2025-11-21

This company is a manufacturer of 3C electronic components in Southeast Asia, primarily supplying core components such as phone frames and casings to international brands including Apple and Samsung. Previously, due to insufficient precision and low efficiency of its machining equipment, the company faced significant challenges: a high defect rate in curved surface processing (reaching as much as 5%) and long delivery cycles. It urgently needs high-performance drilling and milling equipment to break through production bottlenecks.

Customer Background

Customer needs

1. Machine the curved surface of the phone’s middle frame (material: 6061 aluminum alloy). The profile error of the curved surface must be ≤ ±0.003 mm, and the surface finish must reach Ra ≤ 0.4 μm.

2. Single-shift production capacity needs to be increased to over 800 units to meet the delivery requirements of bulk orders.

3. The equipment must be compatible with automated production lines to reduce labor costs.

Tico Solutions

Customized integrated machining solution for customers: “TL740 Drilling and Tapping Machine + Automatic Loading and Unloading Robotic Arm.”

1. Equipment Selection: The TL740 drilling and tapping machine is equipped with a high-speed spindle capable of 24,000 rpm and features a rapid traverse rate of 60 m/min. It is paired with the Dike-CNC intelligent CNC system, which supports surface machining trajectory simulation and real-time error compensation.

2. Process Optimization: Based on the characteristics of 6061 aluminum alloy, optimize cutting parameters (cutting speed: 120 m/min; feed rate: 0.1 mm/r). Equip with a high-pressure internal cooling system (70 bar) to prevent machining chips from scratching the curved surface.

3. Automation Integration: Connect to the customer’s existing MES system and use an automated loading/unloading robotic arm to achieve unmanned operation—“raw material loading – processing – finished product unloading”—thus reducing manual intervention.

Implementation effect

1. Compliance with Precision Standards: After machining, the surface contour error of the phone’s middle frame remains stable within ±0.002 mm, and the surface finish achieves an Ra value of 0.4 μm, eliminating the need for subsequent polishing. The defect rate has dropped from 5% to 0.8%.

2. Efficiency Improvement: Single-shift production capacity has increased from the original 600 units to 850 units, representing a 42% increase in production efficiency and a 30% reduction in delivery cycle.

3. Cost Reduction: After the automation upgrade, each production line has seen a reduction of two workers, resulting in annual labor cost savings of approximately 150,000 yuan (calculated based on local wage standards).

Customer reviews

“The high precision and efficiency of the Tico TL740 drilling and tapping machine have exceeded our expectations. Not only has it addressed the core pain points in our curved-surface machining, but it has also helped us upgrade our production line to full automation, providing a solid foundation for taking on large orders from international brands,” said the company’s Production Director.
