LOCATING WORK ACCURATELY ON THE FACEPLATE

摘要

The four jaw chuck is undeniably a versatile piece of equipment for the lathe user. I'm sure that you, like I do, make extensive use of your four jaw chuck. The four jaw chuck was developed from the lathe faceplate and locating dog system so it shouldn't be surprising that there are times when I find that I can achieve a more accurate and repeatable result by locating the workpiece on an angleplate that is mounted on the lathe faceplate. I'm particularly thinking of components that need two parallel bores but equally suited are the production of locomotive axleboxes, the machining of valve rod locations in steam chests and the boring of some steam engine cylinders.
