Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment, in particular to a small horizontal lathe for machining shaft parts. Background Art

[0002] Ordinary lathes are horizontal lathes that can process various types of workpieces such as shafts, disks, rings, etc. in various processes. They are often used to process internal and external rotating surfaces, end faces, and various internal and external threads of workpieces. With corresponding tools and accessories, they can also perform drilling, reaming, tapping, knurling, etc. Ordinary lathes are the most widely used type of lathes, accounting for about 65% of the total number of lathes. Because their spindles are placed horizontally, they are called horizontal lathes.

[0003] At present, small horizontal lathes for shaft parts are usually processed manually. Lathes usually process parts by cutting. Extremely high heat is generated between the turning tool and the part during cutting. Most of the heat on the part will be taken away by the generated debris. However, the debris splashes everywhere during processing. When the debris with extremely high temperature comes into contact with the staff, it will cause harm to the staff. In addition, due to the long-term working of the turning tool and the high temperature, the turning tool is easily deformed and the tool head often sticks to the debris during processing, resulting in reduced processing accuracy of the parts.
