clamp knurling tool The most common type of knurling tool is bump type knurling tool. It is simply a holder for one or two knurls that is held in the tool post of the lathe and pushed against the rotating workpiece to form the knurl.
Gang Milling Gang milling is the term applied to an operation in which two or more milling cutters are mounted on the same arbor and used when cutting horizontal surfaces. All cutters may perform the same type of operation or each cutter may perform a different type of operation.
Figure 18. Gang Milling 6.4. Straddle Milling In straddle milling, a group of spacers is mounted in between two side and face milling cutters on the spindle arbor as shown in figure 19. for the milling of two surfaces parallel to each other at a given distance.
Apr 25, 2013· Milling machine is one of the most versatile conventional machine tools with a wide range of metal cutting capability. Many complicated operations such as indexing, gang milling, and straddle milling etc. can be carried out on a milling machine.
Milling practice is to use a figure known as "Tooth load". This is the feed per revolution per tooth, so that the feed in ins/min is the product of speed in RPM, number of teeth, and tooth load. Tooth load varies very little from one material to another. but it does go down rapidly as the cutters get smaller.
