  8.  · Naturally the face mills need a shank but as far as function goes they seem to be the same. Milling with a 3" or 4" diameter carbide end mill secured by an R8 collet seems to blur the description of what an end mill is versus a face mill. Just for the record when I need to face I dig out a face mill simply because it covers more ground quicker.

  9. Explain the difference between milling and welding. Milling is a form of cutting where by a metal is made into to a specified geometry by removing excess material using various kinds of tooling leaving a finished part matching a set of specifications. Welding is a fabrication process which joins two pieces of material. This can be done by ...

  10. UNIVERSAL HORIZONTAL MILLING MACHINE The basic difference between a universal horizontal milling machine and a plain horizontal milling machine is the addition of a table swivel housing between the table and the saddle of the universal machine. This permits the table to swing up to 45° in either direction for angular and helical milling ...

  11. This article will explain about 3-2-1 principle of jig fixture design. Learn how to use the 3-2-1 principle for designing of drilling and milling fixture for precision, reliable machining.

  12. Mill scale is a flaky surface that can be found on iron oxides and metals that have been hot rolled. Mill scale forms on exterior surfaces of sheets and plates as they are being manufactured through rolling steel billets and hot iron into rolling mills. Mill scale typically consists of iron oxides that are bluish black.

  14.  · Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals.MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding …

  15.  · Hey everyone I have to ask what's the difference between an inverter type welding machine and a non-inverter type. What I have noticed is that inverter type welding machine draws less input current but other than that I don't know a thing. I have an inverter type MIG welding machine and tried it in aluminum. Oh man the result was a disaster.
