[Use Case] Detection of Drill Breakage Precursors [Failure Precaution Detection / Equipment Maintenance]

[Use Case] Detection of Drill Breakage Precursors [Failure Precaution Detection / Equipment Maintenance]

Constantly monitoring graphs! Introducing a case study that reduced unexpected stoppages on the production line.

We would like to introduce a case where the AC current sensor from "ParaRecolectar" was used to detect signs before the drill breaks. In deep hole machining, drills were either replaced regularly or after they broke, leading to sudden equipment stoppages due to unexpected drill breakage. By applying this case, it becomes possible to detect different waveforms during normal operation and send a stop signal to the equipment, allowing it to be halted before the tool breaks. [Case Overview (Partial)] ■Challenges - Want to know the signs before the drill breaks in the machining equipment - Prevent sudden equipment stoppages ■Implementation Method - Measure the spindle motor current of the machining equipment with an AC current sensor *For more details, please download the PDF or feel free to contact us.

[Use Case] Visualization of Power Consumption per Unit with Retrofitted Sensors [Energy Saving / Unit Consumption]

[Use Case] Visualization of Power Consumption per Unit with Retrofitted Sensors [Energy Saving / Unit Consumption]

Reduction of entry errors! Introducing a case that visualizes electricity consumption in units of equipment.

We would like to introduce a case where the AC current sensor and pulse input of "ParaRecolectar" were used to visualize electrical power with an aftermarket sensor. In measuring electrical power, the task of recording calculated results by operators had become a significant daily burden. As a result of the implementation, automatic measurement by the sensor became possible, leading to a reduction in labor hours for operators and the ability to identify bottlenecks. 【Case Overview (Partial)】 ■Challenges - Want to visualize electrical power per unit - Labor hours for aggregation are high - There are no sensors in the desired aggregation locations ■Implementation Method - Automatic measurement with aftermarket sensors *For more details, please download the PDF or feel free to contact us.

[Use Case] Visualization of Electricity Consumption [Energy Saving / Carbon Neutral]

[Use Case] Visualization of Electricity Consumption [Energy Saving / Carbon Neutral]

Accurate data recording by sensors! Introducing examples of visualizing electricity usage for each facility.

We would like to introduce a case where we used the AC current sensor from "ParaRecolectar" to identify neck facilities and reduce electricity costs. In measuring electricity usage, there were challenges such as a lack of manpower to conduct investigations and the costs associated with introducing measuring devices. As a result of the implementation, we were able to see the trends in daily electricity usage and identify the time periods with high usage. [Case Summary (Partial)] ■Challenges - Want to reduce electricity usage - Unable to narrow down countermeasure processes ■Implementation Method - Automatic measurement with retrofitted sensors *For more details, please download the PDF or feel free to contact us.
