At what speed should my saw blades spin?

Tools Vary Woodworking tools, from table saws to portable saws right down to tiny routers vary in rotational speeds from around 3,000 RPM (Revolutions Per Minute) up to 50,000 RPM. If it is a direct drive motor, the arbor RPM and the blade RMP are the same, which is true of routers and many, but not all woodworking saws. Some table saws are direct drive or have equal sized pulleys. …

How to Double the Speed of Wire EDM | Modern Machine Shop

The biggest part of the speed improvement is simply because a thicker wire can carry more power. A typical 0.010" brass wire will break at higher power levels, which is why standard wire EDM generators typically top out around 30 amps. The 0.016" topas H.E.A.T. wire can take as much as 60 amps without breaking.

Metal Cutting Parameters Basics - Bright Hub Engineering

Spindle speed: Spindle speed is expressed in RPM (revolutions per minute). It is derived based on the cutting speed and the work diameter cut (in case of turning/ boring) or tool diameter (in case of drilling/ milling etc). If V is the cutting speed and D is the diameter of cutting, then Spindle speed N = V /(Pi x D) 4) Depth of cut:

Then, they were used to calculate the resultant milling force (in-plane force) by considering their vector sum. The average resultant milling forces in each experimental case are shown in Fig. 3. As can be seen in Fig. 3, the average resultant milling forces linearly increased with the increase of feed per tooth under the same spindle speed.


The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

GUIDE TO banD sawInG - LENOX Tools

A faster band speed achieves a higher, more desirable shear plane angle and hence more efficient cutting. This is usually stated as FPM (feet per minute) or MPM (meters per minute). Band speed is restricted, however, by the machinabil-ity of the material and how much heat is produced by the cutting action. Too high a band speed or very hard
