Horizontal and Vertical Milling

Atscott Manufacturing Inc., a full service machine shop, specializes in metalworking and high-quality machined components. We provide turnkey solutions to meet your machining requirements, from small-goods production in low and high volumes up to large-assemblies production.

We offer both horizontal and vertical milling as part of our services. The milling process uses rotating cutters to remove extra material from a piece of work. We’ll explain the differences between vertical and horizontal milling so you can choose the best option for your project.

What is horizontal milling?

The spindle of the CNC machine is oriented horizontally for horizontal milling. The spindle with the attached cutting tool will move side-to-side across the space available, removing any excess material. Horizontal milling machine cutters are usually disc-shaped, similar to a saw blade.

The spindle orientation allows the mill to create deep and heavy cuts on the workpiece. Horizontal milling is ideal for creating grooves, slots, and angled cut. Because they have larger beds and stronger motors, horizontal milling machines are the best choice for large or heavy components. Horizontal milling machines have many other benefits, including:

• Versatility. These mills are versatile and can be used with a variety of cutting tools at different speeds.
• Chip evacuation. When cutting narrow grooves or deep grooves into workpieces, chips can accumulate in the cut and between moving parts. Horizontal mills have been designed to remove chips easily, leading to a cleaner finish.
• Milling multiple sides. Horizontal machines can machine and cut multiple sides on a piece of work rather than just one.

What is vertical milling?

A spindle is also used to hold rotating cutting tools. The spindle of these machines is vertical and can move up and down in order to cut into the work-piece. Vertical milling machines come in two types: bed mills and turrets. Bed mills have a rotating bed that allows for full 3-axis movement.

Vertical milling has many benefits.

• Cost effectiveness. These machines are less expensive than heavy horizontal milling machines. This makes the process more affordable for both manufacturers and clients.
• Expertise available Vertical mills is the default choice for most manufacturers. It is easier to locate operators with the expertise needed to handle complex designs and unique projects.
• Less risk of error. The vertical orientation of the spindle makes it easier for operators to detect errors and mis-alignments. The result is a higher quality product, less waste of material, and a faster overall production.

Which one is right for your application?

The best choice for your project will depend on the specific requirements. Consider the following factors when selecting a process:

• The size and shape of a piece
• The number of planes that the piece must be worked on

Vertical milling is best suited for heavier workpieces, or for items that must be worked from multiple sides. Sinking dies and other projects are perfect for horizontal milling.
