Firstly, parts for robotic applications often have a requirement to be strong, tough and lightweight. Materials such as aluminium have ideal characteristics and can easily be machined using CNC Machining.
Similarly POM (also known as Delrin and Acetal) is commonly used for robotic mechanical cnc machining parts. Easy to machine, it is known for its low friction, high stiffness and superior dimensional stability. As a low-cost plastic, it is also a very economical option.The following is about metal precision mechanical parts CNC machining.
