Introduction: Coolant — the Hidden Cost Driver in Metalworking Coolant and cutting fluids are essential for precision machining, but they come with recurring costs. As these fluids degrade, manufacturers face increased tool wear, quality issues, disposal fees, and the expense of frequent fluid top-offs. Implementing coolant recycling can significantly mitigate these costs. Fortunately, modern integrated separation and filtration systems can […]

PRAB’s end-to-end systems—combining chip reduction, fluid separation, and coolant recycling—let manufacturers reclaim up to 75% of their cutting fluids and reduce waste disposal by up to 90%. Closed-loop chip and coolant recovery is no longer a “nice-to-have”—it’s now a profit-center and risk-reduction strategy. PRAB® has spent more than 70 years engineering and supporting USA-built systems that help manufacturers optimize their […]

Paper Bed Filters remove fine metal particles and debris down to 5 microns—extending tool life, improving machining accuracy, reducing downtime, and lowering disposal costs. Why Contaminated Fluids Cost Metalworking Facilities Money Q: What problems do dirty coolants and cutting fluids cause? Accelerated wear on pumps, valves, and spindles from chips and fines. Degraded fluid quality from tramp oils and bacteria, […]

The One Big Beautiful Bill Act (OBBBA) has reshaped how U.S. manufacturers can expense equipment, buildings, and research and development (R&D) costs. At PRAB, we’re serious about helping manufacturers become more successful in 2026 and beyond — with rugged, reliable equipment and by helping you optimize the purchase and commissioning process to capture every available tax advantage. Below is a […]

Water compliance isn’t merely about avoiding fines—it’s a prime opportunity to optimize operations, reduce costs, and generate revenue. Industries across manufacturing, utilities, and pharma face increasingly strict wastewater regulations. However, by embracing strategic systems and innovative technologies, many organizations are turning wastewater compliance into a profit center. Know Your Wastewater Composition—The First Step to ROI Understanding the chemical and physical […]

In manufacturing, most equipment is expected to last a few years—maybe a decade if it’s tough. But every once in a while, a machine goes above and beyond, becoming part of a company’s story. At Zircoa, a U.S.-based producer of high-performance ceramics and metal oxides, that story belonged to a PRAB Roller Bucket Conveyor. Installed back in the late 1970s, […]

Ultrafiltration (UF) technology enables manufacturers to recycle water from tumbling and deburring processes, reducing water and sewer costs by up to 99%, decreasing chemical usage, and maintaining compliance with stringent environmental regulations—all while enhancing operational efficiency. The Manufacturing Challenge A U.S.-based die casting and fabrication manufacturer faced a significant challenge: managing wastewater from two vibratory deburring systems without exceeding local […]

The recently passed One Big Beautiful Bill Act (OBBBA) is more than political news—it represents a significant shift in the U.S. industrial landscape. With billions of dollars being directed toward infrastructure, advanced manufacturing, clean energy, supply chain modernization, and workforce development, this legislation creates unique opportunities for manufacturers to strengthen operations, increase competitiveness, and invest in long-term growth. For business […]

In heavy manufacturing, the life expectancy of most equipment is often measured in years, not decades. Yet, some industrial conveyors prove that with the right design, materials, and maintenance, systems can reliably operate for nearly half a century. One such example is a PRAB Conveyor, installed in the late 1970s at a U.S.-based manufacturer of refractory materials. After 48 years […]

Question: What is “Circularity” in metalworking? Answer: Circularity in metalworking refers to the practice of designing and manufacturing products that recover, reuse, and recycle materials in a closed-loop system, thus reducing waste and environmental impact.   From Linear to Circular: The New Industry Mandate The traditional “take‑make‑waste” model is under increasing pressure. A circular economy—or “Circularity”—refers to designing systems that […]
