Swiss machining vs CNC turning for custom parts..webp

Swiss Machining vs CNC Turning: Which Is Right for Your Part?

Swiss machining and conventional CNC turning can both produce precise turned parts, but they support and move the workpiece differently. For a slender pin, a short bushing, or a shaft with cross-holes, those differences can affect deflection, setup requirements, cycle time, and finished-part cost. This guide explains what to compare, when each route deserves consideration, and which drawing details help a manufacturer recommend a suitable process.

Repeat order for matte T300 carbon fiber car emblems with two-sided clear coating.jpg

Repeat Order for Matte T300 3K Twill Carbon Fiber Car Emblems

Following the successful completion of the first custom carbon fiber car emblem project, the US customer placed a repeat order with updated material and finishing requirements. The new order included several custom emblem profiles manufactured from T300 3K twill carbon fiber with a matte appearance. Unlike the original order, which required painted chamfered edges and an unpainted bonding surface, the repeat order specified clear coating on both sides. The different emblem geometries included sharp outer tips, narrow connecting sections, curved profiles and multiple internal cutouts, requiring careful CNC machining, edge preparation and coating control.

Custom T300 Carbon Fiber Car Emblem for a US Customer

This case study presents a custom carbon fiber car emblem manufactured for a customer in the United States. The emblem was made from glossy T300 3K twill carbon fiber and precision-cut using a CNC engraving and cutting machine. Its complex profile included sharp corners, narrow sections and chamfered edges that required careful machining. According to the customer’s requirements, the chamfered surfaces were painted, while the bonding side was left unpainted and prepared for adhesive installation on the vehicle.
