• The major structural component is Meehanite cast iron, which is heat treated to relieve stress, thereby assuring maximum rigidity and accuracy.• Triangulate wide-distance base incorporates a durable ribbed box design for maximum structural loading. • All castings are reinforced with heavy ribs to resist flex and damp vibrations.

• Ballscrews and Linear guideways are provided by world’s top manufacturers. Their premium quality is the only way to achieve high accuracy and longevity. • Pre-tensioned ballscrews eliminate thermal expansion and ensure high working accuracy.

Direct-coupled Axes MotorsDirect-mounted servo motors improve positioning accuracy and provide better contouring and threading.

High Precision Linear GuidewaysMM series uses four-row linear recirculating ball bearing and guideway assemblies for all axes. They provide high load carrying capcity and rigidity with high running and positional accuracy as well as low friction.

Recirculation Ball GuidewaysThe recirculation ball guideways for each axis are preloaded to provide zero clearance between the moving surfaces. This increases rigidity in all directions while providing higher accuracy and reliability.

All structural components and completed machine frame are optimized using finite element analysis and demonstrated by ANSYS Mechanical system.

Spindle Tool Management•Spindle Dynamic Balancing

Taiwan’s Leading Machine Builder www.buffalo.com.tw5 6

The on line dynamic balancing instrument calibrates the spindle displacement, speed, and acceleration of the full speed range.

The fast, simple and long-life automatic tool changer provides stable and reliable tool change.• The innovative cam driven mechanism gives the unique ATC(opt.). The bi-directional tool selection is achieved by PLC software programming.• The carousel type ATC is provided as standard, while side-mounted type ATCs are available for selection.• For MM-400/430, 16 tools carousel type ATC is standard, 24 tools arm type is optional.• For MM-800/1000/1300/1500, 20 tools carousel type ATC is standard, 24 tools arm type is optional, 30 tools arm type is available for MM-1000/1300/1500.

•High Capacity Cartridge Spindle

Radial thrust capacity is improved by preloaded angular-contact bearings and large space between front bearings. Cartridge spindle is designed for easy maintenance.

•One-piece Design HeadstockOffers high stability and capacity for heavy duty cutting.

•Spindle Temperature TracingEach spindle is well tested before it is assembled on machine. 2 hours temperature running trace is recorded to confirm the thermal expansion stability.

20 Bar or 70 Bar Coolant Through Spindle

Auxiliary Coolant Filter

Coolant through spindle uses high pressure pump to supply coolant through tool, cooling the cutting edge directly. This clears chips during deep-hole drilling and tapping, increases tool life and allows higher cutting speeds. Two systems are available, one provides individual CTS tank with 600L big capacity equipped with 20 bar or 70 bar high pressure pump, the other provides 20 bar high pressure pump built-in with machine major coolant tank which requires less floor space. Both systems include the auxiliary coolant filter.

Individual CTS tank is supplied with a re-usable 25-micron iron filter. Built-in system provides 40-micron filter. Both filters take away contamination and particles from the coolant before coolant is recycled through the coolant pump.
