Ball Bearing Assembly through Dual NACHI MZ07

Industry > MachineApplication > AssemblySector > Manufacturing

This is an automated assembly solution that replaces the manual ball bearing assembly process with two NACHI MZ07 high-speed robots.

By implementing an efficient system configuration, the cycle time has been minimized, and productivity has been significantly boosted through 100% inspection and continuous production. The high repeatability of the MZ07 ensures that the delicate components of the ball bearing are integrated with extreme precision.

Components

Robot	Robot: NACHI MZ07 (2 Units) Type: 6-axis articulated industrial robot Payload: 7kg Reach: 723mm (Horizontal) Weight: 36kg Repeatability: ±0.02mm (High-precision for assembly) Protection: IP67 (Dust and water-resistant)

Workflow

STEP 1.	Feeding: Input of the bearing's inner and outer rings.
STEP 2.	Inspection: Dimensional inspection of both the inner and outer rings.
STEP 3.	Coupling: Joining the inner and outer rings into position.
STEP 4.	Ball Insertion: Feeding and placing the steel balls into the bearing races.
STEP 5.	Discharge: Unloading the fully assembled bearing unit.

Key Features

Maximized Space Efficiency with Compact Robotics

Ultra-Compact Footprint: By utilizing small-scale industrial robots, the system can be installed in tight spaces equivalent to a human worker's station, avoiding the need for floor space expansion.

Reduced Production Time via High-Speed, High-Precision Performance

Industry-Leading Speed: With a standard reciprocating cycle time of only 0.31 seconds, the NACHI MZ07 enables exceptionally fast handling and assembly.
Micron-Level Precision: Maintains consistent quality even during high-speed operations, thanks to its superior repeatability.

Optimized Workflow through Dual-Robot Coordination

Multi-Tasking Excellence: Efficient tool design and workload distribution allow the two robots to simultaneously handle three different components, while performing inspection and assembly tasks in a single streamlined process.
