High Productivity
• Maximum 2500 to 3000mm turning capacity
• Maximum 25tons load capable table
• Elevating cross rail 1000mm travel
• Full controlled C-axis and rotary spindle (Milling, Drill, Tap): M type
• Automatic tool changing system (2 axis : 12EA, 3 axis : 16EA)
• APC device, hydraulic chuck, auto index chuck etc, equipment for high efficiency. High Reliability · High Precision
• Heavy duty, wide guide ways of box type (Bed, Column, Cross-rail, Saddle)
• Massive one-piece cast iron bed, column, saddle, and cross-rail
• Extra large 260mm square spheroidal-graphite-iron ram
• Induction-hardened and precise-ground guide ways
• Qualified precision bearings & ball screws
• Full automatic lubrication to all critical areas
• Oil cooling system for table cooling to suppress thermal displacement
Machine Construction The column, cross rail, bed, saddle, and table are constructed of high quality Meehanite cast iron.These main components are densely ribbed, thick walled, and fully stress relieved for long lasting accuracy.
Bed The stress analysis was applied to the bed structure design for maintaining the best condition to support the heavy load and cutting force and to minimize the distortion,deflection and dampen vibration.
Table & Spindle Bearings
• Heavy duty table and large diameter high precision spindle bearings guarantee heavy loads and precise machining.
• Heavy duty 4-jaw independent chuck is standard(max. clamping force4metric tons).hydraulic power chuck and automatic palletchenger system are available.
• The main spindle and drive gears are made of special alloy steel. They are induction hardened, fully stress relieved, and then precision ground for maximum performace.
• The power is transmitted to the table through the automatically shifted two speed gear box which generates enough speed and torque to satisfy wide spectrum of most demanding machining requirement.
• High-accurate table index by C-axis control: 0.001°
• Forced lubrication system provided.Motor & Table Gear A direct connection of drive gear train to the motor minimize the loss of torque.Saddle & Ram
• The 8-ton tool holder clamping force ensures strong and rigid machining. Ram indexing by Quad Holder allows rotating 4 tools directly from RAM without ATC access via 90 degree rotation. The tool change time has been shortened by 75% (260mm).
• The saddle enclosing the ram is one-piece casting to keep the high rigidity.
• 3axis model has milling spindle with high-speed that involves drilling, milling, and tapping.
• Automatic metered lubrication system ensures lasting accuracy.
Elevating Cross Rail
• Vertical positioning of this massive cross rail is hydraulically powered.
• Positioning accuracy is assured by automatically actuated precision pins and 37.4 tons of hydraulic clamping force.
Automatic Tool Changer
• The standard 12 tool capacity(16 tools for M type) automatic tool changer system and a wide variety of available tooling enable uninterrupted fully automatic machining possible.
• This rigidly constructed carousel type tool changer features high speed random indexing and is capable of safely handling tools of up to 100kg(220 pounds).
Guide Ways
• The wide box type guide ways are induction-hardened and precision-ground.
• Mating surfaces of the sliding components are coated with fluroplastic resin and are hand scraped for perfect fit. fully automatic metered lubrication system provided.
Axis Drives
• Each axis is driven by a high precision ballscrew and is powered by a high touque, maintenance free fanuc digital AC servo motor.
• Ballscrews are supported on both ends by high precision bearings.
• The optional X axis linear scale feed back system combined with double anchor pretensioned design assures outstanding machining accuracy and repeatability.
