The necessary energy for dispersion and grinding is transmitted to the grinding beads by the agitator discs. The mill is fed continuously by the pump. The time spent by the material inside the chamber is controlled by variation of the pump speed. The retention of the grinding beads inside the chamber is achieved by means of a cartridge.

The powder of a material is taken inside the steel container. This powder will be made into nanosize using the ball milling technique. A magnet is placed outside the container to provide the pulling force to the material and this magnetic force increases the milling energy when milling container or chamber rotates the metal balls. 3.

Holes are machined using either a drill bit or an end mill tool. The size of the drill bits is standardized (in metric and imperial units). Reamers and boring tools are used to finish holes that require tight tolerances. For highaccuracy holes with a diameter smaller than 20 mm, using a standard diameter is recommended. Maximum depth

Ball Milling: Ball milling is a grinding technique that uses media to effectively break down pigment agglomerates and aggregates to their primary particles. Using a rotor or disc impeller to create collisions of the grinding media, the impact and force created by the bead mills collisions break down the pigment agglomerates.

The industrial vibratory tumbler machine works on the principle of vibration. Here, the motor makes the bowl vibrate. This vibration of the bowl, in turn, vibrates the tumbling media and the parts inside the bowl. Thus, the media will be rubbing the part continuously for material removal and does the job.

· Because the tool is likely to be small, a fast spindle may be needed to realize this cutting speed range. The use of a ballnose end mill for hard milling of complex die and mold surfaces only makes the need for high speed more likely. When a ballnose tool cuts at light axial depths of cut, the tool does not cut on its full diameter.

First, the machine removes material quickly at a lower accuracy to achieve an approximate geometry. Then, it takes a few higher accuracy passes to produce the final part. If the model has features that can't be reached by the cutting tool in a single setup, then the operator needs to flip the workpiece and repeat these steps.
