JCL-S500 Technical Deep Dive: Precision Desktop Piezoelectric Dispensing
1. Motion Architecture & Structural Rigidity
The system is built upon a welded, integrally formed machine frame to ensure maximum dampening and long-term mechanical stability.
-
Drive System: The XY-axis utilizes linear motors paired with linear encoders (grating scales) for closed-loop feedback, while the Z-axis is driven by a high-precision servo motor.
-
Kinematics: Features a maximum XY velocity of 1500 mm/s and acceleration of 1.5 G.
-
Precision: Delivers a repeat positioning accuracy of ±0.003 mm for XY and ±0.02 mm for Z.

5. FAQ: Operational Integration
What are the power and grid requirements for the JCL-S500?
The system operates on Single-phase AC 220V (50/60 Hz) with a total power consumption of 1.5 kW. To ensure electronics longevity, the grid fluctuation must remain within < ±10%.
What environmental controls are necessary for high-precision dispensing?
Stability is critical. The operating environment must be maintained between 5°C and 30°C with temperature fluctuations limited to ±2°C. Humidity should be controlled within 45%–75%.
How should the compressed air supply be configured?
The equipment requires an input pressure of 0.5–1.2 MPa at a flow rate of ≥ 50 L/min. Crucially, compressed air must be dewatered and deoiled, then passed through an air dryer before entering the machine.
Can the piezoelectric valve be easily maintained?
Yes. The nozzle and needle assembly are designed to support quick disassembly and assembly, reducing downtime during fluid changeovers or cleaning.
