MODERN EQUIPMENT REVIEW Modern Machine Shop 139 BALL GAGE BAL-tEc Division Micro Surface Engr., Inc. 1550 E. Slauson Ave. Los Angeles, CA 90011 323-582-7348 • www.precisionballs.com Save time with the self centering spherical surface of the ball gage. When measuring a large number of holes it can be 100 times faster. Put one or two flats on the ball and find any out-of-round holes. Measure how parallel the space is between two surfaces and or the size. You can get into inside diameters or inside spherical surfaces of rod end bearings. Bend the stem to reach inaccessible locations, in confined areas, down in a hole, inside a cavity or in a buried feature which cannot be seen. Mount the ball on a wire for flexibility to go around corners in pipe and tubing, for example. Easily measure the width of grooves or the surfaces of spherical and toroidal features. Accurately measure the pitch diameter of bearing races, threaded surfaces and of gears Ball Gage instead of a cylindrical plug gage. Gundrilling Machine Increases Drive Shaft Production Volume Kays Engineering's DeHoff 518 Cell is a gundrilling machine for high-volume production of scroll compressor drive shafts. These shafts require a different-diameter hole to be drilled in each end for lubrication of the scroll bearing. The machine is made up of nine gundrilling spindles used to drill the opposing holes. Three gundrilling spin- dles on a single machine base produce shorter holes with a larger diameter. Deeper holes with a smaller diameter are produced using six gundrilling spindles on two separate machine bases with three spindles each. More spindles are dedicated to the deeper hole because of its longer cycle time, which results in a balanced throughput for each gundrilling operation, according to the company. The machine features a 0.5" (12.7-mm) gundrilling capacity and an 18" (457-mm) slide travel. It has a cast iron drill head base with hardened and ground steel box ways. Its hand-scraped and fitted saddle, gibs and straps replace linear guideways and milled surfaces for improved vibration damping and accuracy. | Kays Engineering Inc. | 660-886-9929 kays-dehoff.com F a b t e c h B o o t h B 8 6 2 9 w w w . c o s e n s a w s . c o m 8 7 7 . 9 3 5 . 5 7 2 8 CUT IT ON A COSEN
