Vollmer’s VGrind 360E Overcomes Bearing Problems with Vertical Spindle Alignment
Westec 2019: Vollmer’s VGrind 360E has two vertically configured grinding spindles.
Vollmer’s VGrind 360E five-axis CNC grinding machine has two vertically configured grinding spindles. It is designed with short linear-axis travel distances and swivel ranges for increased efficiency and precision in production. The two grinding spindles are situated one above the other, with a grinding wheel set positioned in the X-axis pivot point. The VGrind’s polymer concrete walls increase rigidity.
The VGrind’s vertical spindle arrangement is said to solve problems related to fixed and floating bearings. Both grinding spindles can be fitted with various tools. Its motor and spindle cooling concept is said to provide higher thermal stability and lasting power and precision.
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.
Advanced grinding equipment gives this shop the flexibility and automation it needs to serve customers with either rapid-response or high-volume jobs.
Achieving consistent and quality results from the centerless grinding process requires an understanding of the basic fundamentals. Most application problems associated with centerless grinding derive from a misunderstanding of the basics. This article explains why the centerless process works and how to use it most effectively in your shop.
