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
2-Axis Automatic (X,Y)
High Precision Spindles are supported by multiple anti-friction bearings, which are adjusted both Radially and Axially, and are permanently sealed with a 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 Mechanical directional Valve is designed to prevent any table reversal shock.
2 or 3-axes Auto
10 HP Motor
Spindle Speed 1,720 rpm
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.
