Product Description:
This fixture base plate is made of 45# steel through integral forging and precision grinding, specially designed for high-precision machining scenarios with significant core advantages. Firstly, it has excellent positioning accuracy: surface flatness ≤0.01mm/m, adjacent positioning hole spacing error ≤0.005mm, ensuring workpiece clamping repeat positioning accuracy up to ±0.003mm, 60% higher than ordinary cast iron base plates. Secondly, it has outstanding wear resistance: surface treated with quenching (hardness 55-58HRC) + nitriding, reducing friction coefficient to 0.15, extending service life to over 8 years. Thirdly, it has strong structural stability: adopting T-type reinforcing rib design, deflection ≤0.02mm/m, capable of withstanding clamping force over 500kg without deformation. In addition, the base plate reserves multiple sets of standardized positioning holes (φ6-φ20mm) and T-slots, compatible with various clamping components, which can quickly adapt to different workpieces without secondary processing.

Applications:
This fixture base plate is widely used in precision manufacturing: In auto parts processing, it provides stable positioning for complex workpieces such as engine blocks and gearbox housings, ensuring milling/drilling accuracy. In aerospace parts production, it adapts to titanium alloy and aluminum alloy thin-walled parts processing to avoid clamping deformation. In the mold manufacturing industry, it is used for grinding positioning of templates and cavities, ensuring mold clamping accuracy ≤0.01mm. In electronic equipment processing, it provides multi-station simultaneous clamping for small parts such as mobile phone middle frames and computer casings, improving production efficiency by 30%. In addition, it can also be used for batch processing of medical device parts and precision instrument components, reducing product defect rate through high-precision positioning.
Customization:
Comprehensive customization services are provided to meet special processing needs: Size can be customized according to workpiece specifications (minimum 100×100mm, maximum 2000×1500mm), with flatness maintained at ≤0.01mm/m. Materials can be 40Cr (improving impact resistance by 20%) or stainless steel (suitable for humid environments). Surface treatment supports chrome plating (enhancing rust resistance) or blackening (reducing reflection). Structurally, it can be customized with special-shaped positioning holes, inclined guide grooves, weight reduction holes, or integrated with reference blocks, support columns and other components. The sample proofing cycle is 5-7 days, with a monthly production capacity of 5000 pieces, and three quality inspections (blank/semi-finished/product) throughout to ensure accuracy.
