Hand operated force driven tool i.e. welding point miller, for opening laser pricked seams at overlapping units of vehicle body parts, has guiding wheel comprising rib that rotates in circumferential direction and runs down into crown

摘要

The tool (1) has a rotary drive source (2) comprising a chuck (9) for holding a miller (12). The miller is rotary displaced regarding to a rotation axis of the miller, by the rotary drive source. A guiding wheel (17), whose rotation axis is aligned rectangular to the rotation axis of the miller. The guiding wheel comprises a single rib that rotates in a circumferential direction. The rib runs down into an exact edged crown. The guiding wheel is found between the miller and the rotary drive source. The rotary drive source is designed as compressed air motor or electrical motor.
