mounting 3 jaw chuck rotary table supplier

6" PRECISION 3 slot ROTARY TABLE /HORIZONTAL&VERTICALwith 6" 3-jaw self-centering chuck top&bottom reversible jaws, front mounting. All bolts and T-nuts to  mount the chuck  included.

1. The screws securing the chuck to the plate are too long, they need to be shortened about 1/4" to keep from bottoming out in tapped blind holes in the chuck.

2. The "T" nuts holding the plate to the table are poor quality. The flange portion of the nuts are too tall so they interfere with the locking tabs on the table when you attempt to rotate the table.

3. And the worst problem is the raised area on the adapter plate which centers the chuck to the table is a sloppy fit, about .017" allowable movement.

Once you shorten the attaching bolts, machine the "T" nuts down about .100" and bore out the locating boss and re-machine it to an appropriate fit in the rotary table, it works pretty well.

A serialized set of jaws are then finished, ground, and lapped on their designated chuck body which will be the same chuck body on the final assembly to achieve a greater accuracy

Before assembling the jaw to its designated chuck body, the jaw"s finish machining are performed on a closed tolerance state of the art CNC machine from Japan

Rotary mounted three-jaw manual chuck with high concentricity. For internal and external clamping of rotationally symmetrical parts. With Ø2 x 7 mm deep holes and 2 sets of pins of different lengths for elevating parts for access from all sides. Available with an SWA 39 quick-change adapter or base plate.

Three-jaw chucks are mainly used for clamping cylindrical or ring-shaped parts at higher clamping forces. Due to the radial clamping of rim-type chucks, damage to the rotary table can occur at higher forces. Due to the central clamping via a kind of knurled nut, which is inserted into the inner square of the chuck, no radial forces occur. This means that the components can be clamped exactly with the required clamping force. With interchangeable jaws you can easily adapt the lathe chuck to your requirements.

This high quality piece makes a great addition to your rotary table! It includes a back plate for easy mounting to your 8" 4 slot rotary table. The chuck is high grade and precise and it features reversible jaws for inside or outside grip on parts. Super quality at a super price!
