Description

Stud milling device

Technical Field

Background

The stud is used as an indispensable fastener in the industries of machinery, automobiles, aerospace and the like, and the machining precision and the surface quality of the stud are directly related to the performance and the service life of a product. Among the many machining methods, milling is favored because of its high efficiency and high precision.

However, in efficient operation of stud milling, a troublesome problem is also associated with the generation of metal shavings. These tiny metal sheets generated by the interaction of the cutter and the stud inevitably scatter around the machine tool, which constitutes a serious threat to the precision, stability and service life of the machine tool. Once the scraps invade into gaps of precise parts such as guide rails, screw rods and the like, the machining precision of a machine tool is affected, and the parts are possibly worn and even damaged due to long-term accumulation. In addition, the existence of the chippings increases friction and resistance during the operation of the machine tool, so that the energy consumption and the temperature rise are caused to rise, and the machining efficiency and the quality are further affected. More tricky, these shavings, especially those parts that are small and sticky, are extremely difficult to clean. They are tenaciously attached to the machine tool, which presents a significant challenge for routine cleaning and maintenance work. If not removed in time, the residual shavings can also cause rust and corrosion of the machine tool, further exacerbating equipment aging. Therefore, how to effectively solve the chipping problem and ensure the cleaning and long service life of a machine tool while pursuing high efficiency and high precision of stud milling has become a technical problem to be solved currently.
