Cam Grinder Meets Strict Automotive Standards
The Jucam 1S from Junker specializes in the precise, efficient grinding of cam pieces with minimal downtimes to maximize economical production.
As increasingly stringent carbon emissions regulations are introduced to the automotive industry, compliance with regulations can be achieved with variable engine timing using cam pieces. The Jucam 1S from Junker specializes in the precise, efficient grinding of cam pieces with minimal downtimes to maximize economical production and meet such demand.
The key to the system is a double workhead with two clamping fixtures. It can swivel 180 degrees to a precisely defined end position. The workpiece transfers from its initial loading position to the grinding position using a fully automated process. Concurrently, a second workpiece transitions from the grinding to the discharge position, which drastically reduces downtime.
The non-cylindrical grinding machine also specializes in the efficient package grinding of single cams. When grinding cam pieces, the precise angular reference to the inner toothing is essential. This system clamps the cam pieces with an inner clamping mandrel.
The high quality standards demanded by the automotive industry are met by the intelligent control system, which compensates automatically for material deviations or variables such as fluctuations in temperature. This ensures that all components conform to a constant standard.
The grinder uses cBN wheels for maximum repeat accuracy, extended service life and high stock removal. Depending on the application, the carbon-base grinding wheels possess vibration-damping properties and remain dimensionally stable even at high speeds.
No other process can do what creep-feed grinding can do. Recent tests show even more can be gained by optimizing every element of a creep-feed system.
Real-time-responding CNC brings new possibilities to difficult machining applications.
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.
