6″ ROTARY TABLE TAILSTOCK DIVIDING PLATES LATHE CHUCK & CLAMPING KIT (3906-2316)

6″ Rotary Indexing Fixture Kit for Milling and Repair Work

This 6-inch rotary indexing fixture kit brings together the workholding and positioning components required for circular milling, bolt patterns, angular features and supported between-center setups.

The package includes a horizontal/vertical rotary table, adjustable tailstock, two dividing plates, a 4-inch 4-jaw self-centering chuck, aluminum mounting plate and a 10-piece clamping kit. It provides a coordinated solution for machine shops that do not want to source and match each component separately.

Use it for one-off repairs, prototype components, automotive flanges, mold inserts, maintenance parts and manual secondary operations that would otherwise require time-consuming layouts or multiple fixture changes.

A Complete Workholding Package

Buying a rotary table alone often leaves the machinist searching for a compatible chuck, mounting plate, tailstock, clamps and indexing accessories. This package supplies the essential components together:

• 6″ horizontal/vertical rotary table
• Adjustable tailstock
• Two dividing plates with multiple hole circles
• Indexing crank handle
• Sector, U-washer and three screws
• 4″ 4-jaw self-centering scroll chuck
• Aluminum chuck mounting plate
• Internal and external solid-jaw sets
• Chuck wrench
• 10-piece clamping kit

Built Around Real Workshop Problems

Repair and prototype jobs rarely arrive as convenient rectangular parts. A mechanic may need to reproduce a damaged bolt circle, a mold technician may need to reposition an insert, and a CNC shop may need a manual fixture for a secondary operation that does not justify programming another setup.

This rotary-table package helps solve common workholding and positioning problems:

• Creating evenly positioned holes without repeated manual layout
• Holding round or square components in a centered chuck setup
• Supporting longer workpieces to reduce deflection and chatter
• Positioning parts horizontally or vertically on the milling machine
• Moving rapidly to an approximate angle before making a fine adjustment
• Completing low-volume indexing work without a powered fourth axis
• Reducing compatibility problems caused by separately sourced accessories

Horizontal and Vertical Machining

The rotary table can be mounted horizontally for operations around a vertical axis or vertically when the workpiece must rotate around a horizontal axis.

The low-profile construction helps preserve spindle clearance when the table is mounted horizontally. Controls are positioned for practical access during setup and angular adjustment.

Fast Free Rotation and Fine Angular Adjustment

The worm gear can be disengaged when rapid free rotation is needed. This allows the operator to move the table quickly to an approximate position instead of advancing through the entire angle with the handwheel.

After the worm mechanism is re-engaged, the handwheel and vernier scale provide controlled final positioning. One complete handle rotation moves the table 4°, and the table is graduated through a full 360°.

The 10-second vernier reading supports fine angular settings for jobs that require more control than a basic degree scale provides.

Solid Alloy-Steel Worm and Shaft

The one-piece worm and shaft are hobbed from solid alloy steel. The rotary-table surface is precision ground to support accurate setup and workpiece alignment when the unit is correctly installed and indicated on the milling machine.

For consistent results, approach final positions from the same rotational direction whenever possible. This helps minimize the effect of mechanical backlash during indexed operations.

Dividing Plates for Repetitive Indexing

The two included dividing plates expand the table’s manual indexing capability. The set also includes the crank handle, sector, U-washer and required screws.

Together, the plates provide 33 listed hole circles for calculating a wide range of equal divisions. The achievable divisions depend on the indexing calculation, selected hole circle and rotary-table mechanism.

Adjustable Tailstock for Longer Workpieces

The included tailstock adjusts from 3.2″ to 4.3″ in height. When correctly aligned with the rotary axis, it can support longer or slender components during vertical-table operations.

This additional support is valuable when machining shafts, pins, sleeves and similar parts that may otherwise deflect or vibrate under cutting forces. Tailstock alignment, center preparation and workpiece rigidity should always be verified before machining.

4″ Four-Jaw Self-Centering Chuck

The included 4-inch universal scroll chuck uses four self-centering jaws that move together. This configuration simplifies the setup of compatible round and square workpieces where centered holding is preferred.

The chuck is made from high-grade tool steel and includes:

• One set of solid internal-diameter jaws
• One set of solid external-diameter jaws
• Chuck wrench
• Aluminum mounting plate

Because this is a self-centering scroll chuck, it should not be confused with an independent 4-jaw chuck in which each jaw is adjusted separately. Verify the chuck’s gripping capacity against the intended workpiece before ordering.

10-Piece Hardened Clamping Kit

The clamping-kit components are manufactured from drop-forged steel and are case hardened and heat treated. The kit contains:

• 2 step clamps
• 2 step blocks
• 2 studs
• 2 T-slot nuts
• 2 flanged nuts

These components provide a starting point for securing compatible workpieces and fixtures. Always confirm stud size, T-slot dimensions and required clamping reach before use.

Applications in Automotive Workshops

Automotive and engine-repair workshops can use the rotary fixture for controlled positioning of compatible components such as:

• Flanges and adapter plates
• Pulley and hub bolt patterns
• Custom brackets and mounting plates
• Small drivetrain and steering components
• Repair parts requiring equally spaced holes
• Prototype components for vehicle modifications

Component size, material, chuck capacity and machine load must be verified before machining safety-critical automotive parts.

Applications in Mechanical Repair

Maintenance and repair departments often need to reproduce a discontinued part or modify an existing component without creating a dedicated production fixture. This setup can assist with:

• Pump and motor flanges
• Bearing retainers and collars
• Valve and pipe-interface components
• Fixture plates and machine guards
• Damaged or obsolete replacement parts
• Low-volume plant-maintenance jobs

Applications in Mold and Die Repair

For mold-maintenance work, the table can provide controlled angular access to compatible inserts, retainers and fixture components. Typical uses include:

• Positioning mold inserts for repair machining
• Creating circular or radial hole patterns
• Machining clamp and retaining components
• Producing replacement bushings and collars
• Preparing fixture plates for mold-maintenance operations

It is not a substitute for the machine accuracy, inspection process or specialized equipment required for critical mold surfaces.

Useful for CNC Shops and Secondary Operations

A CNC shop does not always need to occupy a machining center with a simple one-off indexing job. This manual rotary fixture can be used on compatible milling equipment for prototypes, rework, inspection fixtures and secondary operations.

This is a manual rotary table, not a programmable CNC fourth axis. It is intended for hand-operated positioning and indexing rather than simultaneous CNC-controlled rotary machining.

A Capable Package for Serious Hobby Machinists

Home and educational workshops often face the same workholding problems as commercial shops but with less space and fewer dedicated fixtures. This kit combines multiple capabilities in one setup for projects such as small gears, model-engine parts, instrument components, custom fixtures and restoration work.

The dividing plates and tailstock also create room to develop more advanced machining skills without purchasing each accessory individually.

Frequently Asked Questions

Does this package include the chuck and mounting plate?

Yes. It includes a 4″ 4-jaw self-centering scroll chuck, aluminum mounting plate, chuck wrench and separate ID and OD solid-jaw sets.

Can the table be mounted vertically?

Yes. The rotary table is designed for horizontal and vertical use. The adjustable tailstock can support compatible workpieces when the table is used vertically.

Can it create equally spaced hole patterns?

Yes. The graduated table and included dividing plates support calculated angular positioning and equal divisions. The machinist must select the correct plate, hole circle and crank movement for the required pattern.

Is this a CNC fourth axis?

No. This is a manually operated rotary table. It can be useful for manual secondary operations in a CNC workshop, but it is not designed for programmable simultaneous fourth-axis machining.

Why choose a package instead of a rotary table alone?

The package includes the tailstock, chuck, mounting plate, dividing plates and basic clamping components. This reduces the need to identify and purchase several essential accessories separately.

One Setup, More Repair and Indexing Capability

For workshops that regularly encounter short-run repairs, prototype components and jobs that do not fit a standard vise, this 6-inch package provides a more flexible starting point than a rotary table alone.
