Micrometer Spacing Collars, Arbor Collars and Shims

Micrometer Spacing Collars

When two or more milling cutters are assembled on an arbor, it is essential to maintain accurately, the spacing dimensions between cutters, throughout production.

EUCO micrometer spacing collars are British made and used world-wide to provide rapid and accurate adjustment in an otherwise inflexible set-up. The material is an alloy steel specially selected for wear-resistance and durability, satin chrome plated with faces lapped.

All collars have a thread pitch of 1 mm. The engraved scale on imperial collars is provided with 40 divisions, every fourth division is numbered (0-9). Each graduation is .001" and adjustment is accurate to approximately .0005". Any closer adjustment is easily made after a trial cut. Metric collars have 50 divisions; every fifth division is numbered (0-9). Each graduation is .02mm and adjustment is accurate to approximately .01 mm.

Arbor Spacing Collars

Arbor spacing collars are used when gang milling for fixed spacing across a standard range assuring accurate positioning of milling cutters.
