The miniature ball mill is a smallsized mill that is used to grind various materials. It is widely used in the laboratory and smallscale production because of its low cost, ease of use, and small size. The miniature ball mill consists of a cylindrical vessel, which is mounted on a stand and rotated by a motor.
Therefore, in order to exert the microgrinding function of CBN particles, a mm diameter PCBN micro ballend mill is designed with a spherical flank structure (MSPBM) as shown in Fig. 1. This mill has five cutting edges, and the spherical flank structure makes each cutting edge have a 0° relief angle. This.

where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
Micro or miniature end mills are small diameter end mills with an 1/8" or 3mm shank diameter, where the cutting diameter is usually smaller. They are true mini end mill bits!
