TOOLING BLOCKS HEIGHT BLOCKS

APPLICATIONS Challenge Tooling Blocks (Tombstones) provide apractical method of holding work accurately in a vertical or horizontalplane for CNC and NC machining operations. They can be mounteddirectly on the machine table or used in conjunction with rotary tables.The four working surfaces permit mounting of four work pieces at onetime. Quantity production jobs can be set up so that finished work piecescan be removed and new ones put in place while the machine is workingon the next piece.

TOLERANCES Base and sides milled flat, parallel & square to .001” per12”. Most sizes can be finished with a ground finish for tighter tolerancerequirements.

OPTIONS Other sizes and forms available. Mounting and positioningholes, T-slots, locating bushings, and other mounting features.

APPLICATIONS Used singly or in combination to provide an accuratereference plane parallel to and at the desired height from the workingsurface for gauging and measuring.

TOLERANCES The top and bottom surfaces are precision ground andaccurate in height to ±.0005” and parallel within .00025” within 6”.

OPTIONS Available in matched pairs within .00025” up to 10” or within.0005” up to 20”.

Blocks are approximately 7” square.

This is an example of how work can bemounted on the vertical and/or horizontalplanes of a tooling block for CNC or NC workon four identical items.

Challenge Granite Surface Plates offer very accurate, stable, precisionsurfaces that can be used for layout, gauging, and inspection. These platesalso can be used as bases for fixtures, coordinate measuring machines,and other machines. They are self-supporting, have a low co-efficient ofexpansion, and a low degree of surface deflection under normal loads. Oursurface plates meet or exceed Federal Specification GGG-P-463c and arein compliance with MIL-STD-45662A. Final inspection and calibration of everysurface plate is accomplished by use of an Auto-Collimator. A certificate ofaccuracy, traceable to the National Institute of Standards and Technology, isfurnished with all surface plates. All plates have a thickness capable ofsupporting a total normal load equal to 100 pounds for each square foot ofsurface plate area loaded in the center of the plate without defelecting theplate along a diagonal line more than one-half the flatness tolerance. CharcoalBlack granite is standard except for plates larger than 48” x 72” which areSierra Grey. Pink Granite is available as an option in most sizes.
