VMT 2025 04 30 Delrin vs. UHMW: Delrin offers superior stiffness, dimensional stability, and precision, making it ideal for high-tolerance plastic CNC machined parts. UHMW, on the other hand, excels in abrasion resistance and low friction, making it perfect for wear-heavy applications. Your choice depends on whether you prioritize machinability and rigidity (Delrin) or durability and impact resistance (UHMW).

VMT 2025 04 24 Side milling is a CNC machining technique used to cut the vertical or angled sides of a workpiece with the side of the milling cutter. It delivers precise edge finishes and is ideal for slots, grooves, and profiles. It’s essential for CNC machined parts that require detailed surface definition or complex geometries on their vertical planes.
