James Archdale & CO. Radial Arm Drilling Machine, 5.2 HP, 550V, 5 Spindle Speeds, 4 Feed Rates

The James Archdale & Co. Ltd. radial arm drilling machine is an industrial-grade machine tool designed for precision drilling and metalworking. This specific unit operates on a 550 V, three-phase electrical system at a frequency of 60 Hz, powered by a 5.2 HP motor. The machine features a centralized control system with a hand feed lever for manual operation. It provides five distinct spindle speeds: 57, 93, 131, 233, and 545 RPM. The feed rates are gear-driven and measured in inches per revolution (I.P.R.), offering settings at 0.0055, 0.014, 0.018, and 0.030 I.P.R. For maintenance and operation, the machine requires machine oil with a specific gravity of .979 and a Redwood viscosity of 990 seconds. Built with traditional engineering principles, these British-manufactured machines are known for their heavy-duty construction, featuring a robust column and movable arm that allows for flexible positioning over large workpieces. The design incorporates a heavy base with T-slots for secure fixturing and is CSA approved under number 10532.
