## Abstract

A contrivance for the machining of cylindrical surfaces on metal-cutting lathes in a housing whereof there are contained a tool head with at least one tool, a head with deforming rollers, and a system for feeding coolant-lubricant to the tool and deforming rollers. The system for feeding coolant-lubricant incorporates a chamber which is located inside the housing between the tool head and the head with deforming rollers, communicates with a source of coolant-lubricant, and is also connected to the tool head with deforming rollers through at least one nozzle arranged so that the jet issuing therefrom is aimed at the cutting edge of the tool.

## Claims

### Claim 1

A contrivance for the machining of cylindrical surfaces on work supported for rotation on metal-cutting lathes comprising a housing; a tool head fixed inside said housing; at least one tool clamped in said tool head and having a cutting edge; a head with deforming rollers, said head being located in said housing behind said tool head; a system for feeding coolant-lubricant incorporating a source of coolant-lubricant, a chamber disposed in said housing between said tool head and said head with deforming rollers, said chamber being connected to said source of coolant-lubricant and to said head with deforming rollers, at least one nozzle fitted in said housing between said chamber and said tool head so that the jet issuing therefrom is aimed at the cutting edge of at least one said tool, the surface of said work defining one wall of said nozzle, and said nozzle confining the coolant-lubricant flow to direct and confine said flow to issue againt the cutting edge of said tool.

### Claim 2 (depends on 1)

A contrivance as claimed in claim 1, wherein, if use is made of the tool head with two oppositely-arranged tools, the nozzles are provided in the form of half cylinders axially disposed in a cylindrical sleeve fitted in the housing between the chamber and the tool head.
