Abstract

This steady rest enables precision machining of small and very small diameter wire and similar stock. A small plate of brass or like material is mounted on a bracket affixed to the carriage of the machine tool as close to the cutting tool as practicable so that the rest moves forward with the cutting tool. The chuck used for feeding the stock is first fitted with a boring tool and the plate is bored, after which the stock replaces the boring tool and is fed to the cutting position.

Precision Steady Rest for Very Small Wire Stock

This steady rest enables precision machining of small and very small diameter wire and similar stock. A small plate of brass or like material is mounted on a bracket affixed to the carriage of the machine tool as close to the cutting tool as practicable so that the rest moves forward with the cutting tool. The chuck used for feeding the stock is first fitted with a boring tool and the plate is bored, after which the stock replaces the boring tool and is fed to the cutting position.

The drawing shows a machine tool in the form of a portion of an automatic precision cutting lathe 10 having a spindle 12 fitted with a collet 14 and having a moving carriage 16 on which is mounted a cutting tool post 18 of conventional form for holding a cutting tool 20 also of conventional form.

Wire 30 or similar stock with very small diameter is fed through the lathe spindle and collet 14 for operation by the cutting tool 20. A bracket is 32 is affixed to the lathe carriage 16, and a disk or similarly shaped plate 34 is fastened to the bracket 32 by a single machine bolt and spring washer combination 36. The plate 34 is initially mounted above the lathe carriage 16 on the bracket 32 and bored by inserting a boring tool (not shown) in the collet 14. The bore in the plate 34 is made a few thousandths of an inch larger than the stock and exactly centered with the center line of the spindle 12. Once the plate is bored, the boring tool is r...
