Machine body structure with advanced castings of resin sand stress relieving. 2. Adopting precision CAD design and high precision frame structure. 3. X, Y axle movement surface with "TURCITE" and ball screw. 4. X, Y axles are made up V-shape and plane structure, ensuring the precision life of mechanical. 5. Adopting Japan SANYO DC servo motor, linear bearing and high strength and precision of integral castings. 6. Using high frequency induction hardening heating treatment. 7. The table which is precision grinded work table. 8. Using centrifugal high pressure oil pump of WALRUS and 10u filter system. 9. The castings are stress relieving cast iron. 10. The desktop uses high frequency quenching. 11. X, Y axles adopts the screw nuts of "model steel "which is produced by Taiwan.That may install ball screw optionally. 12. with functions of large area process and deep holes process. 13. X, Y axles adopt imported or the same level of ball screw. 14. Import accessories including electrode tip, automatic fire extinguisher, lamps, hand pull pump, page switch, gasket and centimeter bring up competitive machine tools.       II.               Machine precision (according to the standard GB5291-85): mm   Item Result Flatness of the working table 0.025 Straightness of vertical when the working table moves X: 0.02 Y: 0.02 Straightness of horizontal when the working  table moves X: 0.01/300 Y: 0.01/300 Parallelism of the working table to motion of the working table X: 0.02/300 Y: 0.02/300 Perpendicularity of transverse motion of the  working table to lengthways motion of the working table 0.015/300 Perpendicularity of assistant motion of  Z-axis to the working table 0.02/100 Straightness degree of motion of  main axis 0.02/300 Perpendicularity of motion of main axis to the  working table 0.01/100 Torsion of motion of principal axis 0.01 Parallelism of linked plane of main axis to the working table 0.01/100 Side rigidity of main axis 0.01 Torsional rigidity of main axis 0.01
