Core Technical Capabilities

Equipment Portfolio

Technical Talent Pool

Over 30% of senior engineers on the technical team have more than 20 years of industry experience, while over 60% of core technical backbones possess over 10 years of working experience. The core team delivers full-process capabilities, including DFM drawing analysis, process route design, fixture scheme development, CAM programming and quality inspection.

Quality Management System

The company has obtained ISO 9001:2025 quality management system certification and implemented a three-stage inspection mechanism: first-piece inspection, in-process patrol inspection and final finished-product inspection. Equipped with sophisticated testing equipment including German ZEISS CMMs, Japanese KEYENCE vision measuring machines and high-precision height gauges, KGL realizes full-dimensional inspection and complete data traceability.

Typical Technical Case: Machining of Core Semiconductor Components for ASML

Component Technical Specifications

Analysis of Technical Difficulties

1. Material work hardening: SUS304 exhibits severe work hardening during cutting, resulting in tool wear rates 3 to 5 times higher than ordinary carbon steel.
2. Thermal deformation control: With low thermal conductivity (15 W/m·K), cutting heat accumulates heavily, making the 0.3 mm thin-wall structure highly susceptible to thermal distortion.
3. Low-rigidity structure: The thin plate features an aspect ratio of 25:1 and tends to produce elastic cutter deflection under cutting force.
4. Composite multi-feature precision requirements: Overlapping strict tolerances for multi-step structures, micro-holes, flatness, position and coaxiality.

Customized Solutions

Process Flow: Rough machining → 24-hour natural aging → Semi-finishing → Thermal cycling stress relief → Finishing

Cutting Parameters

Fixture Solution: Composite clamping system combining 40–60 kPa vacuum adsorption, auxiliary supports and soft jaw clamping with torque controlled at 0.8–1.2 N·m. Tool Solution: AlTiN-coated carbide cutting tools with large-radius sharp cutting edges.
