Tips for Stainless Steel Machining.

 
Here are a list of tips for stainless steel machining:

1. Use a tool that has higher thermal-conductivity

See firstly the Low thermal-conductivity of stainless steels accelerates tool for the wear of a resulting from a decline in the hardness of the cutting edge of an insert, this is mainly due to the heat piling up. It is the better to use a tool that has a very higher thermal conductivity and get it with an enough coolant.

2. Sharper cutting edge-line

It is too much necessary to proper utilize a larger rake-angles and a wider chip-breaker lands to comes for the reduce of as a cutting-load pressure and prevent build-up on the edge. This will mostly help us to provide a better chip control to an operator.

3. Optimal cutting condition

Inappropriate components for the machining conditions like extremely as a very low or high speeds or low feeds can cause of the poor tool life due to work hardening of work pieces.

4. Choose an appropriate tool

Tools for the stainless steel should have a good toughness of the attributes, and the enough of strength on their edge line (cutting edge) & a higher film adhesion.

Refinishing a Metal File Cabinet.


Hey dudes I have asked the question in the forums that “How to sand and clean a metal file cabinet, then shoot it with automobile finish. February 8, 2011.”But my real question is that I know very well that this is not a wood finishing, but it is also a finishing related process. I also know from the reading past posts in the forums that some of you have the ideas about the auto finishing experience. I need to do the re-shoot a file of the cabinet (metal) properly, and I picked up a single stage for the auto finish (Nason). What kinds of preparation work that do I need to do? There are a couple of the small scratches that go to a metal; otherwise, we will be able to the original finish is intact. Do I need to shoot a primer first?
After some days I get a lot of responses of the question. But I will show you the some of the response details – Are you agree with me?
Forum Responses (Finishing Forum):-
From contributor G:
Hey sir I will say that if you don't want to the scratches to show on the through, you have to fill them to a somehow.
From contributor A:
Sir I will agree with you and I will say that a Sand it all down p600. Use as a glazing and a spot putty to fill the scratches and chips. Sand and prime putty with a metal primer. Spray whole unit with primer surface. Sand p600. Spray can be a finish coat. That's how I'd do it.
From the original questioner:
Thanks. I'd have known exactly how to will be able to handle this job if it was a wood, but I haven't done for the metal for at least twenty-five years. What I didn't forget was how helpful people are here.
From contributor A:
Yeah, didn't want to get too carried away. It's a file cabinet, not a car. ;)
