Practical notes on polishing, abrasives, workshop processes and product selection from a manufacturing perspective.
Flap discs all look similar on a shelf, but the backing, the flap layout and the abrasive grain decide whether a disc blends a weld cleanly or just makes heat. This guide separates the variables so you can specify a disc from the workpiece backwards. Backing: what the plate does The backing controls support and […]
Ask three polishers which compound colour means what and you will get three answers. Colour is a useful way to keep bars and wheels apart on the bench, but it is not a universal grade standard. What actually matters is the sequence: a cutting stage to remove the scratch pattern, then a colouring stage to […]
Every polishing job has places a big wheel cannot reach: corners, slots, threads, engraving, jewellery findings, die cavities, the inside of a tube. Pen brushes and mini mounted wheels exist for exactly that. They run on a 2.35mm or 3mm shank in a rotary tool, and choosing between them comes down to three numbers — […]
Most cotton buffing wheels carry a simple stamp — a number, a multiplication sign, another number. That mark tells you the diameter and how many layers of cloth the wheel is built from, and those two numbers explain almost everything about how the wheel will behave. This guide shows how to read it and how […]
A connected workflow for cutting, surface preparation, polishing and inspection in an industrial finishing process.
Why the polishing compound, buffing wheel and finishing stage must be selected as one working system.
Understand how grit, disc profile and the next process step affect flap disc selection for grinding and surface preparation.
A practical way to select cotton cloth construction, flexibility and polishing compound for the workpiece and finish you need.
