High-Pressure Coolant System Automatically Adjusts Volume
MP Systems’ VR8 variable-volume, high-pressure coolant system is part of the company’s VR series.
MP Systems’ VR8 variable-volume, high-pressure coolant system is part of the company’s VR series. The system is said to be durable and energy-efficient, only using as much horsepower as needed to set pressure and automatically adjusting the volume to maintain it.
Variable volume flow adjusts to much as 8 gpm. Pressure is adjusted from the system’s programmable logic controller and controlled by the cutting machine’s M code.
Programmable pressures range from 250 to 1,000 psi, and systems have 50- or 70-gal. vertical reservoirs for use with water or oil-based coolants. All come with two quick-change large capacity filter bags, a machine installation kit and a two-year parts warranty.
Precision Tool Technologies found capacity for diversification not by adding machines, people or space, but by freeing up time. Running unattended—running so it can machine through all 168 hours in the week—has enabled this shop to use hours when staff is present to deliver work that lands outside its established specialty. To achieve unattended machining, some of the biggest challenges have related to basic details such as chips and coolant.
Minimum quantity lubricant can save money, improve tool life and improve the part finish. But it may involve changes to both the equipment and the processing strategy.
This shop provides a case in point of the substantial savings that can be realized with the proper coolant formulation. Rustlick Ultracut Pro, available from ITW Rocol North America, lasted twice as long in the sump than the shop’s previous coolant, leading to significant operating and maintenance cost savings.
