When do you stop using the tool and then grind it?

One auto parts manufacturer sends taps for repairs every 2,000 to 3,000 holes it processes. In this way, each tap can be reused three times. But if he uses the taps until they are completely damaged and then sends them back for repair, they may only be able to process 1,000 more. We recommend that […]

Some problems that must not be neglected in tool grinding

Tool materials Common tool materials in tool grinding are: high speed steel, powder metallurgy high speed steel, hard alloy and PCD, CBN, cermet and other superhard materials. High speed steel tool sharp, good toughness; Carbide cutting tools have high hardness but poor toughness. The density of carbide tool is obviously higher than that of HSS […]

Coating and grinding technology of tools

In the regrinding process of the drill bit or milling cutter, cutting lip should be ground to remove the original coating, so the grinding wheel used must be of sufficient hardness. Regrinding pretreatment of cutting lip is crucial, not only to ensure that the geometric shape of the original cutting lip after regrinding can be […]

You need to know the alloy milling cutter before grinding

The alloy milling cutter is a tool with high hardness, high bending strength and toughness. Its hardness value varies with the nature, quantity, particle size of carbide and the content of metal bonding phase, and generally decreases with the increase of the content of bonding metal phase. Alloy milling cutter is suitable for processing copper, […]
