Manufacturing Process

01.

CNC Machining

Main structural housings are milled from solid Al 7075-T6 billets using 5-axis DMG MORI machining centers to maintain positional tolerances within +/- 0.005 mm.

02.

Surface Treatment

Hard anodizing (Type III, thickness >= 50 um) applied to all exposed aluminum surfaces for abrasion and corrosion resistance.

03.

Harmonic Drive Fitting

Gearboxes are assembled in a temperature-controlled cleanroom (ISO Class 7) with controlled preload torque using specialized torque-monitoring drivers.

04.

Internal Cable Routing

Hollow-shaft joint design routes power and signal lines internally, preventing cable fatigue and external snagging during continuous 360-degree rotation.

Key Features / Capabilities

True Torque Sensing

Direct-drive torque sensors on all six joints enable real-time collaborative safety stop and compliant force-control teaching.

High Payload-to-Weight Ratio

1:0.35 payload-to-arm-weight ratio reduces dynamic load on mounting fixtures and mobile bases.

Open Control Architecture

Linux-based real-time controller supporting custom kinematics, C++/Python APIs, and third-party end-effector plug-ins.

Tool Flange Utility

Integrated ISO mechanical flange with pass-through pneumatic lines (2x 4 mm) and electrical M8 8-pin interface for gripper power and signal.

Applications

Precision Assembly

Fast insertion, screw driving, and micro-component handling in electronics manufacturing.
CNC Machine Tending

Automated loading and unloading of vertical and horizontal machining centers.
Dispensing & Sealing

Continuous path trajectory control for bead dispensing, gluing, and potting applications.

FAQ

Q: What industrial communication protocols and software environments are supported for integration?

A: The controller supports EtherCAT, PROFINET, Modbus TCP, and TCP/IP sockets. For software development, the open-source ROS2 (Robot Operating System) ecosystem, C++ SDK, and Python API are fully supported, allowing direct trajectory control and sensor integration without proprietary lock-in.

Q: How is collision detection handled during collaborative operation?

A: Integrated dual-channel torque sensors on every joint continuously monitor motor current and torque feedback against dynamic gravitational and inertial models. Upon detecting an external force exceeding the user-defined threshold (> 10 N to 150 N configurable), the controller cuts power and halts movement within 10 milliseconds, compliant with ISO 10218-1 and ISO/TS 15066 safety standards.

Q: What is the expected maintenance interval and how are worn components serviced?

A: Routine maintenance requires visual inspection of cabling and flange fasteners every 2,000 operational hours. Harmonic drive gearboxes are factory-lubricated for 20,000 hours. The modular joint design allows technicians to swap an individual joint module within 45 minutes using standard alignment tooling, eliminating the need to return the entire arm to the factory.

Q: Can the robot arm operate on mobile platforms like AGVs or AMRs?

A: Yes. The arm's low weight (14.5 kg for the 5kg model) and low power consumption (24V - 48V DC direct battery input option) make it suitable for mobile robotic applications. The controller accepts external odometry inputs and supports dynamic base compensation algorithms to maintain end-effector accuracy while the mobile base is stationary.

Q: What documentation and testing data are provided prior to shipment?

A: Every unit undergoes laser tracker verification and a 72-hour burn-in test. Shipments include the individual Factory Acceptance Test (FAT) report detailing exact repeatability measurements, electrical safety test certificates, STEP 3D CAD files, and complete API/integration programming manuals.

Q: What is the standard procedure and timeline for requesting a customized kinematic prototype?

A: The process begins with sharing your workspace envelope, payload requirement, and cycle time targets. Our engineering team reviews the kinematic feasibility within 48 hours. Upon signing an agreement, initial concept designs and CAD models are delivered in 2 weeks, and functional prototypes are manufactured, calibrated, and shipped within 6 to 8 weeks.
