| STANDARD FEATURES | |
| • | Handfeed operation model |
| • | All castings are made of high grade Meehanite® cast iron that is stress relieved through annealing to eliminate internal stress, with stiffness and stability of the castings, the machine is suitable for both precision surface grinding and form grinding |
| • |
2.2 HP Class V3 grade low vibration spindle motor, both fine grinding and rough grinding can be performed to obtain the best grinding result |
| • | High precision cartridge type spindle is supported by four pieces of class 7 P4 super precision angular contact grease sealed ball bearings, suitable for longer service life and heavy duty grinding |
| • | Machine base slideways are laminated with Turcite B and precisely hand scraped, the low friction slideways incorporated with automatic forced lubrication system ensures high accuracy and longer way life |
| • | Hardened and ground table guideways with steel ball bearings providing smooth, accurate and efficient table movement, the double V crossfeed guideways designed |
| • | The table is driven by a continuous loop wire reinforced cog timing belt to ensure slip free and smooth transmission, the life of continuous cog timing belt is three times longer than wire type or reciprocating timing belt type |
| • | The table handwheel can be indexed to a comfortable position to enhance the ease of table traverse |
| • | Table reversing mechanism by using proximity switches for easily set suitable table stroke for each workpiece to save grinding time and obtain higher grinding efficiency |
| • | Automatic forced recirculated type lubrication system provides lube oil to saddle, column ways, cross and elevating leadscrews to minimize the chance of wear due to negligent operation and ensures the machine accuracy and prolongs the life of the machine |
| • | The interlock between electrical cabinet door and power supply to ensure safety operation |
| • | Machine shown with optional accessories |
| • | Voltage requires 220V/440V/3 Phase/60 Hz., prewired 220V |
