1. Product Overview

2. CNC Machining Service Parameters (Standard Industry Specification)

3. Core Application Scenarios

• Industrial Automation Equipment: Fixed locking of optical shafts, guide rods, and cylinder rods on truss manipulators, laser processing equipment, and 3C automated production lines, ensuring stable operation of moving parts and no offset.
• Jig & Fixture System: Used as positioning clamp block and workholding component for assembly jigs, detection jigs, and processing fixtures, specially for clamping and positioning small cylindrical workpieces.
• Precision Manufacturing Equipment: Auxiliary fixing and positioning of mechanical transmission parts in precision testing equipment and non-standard automated machinery.

• General Mechanical Engineering: Shaft body limit fixing and component positioning for small and medium mechanical equipment, replacing traditional single-function brackets to improve assembly accuracy.

4. Professional Material Analysis

• Priority Material: Stainless Steel 304/17-4PH (70% industrial matching rate) Features: Excellent corrosion resistance, no rust in long-term workshop environment, strong structural toughness, not easy to deform after repeated clamping. No surface oxidation treatment required, maintaining stable clamping accuracy for a long time. Most suitable for automated fixture and indoor equipment working conditions.
• High Wear-Resistant Material: Tool Steel SKD11/S45C (25% application scenario) Features: High hardness after heat treatment (HRC 58-62), super wear resistance and anti-fatigue performance. Suitable for high-frequency repeated clamping, heavy-load working scenarios, effectively extending component service life.

• Lightweight Alternative: Aluminum 6061 (5% special scenario) Features: Light weight and easy processing, only applicable to low-frequency clamping and light-load positioning scenarios. Not recommended for long-term high-precision locking occasions due to easy plastic deformation.

5. Tolerance & Precision Capability

• Dimension Tolerance: Core clamping hole and mounting hole tolerance controlled within ±0.005mm~±0.01mm; overall outline tolerance ±0.02mm, far higher than ordinary mechanical parts.
• Flatness & Verticality: Mounting base flatness ≤0.01mm, verticality of clamping surface and reference surface ≤0.01mm, ensuring no shaking and offset after installation.
• Repeat Positioning Accuracy: The split elastic clamping structure ensures consistent clamping force each time, with repeat positioning accuracy up to 0.005mm, suitable for batch precision processing and detection.

• Assembly Matching Accuracy: All threaded holes and mounting holes are processed by one-time clamping, no secondary positioning error, perfect matching with standard fasteners and equipment shafts.

6. Manufacturing Difficulties & Technical Advantages

• Elastic Slot Deformation Control (Core Difficulty): The narrow penetrating slot directly affects the clamping elasticity and force uniformity. Unreasonable milling parameters will cause slot torsion and surface deformation. We adopt low-speed fine milling and one-time forming process to ensure uniform slot width and no deformation, ensuring consistent clamping force.
• Coaxiality Precision Control: The transverse locking screw hole and longitudinal clamping hole require strict vertical coaxiality. Offset will lead to uneven clamping force and shaft jamming. Our professional fixture positioning process controls coaxiality error within 0.008mm.
• Flatness Guarantee of Mounting Base: The multi-hole flange base requires high flatness. Secondary cutting and finishing grinding processes are adopted to eliminate machining tool marks and stress deformation, ensuring fitting degree with equipment platform.

• Deburring & Chamfer Precision: All sharp edges are precisely chamfered without burrs, avoiding scratch assembly personnel and scratching matching parts, improving assembly smoothness and product durability.
