Car Rearview Mirror Housing Parting Line Removal
Product Preprocessing: Injection Molding
Product Postprocessing: Baking Paint
Product Requirements: Evenly remove parting lines, no burrs, no sand marks
Processing Method: Workpieces are positioned using snap fasteners, 4 stations are processed simultaneously, using eccentric wheel + sponge sanding and polishing
Core Advantages:
1. Complex Surface Processing Capabilities:
Car rearview mirrors (especially housings, bases, and complex styles with turn signals) usually have complex double curves, freeform surfaces, and various changes at edges and corners.
Approach the workpiece surface at any angle: Always perpendicular to the local normal direction of the polished point, ensuring the most effective material removal rate and the best surface finish.
Flexible Avoidance: Easily handle deep cavities, concave surfaces, steep edges, etc., avoiding collisions between the tool and the workpiece or fixture.
Maintain optimal working distance and posture: Maintain the optimal distance and contact angle between the polishing tool and the workpiece surface when moving on complex contours.
2. High Precision and Consistency:
The CNC five-axis system can precisely control the tool path, feed rate, rotation speed, and pressure (if force control is equipped).
Complex polishing paths can be programmed and precisely repeated to ensure high consistency in the polishing effect of each rearview mirror part, meeting the strict appearance quality requirements of the automotive industry.
Eliminate individual differences and instability caused by manual polishing.
3. Improve Efficiency:
Multi-surface processing with one clamping: The five-axis freedom allows polishing of multiple angles and surfaces of the rearview mirror in one clamping, reducing the number of clamping times and auxiliary time.
Optimize the polishing path: CAM software can generate efficient and smooth tool paths, reduce empty travel, and shorten the single-piece processing time.
Automated Integration: Five-axis polishing machines are easy to integrate into automated production lines, and cooperate with robots for loading and unloading to achieve unmanned or less manned production.
4. Improve Surface Quality:
A constant optimal polishing angle and pressure are key to obtaining a uniform, high-gloss, defect-free surface. Five-axis technology directly solves this core problem on complex surfaces.
It can effectively reduce or eliminate surface defects such as orange peel texture, micro-scratches, and ripples, achieving a mirror or high-gloss effect.
