Circle Boring & Machine Company was founded in 1960 and was built on our capabilities with precision boring and milling.  Our CNC milling, boring and turning capacity is today matched by few  in the industry.  The expertise we have in these areas of machining has helped our customers turn their innovations into realities.

We can machine parts over 20 feet long, weighing up to 40,000 pounds.  We also machine parts that fit in the palm of your hand.  Our 25,000 sq. ft. building has six bridge cranes in four separate bays.  We are more than just a typical job shop.

We have recently made major investments in our turning departments.  Our CNC vertical lathes can turn parts up to 68 inch diameter by 60 inches high. Be sure to check out our Large Part Turning page that details the types of turning work that we do.
