Challenge Precision Plates & Stands

Solid Tooling Bases

picture

Provide solid, accurate, precision-machined bases for use in N/C or standard machine fixturing, as tooling pallets or subplates, surface plates for layout and inspection, or optical bases.

Cored Bench Plates

picture

Cored Bench Plates come in 2" and 4" models and can be used as fixture bases or small surface plates. Also excellent for precision layout and inspection.

10"x14" Duplex Bench Blocks

picture

These duplex bench blocks are 2-3/8” thick to provide an accurate surface plate of sufficient strength and thickness that can be used on a bench or other inaccurate surface and still retain its accuracy.

6" Clamp Edge Plates

picture

These 6” cored plates have solid 2” thick edges which overhang the plate itself by 2”. The edge is convenient for clamping work during layout and assembly operations. Overall height with optional stand is 36”.

Three Point Surface Plates

picture

Three point surface plates provide a precise reference surface for toolmaking, layout, or checking the accuracy of other surfaces. The three point bearing pads and rigid ribbed construction permit support by less accurate surfaces without disturbing the surface
accuracy. Wooden cover supplied with each plate.

Standard 6" Layout Plates

picture

These plates can be used for a wide variety of applications including precision layout and assembly, checking tables, large fixture or machine bases, set-up plates, laboratory test plates, or stable surfaces for optical systems. They have 1” thick tops and are heavily ribbed for good surface rigidity under heavy loads. They are cored for lightness and the sides and ends are machined square to the top surface. They can be used individually or combined for nearly any size.

Layout Plate Stands

picture

Challenge welded all-steel stands are specially designed to provide rigid support for Challenge plates. They are equipped with adjusting screws at key points so the plates can be properly leveled or releveled as needed.


Unless otherwise specified, stands are constructed to provide a working height of 36” at the plate surface. Example: For a 6” plate, the stands are 30” high; for a 4” plate they are 32”; and for a 2” plate they are 34”.

6" Floor Plates

picture

These plates are available in a wide range of sizes up to 120” wide and 336” long in a one-piece design. Unlimited size when used in combination. Other thicknesses can also be provided on special order. They provide the most accurate type of semi-steel base when mounted on a solid concrete foundation of suitable thickness. Specially designed leveling devices are supplied with the plates, accessible from the top of the plate. Recessing the plate to floor level allows easier on- and-off movement of heavy loads. The pit depth is equal to plus one- (1) inch of the thickness of the plate.

Steel Weldments

picture

Especially designed for boring mills to bring the work piece up to working height. The weldments are heavily ribbed to prevent table sag. A base flange is provided at the bottom for use in mounting on a foundation, floor plate, or machine base. Made of steel weldments. All sides and bottom are machine finished to provide smooth mating surfaces to a floor plate, machine base, or for use in multiple sections.
