Time-saving and Flexible: Collet Adapter is a Smart Investment
The GDS µGrind collet adaptor from ANCA Inc. (Wixom, MI) is designed with the highest level of consistent accuracy and improved productivity in mind. The performance of any process relies on the performance of its individual components. This is particularly relevant in the grinding of precision tools. The increasing need for extreme accuracy and tolerances, as well as competitive and labor pressures, result in the demand for accessories that are more precise, easy to use and maintenance free.
A selection of good quality, easy to use workholding that provides minimal and consistent runout is one of the prerequisites for successful grinding, resulting in quality tools and happy customers – once again reinforcing that the quality of the whole process relies on the quality of all its components.
ANCA has partnered with GDS, a renowned German manufacturer of high-quality precision accessories for grinding and machining processes. One of their flagship products is the µGrind workholding, which is now available from ANCA’s distribution network. The µGrind has been customized to suit the requirements of ANCA grinding machines and can be set up in a matter of minutes.
Benefits of the µGrind workholding:
- Time saving: Thanks to minimal and consistent 2um runout, which provides consistency over large batches and collet changes.
- Easy and fast setup: It only takes minutes to get the µGrind ready for grinding and readjustment between collet changes is not needed. Concentricity and wobble adjustments are easy to perform.
- Flexible: A suite of compatible collets with form factors to suit almost all applications is available. µGrind comes in two form factors (standard and long nose) to suit almost all applications.
µGrind performance has been tested in real-life applications and the results are very consistent. A test was performed over a large batch of 6 mm tools where runout was measured before and after grinding at 2.5 x Ø and 10 x Ø. Even with thousands of clamping and diameter changes, the runout remained virtually unchanged.

Three Exclusive new Technologies Maximize the Life of Ceramic Abrasives
In its quest to become a global leader for productivity and safety solutions in the metalworking industry, WALTER Surface Technologies (Windsor, CT) has launched three exclusive new technologies to further maximize life of its high-performance ceramic abrasives.
“Ceramic grains provide longer life, higher removal rates and improve comfort for operators,” said Marc Brunet Gagné, senior product manager, abrasive power tools. “But it takes more than just the grain to build a high-performance abrasive wheel. WALTER has gone beyond the grain with new exclusive technologies to ensure that the ceramic grain is optimized and performs at its best.”
WALTER’s exclusive SMART RESIN™ Technology, found in bonded abrasives such as the ZIP™ XX and the XCAVATOR XX™, works to expose fresh ceramic grains at the optimal moment to achieve the most productive balance between sharpness and life in a metalworker’s given application.
WALTER’s exclusive V-STRONG™ Backing Technology, found in its ceramic sanding discs such as the XTRACUT™ and the COOLCUT XX™, improves durability and toughness of the wheel thanks to stronger resistance of the cloth. “With 14% more vulcanized fiber in the cloth than competitors, WALTER ceramic sanding discs last longer, resulting in less wheel changeover.”
“Most flap discs are baked during the manufacturing process to bond the flaps to the backing,” continued Brunet Gagné. “Unfortunately, this process can dry out the backing cloth of the flaps, reducing its performance.” Now, thanks to WALTER’s exclusive MAX LIFE™ cold curing glue, the freshest abrasives possible are available on products such as the ENDURO-FLEX™ TURBO, to avoid micro-cracking and drying out, which improves consistency, and can extend disc life by up to 25%.
