        "question": "What is the best vacuum for CNC coolant, metal chips, and sludge?",
        "answer": "The best system depends on what makes up most of the load. A dry chip vacuum is designed for dry chips, swarf and shavings. A sump or oil-and-swarf vacuum is better when coolant, chips and sludge are collected together and the liquid must be separated or returned. A general wet-and-dry vacuum may handle spills and mixed maintenance debris but may not provide the chip basket, liquid filtration or pump-back workflow needed for sump service. Size the unit around the largest sump, solids load, desired cleanout time, discharge distance, power supply and maintenance schedule.",

      {
        "faq_id": "V10-FAQ-009",
        "question": "Can a sump vacuum separate coolant from metal chips?",
        "answer": "Yes, when the selected configuration includes the right solids basket, sieve or separation stage. Larger chips and swarf are retained in the solids section while coolant passes into the liquid tank. A washable liquid filter can reduce smaller suspended solids, and some units can pump filtered coolant back to the machine, drum or tote. Separation performance depends on chip size, fines, sludge, filter rating and flow. A sump vacuum is not automatically a coolant-polishing system, so applications requiring very fine filtration, tramp-oil removal or biological control may need additional coolant-management equipment.",

      },
      {
        "faq_id": "V10-FAQ-010",
        "question": "How often should CNC coolant sumps be cleaned?",
        "answer": "Use condition-based and preventive-maintenance triggers rather than one universal interval. Cleaning frequency changes with machine utilization, work material, chip load, filtration, coolant type, tramp oil, fines, bacterial growth and production tolerance. Common warning signs include odor, visible sludge, restricted flow, unstable concentration, poor surface finish, shortened tool life or repeated coolant problems. Record sump condition and cleanout time during maintenance so the interval can be adjusted by machine or process. High-load operations may require frequent partial removal plus scheduled full cleanouts.",

      {
        "faq_id": "V10-FAQ-011",
        "question": "What is the difference between metal chips, swarf, shavings, spirals, and sludge?",
        "answer": "Chips and shavings are general terms for material removed during machining. Swarf often refers to the mixed metal fragments produced by cutting or grinding. Long spirals and bird-nest chips can bridge openings or tangle in small hoses, while short chips move more easily. Sludge is the dense mixture of very fine metal particles, coolant, tramp oil and settled contaminants at the bottom of a sump. Shape, size, density and wetness affect hose diameter, pickup tools, vacuum performance, separator design, filter loading and the safest way to empty the collected material.",

      {
        "faq_id": "V10-FAQ-012",
        "question": "Should a shop use a chip vacuum or a coolant sump vacuum?",
        "answer": "Use a chip vacuum when the material is mainly dry chips, shavings or swarf and the priority is moving solids into a bin or separator. Use a coolant sump vacuum when liquid and solids are mixed, the machine sump must be emptied, chips need to be separated and the coolant may be returned or transferred. A wet-and-dry vacuum fits broader maintenance cleanup but may not include the separation and discharge functions of a dedicated sump system. The decision should consider liquid percentage, chip geometry, sludge, tank volume, filter target and discharge workflow.",

      {
        "faq_id": "V10-FAQ-013",
        "question": "Can recovered coolant be reused after vacuuming?",
        "answer": "Recovered coolant can often be returned when the selected system separates chips and filters the liquid to a level acceptable for the process. Reuse still depends on coolant concentration, tramp oil, fines, bacteria, cross-contamination, material compatibility and the machine’s filtration requirements. Check the recovered fluid before returning it, especially when cleaning different alloys or machines. A sump vacuum removes and separates bulk contamination; it does not automatically correct concentration, remove all fine particles or restore degraded coolant. Additional filtration or coolant treatment may be required.",

      },
      {
        "faq_id": "V10-FAQ-014",
        "question": "What size sump vacuum is right for a CNC shop?",
        "answer": "Begin with the largest sump or tank that must be serviced, then consider how much liquid and solids are normally removed, the target cleanout time and whether multiple machines are cleaned during one maintenance window. Also account for chip-basket capacity, sludge load, pump-back or gravity discharge, hose length, vertical lift, access around the machine, available voltage or compressed air and the distance to the return container. A smaller unit can suit frequent machine-side service; larger tanks or centralized maintenance programs usually justify higher capacity and continuous-duty equipment.",
