Surface Finishing & Coating

Whether traditional or new manufacturing processes are involved, none of the available technologies make it possible to produce component surface finishes in the required quality. Process steps such as deburring, rounding and cleaning, as well as targeted functional or decorative surface finishing, are thus indispensable. Solutions by means of which these tasks can be executed reliably and economically will be presented at DeburringEXPO at the Karlsruhe Exhibition Centre from Oct. 8-10, 2019. Beyond this, the third leading trade fair for deburring technology and precision surface finishing will provide valuable know-how at its bilingual expert forum.

If you read the online forums, it is immediately clear that identifying the optimal technique for removing the inevitable burrs created during machining of threaded parts is the subject of much debate.

Microfinishing can make a high-quality gear even better by reducing surface roughness.

Anodizing is an economical approach to resolving surface finishing challenges.

EXAIR says its new Soft Grip Back Blow Safety Air Gun uses the smallest back blow nozzle available to deliver a blast of air to effectively blow debris and liquids from inside small pipe or hose diameters, channels, bores, holes, internal threads and other internal part features. The ergonomic design of the air gun keeps the operator's hand in a comfortable position so it can be used for hours of continuous use without fatigue.

Formulators looking to enhance the corrosion protection of increasingly popular water-based coatings systems can now use Cortec's M-120, a water-based corrosion inhibitor additive that does not contain heavy metals. M-120 can be used alone or in conjunction with other inhibitors to increase the corrosion protection abilities of both water-based and solvent-based systems. It is recommended for use in acrylic and alkyd resin systems.

Whether they're required for downstream manufacturing steps or for error-free functioning, surface characteristics are decisive with regard to part and product quality. Processes such as deburring and precision surface finishing are becoming more and more significant as a result – regardless of whether the parts are produced by means of erosion, forming, primary forming or additive manufacturing. DeburringEXPO, the world's only trade fair that deals exclusively with the removal of burrs and the production of precision surface finishes, will be held at the Karlsruhe Exhibition Centre from Oct. 8-10, 2019.

EXAIR's new Gen4 Super Ion Air Wipe provides a uniform 360 degree ionized airstream that clamps around a continuously moving part to eliminate static electricity and contaminants. It is suitable for removing dust, particulates and personnel shocks on pipe, cable, extruded shapes, hose, wire and more.

As part of its ongoing commitment to empower organizations to create safer work environments and comply with OSHA standards, Rockford Systems LLC has introduced an automatic sanding belt holder that enables lathe operators to sand, polish and deburr while keeping hands away from rotating parts and at safe operating distance away from the spinning shaft and, thereby, helping to prevent entanglement.
