Rigid Machine Structure/Precision Spindles/Slide Table

Economic Series - SPC18/ SPC1810 /SP20

1. Rigid Machine Structure
(1) The machine structure is manufactured from high quality Meeharite cast iron, heat treated and stress relieved before machining.
(2) Sideways are high frequency hardened and precision ground. Maximum material stability for deformation-free and outstanding wear resistance.

2. Precision Spindles
(1) The grinding wheel spindle and the regulating wheel spindle are precision machined from Nickel Chromolybedenum alloy steel (SNCM-220). Also, they are subject to various treatments such as: normalized, tempered and carburized hardening. Then, the spindles are thru sub-zero treated – under zero degrees, precision ground and precision machined.
(2) The inside of spindle is tempered to hardness HRC 25°~30°, while surface hardness reaches over HRC 62. The precision ground spindle is excellent for heavy-duty machining and features powerful torque, long service life, deformation-free and maximum wear resistance.

3. Slide Table
(1) Upper slide swiveling is easy and accurate to adjust for making the machine suitable for infeeding grinding. Also, it allows grinding for a varied diameter fo workpieces. The Upper slide with +5°~-5° swiveling allows taper grinding by using infeed grinding mode.
(2) With thrufeed grinding, the Upper slide provides a surface contact adjustment between the workpiece and grinding wheel. Swiveling adjustment range is +5°~-3°.
(3) Dovetailed slideway on the upper slide features smooth and accurate feeding and is lubricated by a centralized lubricator.
(4) The bottom slide moves on “Λ” shaped and double-wedged ways.The slideways are hardened and precision ground. They feature smooth movement and properly protected to prevent dust from entering. Micrometric feed adjustment unit is 0.001 mm to meet high accuracy requirements for all workpieces.
