(1) Compared with ferromagnetic minerals, the value of the specific magnetic susceptibility of weak magnetic minerals is much smaller and does not change with the change of external magnetic field strength.

(2) There is no residual magnetism in weak magnetic minerals.

(3) The magnetic properties of pure weak magnetic minerals are very weak, but if a small amount of ferromagnetic minerals are mixed therein, its magnetic properties will change greatly. Artifacts are e.g. hematite weakly magnetic minerals, if it remains in the interior of a small amount of magnetite, it will greatly enhance magnetic. This should be especially noted when selecting weak magnetic minerals, especially for selection.

Cnc Milling features:

1, parts processing adaptability, flexibility, can process the shape of the contour is particularly complex or difficult to control the size of parts, such as mold parts, shell parts, etc.;
2. Able to process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curve parts described by mathematical models and three-dimensional curved surface parts;
3. Parts that need to be processed in multiple processes after processing once clamping and positioning;
4, high machining accuracy, machining quality is stable and reliable, the pulse equivalent of CNC device is generally 0.001mm, high precision CNC system up to 0.1 m, in addition, Cnc Machining also avoid operator error;
5. High degree of production automation can reduce the labor intensity of operators.
It is beneficial to the automation of production management.
6, high production efficiency, CNC milling machine generally do not need to use special fixture and other special process equipment, in the replacement of the workpiece only need to call stored in the CNC device processing procedures, clamping tools and tool data can be adjusted, thus greatly shorten the production cycle.
Secondly, CNC milling machine with milling machine, boring machine, drilling machine function, so that the process is highly concentrated, greatly improve the production efficiency.
In addition, CNC milling machine spindle speed and feed speed are infinitely variable, so is conducive to the selection of the best cutting parameters
