Titanium alloy mobile phone frame grinding and polishing
Double-sided grinding of titanium alloy phone frame
Double-sided grinding and thinning of the titanium alloy phone frame is a core precision process in manufacturing. The goal is to precisely machine the frame thickness to the design value (usually in the range of 0.3mm-1.0mm), while ensuring high planarity, low surface roughness, no burns, and stable material properties.
Equipment: High-precision double-end face grinding machine, with two grinding wheels rotating coaxially at high speed, and the workpiece passing through the wheels via a fixture (feed plate).
Advantages:
High efficiency: Double-sided processing is completed in one pass.
High parallelism: Synchronous grinding of the upper and lower grinding wheels ensures excellent parallelism of both sides (achievable to ±0.002mm).
Deformation control: The forces on both sides partially offset the grinding torque, reducing warping.
Polishing and grinding of titanium alloy phone frame
Titanium alloy frames have extremely high polishing requirements. The surface must be not only flawlessly smooth but also highly durable, able to withstand the friction and impacts of daily use. To meet this standard, our company uses a five-axis CNC polishing machine for grinding and polishing.
Five-axis polishing equipment
Features: Utilizing five-axis linkage technology, it allows for multi-angle, multi-station single clamping, capable of polishing and grinding various shapes such as planes, arcs, and 3D surfaces. Equipped with an exhaust dust removal system and an automatic waxing system, it supports dry polishing, wet polishing, and grinding. It also features polishing wheel compensation and dynamic pressure adjustment functions, ensuring polishing precision and quality.
Advantages: Compared to traditional polishing methods, five-axis polishing equipment improves production efficiency, reduces labor costs, and ensures consistent and stable polishing quality, especially suitable for polishing complex-shaped titanium alloy phone frames.
