GENERAL CHARACTERISTICS:
1. High-precision cartridge wheel shaft: The high-precision cartridge-type spindle is supported by two preloaded precision angular contact ball bearings and one NN-type roller bearing, and driven by a V3-class motor, enabling high-precision grinding performance. (The 618/818 series are driven by a 2.0HP motor.)
2. High wear resistance guide surfaces: The saddle rests on precision hand-scraped double V-shaped tracks, and the table rests on precision hand-scraped V-shaped tracks and flat tracks coated with “TURCITE-B”. These guides are equipped with automatic lubrication to resist wear, as well as long-lasting precision and damping.
3. High rigid frame construction: The machines are cast with high-quality cast iron with heavy walls and reinforced ribs to provide excellent rigidity and damping.
4. Enlarged Column and Base: The enlarged column and base create high stability and rigidity. The column height is increased to 18" (460 mm) from the table surface to the spindle centerline.
5. Automatic lubrication system: An automatic lubrication system is applied as standard to ensure sufficient lubrication at the lead screws and guideways for greater longevity.
6. Longitudinal and transverse drive: For all models, except the manual feed 618 and 818, the longitudinal movement is driven by the hydraulic system; for the 2A, 3A, ASD series, the transverse movement is driven by the motor for more precise incremental feeding.
