CNC 850 Heavy-Duty Single-Head RAM Sinker Machine for Large Mold EDM. Heavy-Duty Capacity for Large Molds: The CNC 850 features a 1050 x 600 mm worktable and supports workpieces weighing up to 3000 kg, making it suitable for medium and large mold cavity machining. Large X/Y/Z Machining Travel: With 800 x 500 x 400 mm X/Y/Z travel, the machine provides sufficient machining space for large cavities, deep ribs, wide mold inserts and complex conductive components. High Electrode Load Capacity: The electrode head supports electrodes weighing up to 200 kg, allowing the machine to handle larger electrodes for deep and complex mold cavities. Intelligent CNC Machining Control: The CNC control system supports machining-file storage, automatic processing and intelligent discharge-condition adjustment for more convenient and consistent mold p. 10-Stage Automatic Finishing: The 10-stage automatic finishing function supports progressive machining from roughing to finishing, reducing repeated manual parameter adjustment. Mirror-Finishing Circuit: The integrated mirror-finishing circuit supports improved cavity surface quality under suitable electrode, material and discharge conditions. Anti-Carbon Deposition Detection: Anti-carbon deposition detection helps identify unstable discharge conditions and supports reliable machining of deep cavities and narrow mold features. Automatic Electrode Wear Compensation: Automatic electrode wear compensation helps maintain consistent machining depth during repeated cavity, multi-position and multi-hole processing. Large Dielectric and Filtration Capacity: The machine is equipped with a 1600 x 1100 x 600 mm working oil tank and a 980 L filtration tank to support long-duration EDM machining and debris removal.
