2008 SHARP Model 2280B Precision Engine Lathe 22'/31" X 80" The “B” models are equipped with D1-11 camlock spindle, 4.5” spindle bore. The spindle is mounted on 2 precision tapered roller bearings and one ball bearing. This triple bearing support system ensure accuracy and rigidity at all times. Handles that are used for engaging gears are built with locking pins to prevent the handles from being knocked out of place accidentally or under heavy cutting circumstances. Pulling the spring-loaded handle back and then shift does repositioning of handles. The universal gearbox design allows easy selection of inch and metric threading by just turning the lever to the assigned position instead of changing individual gears outside the headstock. A rotational style lever that results in less movement of the gears compare with the back-and-forth shifting style lever does selection of gears at the gearbox. Less movement of the gears means less wear and greater accuracy. The gapped bed design allows extra large work piece to be chucked at the spindle when the gap is taken out. Bed ways are induction hardened and ground for durability. Headstock gears are hardened and ground, made out of Chrom-Moly alloy steel for maximum wear. The headstock is equipped with a job button that allows inching movement of the spindle for easy engagement of gears. One shot lube system is installed in the apron to direct lube oil to all the sliding surfaces.
