In the mineral cutting processing stage of a major machine tool manufacturing company, mineral sludge adhered to mineral oil and floated in an 800L coolant tank. Over time, it absorbed moisture and settled, leading to the proliferation of bacteria and causing decay. Additionally, although the cutting oil was still usable, it was completely discarded within five months due to the presence of mineral oil and mineral sludge. As a result of a practical test using the oil-water separation device "LSSII-ECO Standard Unit," mineral oil and mineral sludge mixed in the cutting oil were separated and recovered. After its introduction, the cutting oil was not discarded for eight years, achieving a 16-fold extension of its lifespan, and long-life tests are still being conducted.

At the aircraft parts machining factory, we are processing parts by cutting them from aluminum blocks, and aluminum microparticles (μ) with little specific gravity difference from the cutting oil are floating up, adhering to the mineral oil as sludge. Additionally, this is likely to cause issues with the product accuracy of the machined parts and can lead to foul odors, which is why we dispose of the entire cutting oil four times a year. As a result of conducting a real machine test using the oil-water separation device "LSSII-ECO Standard Unit," we were able to separate and recover the sludge containing aluminum microparticles mixed in the cutting oil from the mineral oil. Since its introduction, we have achieved a long life of 24 times without disposing of the cutting oil for six years, and we are continuing to conduct long-life tests. 【Overview】 ■ Oil-water separation device used: LSSII-ECO Standard Unit ■ 30 minutes after the actual test: Separation and recovery of sludge containing floating aluminum microparticles (μ) and mineral oil. *For more details, please refer to the PDF document or feel free to contact us.

At an automotive parts processing company, a process for heat treatment of products involves performing gear hardening at a high temperature of 190°C using chemical agents. Using a filter press machine, black fine sludge particles under 100μ are collected from the chemical liquid, but the filter needs to be removed and cleaned every night, which incurs labor and costs. As a result of a practical test using the sludge recovery device "M1-250M," the collection and dewatering time was reduced to one-fourth of the conventional time, while filter cleaning time was reduced to one-fifth, and labor costs were halved, leading to significant cost savings.

In 2008, a major engine machining company used 6000L (6t) of cutting oil for machining processes and disposed of the entire amount of cutting oil three times a year. Approximately 2t of sludge generated during grinding processes was mixed into the 6000L of cutting oil, and the dewatering of the sludge during disposal was insufficient, making cost reduction difficult. After introducing four sludge recovery units "M1-250M," the long life of the cutting oil was achieved without replacement for two years. 【Overview】 ■ Test Date: December 28, 2008 - 3 days ■ Location: Major engine machining factory ■ Test Equipment: M1-250M (MAX 90L/min) x 4 units ■ Amount of Cutting Oil: Approximately 6000L (6t) ■ Cutting Oil Used: From a certain cutting oil manufacturer ■ Amount of Recovered Sludge: Approximately 2.5t *For more details, please refer to the PDF document or feel free to contact us.

At a major engine machining company, approximately 2 tons of metal sludge, including grinding wheels generated during grinding processes, mix with cutting oil, leading to the disposal of 6,000 liters of cutting oil three times a year. Additionally, due to insufficient dewatering of the sludge during disposal, disposal costs were higher than necessary. To solve this problem, a practical test was conducted using the sludge recovery device "M1-250M," resulting in a significant improvement in sludge recovery and ultimately enabling the long-life use of cutting oil. 【Overview】 ■ Test date: December 28, 2008, for 3 days ■ Location: Major engine machining factory ■ Test equipment: M1-250M (MAX 90L/min) x 4 units ■ Amount of cutting oil: Approximately 6,000L (6 tons) ■ Cutting oil used: From a certain cutting oil manufacturer ■ Amount of recovered sludge: Approximately 2.5 tons *For more details, please refer to the PDF document or feel free to contact us.

Many users utilize cyclone machines for the recovery of sludge generated during aluminum cutting. While these machines can handle large flow rates, most aluminum, fine powders, grinding (including grinding stones), cemented carbide polishing, and micro-particles with minimal specific gravity are largely mixed together, resulting in a limited amount of recoverable sludge. As a result, the clean tank at the bottom of the cyclone machine, which should collect the cleaned cutting oil, is often not sufficiently cleaned, and a significant amount of sludge remains. To address this issue, we used our sludge recovery device "M1-250M" to recover sludge from the clean tank at the bottom of the cyclone machine. [Overview (Partial)] - Implementation Location: Clean tank at the bottom of the cyclone machine (approximately 500L) - Sludge Classification: Aluminum - Recovery Device: M1-250M (Maximum processing flow rate 80L/min to 90L/min) - Recovery Time: 3 minutes x 5 times, totaling approximately 15 minutes *For more details, please refer to the PDF document or feel free to contact us.
