10 Milling Toolpaths for Your First 2D CNC Machining ...

· CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically egorized as 2D, 3D, 4axis, and 5axis. However, the term 2D is a bit misleading since this toolpath uses the Zaxis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.

Homogenizer: What Is It? How Does It Work? Uses, Types Of

Colloid Mill: A colloid mill is a homogenizer composed of a conical rotor and stator. The rotor and the stator are separated by a small clearance where the premix will flow due to shear and centrifugal forces. As the premix is gravimetrically fed into the rotorstator assembly by a hopper, it is thrown outward towards the exit slot or holes.

Ball Mill

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
