Five Face Machining Centre All Models by S. R. Engineering Co

Ballscrew Cooling System

Each axis is driven by a large diameter, high precision ground, pre-loaded and double anchored ballscrew providing high accuracy, fast rapid federates and maximum feed thrust. Models with travel over 3m are equipped with cooling system through ballscrew on X-axis to alleviate thermal expansion, resulting in higher positioning accuracy. Models with travel over 4m possess supporting way for X-axis to solve the problems of overhanging and vibration.

Gear Box of the three axees

Three axes feed mechanism employs gear transmission and precise ballscrew with precision class P4 angular contact ball bearings. Gears, ground in accordance with DIN level 5, provides good transmission efficiency and also gives the advantages of great transmission torque at low speed and excellent dynamic response at high speed

Minimum Spindle Distance

The distance between spindle center to Z-axis slideway surface is 150mm. Spindle center is located at the center of headstock which eases the thermal expansion caused by increased temperature of spindle; therefore, raises the resistance of the body structure when cutting providing higher machining accuracy and stability.

BMC Superior Body Structure

The machine bed, column, spindle head, cross slides and table are all analyzed and optimized by FEM tests. This design assures high stability and rigidity of the machine, thus making it suitable for heavy-duty machining of all kinds of materials.
