Precision 618 & 818 Series Manual Surface Grinders-1

Clausing Precision 618 & 818 Series Surface Grinders G Manual Surface Grinders G Longitudinal Hydraulics and Motorized Crossfeed Surface Grinders (2A Models) G Longitudinal Hydraulics, Motorized Crossfeed and Motorized Rapid Up/Down Surface Grinders (3A Models) Model CSG3A818 shown with optional dresser and coolant/dust system Outstanding Features... I High Precision Cartridge Spindle High precision cartridge type spindle is supported by 2 preloaded precision angular contact ball bearings & one NN type roller bearing and driven by V3 class motor that allows highly accurate grinding performance. (CSG618/818 series driven by 2HP motor). I Anti-wear Guide Ways The saddle rests on precision hand-scraped double V ways & the table rests on precision hand-scraped V & flat ways which are coated with ‘TURCITE-B’. These guide ways are equipped with auto lubrication to resist wear for lasting accuracy & dampening. CSG618/818 hand feed grinders have ballways between table and saddle. I Rigid Cast Construction Machines are constructed of high grade cast iron with heavy walls & reinforced ribs to provide excellent rigidity and dampening. I Enlarged Column & Base Enlarged column & base create high stability & rigidity. The maximum height is 18" (460mm) from table surface to the center line of spindle. I Auto Lube System Automatic lubrication system is supplied as standard to ensure sufficient lubrication to lead-screws & guideways for greater longevity. I Timing Belt Table Drive Handfeed models (CSG618/818 only) use a timing belt for the table drive which has enclosed high tensile steel cores that ensure more smooth table movement and longevity. The table handwheel can be indexed to 9 different positions, without backlash, for more convenient operation. I Longitudinal & Cross Drive For all models, except CSG618 & 818 handfeed, the longitudinal movement is driven by a hydraulic system; 0n 2A and 3A series, the cross movement is driven by motor for more accurate increment feeding.
