Setup, layout, and alignment tools are used for positioning, layout, setup, and alignment applications. 1-2-3 setup blocks raise workpieces off of a machine table for inspection and layout applications. Dial and electronic tool setters position a workpiece or machine spindle. Digital readout (DRO) counters track the position of workpieces to improve speed and accuracy in machining processes. Digital and linear scales for DRO measure absolute or relative length dimensions along a horizontal or vertical axis. Edge and center finders ensure that a spindle is properly positioned at the edge or center of a workpiece or bore. Parallels provide a flat and parallel base for machining. Pin vises hold wire, small stock, reamers, scriber points, and drills. Precision and machinist levels indicate horizontal evenness and incline when setting up machinery in high-accuracy applications. Shaft alignment lasers check the alignment of motor bearings and shafts in hard-to-reach areas. Sine bars verify that angled workpieces have been accurately machined. Sine plates hold workpieces at a precise angle to ensure accurate machining. Spindle squares check the squareness of milling machine heads. Straight edges are used to scribe straight lines, make straight cuts, and check flatness of material edges and mated surfaces. V-blocks position cylindrical and rectangular workpieces during inspection or production.
