3 S P / S P AND FORM GRINDER Parallelism of Table Surface to Table Cross Transverse INSPECTION Runout of Wheel Spindle Conical Surface 2 Attach the base of a test indicator to the wheel head. Touch the stylus of the indicator to the table surface. Traverse the table in and out, The indicator variation shall be within "(0.0015mm). Apply a test indicator to the rear, middle and front points of conical surface of the wheel spindle, and rotate the wheel spindle, the variation shall be under "(0.0015mm). Parallelism of Table Surface to Table Longitudinal Movement Attach the base of test indicator the wheel head. Touch the stylus of the indicator to the table surface. Move the table left to right and reverse. The indicator variation shall be within "(0.002mm). Spindle Dynamic Balancing Test Before delivery, the spindle of each machine has to be calibrated by a portable precision dynamic vibration measuring equipment. The final amplitude of spindle vibration shall be under "/s(0.015mm/s) Parallelism and Square of Wheel Spindle Centerline to Table Surface Place a cylinder gauge on the table, swing the test indicator which is fixed on the wheel spindle, and obtain the readings of the indicator when table is at its right, middle and left positions. The parallelism is /8 (0.004/200mm )or less and the square is under /8 (0.004/ 200mm). Steel Ball Sifting Steel balls used in longitudinal movement are all heat treated and sieved by automatic machine which assures the diameter tolerance of steel balls in the same machine is under "(0.002mm) Flatness of Ground Workpiece Due to excellent rigidity and stability of machine structure, the flatness tolerance of ground workpieces shall be "(0.002mm) or better.

4 6 3 MACHINE CONSTRUCTION 2HP Low Vibration Spindle Motor By using a 2HP class V3 low vibration spindle motor, both fine grinding and rough grinding can be performed to obtain the best grinding result. ASSEMBLY High Precision Spindle Assembly Room All spindles are assembled by skillful and experienced technicians following exact assembly procedures in a temperature controlled clean room. High Precision Cartridge Type Sp Spindle is supported by 4 pieces of class 7(P4) super precision angular contact ball bearings which have been accurately measured, selected and preloaded, and then assembled in a temperature controlled room to ensure better grinding accuracy and surface finish. The labyrinth seal type structure is designed to offer better water-resistance, thus enhancing longevity of spindle bearings. Elevating M The microfeed (1µ locks the hand Operation of t Spindle Assembly Spindle bearings and spindle cartridge sleeve are preheated at the proper stage of installation to a s s u re n o u n d u e forces applied to spindle bearings. Spindle Bearing Grease Sealing All spindle bearings are sealed with high grade grease to minimize thermal expansion for longer service life of bearings. Spindle Bearing Spacer Measurement In order to assure the best assembly accuracy, the flatness tolerance of both inner and outer spacers must be within "(0.001mm). Spindle Temperature Rising Test To assure spindle temperature rise does not exceed 10 o C, spindle is tested under a no load condition for 8 hours minimum. During the test, the spindle is running throughout its permissible speeds and is being continuously monitored by a thermo recorded graphic.
