When the Nachi-Fujikoshi MZ07 industrial robot swings into motion, its slim orange arm passes just a few centimeters from the safety fence without a wobble. You can almost hear production engineer Satoshi Tanaka exhale when the gripper places yet another metal part exactly in its tray.
What the MZ07 is built for
The Nachi-Fujikoshi MZ07 is a compact 6-axis industrial robot with a maximum payload of 7 kg and a reach of around 723 mm. It targets tasks such as machine tending, small-parts handling, assembly, and simple packaging lines in cramped factory cells.
According to the official product documentation, the arm weighs about 30 kg and offers repeatability of ±0.02 mm, which puts it in the precision range demanded by automotive and electronics suppliers. Nachi highlights the very small interference radius, which helps integrators pack several MZ07 units tightly around a conveyor.
Design, cabling and protection
In person, integrators notice how tidy the MZ07 looks. Most cables run internally through the arm, so there is less risk of snagging, and the smooth outer surfaces wipe clean with a cloth at the end of a shift. Nachi specifies an IP67 rating for the wrist, allowing use in environments with coolant spray or fine dust.
The base footprint is small, which lets integrators mount the robot on narrow pedestals or even hang it from frames above the line. Systems engineer Yuki Nakamura from a mid-size supplier in Aichi Prefecture describes the robot as a good fit for retrofitting older manual workstations that offer little spare floor space.
Background on Nachi-Fujikoshi Corp shares
The MZ07 robot is part of Nachi-Fujikoshi Corp's broader motion control portfolio, which investors follow alongside the company’s bearings and cutting tools business.
Speed, cycle times and safety
Nachi claims joint speeds up to 520 degrees per second for some axes, allowing short cycle times on repetitive pick-and-place tasks. Integrators using the current NX series controller report that the combination can achieve smooth paths even at higher speeds, as long as payload and inertia limits are respected.
The MZ07 supports standard safety functions via the controller, including emergency stop circuits and safety-rated monitored stops. For more advanced needs, system builders typically add external safety PLCs, scanners or light curtains. The arm itself is not a collaborative design; fences and guarding remain mandatory in typical automotive deployments.
Programming and everyday handling
On the shop floor, the first contact is often the teach pendant. Operators face a color touchscreen with hard keys for jogging and emergency stop, plus menu structures that resemble earlier Nachi generations. Reports from Japanese integrators suggest that technicians familiar with older Nachi robots can adapt quickly.
For new users, the learning curve is steeper than with tablet-like cobot interfaces, but once basic joint moves and frames are set up, point teaching with the pendant becomes routine. CAD-based offline programming and simulation are available for engineering teams that build more complex cells.
Where the compact arm fits
The MZ07 competes with other compact 6-axis robots from Japanese and European manufacturers in the 5 to 7 kg class. Its strengths are the small interference radius, the relatively light arm and the sealed wrist, which suit cramped dirty environments such as coolant-sprayed machine tools.
By contrast, buyers looking for safe human-robot collaboration may prefer a cobot with integrated force limiting instead of the traditional fenced setup. Still, in fully enclosed cells in automotive or metalworking plants, integrators often favor the robustness and cycle-time focus of conventional industrial arms like the MZ07.
Context and share reference
Nachi-Fujikoshi Corp positions robots such as the MZ07 alongside bearings, hydraulic equipment and cutting tools as part of an integrated offering for factory automation customers. Nachi-Fujikoshi Corp shares (ISIN JP3642000003) trade on the Tokyo Stock Exchange, giving investors direct exposure to this automation and components mix.
