Servo drive systems are of particular interest in the field of automated assembly of intermittent cam indexers. The flexibility and programmability of such a system is beneficial to the operation of the overall system, especially in processes where the machining cycle is short and the various machining operations are mixed. However, a cam indexer system with intermittent function is still a better approach if it is considered in terms of operating speed, stability and cost.
On the one hand, the drive system of the cam indexer has many advantages. They are reliable, durable and easy to operate. For systems driven by cams, you only need to calculate how many stations you need (determine the number of stops) and the time required to run (machining and dwell time), then effectively design the cams according to your needs, using servo drive systems. A control engineer is required to plan acceleration, deceleration, speed, and other parameters. The cam drive system only needs to provide: control acceleration and deceleration, accurate repeat positioning. High-load running capacity, and smooth motility. In the operation of the cam indexer,
The indexer's stop is a fixed program. Low cost maintenance and superior performance are among the benefits of cam split drive. It is also easy to do when the cam indexer requires maintenance.
Compared to the servo drive system, the cam indexer also has an advantage in terms of life and maintenance. If you compare the mechanical life and the electronic servo, no matter from the application experience or the historical analysis, a servo motor is less than ten years, and the cam indexer has been used for more than ten years. In terms of mechanical performance, the equipment is strictly maintained and maintained according to the requirements of the components, and the service life is also greatly enhanced.
