Throughfeed vibrators for slide grinding are increasingly gaining importance in many branches. In view of effectivity, they are by all means comparable to normal vibratory finishers, but throughfeed vibrators offer distinct advantages. When applying an appropriate interval feed rate for workpieces, contact-free slide grinding is possible. This process is particularly advantageous for extremely delicate workpieces. A further central property of throughfeed systems is the possibility of integrating existing fully automated production lines.
