The VOLUMEC VASTC-SCAN is a QR code scanner module that integrates with the VASTC (Volumec Assisted Screwing-Tapping Control) touchscreen system on JOYTAP articulated arm tapping and screwing machines. Its function is straightforward: the operator scans a QR code affixed to the workpiece or work order, and the machine automatically loads all associated machining parameters — torque, speed, depth, pitch, and lubrication settings — without any manual data entry. This eliminates setup errors at job changeover and significantly reduces the transition time between different production batches.

How does QR-based job setup change the operator's workflow?

Without SCAN, an operator switching from one tapping job to another must manually recall or look up the correct parameters — pitch, depth, speed, torque — and enter them through the VASTC touchscreen. With SCAN, the operator simply presents the QR code to the scanner. The system retrieves the pre-saved recipe instantly, configures all parameters, and confirms readiness. The process takes seconds instead of minutes and removes the risk of entering an incorrect pitch or torque value that could damage threads, break taps, or produce out-of-spec assemblies. For high-mix production environments where changeovers are frequent, this single feature can recover significant productive time per shift.

What control modes does the underlying VASTC system provide?

The VASTC-SCAN leverages the full capability of the VASTC control platform. In tapping mode, it supports semi-automatic and manual operation with encoder-based constant-speed motor control, programmable chip discharge cycles, automatic lubrication timing, and thread count calculation. In screwing mode, the motor stops automatically when preset torque is reached, a green confirmation light signals completion, and a tightening counter tracks production output. Programs are password-protected, and on the VASTC 4.0 Wi-Fi variant, work reports — including date, time, thread count, torque, depth, and speed — can be downloaded remotely via smartphone, tablet, or PC.
