Machining operations are broken down into 3 standard processes: turning, drilling, and milling. Turning involves single-point tools that cut the rotating material, but it isn’t always the most beneficial process. Instead, multi-point tools used for milling, including burnishing tools, are becoming the superior option for metalworking.

If you are wondering if your machining process is the best it can be, this article will help explain what you should be using. Keep reading below to learn why you should choose multi-point tools instead of single-point tools.

What Is Turning?

Turning is the process of using a rotating workpiece to cut metal along a fixed blade. Single-point tools are used in this process since the blade is a fixed object. Turning is used to thin an object out to create parts with features such as grooves and threads.

What Is Milling?

Milling creates similar parts to turning, yet it is a very different process. Milling uses a rotating multi-point tool to create features onto a fixed piece of metal. Using multi-point tools allows for higher precision and durability at a higher production rate.

Multi-Point Tools Have Higher Precision

Precision is a factor to consider when deciding between single-point tools and multi-point tools. Multi-point tools are more precise because they make many small cuts that allow for smaller features to be created, unlike single-point tools that make larger cuts. Each blade of multi-point tools has smaller dimensions that can create the finer detailed cuts.

This process results in dimensional accuracy because there is less material removed by the blades. It is easier to control the amount of metal that is cut off. The high precision of multi-point tools allows for the cut edges to be as close to the target measurements as desired.

Single-Point Tools Are Less Durable

Single-point tools break or wear down easier than multi-point tools due to the presence of only one blade. The one blade takes on all of the heat that is caused by the metals interacting during the machining process. Multi-point tools have many blades to distribute the heat, which results in a longer life span.

Investing in Polycrystalline Diamond (PDC) tools can extend your tool’s lifespan even further. PCD tools combine complex aluminum components and short lead times to create a product that is dimensionally accurate. These tools are durable because they distribute heat well, are resistant to wear, and is the second hardest material to a diamond.

Multi-Point Tools Create a Higher Production Rate

Multi-point tools can be operated at higher feed rates than single-point tools because of the benefits listed above. Precision and durability cause higher feed rates, resulting in higher production rates. The precision and feed rate of multi-point tools minimizes wasted materials, which increases the amount of dimensionally accurate products created.

Since the blades in multi-point tools are more durable than single-point tools, they need to be replaced less. Their durability allows for the blades to be operated at higher speeds which creates product quicker. The quicker the product is made, the higher the production rate.

If you are looking into elevating your machining process and the equipment you are using, use these factors when deciding which tool to invest in. Single-point tools get the job done, but if you want higher production rates and precision with more durable tools, you should invest in multi-point tools instead.
