Sheet Metal CuttingNotching is a sheet metal cutting process that involves the removal of material from a work piece, starting at the edge and cutting inward. The objective of notching is to create a sheet metal part with a desired profile. Notching is often performed as a progressive process, each operation removing another piece to make the correct contour.
MachiningMachining 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.

Mill Scale Removal question · I'm attempting to remove the mill scale from my welding table top which is 5/8 HRS. I started with Rustex rust converter, which is a phosphoric acid rust converter, with very little success. After a day of repeat appliions, scraping any loosened debris off, followed by some elbow grease and scotchbrite pad, and reappliion of krud cutter rustex, and overnight appliion, I'd barely made ...
Coatings and Fabriion Cleanliness The last three of these specifiions requires all the mill scale, rust, and old paints to be removed. All that can remain on the surface are stains of these contaminants. The following amount of stains is allowed (by visual estimation).
Pickling Steel | American Galvanizers Association · Lowtemperature mill scale consists of two iron oxide layers and develops when steel is heated in an annealing or finishing procedure at less than 1070F. Cracks in either type of scale allow the pickling acid to penetrate the scale layers and dissolve the inner layer, causing the bulk of the scale to be removed in flakes.
Standard Operating Procedure () – Milling Machine | SHOPS · STANDARD OPERATING PROCEDURE ''. Keep all guards in place while operating the machine. While operating the milling machine allow no one else to touch it. Keep hands away from moving cutting tools. Do not make measurements of the stock while the milling machine is powered.
Descaling – Metallurgical ProcessesDescaling – Metallurgical Processes. Descaling is the process of removing oxide deposits from a heated stock, either before or during forging operations. Scales are formed on a metal surface during heat treatment processes. Oxide scales discolor the metal surface and hinder subsequent finishing operations. Descaling is a metal cleaning ...
Vegetable Oil ProcessingFigure is a schematic diagram of the process used to prepare soybeans for the solvent extraction process. The process, which is fairly well standardized, consists of four principal operations: cracking, dehulling/hull removal, conditioning, and flaking. Soybeans are conveyed from the process bins to the mill by means of belts or mass flow
