This listing features a Dynamic YMR-840 radial drilling machine manufactured in 1970 by Yodogawa Machinery MFG Co., Ltd, Japan. The machine is designed for turning, milling, and drilling operations. It is equipped with power elevation to the arm and power down feed, facilitating precise vertical adjustments during machining. The worktable measures 36 inches by 15 inches and is a tilting box table, allowing for versatile positioning of workpieces.
The radial drill includes a 3/4-inch capacity Jacob’s chuck, suitable for holding various drill bits securely. The column diameter is 8 inches, and the arm has a reach of 32 inches, providing ample workspace for drilling larger components. The spindle features a 4MT taper and offers a range of speeds from 50 to 1500 RPM across nine settings, accommodating different drilling requirements. Spindle feeds are adjustable with increments of 0.003, 0.0063, and 0.0102, enabling fine control over the feed rate.
The motor powering the machine delivers 2.2 kW with a 220/4450V, 3-phase electrical supply. The machine’s overall dimensions are approximately 5 feet in length, 30 inches in width, and 7 feet in height, with a weight of around 3,500 pounds.
Additional visible components include a handwheel for vertical feed control located on the front, an electrical control box mounted on the arm with start and stop buttons, and a flexible coolant hose positioned near the spindle to assist in cooling during operation. The machine shows signs of use, including surface rust and wear on the base and worktable, as well as paint chipping on the body. The worktable surface exhibits multiple drilled holes and discoloration consistent with heavy use. The base is mounted on a wooden pallet for support and transport. An analog ammeter gauge is also visible on the left side panel, providing electrical monitoring.
This radial drilling machine is a robust industrial tool suitable for various machining tasks, reflecting its extensive operational history and solid construction.
