I want to build a boring head for my Milling machine, the milling machine uses a R8 Taper and I was thinking of using 1/2" or 5/8" boring bars. Does any one have a good plan for building a boring head that is not to complicated? Thanks in advance. ;D

This might seem like a dumb question and it probably is but I do not know how to gauge whether a carbide insert used in a milling machine needs replacing. I understand that if the insert is chipped it needs to be replaced, I understand how to evaluate HSS end mills for sharpness. Is the answer...

Hello All; The questions keep coming! I have been making up several sets of parallels on my milling machine and have been hogging material for many hours. I have been using a 1 ¼” carbide insert cutter to do the roughing to size. My question has to with feed rate on the X-axes. The speed that...

Hello All; I received these two rectangular pieces with my 5" milling vice, there was also two small screws that came with it. I have looked at the vice trying to find where they might fit but have not found any small bolt holes. I at first thought they where stop blocks but can not find...

Sounds simple but more to this than it seems! Yes, one can wait until the cutter just burns its way through steel, but then the cutter is ruined. I have been told to check for a valley across between the tips with a small steel ruler and to look for shiny spots on the cutting edge of the end...

Has anyone made soft jaws out of aluminum for a milling machine vice? If so, how thick where the jaws? Where they trued up while on the vice? Does anyone have plans for this project? I have a 5" Kurt style vice which I would like to convert to an soft style of jaws for a demanding project.

Hello All; Let me start off with what I am looking for. I have a milling machine and am looking for a inexpensive way of attaching a 3-axis DRO system. I am a amateur user, which means I do not do commercial or large production runs so the cost of this system has to be kept low. Regarding the...

Hello; I have just started milling and have acquired several end mills of different flute configuration and size. In addition I now have aquired a 1 1/4" indexable end mill. I did this because I had read that one should use the largest cutter one has that will do the job. At present I have...
