This package provides a complete rotary table and indexing solution. Unique to LittleMachineShop.com the set is comprised of our 4″ horizontal/vertical rotary table, Dividing Plate Set, and Tailstock for 4″ Rotary Table. Save by buying all three as a set!
The rotary table is perfect for indexing, circular cutting, angle setting, boring, and spot facing operations on a milling machine. Made of precision machined cast iron, this table features a 2 Morse taper center hole and comes with lock down clamps. It is graduated with a 360 degree scale, making it easy to read and use.
The table comes with an adapter to mount a 3″ (3 or 4-Jaw) lathe chuck. The table is 2.87″ high in horizontal position and has a centerline of 2.68″ above the table in vertical position. The body of the table is 5″ by 5.5″ and has a worm ratio of 72 to 1. The clamping surface has a parallelism to base of 0.0008″, squareness of clamping surface to angle face of 0.0012″, and squareness of clamping surface to center slot of 0.0012″. Concentricity of center bore is 0.0008″ TIP.
The Mini Mill Dividing Plate, a handy tool for precise milling and dividing. This plate dividing plate fits a 4″ precision rotary table. It consists of one plate with two sets of holes. One circle has 15 holes, and the other has 28 holes. This lets you divide a circle into 1/3 degree increments.
You can divide a circle into the following number of divisions 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 24, 27, 28, 30, 32, 36, 40, 42, 45, 48, 54, 56, 60, 72, 84, 90, 96, 108, 120, 135,144, 180, 216, 270, 288, 360, 540, 1080.
The tailstock is height adjustable from 68 to 69 mm center height. On mini mills, most indexing is done using a rotary table. The addition of dividing plates makes indexing easier. When working with relatively long work pieces, a tailstock can be used to support the end of the work piece. In many cases, a lathe chuck is mounted on the rotary table to hold the work piece.
