2009年10月6日 · The optimum shape depends upon Durometer (hardness) of the rubber and finish desired. For simple truing of the surface as you are doing, it is easier with a belt grinder mounted to the compound. Regards, Clark

2010年2月14日 · That can be particularly handy if one must use a non-grinding machine such as a lathe for the job. An ordinary freezer isn't good enough, machining it in its unfrozen state is a pain, but one thing about rubber is that it grinds very well, surface grinding or cylindrical grinding is the way to go, quick removal rates, and good surface finishes.

just wanted to share a video of a protype lathe tool to cut rubber on a lathe

It's different, but not as much as you'd think. Turning rubber on a lathe is doable.

2009年4月27日 · Hi guys, what is the best option to cut rubber on a lathe? Its basically a dome shaped piece that needs a 2" flat surface put on. I would like to use my standard DNMG style insert but what geometry/grade etc is best for rubber?

2023年12月2日 · Success in machining rubber depends greatly on the durometer of the rubber. A hard rubber like a hockey puck machines fairly well but softer rubbers are almost impossible to machine. Generally, the colder the rubber is, the easier it is to machine. Razor sharp tools with a high rake will help.

2006年1月11日 · I am tasked with reducing the diameter of some rubber coated nip rolls for my business. Normally these would be ground, I think, but I only have a lathe to work with, and the surface finish is not terribly important. I have ground a high speed steel tool with a good deal of rake and a round nose.

As the video shows - hollow ground relief on the finishing tool is key. Loved the roughing tool - brilliant! interesting.Can you cut rubber with a carbide tool?

Lathe-cutting rubber is an efficient, affordable choice to produce quality parts, especially for uses where a static seal is needed. The process of machining rubber on a lathe to create products, such as gaskets, washers, and seals, is similar to any lathing method where the material to be worked is mounted on the lathe shaft and precision cut ...

2010年9月16日 · Rubber grinds quite well, but it does stink up the place and makes a mess. Other than that, you can use a fine stone and get a pretty decent finish. I think the trick with rubber is to have the cutting edges skimming it at a very high speed, so the inertia of the rubber molecules keeps it in place as each cutting edge removes the smallest bit ...
