Boring machines are crucial in any machine shop, allowing you to enlarge holes in a wide variety of materials. They come in three main types: table, planer, and floor.

They use an insert made of a grinding or cutting material, such as concrete carbide, to cut through the surface. Most modern boring mills are equipped with CNC technology, which allows machinists to pre-program the entire process and let the machine do the work for them.

CNC Boring Mills

A CNC boring mill is a heavy-duty machine used for boring (enlarging) holes in materials. This industrial machining tool is primarily used in industries like aerospace, automotive, and energy for components such as engine cylinders and turbine casings. It can also be used for reaming, which is the process of smoothing out the inner surface of a bore by physically shearing it.

Boring mills are typically operated using a CNC control system, which allows for precise control of the machining process. This user-friendly interface also simplifies operation for operators with varying levels of experience. Some models may even be compatible with automation systems for increased productivity and efficiency.

Horizontal Boring Mills

Horizontal boring machines are floor-type machining equipment that sits on the floor, unlike lathes or mills. These machines are used for bigger parts that would be too big to fit on a traditional machining center.

These machines are also able to handle a wider range of hole sizes than other machining tools. They do this by minimizing tool deflection. This means the boring bar doesn’t stick out as far as it normally would, which reduces the chances of missing tolerances.

Most boring machines have a spindle that extends out from the headstock to reach farther into the workpiece. This allows them to get to deeper features of the workpiece and makes it easier to remove the workpiece and cut the rest of the part. This feature also gives the boring bar more strength when applying cutting pressure, which can help ensure straight cuts and save time in machining. This is important to ensure the accuracy of your end product.

Jig Boring Mills

When a hole needs to be machined to an especially high level of accuracy, shops often turn to jig boring machines. They're a type of horizontal boring mills for sale that are designed with symmetrical components and operate in temperature-controlled environments to minimize thermal fluctuations that could affect accuracy.

Jig boring machines typically work with a wide variety of metals including aluminum bronze, brass, and phosphor bronze. These alloys are well-suited for jig boring because they're soft and typically easy to machine. They also have good corrosion resistance, making them ideal for machining applications like valves and plumbing systems. Another benefit of a jig borer is that it's much more accurate than a typical machining center, meaning it can achieve very precise tolerances without sacrificing the quality of the finished part. This is because a jig borer is capable of doing reaming, a process that's used to finish holes with very close dimensional tolerances and excellent surface finishes.
