what is secondary milling in the milling circuit

What is Carbide?

The machine used for milling is called a milling machine. 3. DRILLING. The photo on the right is a tool that produces circular holes in workpieces and is called a drill. Indexable insert type drills and brazed drills produce relatively large holes and solid drills produce smaller holes. The main characteristic of drilling is that it can be used Get price

Our modern vertical roller mill takes you further

This allows standardisation of the mill's mechanical parts, along with the use of the same construction procedure. Replacing the steel with concrete also minimises vibration in the foundation. A simple layout with fewer machines in the mill circuit and eliminating the need to transport steel stand parts helps keep civil construction costs low. Get price

Machining

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams. Get price

Printed circuit board milling

Printed circuit board milling (also: isolation milling) is the process of removing areas of copper from a sheet of printed circuit board material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.
