Boring mills, also called metal cutting boring machines, increase the size of holes in a component and provide high tolerance and accurate cuts. These machines are the most suitable cutting machines for heavy components.

Boring mills improve the manufacturing productivity and accuracy in a wide variety of heavy industries like aerospace, construction, industrial, mining, energy and oil.

You can buy different types and sizes of metal cutting boring mills depending upon your application needs. There are horizontal boring machines and vertical boring machines. Furthermore, you can select a manually operated mill or a CNC boring mill.

Some important parameters you must consider before you select a boring mill are:

1. Type of boring mills: horizontal or vertical boring mills
2. The shape, size and quantity of the components to be bored or machined
3. The surface finish required

The best contacts and resources to help you get it done

Buy a boring mill from a reliable metal cutting boring mills manufacturer

Once you understand your requirements, go to a specific manufacturer to buy a suitable boring mill.

I recommend: MAG Giddings & Lewis provides horizontal boring mill machines for heavy-duty cutting in a variety of models such as plain table boring mill, rotary table boring mill, boring mill with pallet shuttle and tool changer and floor type boring mill. Moore Tool Co. is another source from where you can buy a 3-axis rotary jig borer and a 5-axis jig borer boring machine. B&D Manufacturing is a reputable manufacturer of portable align boring machines that you can use for on site repairs. Cincinnati Gilbert Machine Tool is another manufacturer of horizontal boring mill machinery.

Buy a boring mill from boring mill distributors

You can also buy the boring mill machine from a boring mill distributor after comparing boring mills available with different suppliers of boring mill machinery.

I recommend: Addy Machinery is a supplier of boring mill machinery manufactured by Nomura. Another resource to buy boring mills and lathes is Harris Machine Tools, a distributor of many types of boring mills offered by different manufacturers. Further, Gross Machinery Group is a distributor of a wide range of horizontal and vertical boring mills.

Buy used and reconditioned boring mills from suppliers of used boring mill machinery

Try buying used boring mills for a cost-effective solution for your milling applications.

I recommend: Manta Machinery & Equipment is a supplier of used horizontal, vertical, CNC and manual boring machines. ABL Technology is another supplier of both used CNC horizontal boring mills and used CNC vertical boring mills. JBM Technologies is one more metal cutting boring machine supplier that sells used boring mills with a service guarantee and trains the operator.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Avoid large length to bore diameters, as it may deflect the cutting tool in the boring mill.
• •  The boring arm that holds the cutting tool must be very rigid to withstand the hard materials and pressure involved in cutting or boring.
