The Rockwell brothers were metallurgists working in a Connecticut ball bearing factory back in the early 1900s. They recognized the need for accurately and quickly testing metal strength in bearing races. They also required a clear method for reporting strength test results. Stanley Rockwell patented the Rockwell testing method in 1914.

It's a wee bit more surprising when the bolt-on kit is sold specifically as an option for a specific machine that you bought specifically with this factory-supplied option. Allow me to explain. Regular readers know I recently adopted a PM-25MV vertical mill from Precision Matthews. It has proven to be an excellent machine, and I recommend it ...

30 NMTB Taper 7/8" Diameter Milling Machine Arbor This is a No.30 NMTB Taper milling machine arbor that came with a Rockwell horizontal milling machine that I bought a while back. It is a Style'B' arbor that has a non-standard.625 diameter x 1-5/8" long pilot and an arbor length of 8-1/4" from the shoulder to the nut.

The Rockwell rating is a scale that is used to measure the hardness of a material. An example is stainless steel AUS-8, which usually 57-59 Rc. The Rockwell hardness test is the industry standard for knives. When a range is listed, it means that whatever variation occurs in the hardening process will fall within that range.

Universal means swiveling table, which the Rockwell does not have. You are looking at a "Double Duty" horizontal-vertical milling machine, as Rockwell called it. It came with both an overarm and a vertical head that replaced the overarm. It would be a nice machine if complete and in good condition. It weighs 300 pounds more than the vertical.

The Rockwell hardness scale gets its name from its inventors, Hugh M. Rockwell and Stanley P. Rockwell. The Rockwell brothers were metallurgists working in a Connecticut ball bearing factory back in the early 1900s. They recognized the need for accurately and quickly testing metal strength in bearing races.

Overview of the mill. I recently acquired this Rockwell 21-122 Horizontal/Vertical milling machine from my local Craigslist. It's in remarkably good shape; most of the moving parts are free, the ways look very clean, the table surface is relatively free from dings and not a whole of obvious rust. The quill doesn't have full travel though.

Rockwell hardness test is the most commonly used method for indentation hardness measurements. The value of Rockwell hardness is accompanied by the scale used. Depending on the material being tested, an appropriate scale must be selected. This hardness scale gives information on the type of indenter-load combination used.

Anybody know of any Rockwell Vertical Mill (21-100) parts available? Specifically the Fine Feed housing and Quill Feed Lever. I can make the Quill Lever, but if something is available on the 'cheap' I'd buy. Bridgeport Quill Feeds have too large a bore and I don't feel like cutting a shim to stuff in. Besides that they want too much.

What is Rockwell hardness test? The Rockwell hardness test is a hardness measuring method using Rockwell scale to measure the depth of penetration of an indenter under a large load on the surface. Rockwell scale has different scales denoted by a single letter. The higher the number in the scales means the harder is the material.
