The Nachi MZ35F is a six-axis articulated industrial robot driven by AC servo motors, intended for machine tending, material handling, palletizing and dispensing. It has a 35 kg wrist payload and a 2102 mm maximum reach, with a hollow wrist that allows cables to be routed inside the arm. The body is rated IP67 equivalent and is supplied with anti-corrosion treatment and anti-coolant coating for wet or dirty work areas.
Specification table lists four model designations: M235F-01, M250F-01, M270F-01 and M250LF-01; payloads in those columns are 35 kg, 50 kg, 70 kg and 50 kg respectively, with reaches of 2102 mm or 2502 mm.
Structure is an articulated robot with AC servo motor drive.
Hollow wrist permits internal cable routing to reduce external interference and cable wear.
Air tubes are φ10x2 and the application cable bundle has 24 wires.
Installation is floor or inverted; motion range is limited for wall and tilted mounting (for example, axis 1 range is ±30° for wall mount).
Clean rating is equivalent to ISO Class 4, based on an internal assessment in accordance with ISO 14644-1.
Maximum static load torque: J4 and J5 165 N·m (216 N·m and 309 N·m in the higher-payload columns), J6 102 N·m.
Maximum moment of inertia: J4 and J5 16 kg·m², J6 5 kg·m² for the 35 kg column.
Position repeatability is stated per JIS B 8432.
Body weight is 5% lower and installation area 23% smaller than conventional models, per the document.
Noise level is 80 dB, A-weighted, measured under JIS Z 8737-1 (ISO 11201) at maximum payload and maximum velocity.
Applications listed: machine tending, material handling, palletizing, dispensing.
Safety
Protection class is IP67 equivalent; the wire-harness portion is IP65 equivalent and the robot controller is IP20 equivalent.
Explosion-proof version is not available.
Fluids that deteriorate sealants, such as gasoline-based cutting fluids, chlorine, alkali, acids and organic solvents, cannot be used.
Ambient temperature limit is 0 to 45 °C and ambient humidity 20 to 85 %RH with no dew or frost allowed.
Vibration at the mounting must not exceed 0.5 G (4.9 m/s²).
Use is limited to altitudes of 1000 m or lower; ambient temperature has limitations above the allowable altitude.
For cleanroom use the robot must be installed in a down-flow type cleanroom, and the packaging is not dust proof, so the robot must be wiped or cleaned of particles before entry.
Motion range is restricted when wall mounted or tilted mounted (axis 1 is ±30° for wall mount).
Use for military purposes or weapon production may make the product subject to export restrictions under the Foreign Exchange and Foreign Trade Act.
