The former, "A Horizontal Milling Tooling for Cylinder Heads," integrates a multi-axis adjustment system that allows micro-rotations within ±5° and linear shifts up to 150mm, adapting to over 20 types of cylinder head models without retooling—slashing changeover time by 60%. The latter, "A Clamping and Positioning Tooling for Automobile Cylinder Heads," features a servo-driven rotating platform with 0.001° precision, enabling one-time clamping for oblique holes (30°-60°) and side groove machining. Field tests show it reduces position errors to ≤0.02mm, boosting per-unit processing efficiency by 45% while cutting scrap rates from 3.2% to 0.8%. These patents, born from 18 months of R&D and 500+ trials, solidify the company’s edge in aluminum alloy precision casting.
