UNIVERSAL SURFACING AND BORING MACHINE.
A modified type of surfacing and boring machine, made by George Richards and Co., Limited, Broadheath, near Manchester, is shown in the illustration above. It is built in three sizes to face and turn ranges 22in., 30in., and 35in. diameter. The No. 1. size is illustrated. The firm's latest improvements consist in gearing the facing head direct for facing and boring operations, and an additional pair of gear wheels is provided on the spindle frame for providing suitable speeds to the spindle for drilling and machining brass-work, thereby widening the scope of the machine. The top surface of the bed has also been increased in width, and is arranged with square instead of V-slides; while in order further to fit the machines for heavy cutting at high speeds, they have been strengthened up generally. All motions are automatic in both directions, and by means of a positive iced motion eight rates of feed are given in the longitudinal. transverse, and vertical directions, the feeds being instantly changeable or reversible.
Like all machine tools built by Messrs. Richards, these tools are made to guarantee limits of error.
