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.

IMTS 2016: Abrasive Machining, Sawing, Finishing

Booth N-7425: The new, easier to maintain H220HA-DC-C dual column, fully automatic band saw from HE&M Saw uses structural tube columns to create a stouter arm configuration and linear rails to increase arm stability for smoother cutting with greatly improved blade life.
Here are solutions for applications requiring high tolerance and precision surface finish, including grinding technology, sawing and cutoff machines and a variety of finishing systems, such as lapping, balancing, honing and polishing machines. You’ll also find advancements in abrasive size, shape or composite materials, and nano-materials for improved surface finishes in more constrictive areas.

Top of the Line Finishing on Steel, Stainless Steel

The Topcut sanding disc features a formulation of blue Zirconium grain blend that contains a higher concentration of Zirconium, making it the highest performing Zirconium grade disc on the market. The new grain blend is ideal for finishing applications on steel and stainless steel and offers maximized stock removal on any given surface. The disc also guarantees cooler sanding so that the metal will not overheat. The cooler sanding helps to preserve metals, especially the heat-sensitive material, and will result in a beautiful, finished product.
The Topcut sanding disc from Walter Surface Technologies uses a new formulation of blue Zirconium grain blend to remove material 50 percent faster and with a longer lifespan.

Deburring, Edge Blending and Surface Finishing of Hard Materials

Booth N-7163: Diamond Flex-Hone Tools from Brush Research are ideal for deburring, edge blending and surface finishing in hard materials like carbide, ceramic and aerospace steel alloys.
Diamond Flex-Hone Tools from Brush Research Manufacturing use resin bond diamond crystals with high friability that creates self-sharpening edges to provide a quick cut-rate and optimal finish.
