ABSTRACT:
A portable milling machine is provided for solving in-place machining problems encountered on turbines, pumps, electric motor bases, and other types of field equipment requiring a close tolerance, machined surface prior to installation. Such portable milling machine is set up at a job-site using a plurality of levels in conjunction with an optical leveling kit and a vertical scale magnetically mounted at selective locations on such portable milling machine during set-up. The set-up time for such portable milling machine substantially is cut in half by using levels in conjunction with optics and accuracy may be achieved within 0.001 to 0.002 of an inch.
