Tungsten Carbide Reamer ⅩⅤ

Details: Category: Tungsten Information; Published on Wednesday, 28 October 2015 18:15

In part 14 we know that versus high-speed steel reamers, tungsten carbide reamers are more expensive, but are can be applied to ream hardened materials with a longer life because of its much greater hardness. And here we explain shortly the work piece materials and lubrication during reaming process.

Work piece materials

Aluminum and brass are typical work pieces with good to excellent machinability ratings. Cast iron, mild steel and plastic have good ratings. Stainless steel has a poor rating because of its toughness and it tends to work harden as it is machined.

Lubrication

During the process of reaming friction causes the part and the tool to heat up. Proper lubrication cools the tool, which increases the life of the tool. Another benefit of lubrication includes higher cutting speeds. This decreases production times. Lubrication also removes chips and contributes to a better work piece finish. Mineral oils, synthetic oils, and water-soluble oils are used for lubrication and applied by flooding or spraying. In the case of some materials only cold air is needed to cool the work piece. This is applied by air jet or vortex tube.
