Common Manufacturing Processes for Motorcycle Parts

There are several machining processes manufacturers apply in the fabrication of motorcycle parts. To a large extent, CNC milling and turning remain the commonest. Even so, other machining techniques like grinding, drilling, and laser cutting exist. Learn more about the standard machining processes below:

CNC milling process1. CNC Milling

CNC milling involves an automated machining process that controls the speed of rotary cutting tools and feed rate. These cutting tools rotate and move across the surface of the workpiece. More so, during milling, the excess materials get removed until the needed shape and size of the motorcycle parts gets formed.

CNC milling is most compatible with aluminum, copper, and plastic materials. Besides, it is well-suited for fabricating asymmetrical motorcycle parts. This is because the excellent machinability of these materials allows experts to manufacture parts with curves while getting the necessary precision. Hence, you’ll find that experts often apply CNC milling in customizing motorcycle wheels.

CNC turning process2. CNC Turning

Similarly, CNC turning operations involve reducing the diameter of the workpiece. This machining process continues until the desired dimension of the motorcycle part gets shaped. But then, note that this machining method requires affixing the bars of the workpiece in a position. Then, the multi-bladed cutting tool removes the excess materials.

Turning is compatible with various materials. This includes aluminum, stainless steel, copper, plastics, zinc, magnesium, and titanium. Experts often apply CNC turning in the rapid manufacturing of high-precision motorcycle parts. More specifically, it applies to engine components. This includes pistons, cylinder heads, and camshafts.

Surface Finishes and Post-processing Options for Motorcycle Parts

Surface finishes are processes conducted after machining. To a large extent, these post-processes help improve the specific properties of the machined motorcycle parts.

Below are some of the standard surface finishes applicable to motorcycle parts:

This electrochemical process involves coating the surface of machined motorcycle parts with aluminum oxide. Thus, this helps improve the durability, aesthetics, and corrosion resistance of machined motorcycle parts. Even so, the suitable components for this surface finish are those that conduct electricity. Besides, most finished pieces get brittle after this finishing technique. So, anodizing is ideal for aluminum motorcycle parts.

2. Polishing

Generally, this surface finishing involves smoothening machined motorcycle parts using an abrasive material. It also entails creating a glittery surface through the addition of chemicals. Thus, polishing helps remove scratches and nicks while enhancing the shine and luster of the finished parts. But this surface finish method is not well-suited for CNC motorcycle parts that must maintain high precision.

3. Bead Blasting

Bead blasting involves shooting high-pressure glass or steel bed at the surface of machined motorcycle parts. Thus, this process aids in sealing up pores and cracks, creating uniform wear and tear-resistant surface. Bead blasting also improves the aesthetic quality of the CNC motorcycle parts. Yet, this post-process technique is unsuitable for small and high-precision motorcycle components.
