Innovative solutions for eeducing cycle times and downtimes
The machinery system comes with numerous devices that are designed to assist the operator in the process of using it, ensuring excellent availability coupled with low operating costs.
Not only that, but the high-performance automatic dressing system also reduces downtimes. Thanks to the position of the dressing unit on the right-hand side, only minor soiling occurs during the dressing process. The extraction channel, meanwhile, is located in a place that makes it possible to extract grinding wheel dust as soon as it appears.
The rigid design of the dressing slide ensures that a consistently high level of dressing quality is maintained throughout the entire stroke.
Even dressing at an angle is possible thanks to the control concept based on 2 servoaxes. The software package required for this is available to order as a separate option. In most cases, grinding wheels used in a dressing process are positioned so that they are parallel to one another (known as the down-feed grinding technique).
However, this can result in springs in the outermost row of the loading plate being ground to a shorter length than springs that are positioned further toward the inside. The reason for this lies in the shorter grinding path that the springs on the inside of the loading plate experience (in other words, a smaller radius). Positioning either one grinding wheel or both at an angle, so that the distance between the grinding wheels at the central point is 1-3 mm larger, solves this problem as the lower contact pressure exerted during grinding compensates for the longer path that the outer springs experience.
Another feature designed to help the operator is the viewing window in the protective hood, which makes it easier to perform visual monitoring of the grinding process.
The extraction and ventilation concept, with an extraction channel installed in the perfect position, is a crucial part of what makes the machine's availability so good. It is positioned as far as possible toward the front, directly behind the dressing system, and tangentially to the grinding wheel in order to prevent deposits in the grinding room as far as possible.
The design of the grinding room itself features optimized flow characteristics and ensures that the extraction volume is kept even at all times. Two fans generate an air shower for actively cooling the grinding room during the grinding process, making it possible to take advantage of maximum speeds while at the same time reducing deposits.
