Guidance on the recovery methods for sludge generated in "super hard/grinding processing" (case study publication).

Recovery of sludge from coolant liquid in (super hard and grinding processing) / Success case

◆ Issues (Before Implementation) 　● Maintenance tasks such as tank cleaning are difficult with only paper filters. 　● Fine sludge in the coolant adversely affects processing quality. 　● Looking for a separator that can "recover" "hard" sludge, among other things. ◇ Implementation Effects 　〇 Sludge recovery rate improved by approximately 4 to 5 times compared to conventional "filtration devices." 　〇 Processing quality improved as fine "hard sludge" no longer causes scratches. 　〇 High dewatering performance with almost no moisture in the sludge, reducing the burden of recovery tasks, among other benefits.

The strongest magnetic drum in history / Surface magnetic force of 9000 gauss! The "UK" has been newly added to the Fine Mag series, which has the highest customer rating No. 1.

● Magnetic force of 9000 Gauss (drum surface) ● Recovery capacity is an impressive 1.7 times that of the K-type (our standard model)! (Grinding sludge 5-15um) ● Demonstrates powerful recovery for hard-to-magnetize sludge (e.g., from carbide tool grinding)! (Here’s what’s different!) 1. High effectiveness in recovering hard-to-magnetize sludge generated in "carbide tool processing," which has been difficult to recover with conventional methods, as well as "ultra-fine sludge" from honing, lapping, super finishing, and electrical discharge machining. 2. Contributes to resource recycling by recovering "rare metals" (such as tungsten) contained in carbide sludge. 3. No parts that require regular replacement, such as "secondary filtration devices" (paper, diatomaceous earth, line filters), significantly reducing running costs and replacement labor.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
