- In 1988, Diabrasive Int’l (now a part of Abrasive Technology) introduced diamond to the sueding industry at a large trade show in Germany. Torres, a Spanish textile machine manfacturer, devised a small machine that outperformed the much larger machines commonly used in the trade, simply because it was fitted with damonds instead of regular abrasives. The market took notice.Textiles are sueded, or abraded, or sanded to give the fabric a pleasing-to-the-touch peach skin finish. Most textiles are abraded in some manner, whether for bedding sheets, pants, shirts or underwear. Even upholstered material receives the treatment. And most recently, swimwear and laced feminine lingerie have become the latest products for suediing. For the most part, fashion dictates the finish and fall lines typically make more use of sueded techniques over lighter summer wear.
Sueding machines are typically made with rollers on which abrasive sheets are fixed, and the textile is forced in contact against the rollers to produce an abraded finish, more gentle to the touch. There are many configurations of machines and Continuum readily adapts to a great majority. When rollers are equipped with sandpaper, sueding work needs continuous attention from the operator to ensure an even finish, as the abrasive wears. This is because textiles are extremely abrasive and as such place a big demand on the abrasive surfaces requiring very frequent adjustments, and replacements. A roller change, typically every 4 hours or less of operation, causes major downtime as production is halted during the changeover.
When the abrasive on rollers is replaced with diamonds, they last much longer – typically millions of meters. At a speed of 10 meters per minute, a machine will work continuously for months, 24/7, without interruption. Downtime due to abrasive changes is eliminated, production increases and more importantly, the fabric has exactly the same finish characteristics, all with minimal operator intervention,from the beginning to the end of each run.
An traditional sandpaper strip costs much less than Continuum strips. Fortunately, the return on investment is easy to calculate for shop managers who readily see the benefits on their productivity. And for managers and owners, we developped calculators to assist them in calculating their savings.
To install our diamond strips onto machinery, we simply wind a long strip of Continuum helicoidally onto the entire surface on the drum and fasten it firmly at both ends. Previous products were produced by joining individual strips together, but in high humidity and heat (think monsoon) conditions prevalent in Asia, the joints could come apart. Hence, we eliminated the joints and created Continuum.
We’re proud Continuum promotes AT as a company that provides the very best tools for a specialized and demanding industry.
Abrasive Technology is pleased to announce it has applied for a provisional patent for a CMP (chemical mechanical planarization) pad conditioning method designed to provide users with increased tool utilization and cost savings.
The provisional patent describes a method where a separate CMP pad conditioning disk is used specifically for the CMP pad break-in process.
Traditionally, a single CMP pad conditioning disk was used for both the break- in process and the “in process” conditioning, which has resulted in longer pad break-in times because the “in process” CMP conditioner was not optimally suited to match the needs or requirements to break in a new CMP pad.
Additionally, since the disks often have enough life to condition more than one pad, consistency on subsequent pads during the break in and manufacturing process varies because of the degradation of the conditioner throughout its lifetime.
By utilizing two separate disks (one for the break-in process and one for “in process” conditioning), users can expect one or more of the following benefits:
– Increased CMP tool utilization (reducing CMP pad break-in times).
– Increased current CMP pad and “in process” CMP conditioner lifetime.
– Improved process stability.
– Improved CMP module cost (improved pad life, improved conditioner life, reduced tool downtime, and reduced pad break-in failure rates result in increased tool utilization).
– Capability to customize new CMP pad break-in conditioning disks to the pad type and material specified by the customer.

On the final day of Inventor’s Month, we have one last associate to celebrate. After seeing the devastation caused by the 2010 earthquake in Haiti, Josh Dudley decided to develop the ultimate too for rescue workers. The result was Jack of All Blades, a unique, emergency circular-saw blade that cuts metal, wood and masonry.
Josh and his fellow engineers at Abrasive Technology have ingenuity in their DNA. Abrasive Technology focuses on producing the best superabrasive grinding wheels and tools available, with a culture built around findng creative ways to solve problems for customers.
April is Inventors Month, so we’re celebrating one of our favorites, Butch Peterman, president and co-founder of Abrasive Technology. Under Butch’s leadership, AT invented and patented the process for brazing diamond to steel (P.B.S.® bond), used today in a broad spectrum of industries and markets. Personally, Butch has earned other patents and patent applications in the areas of gear grinding, electronics and superabrasive wheel manufacturing.

1.) Know your wheel speed: wheel speeds on machines vary and the most successful ceramic grinding operations are performed between 5500 & 6500 SFPM.
2.) Condition the wheel properly: Aluminum oxide dressing wheels produce the most open structure along the face of the grinding surface. A clean grinding surface is essential to successful ceramic grinding.
3.) Dress frequently: dressing the diamond wheel frequently provides a clean grinding surface and prevents the fine ceramic swarf from becoming trapped between the diamond particles.
4.) Ceramic is a tough material: Expect grinding pressure when grinding ceramic materials. It is also an insulator material which means that heat generated during the grind process is absorbed into the grinding surface.
5.) Follow the first four steps: You will find a greatly improved ceramic grinding process requiring little to no spark grind to produce a clean chip free edge.
