Precision Machining for Instrument & Laboratory Equipment

We manufacture high-precision components for precision instruments, laboratory equipment, and diagnostic systems — including functional components, connectors, fixtures, and precision housings. With ±0.01mm tolerances, diverse material capabilities, and full MES traceability, we support your instrument projects from prototype to production.

Precision Instrument Component Manufacturing Capabilities

We deliver high-quality custom-machined components for precision instruments, laboratory equipment, and diagnostic systems — functional components, connectors, fixtures, guides, and precision housings. Every project follows our full quality-control workflow, from raw material incoming inspection through final dimensional verification. We machine a wide range of materials including stainless steels, tool steels, copper alloys, and engineering plastics — detailed material capabilities are listed below. With 3 CNC machining centers, wire EDM, surface grinders, and precision inspection equipment including Nikon projectors and TESA height gauges, we ensure consistent quality across every batch. No minimum order quantity — we treat every part with the same rigorous quality standards.

Case Study: Precision Functional Component for Laboratory Instruments

Background

A laboratory instrument manufacturer required a high-precision functional component for a new diagnostic system — used in sample processing and measurement applications.

Challenge

  • Material: 1.4528 stainless steel

  • Hardness: HRC54-56 (after heat treatment)

  • Dimensions: Φ39.5 × 52.3mm

  • Surface finish: Ra 0.4μm

  • Tolerance: ±0.005mm on critical surfaces

Our Solution

  • CNC precision machining with grinding allowance

  • Heat treatment to HRC54-56 followed by precision grinding

  • Surface finishing to Ra 0.4μm

  • 100% inspection on critical dimensions via Nikon profile projector and TESA height gauge

Result

  • All parts met dimensional specifications (±0.005mm achieved)

  • Surface finish achieved per requirement

  • Parts passed 100% inspection

  • Customer placed repeat orders
