Additional Insights & Technical Advantages

Material and Manufacturing Excellence

HT300 vs. HT200 Cast Iron Choices: HT300 provides higher tensile strength and better wear resistance, suitable for heavy-duty machining. HT200 offers cost efficiency with good damping properties—ideal for general-purpose applications. Hengfeng’s precision casting process ensures uniform grain structure, minimizing porosity and internal defects.
Straight-Line and Flatness Accuracy: After rough machining, each angle plate with locator grid undergoes a double-surface milling process to achieve a surface finish of Ra ≤ 1.6 μm. Final lapping brings flatness within 0.02 mm across the entire face. This exacting process reduces scrap rates and ensures long-term reliability.
Stress Relief and Aging Treatment: Following cast and rough-machining, every plate is placed in a controlled-temperature furnace (550 °C for 2 hours), releasing residual stress. A natural air-cooling process prevents thermal shock, guaranteeing dimensional stability in fluctuating shop-floor environments.

Locator Grid Advantages

Modular Fixturing: The uniform Ø12 mm hole pattern (40 mm or 50 mm pitch) allows compatibility with standard M12 clamping kits—T-nuts, dowel pins, and angle brackets. This grid accelerates changeover time by up to 40 %, reducing downtime between jobs.
Repeatable Rigidity: Locator grid holes are pre-bored with a positional tolerance of ±0.01 mm, ensuring that once you lock in a fixture, you can remove and remount workpieces with micron-level repeatability. This is crucial for high-volume batch runs where setup consistency equates to minimal scrap.
Versatility Across Operations: Whether you’re milling, drilling, or grinding, the grid pattern holds your workpiece squarely at a perfect 90° relative to the machine table or index head—enabling 5-axis machining and vertical/horizontal transitions without secondary fixturing.
