METHOD FOR MANUFACTURING BOLT AND MANUFACTURING DEVICE THEREFORE
PURPOSE:To cut the length a bolt errors within several mum - several tens mum by abutting the head seat of the bolt to the flat face of a bolt holder as a standard face, moving as the head seat between a pair of cutting tools, and cutting the top of the head and the top of a screw simultaneously.

| description | PURPOSE:To cut the length a bolt errors within several mum - several tens mum by abutting the head seat of the bolt to the flat face of a bolt holder as a standard face, moving as the head seat between a pair of cutting tools, and cutting the top of the head and the top of a screw simultaneously. CONSTITUTION:A plurality of work holders 13 is arranged concentrically at the work fitting disk 12 of driving shaft 9 pivoted between left and right frame 2, 3, a bolt 35 as a work is inserted in the work holder 13, the seat of the head of the bolt is abutted to one face (left side) of the work holder 13 and is clamped with a bolt clamp 14. While this settings carried, the work fitting disk 12 is rotated and is passed between a pair of cutting tool 20D, 20D', the distance of which is a several mum - a several tens mum relative to a standard length, of spindle unit 20, 20' for rough cutting, middle cutting and finish cutting fitted to left and right frames 2, 3, the head and the top of the bolt 35 are simultaneously cut in turn. Thus, precise bolts can be mass-produced. |
