What are the differences between JW-U500 and JW-U640?

1. Structure & Use:
   1. The JW-U500 is a vertical structure, which is suitable for efficient machining of small and medium-sized workpieces.
   2. The JW-U640 is a gantry structure, which is suitable for larger sizes and heavier loads, especially machining scenarios that require high torque and high rigidity.
2. Performance Parameters:
   1. The JW-U640 has a higher spindle speed (15,000 rpm vs. 12,000 rpm), more motor power, and significantly higher torque for high-intensity machining.
   2. The JW-U500 has a faster fast traverse speed (30 m/min vs. 18 m/min) and is suitable for fast and light cutting.
3. Working range and load:
   1. The JW-U640 has a larger table (Φ400 mm vs. Φ350 mm), longer Y-axis travel (1,000 mm vs. 550 mm), and a higher load capacity (200 kg vs. 50 kg).
4. Chip evacuation and cooling:
   1. JW-U640 is equipped with a twin-screw chain chip conveyor for stronger chip conveyance.
5. Electricity Requirements:
   1. The JW-U640 has a higher total power capacity (36 kW vs. 20 kW) for higher power processing needs.

Suggestions for selection:

1. If you need to machine high-speed, small and medium-sized workpieces, JW-U500 is more suitable.
2. If you need large size, high load, high torque machining (such as large molds or heavy parts), JW-U640 is a better choice.
