Precision Linear Roller Guideways in the Longitudinal (Worktable) slide ensures effortless movement, high repeatable accuracy and long service life. The fine-adjustment mechanism of this roller slide provides for precise setting of Guideways according to requirement.

The Grinding Spindle, which has a Cartridge type design, is assembled on 2 pairs of Angular Contact Bearings, imparting high performance in both ‘Axial’ & ‘Radial’ load applications during Tool Sharpening operations. A taper nose at both the ends provides for quick and accurate mounting of different Wheel Flanges according to different wheel applications. It is a Belt driven unit so as to isolate it from any residual vibrations in the Motor during the entire course of its service life.

An utmost important characteristic is its highly versatile design, which enables the Tools of varied geometries to be sharpened without any hinderance. It includes:
• Worktable swivel to 90 deg.
• Pillar shifting on an area of approximately 480 mm in the rear.
• Pillar swiveling to complete 360 deg. on its Vertical Axis.
• Tilting of Spindle Head to +/- 15 deg. (Optional).
• Shifting of the Spindle block vertically on the Pillar (Optional) in addition to the vertical movement by leadscrew.
• Movement of the Cartridge Spindle individually from the Spindle Block by about 40mm.

Combined with a rugged Steel Cabinet with storage compartments, a wide range of user friendly attachments for re-grinding / manufacturing of standard or special tools, and quality parameters within IS 3080 requirements, APAR T-480 is the PERFECT solution to the mentainence of your varied tools.
