3" Spindle Bore on 17", 18" Swing Lathe
High Speed Precision Lathe — Models 1740G, 1760G, 1880G
These precision lathes comes with 3" spindle through hole for handle wide variety of workpieces. The machine base is made from one-piece premium Meehanite casting for maximum rigidity.
Ergonomics. Attention to Details
- The gear handles on headstock are built with locking detents to prevent the handles from being knocked out of place accidentally or under heavy cutting conditions.
- Repositioning of handles is done by pulling the spring-loaded handle back and then shifting. You will not find a lathe with more positive shifting lever.
- Selection of gears at the gearbox is done by a gear seilection rotary-knob that results in less movement of the gears compare with the back-and-forth shifting lever. Less movement of the gears means less wear and greater accuracy.
Quality components to ensure high precision and long service life
- The spindle support consists of 3 high precision bearings: 2 precision tapered roller bearings and one ball bearing. Using high quality machine tool-grade bearings ensures accuracy and rigidity.
- For maximum stability and minimum distortion, the entire base of the machine is made out of one-piece casting. The casting undergoes the Meehanite process to ensure high tensile strength with excellent vibration dampening characteristics.
- Bedways are induction hardened and precision ground for durability.
- Headstock gears are made out of chrome-molybdenum alloy steel that have been hardened and precision ground for maximum wear resistance.
Convenient Operation
- The universal gearbox design allows easy selection of inch and metric threading without changing individual gears outside the headstock. Simply turn the lever to the assigned position on the headstock.
- The gapped bed design allows extra large workpiece to be chucked at the spindle when the gap is removed.
- The lathe is equipped with a jog button on the headstock that allows small movement of the spindle to aid gear engagement.
- One-shot lubrication system is installed in the apron to direct lubrication oil to all the sliding surfaces.
- Cone clutch overload device in apron to ensure safety when operating.
- High-capacity coolant system offers ample coolant output.
