The No-toolchange Cold Roll Forming Machine BURS21

Your productivity will be improved dramatically with this time & cost-saving machine requiring less tool changes and no skilled engineers.




Conventionally, cold roll forming machines require you to;

1. purchase several sets of tools called “forming rolls” (one set for one product) and store them in your workplace,

2. replace the entire set of rolls at a changeover for different products, and

3. have experienced workers to adjust these changed rolls.

Our newly introducing No-toolchange Cold Roll Forming Machine BURS21 offers you a solution to these problems by (1) providing you with our newly developed roll set that can be used commonly for several products and (2) roll positioning NC system using screw mechanism with servo motors.

This innovation has reduced the tool change man-hour almost to zero and nearly doubled the productivity. This is the world first real time & cost-saving cold roll forming machine.
