The term multi machining is applied when a item is machined in a single, very advanced CNC machine; from raw material to completed piece. Multi machining is the latest development of machine tool, which allows every part of the process, i.e. machining, turning, milling, boring, threading, etc. to be accomplished in the same sequence of operation. There are many advantageous to this process: The elimination of several mountings and machines, the opportunity of unstaffed production as a result of automatic material feed, as well as automatic removal of the items from the mould, significantly lower error rate, and significantly higher accuracy.
KK Metal can do multi machining of items utilising automatic material feed and removal of the item from the mould in diameters up to 80 mm, and chucks (one-piece) up to a diameter of 355 mm. We have many years of experience in automatic machining of steels and metals including stainless and acid-proof steel.
Multi machining – from raw material to finished product
Traditionally, turning is defined as machining in a machine, in which the item is rotated, and the tools fixed, whereas milling entails rotating tools and a fixed item. Multi machining is defined as a machine, in which both the tools and item can be fixed and made to rotate. The definition of multi machining further entails that the entire process can be done, thus raw material enters the machine and finished pieces exit.
This type of machine is typically a powerful CNC lathe, which is “extended” with rotating tools, several movable axis’, and an additional sub spindle for the item, to facilitate the possibility of working the item in both ends.
Machines that can perform multi machining are highly advanced and expensive, but because of advantages such as production time, precision of manufacturing, and the possibility of unstaffed operation, multi machining is the future solution.
