Process-safe assembly of screws while saving costs

CC-ErgoSpin

The Rexroth hand-held nutrunners of the CC-ErgoSpin product line enable a high degree of process reliability and long work times with minimal fatigue. Operation is carried out with the BS350 operating

Conduct function-critical tightening operations according to VDI/VDE 2862 with the new CC-ErgoSpin hand-held nutrunner

With the new Rexroth CC-ErgoSpin product line, users can now save money when conducting function-critical tightening operations according to VDI/VDE 2862: The ergonomic hand-held nutrunner optimizes the process and reduces scrap. Compared to pneumatic nutrunners the efficieny and reliability of the Rexroth tool ensures better process control and, thus, a higher degree of process reliability.

Component, screw, torque and angle of turn have to be perfectly matched to meet the requirements of quality and cycle time. Function-critical tightening operations, which are now found in countless branches of industry, are the specialty of the new Rexroth CC-ErgoSpin hand-held nutrunners. Especially designed for B-tightening operations according to VDI/VDE 2862, the nutrunner determines the required torque via the current control. The user operates and programs the CC-ErgoSpin via the intuitive Rexroth BS350 operating software. It contains statistical tools for detailed analysis of the tightening case. This prevents faulty tightening operations, decreases scrap, minimizes warranty costs and ensures a high degree of process control. The operating software can be used universally with all Rexroth nutrunners for A and B tightening operations.

The CC ErgoSpin stores up to 99 tightening programs that can be assigned to a specific component via a bar code scanner, for example. The nutrunner can thus replace several pneumatic nutrunners. This allows for clarity and space and saves costs: Compared to compressed air technology, the CC ErgoSpin cuts the total cost of ownership in half and uses up to 95 percent less energy, thereby conserving resources. Four sizes with working ranges from 2.4 to 40 Nm and output speeds of up to 1,090 revolutions per minute are available.

The robust design of the nutrunner allows for a long service life and has been tested under full load to one million cycles without maintenance. That makes it a safe and reliable tool, even in difficult environments, like oily workplaces. At the same time, the nutrunner allows for low-fatigue plant work due to its ergonomic handle design and low-vibration operation. Unlike with pneumatic nutrunners, noise production is low and the risks due to pressurized air lines are eliminated.
