Mainly used for pressure die casting. Similar to LM 6 but with better machinability and hardness. LM 21: Generally similar to LM 4M in character and application but better machinability and proof strength. LM 22: Used for chill castings requiring good foundry characteristics and good ductility. Requires heat treatment. LM 24 I find the machinability ratings listed in the usual places to be not what I experience. Example would be 7075 lower than 6061. To me, 7075 machines just as nice if not better than some of the lower yield aluminum alloys.

The machinability of steel The castability of steel The formability of steel The hardenability of steel and how it is measured The weldability of various types of steel; Figure 1. Steel pipes in different forms. Machinability of Steel. Machinability is defined as the ease with which a metal can be machined. Since machining centers don’t have gas pedals (nor gages that announce the current cutting speed), spindle rpm is the value we have to plug into the CNC program. To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter.

Customer Benefits of Cold Drawn Steel Bars and Steel Wire Cold Drawn Steel Product Features / Customer Benefits. Improved Size and Section / Reduces machining losses . Tighter size & section tolerances ; Dimensional consistency within each bar ; Dimensional consistency from bar to bar Free machining steel is steel that forms small chips when machined. This increases the machinability of the material by breaking the chips into small pieces, thus avoiding entanglement in the machinery. This enables automatic equipment to run without human interaction. Free machining steel with lead also allow for higher machining rates.

A typical drill press often has an RPM limitation of between 2000-3600 RPM. If the chart above specifies a higher RPM than your machine is capable of, it should not cause a problem to run at a lower RPM. For instance, many people drill 1/16″ holes at less than 10,000 RPM with no problems. Machining stainless steel on a hobby CNC? I am comfortable cutting aluminum all day long on my machine, but would like to try cutting some stainless steel or tool steel. I know a few folks have done it, just wondering what has worked, in terms of feed/speed, DOC, and with what tools? Steel is by far the most popular material in machine shops. Machinability of Steel ranges from free-cutting materials like 12L14, with a machinability of 170%, and up to challenging tool steels such as D3 or O1 with Machinability of 30-40%. We will break down this big family of materials into sub-groups and discuss the machinability of each one.
