Grinding Machine Designed for Single-Part, Series Production
IMTS 2018: The Studer Favorit CNC cylindrical grinding machine, available through United Grinding, handles long workpieces and has a center distance of 1,600 mm (63").
The Studer Favorit CNC cylindrical grinding machine, available through United Grinding, handles long workpieces and has a center distance of 1,600 mm (63"). The machine is designed for grinding single parts as well as for series production, and it can be fitted with automation. Options include measuring control, a balancing system, contact detection and longitudinal positioning for other grinding tasks.
The machine bed is made of solid Granitan, which enhances precision, performance and safety. The full enclosure is said to provide an optimal view of the grinding process. The wheelhead, which can be automatically positioned every 3 degrees, accommodates a belt-driven external and internal grinding spindle.
The company’s grinding software is said to enable users with little experience to program grinding and dressing cycles quickly and efficiently. Optional StuderGrind software enables efficient programming of special applications such as profiling the grinding wheel for complex workpiece shapes.
Advanced grinding equipment gives this shop the flexibility and automation it needs to serve customers with either rapid-response or high-volume jobs.
It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.
Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
