What is it?
The Nachi MZ04 is a 6-axis industrial robot with 4 kg payload, 550 mm reach, and ±0.02 mm repeatability. The smallest articulated robot in Nachi's MZ-series, the MZ04 is optimised for maximum cycle speed in compact electronics and precision assembly applications. Its 0.3-second cycle time on a standard test path makes it one of the fastest robots in the 4 kg class.
Who is it for?
- Electronics manufacturers running high-speed PCB component insertion and board handling at maximum throughput
- Automotive electronics suppliers assembling sensors, connectors, and ECU components at high cycle rates
- Medical device manufacturers requiring cleanroom-certified robots for precision assembly and inspection
- Semiconductor and optical equipment manufacturers needing sub-0.02 mm precision in compact cells
Key specs
- Payload: 4 kg
- Reach: 550 mm
- Repeatability: ±0.02 mm
- Degrees of freedom: 6
- Weight (arm): 19 kg
- Cycle time: 0.3 s (25 mm up/down/across)
- Controller: Nachi FD
- Configuration: Floor, inverted, wall; cleanroom option
How it compares
The Comau Racer3 (3 kg, 630 mm, ±0.02 mm) is the closest class competitor, with slightly lower payload and longer reach. The Fanuc M-1iA/0.5S (0.5 kg, 280 mm) targets smaller payloads. The MZ04 leads at 4 kg compact assembly for applications where the Racer3's 3 kg is insufficient and Nachi's automotive parts and service network is advantageous.
Limitations
- Not collaborative; full safety guarding required for all deployments
- 550 mm reach limits to compact bench-top cells; cannot service wide or elevated fixtures
- Nachi's integrator network is smaller in Western markets than Fanuc, KUKA, or ABB
- FD controller programming has a steeper learning curve outside Nachi-trained integrators
