tool changes. Turning holders utilize 1" square shank tooling and boring bar holders can accommodate 1.5". The bi-directional turret comes standard with 1 boring bar holder and 1 axial tool holder. Additional holders are available and are interchangeable from station to station.

 

* 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.

 

* TAILSTOCK:

The design of the interface free tailstock allows for full cutting along the Z axis travel. The oversized tailstock is ideal for supporting heavy work pieces. The tailstock is easily positioned using a carriage connection coupler. The quill can be moved manually up to 6". A MT#5 dead center is provided with the tailstock.

 

* COOLANT SYSTEM:

A high volume coolant pump (3/4HP) delivers coolant to the coolant nozzle(s) on each turret station. The 50 gallon coolant tank is separate from the machine bed allowing for quick and easy maintenance. The chip drawer rests above the coolant tank filtering chips from reaching the coolant tank and pump. The coolant tank and chip drawer are easily removed from the rear of the machine to allow for chip removal.

 

* 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.
