External grinding of pipes: wet or dry? DRY grinding stainless steel pipes produces tarnishing. This is not just an aesthetic problem; it also increases the risk of corrosion. Pipes then have to be reworked in a time-consuming process. Tarnishing is caused by the heat that builds up during dry grinding. The heat triggers oxidisation processes in the material, which become visible as tarnishing. In contrast, wet

For tradesmen, wet grinding delivers added safety and comfort when working. Swarf is bound in the coolant, so dust pollution in the workshop is low. A closed coolant circuit reduces coolant consumption and makes eco-friendly disposal easier. Cool grinding equipment is worth considering for stainless steel processing workshops, particularly for those in handrail production, plant or tank construction, and classic metalworking activities. Modular belt grinding systems, such as those offered by Fein under the Grit by Fein brand, offer an alternative to purchasing a complete wet grinding system. They allow the addition of a cooling lubricant module, which can be mounted tool-free if necessary. Fein develops and produces application solutions for the metalworking, interior outfitting and automotive sectors, and is a specialist in power tools for industry and manual trades. The company holds more than 800 active industrial property rights, including around 500 patents and patent applications. Fein markets its products through 19 international subsidiaries and more than 50 representations around the world. Fein Industrial Power Tools UK Ltd – UK

grinding delivers good grinding results, without the need for time- consuming rework. Wet grinding involves applying cooling lubricant directly to the machined material, so that no or very little heat builds up during grinding, and no tarnishing develops. Wet grinding is recommended for all stages of work, from coarse grinding to surface finishing. Although wet or cool grinding achieves better results, smaller companies in particular are reluctant to invest in cool grinding equipment. The investment can be worthwhile, even for small amounts of work. In addition to the cost savings resulting from the high work quality, wet grinding is also kinder to the grinding belts, lengthening their service life.

or square up stock at 90°. An extra long mounting slot allows for adjustable mounting, and can easily accommodate two mounting bolts for greater stability. BuildPro clamps can be inserted into the mounting holes on the two side walls or the top surface of the clamping squares for vertical or horizontal hold down clamping.
