Inertia Friction Welding vs CNC Machining


Why should a printing or material handling OEM care about the difference between Inertia friction welding and CNC machining? You’re about to find out.

As the primary decision maker for your manufacturing company, you’re responsible for the survival of your business. You need to make smart decisions that keep your business competitive. When metrics show that you’re spending too much time or money in one area, it’s your responsibility to implement change.

Stop Spending So Much on Subassemblies

For example, metrics might tell you that you’re spending too much on your current subassembly provider. Of course you need those subassembly parts to sell your printing and material handling equipment to customers. But what if you found a provider who could build subassemblies faster, at lower cost? Now you have a decision that can fuel the growth of your company.

Are You Paying Too Much for Industrial Rollers?friction welding

Let’s take a look at a common subassembly for printing and material handling OEMs: industrial rollers. Traditionally, building rollers includes pre-machining the tubes, pre-machining the endcaps, assembling the endcaps to the tubes, and finish-machining the part. Finish-machining is important in order to achieve precise specifications. However, when you substitute inertia friction welding for part of the building process, you receive significant savings.

Inertia Friction Welding vs CNC Machining

Let’s take a closer look at how selecting a vendor who builds your rollers with inertia welding will save you time and cost compared to a vendor who only does CNC machining.


Inertia friction welding to near-net shape is 7x faster than CNC machining to final dimension. The huge difference is due to how inertia welding combines pieces that are already sized to end dimension, while the machining process needs time to cut material down to that end dimension.


Because inertia friction welding combines pieces already sized to end dimension, it uses 4x less raw materials than CNC machining from bar stock. Scrap chips equates to wasted money. Inertia welding also allows you to use expensive materials like steel in areas where strong material is required, and use less expensive materials like aluminum in areas where it isn’t required.

The way your subassembly providers produce product directly impacts your process. If they’re not utilizing industry best practices, or implementing innovative technology, it’s you who will pay for it. Don’t let that happen. Select a new provider.
