Metal Machining Assistance for Two WIA Turning Centers using Hyundai Robots

Industry > Metal·PlasticsApplication > Machine TendingSector > Manufacturing

This machine tending solution utilizes a Hyundai HH7 robot mounted on a linear track (7th axis) to assist metal machining across two WIA Turning Centers (HD2200Y).

By leveraging a compact industrial robot and an additional 7th axis, the footprint required for automation is minimized. To ensure operator safety, an integrated robot safety fence was applied, and sensors were installed to decelerate or stop the robot upon detecting human proximity. Furthermore, the automation of both pre- and post-processing via conveyors enables 24-hour unmanned continuous production.

Components

Robot	Robot: Hyundai HH7 6-axis articulated robot, payload 7kg, reach 932mm, weight 42kg, repeatability ±0.03mm. Additional Axis: Linear track integration (7th axis) for multi-machine coverage.

Workflow

STEP 1.	Feeding & Alignment: A 2-axis Cartesian robot picks the raw workpiece from the input conveyor and moves it to the alignment device.
STEP 2.	Picking: The Hyundai HH7 robot picks the aligned workpiece.
STEP 3.	Transfer: The robot moves along the linear track to the target Turning Center.
STEP 4.	Loading/Unloading: The robot picks the finished part from the CNC and loads the new raw workpiece.
STEP 5.	Machining: The Turning Center begins the machining process.
STEP 6.	Discharge: The finished part is transferred to the discharge conveyor.

Features

Improved Productivity and Operational Efficiency

Cycle Time Minimization: Utilizes high-speed, high-precision industrial robots to ensure the fastest possible processing times.

Optimized Utility: A single robot serves two machine tools, matching machining times to minimize idle periods.

Scalable Layout: The system configuration can be expanded or modified based on the number of processing machines.

Continuous Production: Integrated input/output conveyors minimize management intervention and enable seamless 24/7 operation.

Custom Tooling: End-of-arm tooling (grippers) can be custom-designed and manufactured to meet specific workpiece requirements and performance goals.

Simultaneous Safety and High Space Utilization

Space Maximization: Minimizes the occupied area in front of machine tools, allowing for a highly efficient floor plan.

Redundant Safety Systems: Dual-layered operator protection ensures a secure working environment.

Integrated Safety Barrier: Protective walls are installed directly on the robot base to secure the workspace during operation.

Intelligent Motion Control: Worker detection sensors are mounted on the linear rail, automatically decelerating or stopping the robot if a person approaches.
