Linde Process Service ECENTLY a power shovel manufacturer reported how Linde Process Service helped per- fect a series of complicated flame- cutting operations: “We started to use oxy-acety- lene shape-cutting several years ago—at first, only for dipper teeth. Later we used it on many other parts for which the strength of rolled or forged steel was desir- able. “On these parts oxy-acetylene cutting proved so profitable that © Pinion gears, connecting links, reach blocks, pall levers and dipper teeth are shape-cut from strong alloy steels in routine operations. These dipper teeth are being accurately formed from alloy steel stock. : ——— ...-plants and warehouses in all industrial PREST-O-LITE ACETYLENE ... the standard for well over a quarter of a century.

They supplied data on most eflicient oxygen pressures, nozzle sizes, and cutting speeds. “Now, we have replaced nine machines with two shape-cutting machines. We are cutting heavy steel to tolerances of 1/32-in. and less. We shape-cut parts accu- rately from steel 20 in. thick. An- gle corners and curved cuts are simple for us.” By translating proved methods into terms of actual plant require- ments Linde Process Service helped organize these shape-cut- ting operations for greatest speed, economy and dependability.
