Arbor, Extensions & Reductions
Arbors are manufactured in accordance with DIN 69871 AD-B, MAS 403 BT AD+B, DIN 2080, ANSI-CAT, DIN 69893 hardened and ground to AT3 tolerance and the ISO 26623-1 and are made of carburized steel.
Arbor sizes MHD’ 80, 110, and 140 are recommended for heavy milling operations and for bores deeper than 250 mm and exceeding 125 mm in diameter. Special arbors are available upon request.
Extensions of various lengths are available for each MHD’ size, which make it possible to optimize the desired machining depth.
Reductions are available for MHD’ components of a smaller size can be used by means of adaptor sleeves which allow greater interchangeability and ensure tool stability.
