Surface Grinder RP 818 SerieAutomatic Surface Grinder

M series are a manual 3-axis version.
H series features hydraulic longitudinal movement with manual vertical and cross axes.
AH series feature auto cross feed, a hydraulic longitudinal, and a manual vertical axis. (Optional AD5 can be added to move this axis fully automatic)
High grade Meehanite cast iron base, column, table, and saddle, multi-ribbed and properly aged.
Table rides on precision V and flat ways (H and AH series. Roller ways for M series). The saddle rests on double-V hand-scraped precision guideways which ride on Turcite B anti-friction bearing material.
Centralized automatic lubrication system to all guideways and lead screws.
Precision cartridge type grinding spindle mounted on highest grade preloaded angular contact ball bearings, sealed for life. Direct drive.
Centralized console control system for all functions, mounted on articulated arm for operator convenience.
Wheel dresser, manual over-the-wheel type.
Chuck, work light, wheel flange & nut, leveling screws & blocks, service tools and tool box, operators manual, wheel balancing stand and arbor.
Complete 3/60/220/440 volt electrics in Nema-type enclosure with disconnect switch.
