Delta CNC Solution for Smart Device Shell Processing

Smart devices such as smart phones and tablets have made our lives more convenient. To many consumers, smart devices are more than just communication tools, but also symbols of taste and personality. Consumers desire many unique products and accessories, which encourages manufacturers to improve product quality and equipment performance.

Delta Industrial Automation recently helped a customer in Dongguan, China, that manufactures the aluminum cases for smart devices. Delta provided the customer with a complete CNC solution for chamfer processing on a dual-axis highlight engraving and milling machine. The CNC solution successfully delivered a highly efficient, high performance machine tool system for the customer, improving their production efficiency and reducing the defect rate.

The customer's machine tools require advanced technologies, high processing speed for the numerical system, and prompt servo motor response to perform both carving and engraving processes. Delta's CNC solution integrates its CNC Controller NC300 Series, AC motor drive, and AC servo drive and motors.

When processing chamfers on aluminum cases, Delta's CNC solution performs high-speed and highly precise logical motion calculations and transmits the calculation results and operation orders to the AC servo drives of the ASDA-A2 Series via Delta's high-speed communication system DMCNET (frequency: 1ms). The ASDA-A2 Series then controls the AC servo motors of the ECMA Series to precisely perform engraving and milling, and pass operation data back to the main controller via two-way high-speed data transfer.

The ASDA-A2 Series has excellent motion control functions and conducts steady acceleration and deceleration control, and the ECMA Series implements 20-bit (1,280,000 p/rev) superior resolution encoder. Together, the ASDA-A2 Series and the ECMA Series assure smooth machine operation, a high precision carving process, best product quality, and a low defect rate.

In addition, Delta adopts an AC motor drive of the VFD-C200 Series to control the machine tool's spindle. The VFD-C200 Series transfers the analog data sent from the CNC controller for a corresponding speed, making sure the spindle operates steadily at high speed. This helps the machine tool maintain normal operation.

Delta's CNC solution has a simple structure and rapid communication system. It is highly integrated, steady, and reliable, and provides high precision, high efficiency and best product quality for the customer. Widely praised by customers, Delta's IABG continues to provide highly effective solutions that increase customer competitiveness.
