Precision Custom Stainless Steel CNC Milling Parts Details
Custom Precision L-Shape Mounting Base
This L-shape mounting base is a non-standard custom CNC-milled structural component widely used in automation & robotics, medical devices, food & beverage equipment, and semiconductor manufacturing – where 90° structural transition and repeatable positioning are critical. Machined from solid material, it integrates a bottom mounting flange (for secure mounting to machine frames or worktables), a vertical mounting face (90° component transition), and a precision locating boss (datum for sensors, micro-cylinders, or probes) in one rigid, vibration-resistant structure. This one-piece solid construction reduces assembly alignment work and maintains stable positioning accuracy even under high-cycle, high-vibration operating conditions.
We offer full customisation – dimensions, hole layouts, boss size, material, and surface finish – all tailored to your exact requirements. 1-piece MOQ supported, with rapid prototyping options for urgent projects, and free DFM feedback included with every quote. We also manufacture identical or similar custom brackets, mounting bases, and precision components to your drawings.
