Alpha Table Overview

Alpha Table Overview

The toughest, flattest, hardest working welding tables.

The Alpha family consists of our 5 sided table systems, combined with our patent-exclusive, reversible, and replaceable top and side plates.

Alpha tables available in both metric and inch spacing and 28 mm, and 5/8″ diameter boreholes, respectively.

Alpha 28 is an Ultra heavy duty 5-sided table with 28 mm diameter boreholes​ while Alpha 5/8 is Heavy duty 5-sided table with 5/8" diameter boreholes​.

All top plates are constructed from heat-treated steel, hardened to 550 Vickers, and finished with a nitrite coating with a case depth of .0004-.0008″.

Table Top Plates are made from tough P20 low alloy tool steel for a 60.5HRC hardness, then CNC machined for flatness.

QPQ Nitriding Treatment provides corrosion and weld spatter resistance for superior performance and wear.

Patented, self-locating Table Plates can be repositioned, then easily realigned to the original position. Reposition the table plates as needed to increase the width of the table for oversized or complex fixtures.

What people say about us:

I am still waiting on the fixture kit but so far am very impressed with the craftsmanship put into this table. It is super heavy but easy to assemble with the help of a forklift.

Kevin T

Morro Bay, CA

These tables are exceeding my expectations. They are built much heavier than what I envisioned.

Don W

Manitowoc, WI

Excellent size. Good access for mounting and tool insertion. Very stiff. Very straight.

Stronger, More Rigid Frame

The machined tubular frame construction of the Alpha 28 table provides improved flatness and torsional stiffness compared to plate only frames. The rigid frame with modular plates on the Alpha 28 means less high spots and less twisting compared to welded plate designs. The welded construction of a plate only design often leads to distortion and high spots around the corners and center.

Alpha 28 Tubular Frame Design

Welded Plate Design

Each plate is made from a low alloy tool steel that’s tough enough for use in the mold making industry. After surface grinding and machining, each plate is further enhanced with a QPQ nitriding process that improves hardness, corrosion resistance, and resistance to weld spatter.

Plates on the table can be repositioned, or removed as applications dictate; a patented plate locating system means the spacing of the holes are always within tolerance without the need for special re-calibration.

The unique and versatile Alpha 28 Tables are complemented by a complete range of Modular Fixturing Components and Fixturing Kits.

The system of Ø28 mm CNC machined table holes in a 100 mm grid pattern is the ideal platform for rapid, precise, and accurate fixturing.

The patented Locating Bushing design allows you to easily remove, re-position, re-align, and reverse the table plates. Table Plates can be positioned to create the custom work surface configuration required for each unique fixturing application.

Alpha 28 tables combine the rigidity and accuracy of a welded and machined frame with the flatness of precision ground, CNC machined plates.
