BRC-Series

Motorless rotary punch from Baust for roll forming systems

The BRC punch insert from Baust operates entirely without its own motor, instead utilizing the kinetic energy of the passing strip material. This fully mechanical design eliminates the need for additional electric drives and significantly reduces maintenance requirements. The abbreviation BRC stands for Coil Driven Punch and accurately describes the operating principle of this motorless rotary punch.

We have been developing punching technology for industrial applications for decades and, with the BRC series, have created a solution that fits seamlessly into existing roll forming lines. The motorless rotary punch is particularly suitable for production lines that continuously process endless material. By eliminating the need for a separate drive, synchronization problems between the punching unit and the strip feed are eliminated.

Benefit from lower operating costs without an external drive

A motorless rotary punch reduces your production running costs on several levels. The elimination of electrical drive components eliminates power consumption for the punching process, reduces wear parts, and simplifies spare parts management. Operators of roll forming systems benefit from a system that draws its drive energy directly from the production process.

Rotary punching without a motor for the production of thin profiles

The BRC series processes materials with a tensile strength of up to 350 N/mm² and thicknesses between 0.20 and 0.50 mm. These specifications make rotary punching without a motor the preferred choice for manufacturers of plastering angles, mounting strips, and similar construction profiles. The maximum material width is 80 mm, which is sufficient for most standard profiles in drywall construction and the assembly industry.

When punching, motorless rotary punches achieve a minimum hole spacing of 12 mm for single rows of holes. Narrower hole patterns can also be achieved by using a staggered punch arrangement. The web between adjacent holes is at least 4 mm. Hole elongation in the running direction is typically 1 to 3% of the hole diameter, with a maximum of 10%. For applications that do not require the highest precision, this tolerance offers an optimal balance between precision and cost-effectiveness.

Aluminum, plastic sheets, and continuous steel sheet can all be processed equally well with the motorless rotary punch. This variety of materials allows for flexible use in different production environments without the need for costly conversions.

Compact motorless rotary punch in the format of a profiling punch

The BRC punching insert requires only the space of a single profiling stitch in the production line. This compact design distinguishes the motorless rotary punch from larger motor-driven alternatives and greatly simplifies integration into existing systems. Roll forming systems can be retrofitted with punching functions without the need for extensive conversion work.

The space-saving design results from the absence of external drive components. Where motor-driven systems require additional installation space for motors, gearboxes, and control units, the motorless rotary punch manages with its basic mechanical structure. For production halls with limited space or already optimized lines, this compactness offers a decisive advantage in terms of capacity expansion.

Easy handling and quick integration into existing systems

Installing a motorless rotary punch in your roll forming system requires no complex electrical connection work. Since no motor needs to be controlled, there is no need for cabling, frequency converters, or programming synchronization parameters. The strip material itself drives the punching rollers as soon as the system is running. This direct mechanical coupling ensures that the feed speed and punching frequency automatically match.

In addition to the hardware, we also offer advice and support during project planning. Our service team will help you select the right tool configuration and assist with commissioning on site. Whether you are planning a new production line or want to expand an existing system, our motorless rotary punches can be flexibly adapted to your requirements.

Various tool options are available for your individual application. The punches can be configured according to the hole pattern and material type. We supply service parts and replacement tools from our own range, ensuring short delivery times and compatibility.
