机械加工通常都是有層加工,为了提高工效,节约材料,由有層加工改变为无層加工,这是机械加工技术革新的主要方向之一。我车间近年来在无層加工方面创造了很多像冷墩、滾丝、滾花等新工艺。现将切向进给无支架滾丝法介绍如下。这种滚丝法只要在普通的滚丝机上即可进 Mechanical processing is usually a layer of processing, in order to improve work efficiency, save material, from layer processing to non-layer processing, which is one of the main directions of mechanical processing technology innovation. In recent years, my workshop has created a lot of new processes such as cold pier, wire rolling and knurling without layer processing. Now tangential feed without stent rolling method is as follows. This rolling method as long as the ordinary rolling machine can enter
