Unist's Electronic Control Regulates Lubricant Delivery

Unist Inc.’s new Pulse R electronic control is backwards compatible with new and existing 24VDC Coolubricator, Saw Blade Lube and Serv-O-Spray Minimum Quantity Lubrication (MQL) systems. The Pulse R ties into the system control solenoid valve and takes the place of a pneumatic pulse generator timer or logic block.

According to Unist, Pulse R’s two-button interface makes adjustment easy, and an easy-to-read display helps operators maintain accuracy and consistency between jobs. The Pulse R control is equipped with fault monitoring and visual feedback of output and input status, which is designed to give the operator confidence that the MQL system is performing properly. Four operating modes enable the Pulse R to deliver either continuous output or intermittent output with one or multiple “shots” of fluid, and enable for actuation on either power-up or from an input trigger signal. Pulse R also includes a locking feature to prevent tampering.

Unist has been manufacturing MQL solutions for metal cutting since 1957. Unist’s MQL solutions apply a minute amount of a high-quality lubricant such as Unist’s Coolube directly into the cutting tool/workpiece interface, which reportedly results in decreased fluid usage, cleaner, safer shops and floors and improved cut quality and tool life. Other benefits include clean, dry chips for easy and more profitable recycling, the elimination of costly coolant treatment equipment and coolant disposal costs.

Pairing a Unist System with the vegetable-based Coolube lubricant is said to make for machining operations that are friendly to the environment and to workers’ skin.
