Product Details:

REXROTH 608600004 is a dedicated tightening controller unit from Bosch Rexroth nutrunner assembly system, designed to match Rexroth servo tightening spindles for closed-loop torque and angle monitoring. It supports multiple preset tightening programs and real-time data traceability, built for mass production fastening stations that require high tightening consistency and quality record storage. This legacy controller is mainly circulated as spare replacement for old automotive assembly lines.

This tightening controller receives encoder and torque feedback signals from the matched nutrunner spindle, and executes configurable tightening sequences including torque-control, angle-monitor, yield point detection and soft joint strategies. It communicates with upper PLC via fieldbus interface to upload tightening results, alarm codes and batch data for production traceability. Separate power terminal and signal terminal layout reduce electromagnetic interference in industrial cabinets with inverters and switching modules.

This unit is a standalone control cabinet module without integrated driving spindle. It supports tool recognition and parameter group switching for multi-model mixed production. Built-in over-torque, over-angle, stall and signal loss alarm functions protect the spindle and workpieces during abnormal fastening. The internal circuit board adopts reinforced anti-virus coating, suitable for workshop environments with vibration and fine dust.

It supports parameter editing, curve viewing and batch data export through Rexroth tightening configuration software. Users can set tolerance windows, retightening rules and signal output logic according to assembly process requirements. Every finished controller passes factory validation before shipment, including communication test, program switching test, feedback signal matching test and long-time stability test to guarantee stable performance in multi-shift automated fastening production lines.

It is widely deployed on automotive powertrain assembly stations, new energy battery component fastening lines, household appliance assembly machinery and metal fitting bolt tightening automation cells. Typical application scenarios include multi-spindle tightening stations, mixed-model assembly lines, quality-critical bolt joining processes and production data acquisition platforms. Automation integrators select this Rexroth tightening controller for its flexible multi-program management, reliable feedback processing and seamless compatibility with Rexroth servo nutrunner spindles.
