ITEM: 47" x 65" Double Column Surface Grinder
MAKE: SHARP®
MODEL: SHDC-4765
Product Features
Extra Length Table & Bed Ways - the table ways are made 70% longer than the length of the working surface to prevent distortion and deflection. The length of the bed ways are twice the table ways. This design ensures against overhang of the table working surface
All longitudinal and crossfeed ways are hand-scraped and Turcite coated for high wear resistance and super smooth table movement
High precision spindles are supported by multiple anti-friction bearings, which are adjusted both radially and axially, and are permanently sealed with high quality grease
Runout of taper nose is less than 0.0001" T.I.R. The spindle and motor assembly is dynamically balanced to reduce vibration
The patented design of the crossfeed motor uses a solid state relay and requires little or no maintenance during the life of the machine
The mechinical directional valve is designed to prevent any table reversal shock
A special hydraulic system is used, which is a free-standing unit isolated from the grinder. The heat from the hydraulic oil does not affect grinder performance. Any vibration from the hydraulic pump is isolated from the grinder. A mechanical directional valve provides super smooth table movement with no table reversal shock. Cartridge type oil filters are used, making the oil cylinder and directional valve virtually maintenance-free, for a full five years. Twin single-action hydraulic cylinders and piston rods make table motions rigid and stable. Table distortion is nonexistent
