Grinding (Surface, Cylindrical, Tool & Cutter)

The wheels feature an innovative Norton Quantum Prime nano-crystalline ceramic grain, embedded in an optimized matrix of Norton Vitrium3 bond. The combination of the micro-fracture properties of the new ceramic grain from Saint-Gobain Abrasives and the retention capability of the bond ensures long wheel life, excellent grinding efficiency, and consistent part quality with superior finish which results in cost savings of 30% and more.

Company turns to United Grinding for a machine that has both grinding and EDMing capabilities.n

The Grinding Doc lists to-do items for improving 'ugly' grinding process.

The ShapeSmart model NP50 is a five-axis "pinch/peel" grinding machine from Rollomatic that features unique technology for turning out nonround parts.

New opportunities are expected with the new investment in the company.

Norton Quantum Prime Wheels have several important advantages including a new micro-fracturing grain that has unparalleled sharpness and cutting efficiency which reduces power draw and cycle times, while increasing material removal rates. The unique grain is free cutting, which combined with advanced bond technologies such as Norton Vitrium3, allows Quantum Prime to wear more consistently, improving part quality, geometry and finish even at high material removal rates.

Glebar pairs the wider work wheel with an oscillating regulating wheel powered by servo motors to reduce setup time and improve sphericity. The slides can be programmed to finite positions through a touchscreen HMI. When an operator selects a job, the servo motors automatically adjust to programmed positions which reduces setup time.

The Weifuautocam Precision Machinery Corporation from Wuxi, China is using a Grindstar profile and cut-off machine from Junker for the production of adjusting screws for high-pressure hydraulic pumps. Weifuautocam, a part of the Weifu Group, began collaborating with Junker in 2000.

Advice is given for switching from conventional vitrified grinding wheels to vitrified CBN when cylindrical grinding.

The Grinding Doc says there are four factors to consider: stiffness, cycle time, chatter and alignment

At The Grinding Doc, we put together this short video with some of our more popular electron-microscope photos. Take a look. It might just change how you see grinding.

Jeffrey Badger, Ph.D., discusses the grinding principles at work that cause chatter in the 106th episode of The Grinding Doc video series.
