Lortone Arbors Instructions & Parts Lists

Lortone arbors are used for grinding and polishing. Ideal for lapidary & glass work. Their widely spaced wheel centers are easy to use and can accommodate a variety of grinding/polishing wheels and drums. We use a sturdy, welded steel frame coated with a high quality powder-coat finish for durability and smooth running rubber mounted bearings for quiet operation. Tapped shaft ends make installing spin on polish heads simple. REQUIRES the use of an overhead drip or pump fed coolant system. MOTOR AND WHEELS ARE NOT INCLUDED.

Setting up your machine: Check the parts list to make sure all parts are included. If any parts are missing please contact your dealer or the factory immediately. Note: Unit does not come with a drive motor. It must be purchased separately. Fasten the rubber feet to the bottom corners of the machine and under the motor mount. Place unit on a clean sturdy work table.
