Jointing technology - MICHAEL WEINIG (USA)

Jointing technology Top quality at high feed speeds

To guarantee a consistently high surface quality for the work pieces, the joint land which appears on the tip of the knife must not exceed a specific width. This must not exceed 0.5 mm in softwood or 0.7 mm in hardwood.

Jointing stones made of ceramic bonded mineral powders are used for HSS knives while special WEINIG jointing stones are used for carbide knives.
