SHARP LMV-42

Features and Benefits

•  Backlash Eliminator By Double Nut Design replaces the older design that squeezes a split nut to get rid of backlash. Sharp is the first one to use a double nut design that keeps the feed screw in contact with a pair of bronze nuts. Using a custom tool supplied with the mill, the feed nuts are adjusted to control backlash and held tight with a retaining nut and locking ring.
•  The New Patented Knuckled-Head Design prevents the head from slipping. The Sharp mills have a knuckle which uses 6 bolts, 3 each side, fitted into circular T-slots with matching nuts securing them from the outside. It locks the head in place for better accuracy and performance than the old design using only 3 bolts to squeeze the casting to hold the head without the T-slots. (Patent No. 5044054)
•  Roller Bearing Support at the bottom of the motor shaft ensures proper loading, support and alignment of the spindle. It also prevents the distortion of the belts due to tension from long years of milling operation 
•  Easy Access Lubricating Shaft is designed with an oil channel in the center that is fed by a grease fitting at the lower end for longer motor shaft life. (Patent No. 2848)
•  Thrust Bearings mounted at the end of the table and saddle pre-load the feed screw, eliminating end play for precisely controlled lateral movements.
