Precision Turned Components

Our Precision Turned Components are the backbone of many industrial assemblies. We combine skilled craftsmanship with modern metrology to ensure every dimension matches your specifications. Whether it is a simple spacer or a complex valve stem, we apply the same level of quality control. We utilize a mix of CNC and Cam-operated automat technology to offer the best price-performance ratio based on your volume and tolerance needs. We support low volume high mix and high volume low mix production strategies.
