Deburring with Black Ceramic Filament Brushes

Burrs differ in size, shape and attachment due to many variables. Nylon abrasive brushes – and black ceramic brushes specifically – can help provide a competitive edge for automotive component manufacturers by increasing throughput when removing burrs and producing higher quality finished parts.
Shops that produce engine blocks, heads, cam shafts and crank shafts for powertrains were once plagued with the challenge of removing burrs created by machining. Not anymore.  

Grinding Gamma Titanium Aluminide

Titanium aluminides possess many characteristics that make them very attractive for high-temperature structural applications in aerospace industries. For example, their high specific strength, high-temperature stability and oxidation resistance relative to conventional titanium and nickel alloys, make them beneficial for use in low-pressure turbine blades for aerospace engines.
New grinding technology is being researched on this intermetallic to help lower the costs of manufacturing aerospace engine components, develop grinding expertise, and design custom-bonded abrasive and superabrasive grinding solutions that are ideal for efficient and damage-free grinding of components made of titanium aluminides.

Documented Cost Savings for Abrasives

Manufacturers usually focus on cost per unit when presenting their abrasive products, rather than on how many total units are used or how those costs can tie up more time in labor-intensive operations. When shops accept the value proposition that time equals money, hard numbers to help them make the best decision can be found in structured documented cost savings programs that compare the abrasive or tooling costs, time, and the labor shop rate related to a variety of abrasive products.
Rather than focusing only on energy savings or reducing costs associated with large equipment, manufacturers that are looking for potential savings in their plants should take the time to investigate just how much money they could save by switching out an abrasive. In doing so, they should evaluate fully how labor costs tie into the equation.

New Weld Brushes Make Flipping Easy

Periodically switching the mounting position of weld cleaning brushes benefits the speed and effectiveness of the brushes, which also improves operator safety. Some newer weld cleaning brushes are designed with a dual-hex nut, to allow for easy flipping of the wheel and elimination of interference issues that pose a safety hazard.
Thanks to new technology that increases wire life and operator safety as the brush wears, flipping your wire brush during surface cleaning has never been easier.  

Common CNC Grinding Mistakes

Because a dull wheel generates more heat and more grinding forces, neither of which are good for productivity or quality, it is more productive to have a finer grit wheel with sharp abrasive grains.
Proper grinding process parameters can eliminate a lot of the “black art” of CNC grinding. One critical variable is the grinding wheel being used and the dressing of the grinding wheel.

Linear Finishing Set for Grinding Jobs

The linear finishing set includes the innovative 5 in diameter POLINOX non-woven PNZ finishing drum that features interleaved layers of non-woven material and abrasive cloth, a selection of POLIVLIES non-woven surface conditioning belts, an aluminum oxide coated abrasive belt, a pneumatic drum holder for belts and a new electric linear finishing tool.
This new linear finishing set from PFERD is ideal for rough stock removal, surface conditioning and consistent, high-quality cosmetic finishing on all metals.

Cut-Off Wheel for Fast and Cool Cutting of All Metals

The premium aluminum oxide grit composition of the VERSA-CUT cut-off wheel makes it highly effective for free cutting on both carbon and stainless steel without bogging down, eliminating the need to store multiple SKUs for different applications. The wheel is also reinforced with fiberglass resinoid to guarantee the safest cut possible.
Built with a 0.045 in cutting edge, the general purpose VERSA-CUT abrasive cut-off wheel from Rex-Cut can be used in almost any cutting application to provide the cutting speed of a thin wheel while maintaining the longevity of thicker options.

Finishing Aluminum

Enduro-Flex 2-in-1 TURBO finishing flap discs from Walter Surface Technologies are ideal for aluminum, stainless steel and steel fabricators needing a one-step surface conditioning solution for weld removal and paint-to-prep finishing.
Enduro-Flex 2-in-1 TURBO finishing flap discs from Walter Surface Technologies use a high-tech blend of self-sharpening grains and cooling agents for ultra-high removal and blending rates without causing surface discoloration on steel, stainless steel and aluminum.
