The Nachi MZ70F is a six-axis articulated industrial robot with a 70 kg payload and 2,102 mm maximum reach. It is intended for machine tending, material handling, palletizing, and dispensing. The robot has a hollow wrist for internal cable routing, IP67-equivalent protection, and a repeatability of ±0.06 mm.
Hollow wrist enables internal cable routing to reduce external interference.
Standard specification includes anti-corrosion treatment and anti-coolant coating.
General specifications list floor or inverted installation; additional information lists angle, cleanroom, floor, tabletop, and invert/ceiling mounting.
Air tubes are φ10x2 and application cables are 24 wires.
Position repeatability is stated as JIS B 8432 conformance.
Clean rating is equivalent to ISO Class 4 based on an internal assessment in accordance with ISO 14644-1.
Packaging is not dust-proof; clean the robot before bringing it into a cleanroom.
Maximum velocity values are stated to change with the operation program and wrist load condition.
The general specifications table lists model columns M235F-01, M250F-01, M270F-01, and M250LF-01.
The document also mentions MZ35F in a descriptive paragraph; no separate specification is provided.
Safety
Explosion-proof version is not available.
Wall and tilted mounting limit motion range; for wall mount axis 1 range is ±30°.
Fluids that cause deterioration of sealants, such as gasoline-based cutting fluids, chlorine, alkali, acids, and organic solvents, cannot be used.
The wire-harness portion is IP65 equivalent and the robot controller is IP20 equivalent.
Use at 1000 m or lower sea level; ambient temperature has limitations when allowable altitude is exceeded.
Ambient humidity must be 20-85%RH with no dew or frost; vibration must not exceed 0.5G (4.9 m/s²).
Noise is 80 dB(A) measured per JIS Z 8737-1 (ISO 11201) with maximum payload and maximum velocity.
