GR680-2700 model positioning and working condition adaptation
GR680-2700 It belongs to the EFORT GR series spraying robot, with a rated load of 8kg and a motion radius of 2715mm. EFORT's technical foundation is the acquisition of Italy's EVOLUT (integrated) and WFC (woodworking), with mature spraying and general handling process packages; The control platform is an M-type control cabinet, and the program ecosystem consists of graphical programming + process package calling.
From the perspective of working condition adaptation, typical applications for light loads (8kg) positioning are:Machine tool loading and unloading, 3C assembly, inspection, and handling of small and medium-sized partsCommon application processes for this model include painting, painting, and gluing. The extra-long boom (2715mm) is suitable for large workpieces and cross-line services, with attention to rigidity and vibration during large overhang postures. The end fixture is counted as a load from the most important point—the total of gripper + workpiece + sensor should not exceed 80% of the rated value. Workpieces with high inertia (long rod/uneven load) should be checked separately.
| Parameters | Engineering interpretation and usage recommendations |
|---|---|
| Rated load 8kg | It is recommended to reserve a load margin of 20%–30%; Verification is made by combining end self-weight + workpiece + imbalanced load inertia, especially sensitive to high-speed conditions |
| Movement radius: 2715mm | Determine the radius of the workcell layout: bins, tooling, and fences are bounded by maximum arm span + safety distance; Verify the accessibility of each pick-and-place point during cross-station service |
| Number of axes: 6 | Six-axis all-posture capability, the preferred choice for complex trajectory and inclined surface operations |
| Controller: M-type control cabinet | Decide on the process ecosystem, spare parts channels, and second-hand residual value; Currently, spare parts channels are smooth, and repair and upgrade paths are mature |
Control systems and common failure modes
The MR680-2700 comes with an M-type control cabinet controller, with a programming language and development environment of graphical programming + process package calls. Maintenance of this generation of control platforms focuses on three basic components: power, storage, and cooling—most "sudden downtime" can be detected in advance when preventive maintenance is in place.
| Failure mode | Typical performance | Disposal recommendations |
|---|---|---|
| Driver alarm and encoder abnormality | Driver alarm and encoder abnormality | Included as a mandatory inspection item for annual maintenance, with spare parts stocked in advance |
| Explosion-proof parts of spraying machine models are aging | Explosion-proof parts of spraying models aged (sealing and grounding) | Initial interpretation of alarm codes by reference with manuals, remote diagnosis allows for early positioning |
| The teach pendant malfunctioned | The teach pendant malfunctioned | Daily inspection coverage, with abnormal trends (abnormal noises/temperature rise/errors) recorded |
| Communication between IO and bus is abnormal | Communication between IO and bus is abnormal | Quarterly dust removal maintenance and cabinet temperature monitoring |
| Maintenance projects | Cycle recommendations | Key points |
|---|---|---|
| Spray explosion-proof models undergo annual inspection according to explosion-proof regulations (grounding, sealing, certification effectiveness). | According to the manufacturer's manual cycle | Spray explosion-proof models undergo annual inspection according to explosion-proof regulations (grounding, sealing, certification effectiveness). |
| Routine management of batteries and lubrication | According to the manufacturer's manual cycle | Routine management of batteries and lubrication |
| Program parameters are backed up regularly | Periodically | Program parameters are backed up regularly |
| Cable and drag chain inspection | every six months | Insulation, shielding, and bending radius inspection of power and encoder lines, as well as wear of cables inside the drag chain, are the main causes of intermittent faults |
| Zero point and accuracy retest | Every year | Repeatability measured by dial gauges or laser trackers, drift trend digitization—accuracy degradation can be seen six months in advance |
| Control cabinet dust removal and fans | Every quarter | Filter cleaning, fan speed and noise checks, cabinet temperature recording; Dust environments shorten the cycle |
Henghuan's service capabilities for GR680-2700
This site is a third-party robotics technology service provider. The GR680-2700 supports eight major business services (sorted by service frequency for each model):
- Maintenance and repair: For the on-site diagnosis, board-level maintenance, and annual maintenance contract for GR680-2700—for sprayed explosion-proof models, we follow SOPs for annual inspection (grounding, sealing, certification effectiveness) and other brand-exclusive items according to explosion-proof regulations, and we respond on the same day as Sichuan-Chongqing.
- Used & in-stock robot sales: Second-hand circulation is increasing, and the procurement of spray painting models requires verification of explosion-proof certification documents; Inventory GR680-2700 or equivalent models come with a full-function test report and a 12-month warranty.
- Sales of new industrial robots: When adding new production lines or replacing batches, we conduct cross-brand selection comparisons based on process requirements (including models of the same class as EFORT), and provide configuration and pricing plans.
- Applied technology services: Process programming, trajectory optimization, tap time potential, and model change formula management for the GR680-2700, with targeted tuning according to painting, painting, and gluing conditions.

Common issues with this device
Is it easy to find spare parts for the GR680-2700?
EFORT: The spare parts channel for this generation is smooth; we have in-stock or short-cycle channels for standard parts such as drivers, power modules, batteries, and teach pendant components; For sprayed explosion-proof models, it is recommended to configure consumables for annual inspection (grounding, sealing, certification effectiveness) according to explosion-proof regulations according to the annual maintenance contract.
With a nominal load of 8kg, how much weight can it actually handle?
The rated load is the static load limit of the flange surface. In actual selection, three factors must be considered: the self-weight of the end fixture (vacuum suction cup groups or grippers often account for 2–5kg), the inertia generated by the workpiece offload (checked according to the inertia ratio when the center of gravity deviates from the flange center), and the dynamic load during high-speed movement. The conventional engineering practice is to keep the "end + workpiece" within 70%–80% of the rated value to ensure cycle time and service life.
If the equipment's accuracy deteriorates after several years of use, how can it be restored?
According to the inspection order: first check whether the zero point is drifting (common after collision or battery depletion), then perform zero calibration; Check the reducer's return error (actual measurement of forward and reverse positioning deviation; if exceeded, disassemble or replace); Then check the installation base fastening and foundation settlement; Finally, trajectory compensation parameter restructuring. Most accuracy issues can be mostly restored after calibration and maintenance, so there is no need to rush into major repairs—we first release the inspection data before deciding on the plan.
Is the used GR680-2700 worth buying?
With the increasing circulation of second-hand products, it is necessary to verify explosion-proof certification documents when purchasing spray painting models. Three essential items for second-hand procurement: comprehensive inspection reports (axial accuracy, driver status, insulation and battery), maintenance history and operating hours, controller generation, and software license integrity. Every used machine we sell comes with inspection records and a 12-month warranty, and we can also accept third-party inspections designated by customers.
