Jun 09, 2021 · Grab that carbide grinder if you can. You can get white plate wheels for them that make grinding HSS easier esp for thread cutting etc. The Super7 you have has a clutch. It’s a good small lathe but not rigid enough to use over 3/4hp. And with a clutch is easy to start even at high speed settings. The belts are easily available in USA.

In the area of thin plate cutting, traditional CO 2 laser and YAG laser is gradually occupied by fiber laser generator, mainly for the following reasons:. ⑴ Low cost. The photoelectric conversion efficiency of the fiber laser is about 30%, the photoelectric conversion efficiency of the CO 2 laser is 6~10%, and the photoelectric conversion efficiency of YAG laser is only 3%.

How many axes of motion does a plasma cutting machine use?
The headstock (H1) houses the main spindle (H4), speed change mechanism (H2, H3), and change gears (H10).The headstock is required to be made as robust as possible due to the cutting forces involved, which can distort a lightly built housing, and induce harmonic vibrations that will transfer through to the workpiece, reducing the quality of the finished workpiece.

Cutting Speeds & RPM Calculations
Conversion to an 0.045” (1.2 mm) EC409Cb metal cored wire welded under pulse conditions at 190 amps, 21 volts and 27.5 inches per minute travel feed speed. Not only did the travel speeds increase, but an additional advantage was seen in the ability of the metal cored wire to bridge gaps due to poor fit up.

Important considerations for use of the plasma process. Cut Speed. Often measured in inches per minute, this is the speed the torch travels at during the cutting process. Plasma is typically the fastest process for cutting the common material types. Cost Per Foot. Cost per foot cut is a common tool used for calculating the cost of a cut part.
