What Is Vertical Boring?

Vertical boring is a type of machining that creates an accurate hole in a piece of metal or an existing workpiece. Often referred to as mills, these machines rotate a piece attached to a horizontal table. The borer ascends and descends while technicians secure the item needing the bore to the machine.

Vertical Boring Machines

Often referred to as vertical boring mills, these machines have a rotating piece connected to a horizontal table. The borer moves vertically, and technicians attach the item to be bored to the machine. This allows for the highest levels of precision and accuracy. These machines usually specialise in large-scale industrial operations. They often work on enlarging existing holes to create a size that meets the manufacturer’s requirements.

Here at PT Engineers, we take pride in our professional and flexible approach when it comes to our vertical boring services. We’ll ensure we work closely with you in order to establish exactly what you are looking for from vertical boring, and how we can achieve it. Additionally, we will always keep you updated throughout the process and adjust our service to fit your project’s specific requirements every time.

Horizontal Vs Vertical Boring

Boring Head Rotation

Horizontal boring machines rotate the workpiece around an X-axis with the boring heading moving horizontally. However, vertical boring machines rotate the part around a Y-axis with the boring head moving linearly.

Faster Turnaround

When it comes to working with large workpieces, the setup time required for larger and heavier pieces is much quicker and more efficient with a vertical boring machine than a horizontal boring machine. Due to their heavy-duty nature, there is also no need to worry about the workpiece bending or causing damage to the machine.

Flexible Table Diameter

Vertical boring machines can have an adjustable table diameter to suit the size of the project being worked on. This is particularly ideal for those larger and heavier workpieces. Although arguably horizontal boring machines have more versatility, our facilities are fully equipped with the right accessories to add on to our boring machines in order to increase their productivity.
