Multi-Spindle Screw Machining of Stainless Steel Knurled Pins for a Variety of Industrial Applications

Elge Precision Machining, Inc. is periodically asked to produce high volumes of stainless steel knurled pins. With almost 75 years of experience, Elge’s knowledge of turning and knurling enables us to increase cycle times while maintaining quality standards, which results in reduced costs and savings to the end user. Elge produces these stainless steel knurled pins — used in automotive, electronics, industrial, construction, and OEM applications — on 11 Davenport automatic screw machines. Made from 303 stainless steel, the pins have outside diameters ranging from 5/32″ to 3/4″ and lengths from 1/4″ to 12″. Working from customer specifications and 2D CAD drawings, multi-spindle screw machining is used to manufacture the pins to tight tolerances of ±0.001″. After being cleaned with solvent, the parts are dried for inspection. Following dimensional and visual inspection, the stainless steel knurled pins are tagged and dated to a specific screw machine and manufacture date. Documentation provided to customers includes certificates of conformance and material certifications. Delivery is typically accomplished in only two weeks following the start of production, with stocking programs available for larger orders.
