Fixture Plates

Lay the foundation for your fixturing setup. These plates have a grid with evenly spaced threaded holes to install angle brackets and other fixturing components. They’re often used to help secure workpieces for measuring and inspecting. Just like a battleship gameboard, the edges are labeled with letters and numbers, making it easy to identify holes. While these lightweight plates aren’t for machining, you can use them for light fabrication jobs, such as laser marking. All can be attached to your table with clamps (not included), making them easy to remove and swap.

Fixture Plates

Plates with mounting holes can be bolted down on fixture tables for more stability than those held down by clamps. Make sure the grid of your plate and table align for precise measurements.

Anodized Aluminum—Anodized aluminum plates are often used with coordinate measuring machines (CMMs) and optical comparators. The coating protects them from scratches and wear, even when you’re working with heavy parts.

Acrylic Plastic—Acrylic plastic plates are clear, so they let light pass through them. This gives you or your vison system unobstructed views of your workpiece from all angles.

Grid Fixture Plates

Use these plates as a foundation for your fixturing setups. Precision ground to tight tolerances, they have holes in a grid pattern for accurate, repeatable positioning.

Rectangular Fixture Plates

Fixture plates are thinner and lighter in weight than subplates, so they're often used to build setups that are swapped in and out of machines.

A36 Low-Carbon Steel—A36 low-carbon steel plates are stronger than 7050 aluminum plates, and their threaded holes are tapped directly into the plate. Some also have unthreaded holes, which are jig-bored and lined with a precision bushing to help reduce wear and ensure accurate placement.

7050 Aluminum—7050 aluminum plates are lighter in weight than A36 low-carbon steel plates. All of their holes are threaded—they’re lined with hardened steel inserts to make them more durable, rigid, and wear-resistant.

For Threaded Holes and For Unthreaded Holes—Add chip plugs (sold separately) to keep chips and shavings from clogging or damaging unused holes.

Square Subplates

Image of Attribute. Front orientation. Contains Annotated. Grid Fixture Plates. Grid Fixture Plates, Square.

Subplates are thicker and heavier than fixture plates, so they’re often used as permanent assemblies in horizontal milling machines. You can use them as a base for fixture plates or build setups directly onto them. Made from A36 low-carbon steel, also known as mild steel, they resist flexing under heavy loads and hold up to repeated wear. The holes are lined with a precision bushing and a threaded insert to help locate fasteners, so you can clamp parts accurately and securely. Both are hardened to resist wear, but you can also replace them. Subplates also come with a plastic chip plug in each hole to block debris when they're not in use.

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


1 Mounting Edge	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.

Fixturing for Parts Inspection

From towers and brackets to standoffs and supports, these components are the building blocks for your custom fixturing setup. They elevate parts so you can access a variety of angles for measuring and inspecting while protecting your measuring device from hitting the inspection table. You’ll often see them used with coordinate measuring machines (CMMs). They’re not for use in machining applications.

Fixture Towers

Fixture towers give you four vertical grids and a small horizontal one on top, so you can set up custom scaffolds to position parts in several planes. Their height makes them useful for propping up large workpieces. Each tower can uphold multiple parts. The threaded holes on the vertical grids are labeled with letters and numbers, making it easy to identify holes.

Angle Brackets

Angle brackets create a 90° mounting point, so you can secure small workpieces with supports. Shorter than towers, they’re a good choice for parts that are about the size of your palm. The base bolts into your surface, so these brackets won’t budge.

Fixture Tables for Parts Inspection

Create a fixture setup on these tables to inspect your parts. A built-in threaded fixture plate gives you endless possibilities to attach CMM fixturing clamps and other accessories right where you need them. Labeled around the edge with letters and numbers—just like a battleship game board—it’s easy to identify holes and repeat tasks. To adjust their height slightly and move these tables around your workspace, they come with leveling casters. Tables come assembled.

Grid Fixture Plates for Welding

Build fixturing setups for welding onto these plates. They have _5/8” unthreaded holes with 2” center-to-center spacing, so they’re compatible with clamps, stops, V-blocks, and other components. Made from nitrided steel, they have a hardened surface that resists wear, prevents corrosion, and keeps weld spatter from sticking. They’re easy to maintain and they hold their shape over time. To add resistance to heat and spatter, apply welding antispatter to all the components in your setup.

V-Blocks

Mount V-blocks to the fixture plate to hold round workpieces in place.

Multiple Studs—V-blocks with multiple studs slot into at least two grid holes, which keeps them from shifting when you move workpieces in or out. They have two rows of mounting holes, so you can position them at a 45° or 90° angle on your grid.

Pivoting V-Blocks—Pivoting V-blocks can hold both the outer and inner diameter of your workpiece. They can go from cradling the outside of a pipe at 60°, to lying completely flat, to gripping the inside of a pipe at a 60° angle.

Fixture Columns

Clamp multiple parts or fixtures to these columns to speed up your machining process. Also known as tombstones, they have multiple faces for building dense, efficient setups. Each face is precision-machined for accurate positioning. Made from cast iron, these columns are rigid enough to limit vibration and stabilize your workpieces during machining.

Grid


Square	Rectangle	Cross

Grid columns have industry-standard hole patterns. The holes are lined with a precision bushing and a threaded insert to help locate fasteners, so you can clamp parts accurately and securely. Both are hardened to resist wear. These columns also come with a plastic chip plug for each hole—plug unused holes to keep debris from clogging them or causing damage.

Square—Square columns have four equal faces for balanced machining on each side.

Rectangle—Rectangle columns have two wide faces for larger setups and two narrow faces for smaller ones. The narrow faces can also help reduce tool interference.

Cross—Cross columns have four equal faces, similar to square columns, but cutouts at each corner give you more tool clearance.
