Cone milling is one of the most common methods of milling in the pharmaceutical, food, chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules.. Generally used for reducing material to a particle size as low as 180µm (80 mesh) a cone mill produces less dust and heat than alternative forms of milling.

When someone uses the term “5-axis” they are typically referring to the ability of a CNC machine to move a part or a tool on five different CNC axes at the same time. 3-axis machining centers move a part in two directions (X and Y), and the tool moves up and down (Z). 5-Axis CNC machining centers can rotate on two additional rotary axes (A and B) which help the cutting tool approach the

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
