Applications:
1. This large manual rotary table is broadly used on a milling machine to perform operations including indexing, circular cutting, angle setting, boring and spot-facing, etc...A dividing plate can be supplied as an optional accessory to help the operator to conveniently obtain on the workpiece equal divisions in any integer number through 2 to 66, or in any integer number through 67 to 132 which are divisible by 2, 3 or 5;
2. As the worm wheel in this rotary table can be disengaged conveniently, this rotary table can also be used as a precision rotation device for measurement applications where it can set up the part to be measured firmly and rotate it continuously;
Features:
1. High precision and heavy-duty manual rotary table, horizontal mounted;
2. Rigid bases on this rotary table are made of superior grade Meehanite gray iron castings and can maintain long-term stability and accuracy;
3. The worm wheel in this rotary table can be easily disengaged to rotate freely, thus it is very suitable for measurement applications during which it clamps the item to be measured firmly and rotate continuously;
4. The rigid and reliable brake system guarantees a firm clamping for the turntable to ensure it to position the workpiece firmly enough to undertake heavy cutting;
5. The dual-lead worm shaft and worm wheel system provide the best backlash adjustment;
6. High wear-resistant tin-bronze made worm wheel, the hardened and precision ground alloy steel made worm shaft guarantee a long-term stable positioning accuracy for the rotary table;
7. High precision spindle and high precision spindle bearings guarantees the minimum radial run-out and the minimum end run-out of the turntable;
8. Hardened and precision-ground bearing surface of the turntable is wear-resistant and can maintain high flatness accuracy for a long time in operations;
9. This rotary table is designed to accept dividing attachments and various tooling and workholding options.
