The CNC boring machine has revolutionized many jobs in the machine shop through its ability to economically create parts with a series of precise, perfectly-positioned holes or cuts. Available in table, planer, or floor models, the boring mill often is used to increase the accuracy and tolerances of holes and cuts.

How CNC Boring Mills Work

The most popular type of CNC boring mill, the table type, can handle pieces as large as 66 ft. The table supports the items being bored, while three axes drive the part toward the work spindle and create the holes. The machine, controlled by computerized systems, may do the rough part of process or the more precise cuts.

Boring is used to create holes of different depths, usually by making a series of multiple cuts and retractions. During the process, the axes spin at a high RPM, which produces intense heat that is dissipated by pumping coolant through a channel that runs the length of the boring bar. Many machines operate on fixed cycles based on preprogrammed subroutines called G-codes to ensure that the results will be uniform.

Applications for CNC Boring

CNC boring machines are useful for creating precision gears for equipment. A gear blank is cut, ground, and machined with accuracy. Given the sizes that a horizontal machine can handle, the gears meet the needs of industries such as aerospace, oil and gas, and defense, which require large parts.

Cost Effectiveness of CNC Horizontal Boring

Due to increasing metal prices, CNC machining is considered a cost effective way to produce gears and other parts with intricate precision cuts. Often made by forging or casting in the past, the cost of these parts has increased by 200-400% over the last decade. Though the machining process removes costly metal, it produces a more accurate part that lasts longer. The cost savings realized by machining has made many companies rethink how they manufacture and finish their original and replacement parts.

Selecting A CNC Machining Vendor

While many machine shops offer CNC machining, the one to choose is the one that has the proper equipment to do the job. For large-scale production, you need a facility that can handle the part size on work table sufficient to support its weight. Given that you will be working with costly materials, you want a company that is ISO 9001 certified, experienced in working with large parts in your industry, and staffed with trained machinists whose skills are continuously advanced through continuing education and certifications.
