Precision-Adjust Rotary Tables


Standard Table	Mounted Horizontally

Heavy Duty Table	Heavy Duty Tilting Table

Turn workpieces 360° for precise alignment during milling, drilling, and grinding. With finely ground worm gears, these tables give you fine control of your workpiece’s alignment to fractions of a degree. The gears also keep the tabletop from moving once your workpiece is in position, even if you bump it or press against it while you machine. Markings on the handle’s dial and the tabletop’s edge tell you how far you’ve moved, so you don’t overshoot your mark. The tabletop and base are ground so flat their surfaces vary less than the thickness of a single sheet of copy paper, so they give you the flattest and squarest possible surface for accurate work. The base also has both keyways and bolt slots to mount these tables in both vertical and horizontal orientations.

Heavy Duty Table—These tables move in smaller increments for finer control than our standard rotary tables. They’re also machined three times flatter, virtually eliminating uneven positioning. Once the table is in position, dual locks prevent even the slightest table rotation. Hardened and oil-immersed gears extend their life, especially in high-demand machining.

Heavy Duty Tilting Table—The same upgraded performance as our heavy duty standard tables but with an adjustable tilt. Tilt these tables between 0° and 90° to cut your workpieces at an angle. Compared to our standard rotary tables, these move in smaller increments for finer control. They’re also machined three times flatter to virtually eliminate uneven positioning. Dual locks prevent even the slightest table rotation after the table is in position. Hardened and oil-immersed gears extend their life, especially in high-demand machining.

Gear Ratio—Gear ratio describes how far the table rotates with every turn of the handle. For example, a 90:1 gear ratio means a 90° turn of the handle rotates the table 1°.

Tailstocks—Support long workpieces to improve stability during indexing and machining.

Precision-Adjust Cross-Slide Rotary Tables


Standard Table	Tilting Table

These tables do it all. They rotate 360° and slide on the X-Y axes to position your work with exact alignment. Cut with trapezoid-shaped Acme threads, the internal X-Y screws minimize backlash and won’t deform. They’re precision ground to ensure accurate cuts every time.

Mount these tables on your milling machine, drill press, or grinder. They reduce the height of your setup by over 30% compared to stacking rotary and milling tables. Balanced to prevent unintentional movement, the crank handles take less effort to turn than hand wheels. With bulbous grips, these handles fit comfortably in your palm. Graduations engraved on the bases of the handle and table help you line up your work in fractions of a degree. Tighten the locking clamp on the side of the table base to keep the table steady as you machine.

Tilting Table—The most versatile tables we offer. They also tilt in 1° increments to any angle between 0° and 90°, so you can machine parts from any direction. Tighten the hex bolts on the side plates to keep the table at your desired tilt.

Gear Ratio—Gear ratio describes how far the table rotates with every turn of the handle. For example, a 90:1 gear ratio means a 90° turn of the handle rotates the table 1°.

Quick-Change Fixture Plates

Snap these magnetic plates in and out of the mounting rail as swappable stages for measuring and inspecting parts. Unlike standard fixture plates that you need to bolt or clamp down, these quickly attach and release, creating a hub of plates that are locked and loaded. As your coordinate measuring machine (CMM) works in the background, position your next workpiece on another plate so it’s ready to switch out for the next run. If you need more room to inspect parts, combine plates in a chain to extend your surface. While they’re not sturdy enough for use in machining, you can use them for light fabrication work, such as laser engraving.

When docked on a rail, the strong magnets in these plates hold them still. The lightweight aluminum makes them easy to lift and swap, and an anodized coating protects them from scratches and wear, even if you’re working with heavy parts.

Fixture Plates

4 Mounting Edges

Fixture plates hold components such as towers, clamps, and standoffs in the evenly spaced holes to raise and position parts.

4 Mounting Edges—Plates with four mounting edges can be rotated in 90° increments. Instead of having to reposition your workpieces, turn the plate to access other angles.

For when handcrafted artistry matters. These tables position your work with exact alignment on the X- and Y-axes. Unlike CNC machines, they don’t need programming, so they’re great for one-off parts and quick prototypes. They’re precision ground to ensure accurate cuts every time.

These tables mount on your milling machine or drill press. The thick handles give you a firm grip for smooth turning of the steel hand wheels. As the table slides on its axes, an adjustable steel gib minimizes sticking and slipping. Tighten the lock nuts to keep the table steady as you machine.

Tilting Table—Cut your work from any angle. In addition to the same features as the Standard-Table 50 lb. Load Capacity table, these also position your work at any angle between 0° and 90°. Tighten the hex bolts on the side plates to keep the table at your desired tilt.

50 lb. Load Capacity—Double the T-slots for twice as many fixturing possibilities. The four T-slots give you the space to make elaborate fixture setups or hold your work from multiple sides. Cut with trapezoid-shaped Acme threads, the internal X-Y screws minimize backlash and won't deform. Balanced to prevent unintentional movement, the crank handles take less effort to turn than hand wheels. With bulbous grips, these handles fit comfortably in your palm.

150 lb. Load Capacity—The highest weight capacity of any table we offer. The wide base keeps the table stable when machining your heaviest work. They’re long enough that workpieces won’t hang off the edge and become unbalanced. With X-axis hand wheels on both ends of the table, you can adjust them no matter where you’re standing.

Electric Welding Positioners

Mount a workpiece on these motorized turntables for smooth and continuous 360° rotary motion useful for creating circular welds. Turntables tilt and lock in place at angles up to 90° in 15° increments. Once the workpiece is attached to the turntable or chuck, press the foot pedal to start the motor. As the part rotates, your hands are free to focus on the weld.

Load capacity is reduced as the table is tilted.

Stationary Clamping Jaw Fixtures

Mount these fixtures to a milling machine, drill press, or other flat surface and use the jaws to grip workpieces. Their low-profile design maximizes tool clearance, which helps you machine efficiently. The jaws are precision ground to tight tolerances for repeatable centering that’s accurate within 0.02 mm. These fixtures are self-centering—they use scroll actuation, which means that all jaws move in unison to center the workpiece as they close.

Each fixture comes with reversible jaws, which you can install for either an inside or outside grip. Use the included wrench to open or close the jaws.

3 Reversible Jaws

Rotary Angle Indexers


Indexer with Workpiece Shown in Vise	Indexer with Workpiece

Transform your machine vise into an indexing system in seconds. These indexers help you position round workpieces at precise, repeatable angles for machining flats, hexes, and key slots. Slide them onto the end of a workpiece and secure with the set screw. These indexers attach directly to your workpiece, so you can move them from setup to setup without losing your reference point. These indexers are etched with graduation marks up to 360° so you can line up your workpiece with a machinist square. A hex, square, and octagon are cut into the face, so you don’t need to check the graduations for 45°, 60°, or 90° increments.

Indexing Collet Fixtures


1° Index Increments	15° Index Increments

Used with a 5C collet (sold separately), these fixtures rotate round, hex, or square workpieces up to 1 _1/8" diameter in precise increments. Also known as spindexers or punch formers, they are commonly used to drill holes into cylindrical parts, grind punches into precision shapes, and sharpen drill bits and end mills. To ensure accurate rotation, spindles are precision ground. Mount fixtures to a machine table for horizontal orientation or an angle plate for vertical. A through-hole accommodates long workpieces.

1° Index Increments—Fixtures with 1° index increments have an indexing plate with 36 holes for rotating in 10° steps and 10 additional holes for 1° refinements.

15° Index Increments—Fixtures with 15° index increments have 24 locking positions.

Collet Fixtures

Pair these fixtures with collets to tightly grip workpieces for machining. You can mount them on milling machines, drill presses, and other work surfaces. However, they’re not for use with lathes, grinders, or high-speed rotary tables. All have a through hole to accommodate long workpieces.

Lever Actuator

Lever fixtures have a handle that can be indexed to any position—no tools required. They’re often used for quickly swapping workpieces in and out, when a simple clamping mechanism is more important than consistent holding force. These fixtures keep the collet stationary while their sleeve clamps. Made from cast iron, they dampen vibration better than steel fixtures, though they’re less durable.

Collet Nut Actuator

Collet nut fixtures convert ER collets—typically used to hold tool bits—into holders for cylindrical workpieces. The tapered, slit design of the collet distributes clamping force evenly around a workpiece. This creates a stable, consistent grip that keeps your workpiece from shifting, even under 5-axis machining forces. These fixtures are made of steel to withstand the high clamping forces and frequent cycles of production environments.

Square Drive Actuator

Square-drive fixtures are designed for precise, repeatable workholding with consistent clamping force. They keep the collet stationary while their sleeve clamps. Made of steel, these fixtures are stronger and more wear resistant than cast iron fixtures, and they can hold up to higher clamping forces. They’re precision machined for accuracy. Use the included socket wrench to clamp and unclamp your workpiece or use a calibrated torque wrench to fine-tune the clamping force.

Indexing Jaw-Chuck Fixtures

More flexible than indexing collet fixtures for workholding—these fixtures hold a wide range of part sizes without swapping out collets. Also known as spindexers, they’re often used to drill hole patterns, shape punches, and sharpen cutting tools. With three jaws that move together, the chuck auto-centers parts and even grips workpieces that are out-of-round or have rough surfaces. Ground to tight tolerances, the base sits flat when mounted to machine tables in either a horizontal or vertical position, preventing misalignment. With a hole through their center, they have no trouble holding long parts too. The chuck comes off, so you can also use them as rotary tables.

High-Density Air/Hydraulic-Operated Collet Fixtures

Four Fixtures (Each Sold Separately)


Pull Back	Pull Back—Flange Mount

Fixed Length	Fixed Length—Flange Mount

Push a button to clamp or release multiple workpieces on your milling machine or drill press. To create a high-density setup, mount these fixtures and join them together using two connector bushings (sold separately) for each fixture you want to add. These fixtures have a through hole for clamping long workpieces.

Air or hydraulic pressure opens and closes the collets (not included). A good choice for heavy machining, these fixtures provide a tighter hold than you can achieve with manual power. You can operate multiple fixtures with a single valve (not included) and two hoses—one for supply and one for return. All are double acting, so they need air or hydraulic pressure both to open and close. This means that the workpiece stays locked in place even if you lose pressure. Clamping force depends on the air or hydraulic pressure of your system.

Top-Locking Screw—Fixtures with a top-locking screw allow for direct access to make adjustments without disassembling your setup.

Pull Back—Pull-back fixtures have tapered walls that press all sides of the collet evenly to center the workpiece—like how a mechanical pencil grips lead. They’re less precise than fixed-length fixtures because the workpiece may shift slightly during clamping.

Fixed Length—Fixed-length fixtures, also known as dead-length fixtures, keep the collet stationary while they clamp onto a workpiece. Use them to precisely machine holes, slots, and contours exactly where you need them. Since these fixtures position workpieces consistently, they’re often used for high-volume production runs. You can also rotate them on an indexer or rotary table without losing your reference point.
