Boring Machines

A boring machine is used to produce accurate, smooth holes in metal workpieces by enlarging existing openings with a range of bore types, including cemented carbide, steel and diamond. The diameter can be precisely adjusted via the boring head, which is mounted on a rotating spindle.

Often referred to as boring mills, these machines are capable of cutting through exceptionally thick workpieces. The average horizontal boring machine handles material between one and ten metres thick, while heavy-duty models can bore to depths of 20 metres or more.

• Horizontal boring and milling machines
• Functional and precise universal machines
• CNC boring machines for optimal processing of large workpieces

While large-scale operations rely on CNC boring machines for high-volume industrial production, smaller horizontal or table boring machines are equally well suited to workshop and mid-scale applications.

A metal boring machine typically consists of a headstock mounted on a fixed or mobile column. The main spindle connects to propulsion and feed mechanisms housed within the spindle stock. Depending on the workpiece, a range of drilling, boring, and milling tools can be fitted to the headstock to achieve the required finish.

While early table-type boring machines were operated manually, modern CNC boring machines can automate the entire manufacturing process. CNC boring uses a computer program to precisely guide the spindle and feed mechanism. An automatic tool changer combined with an adjustable clamping table minimises manual intervention, making CNC boring machines significantly more efficient and consistent than their predecessors.

A boring machine is used by any manufacturer requiring consistent, precise holes cut into metal. Modern boring machines produce component parts across a wide range of industries – including automotive, aeronautical and heating – and are the preferred choice for drilling large rivet holes into particularly thick metal or cylindrical boiler units. Thanks to CNC technology, the latest models deliver exceptionally high levels of precision while processing large volumes of workpieces daily.

Large multinational manufacturers rely on boring machines for plant engineering and the production of cars, industrial vehicles and ships. Smaller companies within supply chains can also benefit from these powerful devices by sourcing used boring mills, which are often fully reconditioned and serviced – making them every bit as effective and reliable as new models. These machines can be fitted with various tools and automated devices, allowing multiple operations to be performed without moving workpieces between machines. This flexibility is particularly valuable for smaller businesses looking to keep costs low while remaining competitive.

The used CNC boring machine market offers businesses of all sizes an opportunity to access precision equipment at significantly reduced costs. With a wide selection of used boring machines available from some of the most respected manufacturers in the industry – including SCHARMANN, UNION, and COLLET & ENGELHARD – it is easier than ever to find reliable, high-performance equipment that meets your exact requirements. Whether you are looking for a horizontal boring mill or a CNC floor borer, the secondhand market delivers proven machinery with a track record of performance.
