Abstract

A multi-component gear cutting tool that is rotatable about an axis of rotation. The gear cutting tool includes a tool body extending axially lengthwise between a first end and a second end with the tool body being made of a first material. The gear cutting tool further includes a cutting tip attached to the tool body at one of the first end and the second end. The cutting tip includes an outer axial-facing cutting end with the cutting end having a plurality of cutting faces. The cutting tip is made of a second material different than the first material and the cutting tip is attached to the tool body via brazing.

Abstract

A tool head (52) for a machine tool comprising a plurality of tool spindles (54, 56, 58) with each tool spindle being rotatable about a respective tool axis. The plurality of tool spindles comprises at least a first tool spindle (54) rotatable about a first tool axis, a second tool spindle (56) rotatable about a second tool axis and a third tool spindle (58) being rotatable about a third tool axis with the first, second and third tool axes being parallel to one another. The first, second and third tool spindles are arranged on the tool head whereby one of the first, second and third tool spindles faces a first direction and the other two of the first, second and third tool spindles face a second direction with the first and second directions being 180 degrees apart. The tool spindles are preferably grinding spindles on a machine (32) for grinding bevel gear cutting tools (2).

Abstract

A multi-axis computer controlled machine tool for relief grinding of single and multiple start threaded hobs (46). The machine comprises an angular oriented spindle (65) that can be angularly (swivel) positioned thereby providing the flexibility to utilize both cup- shaped grinding wheels (55) and pencil-shaped grinding wheels (52) for grinding of hob and milling cutter relieved tooth geometry without exchanging grinding spindles assemblies or modifying the machine construction to accommodate two types of grinding methods or utilizing an additional machine axis for the spindle re-orientation.
