CNC Machine Tending Robot

 

The CNC Machine Tending Robot system is an automated material handling workstation designed for CNC machine tools (lathes and machining centers). Built around a six-axis industrial robot, the system integrates customized end-of-arm tooling (EOAT), part staging trays, turnover units, and an industrial electric control cabinet.

 

 

This robot is suitable for CNC automation in the following production conditions.

CNC lathe / turning center continuous production
Single-machine or multi-machine (1-to-2 / 1-to-3) production cell
Medium batch or high repeatability machining parts
Stable cycle-time machining processes
8–24-hour continuous production environments

 

 

• Dual pneumatic grippers exchange raw and finished parts in one machine entry, reducing door-open time.
• ±0.05 mm repeatability supports accurate workpiece positioning for chuck or vise loading.
• IP54-rated wrist protection and oil-resistant cables help resist coolant and metal chips.
• Pilot-operated check valves help maintain gripper pressure during air supply loss.

Every machine tending workstation undergoes full factory testing before shipment:

Mechanical & Pneumatic Assembly Inspection: Fastener torque checks on mounting bases and high-pressure leak testing on all pneumatic lines.

Electrical & Signal Continuity Checks: Point-to-point I/O wiring validation and emergency stop loop safety response tests.

Trajectory & Interference Simulation: Dry-run motion programming and collision testing using mock machine tool interface frames at our facility.

72-Hour Endurance Testing: Continuous 72-hour cycle testing under full nominal load to verify thermal drive stability, pick repeatability, and fault recovery routines.

Quality Documentation Package: Shipped with electrical schematics, PLC I/O mapping tables, mechanical BOMs, and user operation manuals.

 

 

On-Site Commissioning: Mechanical installation, PLC wiring, signal calibration, and production ramp-up.

Training & Documentation: Operator training, program switching, robot teaching, maintenance guidance, and English manuals, wiring diagrams, and I/O maps.

After-Sales Support: Remote technical assistance, spare parts supply, and a standard 12-month core component warranty.

Site Preparation: Customers must provide three-phase power, clean, dry compressed air (≥0.6 MPa), a level concrete floor, and accessible machine interfaces.
