Assuming you're not casting, and working with a commonly machinable material, external corners would typically be rounded over using a tool called a 'radius cutter' or more formally, a 'corner rounding end mill.' A particular cutter only cuts one radius, so if you have two fillet radii, you'd need a tool change.
The Planetary Ball Mill PM 100 is a powerful benchtop model with a single grinding station and an easy-to-use counterweight which compensates masses up to 8 kg. It allows for grinding up to 220 ml sample material …
7. The ball mill is used for grinding materials such as coal,pigments,and fedspar for pottery. Grinding can be carried out in either wet or dry but the former is carried out at low speeds. The advantages of wet grinding are less power consumption,increased capacity,no dust formation etc…. Dis advantages are high wear on the grinding medium ...
The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. The critical speed (rpm) is given by: nC = 42.29/√d, where d is the internal diameter in metres.
This approach is based on a hybrid numerical model of a 24-degree-of-freedom gearbox, simulating one gear train and two drive shafts. The impact forces of the mill drum are modelled by a discrete element method (DEM). The ball-filling rate (Fr), the mill speed (Nr), and the ball size (Db) are considered to study this phenomenon.
Our ball mills are industrial grade and designed for continuous operation, equipped with oversize roller bearings and a complete drive system. All wear parts are highly abrasion …

To start cutting the internal thread, you first center with a punch and then drill a core hole using a twist drill. To make a chamfer into the core hole, use the 90-degree countersink. Cutting the thread involves turning the tap wrench into the core hole with the tap attached. 2. How to Cut an External Thread.
Mill cylinders are typically supplied with a cooling jacket on their cylindrical portion for temperature control, especially when processing …
Principle. Ball mill principle work on Impact and Attrition. Both are responsible for size reduction, rapidly moving balls are used for reducing the size of brittle materials. Impact: Impact mean pressure exerted by two heavy objects. Attrition: Reduced the size of the materials when they colloid by heavy weight (Ball).

Figure 1 illustrates the internal helical milling process with a ball-end mill that can machine undercuts. ({R}_{i}) stands for the radius of the initial hole. The model considers a fixed reference plane that passes through the axis of the hole to observe the swept area of the tool in this section. The ball-end mill can be modeled as a sphere.
