【発明の名称】切断歯、特に鋸歯を有する加工物を機械加工するための機械
Document Type and Number:
Japanese Patent JP2001521825
Kind Code:
A
Abstract:
A tool head (46) in which a tool spindle (52), adapted to be equipped with a disc-shaped tool (100), is supported so as to be driven in rotation about a spindle axis (C), is associated with a workpiece support (82) on which a workpiece (10) can be arranged such that the tooth tip (18) of a cutting tooth (12) to be machined will lie on a stationary reference axis (A). The tool head (46) is movably supported by means of a reciprocating slide (34) which is movable back and forth along a reciprocating slide guide means (32) transversely of the reference axis (A), by means of a feed slide (24) adapted to be advanced along a feed slide guide means (22) transversely of the reciprocating slide guide means (32), and by a pivot bearing means (42) defining a pivot axis (B) parallel to the reciprocating slide guide means (32). The tool head (46) is pivotable about the pivot axis (B) by a pivot drive means (60) from a normal position for machining surfaces of the cutting teeth (12) which extend parallel to the reference axis (A) into inclined positions for machining oblique surfaces of the cutting teeth (12). The distance (x) by which the active face (106) of the tool (100) is spaced from the pivot axis (B) can be measured by a measuring means (108). A numerical control means (98) makes sure that the feed slide (24) adopts a position at which the spacing of the pivot axis (B) from the reference axis (A) equals the distance (x) when the tool head (46) is in the normal position, and that the feed slide (24) adopts a respective corrected position when the tool head (46) is in an inclined position.
