1. Materials and Hardness
(1)Base material: 40Cr alloy structural steel
(2)Heat treatment: Quenching and tempering, volume hardness HRC50-55
(3)Advantages: It features extremely high core strength and fatigue resistance, making it suitable for critical parts that bear high loads and wear
2. The precision machining capability is demonstrated
(1) External dimensions: Cylindrical part, specification Φ120 × 40
(2) Form and position tolerances: Fully controlled within 0.012mm, including but not limited to roundness, cylindricity,concentricity, etc., to ensure the dynamic balance and assembly accuracy of components under high-speed operation.
(3)Positioning precision hole tolerance: Key mating holes are strictly controlled within the tolerance range of 0 to +0.01mm. This design ensures a perfect clearance fit with the shaft parts, achieving precise positioning and slipping-free transmission.
3.surface treatment
(1)Process: Chemical nickel
(2)purpose:
uRust and corrosion prevention: It provides a uniform and dense protective layer for the substrate, effectively resisting environmental corrosion.
uSurface hardening: Further enhance surface hardness and wear resistance.
Aesthetics and consistency: Offers a matte or semi-bright silver-gray appearance, with uniform coating and no electroplating dead corners.
uAesthetics and consistency: Offers a matte or semi-bright silver-gray appearance, with uniform coating and no electroplating dead corners.
Feature
Processing this component is a comprehensive challenge, which requires successfully reconciling multiple opposing attributes on the same part:
(1)The balance between "hardness" and "precision" : To achieve a shape and position tolerance of 0.012mm at a high hardness of HRC50-55, a combination of CBN tools and precision grinding processes is required, and it relies on ultra-high rigidity machine tools to avoid vibration.
(2)The control of "strictness" and "stability" : The tolerance of the positioning hole is controlled within the unidirectional positive tolerance (0 to +0.01), which requires environmental control in the constant-temperature workshop, precise tool compensation strategies, and full-process quality monitoring.
(3)The balance between "substrate" and "surface layer" : The surface finish and cleanliness before chemical nickel treatment directly determine the quality of the coating. Through meticulous pretreatment processes, we ensure that the coating is perfectly combined with the high-hardness substrate, without peeling or defects.
Applications
(1) High-wear-resistant cams, rollers and bearing housings in precision automated equipment
(2) Precision positioning discs and fixture bases in semiconductor packaging and testing equipment
(3) Mold base guide sleeves and top rod fixing plates in the mold industry
(4) Core structural components in various heavy-duty and high-speed transmission systems
