As a commonly used linear motion component in the field of industrial automation, the performance testing of TOYO (Toyo Automation) modules focuses on core dimensions such as precision, speed, load, rigidity, and stability. Products of different series (such as ball screw-driven, belt-driven, built-in sliding tables, etc.) have their own emphases in actual testing. The following is a detailed analysis combined with test data of specific models and application scenarios:
Positioning accuracy is the core advantage of TOYO modules. The performance of different drive methods and models in actual tests is as follows:
Ball Screw-driven Series (GTH4/GTH5):
GTH4 Series (Built-in Rail Type): The repeat positioning accuracy of the C5 ground-grade ball screw is measured to be ±0.003mm, and that of the C7 rolled-grade is ±0.005mm. The equal-height straightness error is ≤±0.02mm (achieved through the grinding process after embedding the rail into the main body).
GTH5 Series: The repeat positioning accuracy is stably maintained at ±0.005mm. Even when the stroke reaches 800mm, the ball screw deflection is controlled within an extremely small range (the speed needs to be reduced as required). After tens of thousands of cycles of movement, the precision attenuation rate is less than 5%, which is far better than the attenuation level of more than 10% of similar domestic products.
Rack and Pinion Sliding Table Series (ETK15): In long-stroke scenarios (maximum 5.7 meters), the measured repeat positioning accuracy is ±0.08mm. The high torsion resistance of the gear mechanism ensures micron-level positioning capability even during long-stroke operation.
Belt-driven Series: Although the positioning accuracy is slightly lower than that of the ball screw-driven type, the measured repeat positioning accuracy is ≤±0.05mm, which meets the requirements of long-distance transportation, spraying and other scenarios, and has outstanding speed advantages.
High-speed Performance Test:
Belt-driven Modules: The maximum speed can reach 5m/s with an acceleration of 50m/s², far exceeding the average level of similar products. In scenarios such as food packaging and logistics sorting, the measured single-cycle transportation time is shortened by more than 30% compared with similar products.
Ball Screw-driven Modules: The maximum speed of the GTH8 Series is 1200mm/s, the GTH5 Series (20mm lead) is 1000mm/s, and the GTH4 Series (10mm lead) is 600mm/s. The acceleration ranges from 0.3G to 0.6G, and the start-up response time is ≤0.2 seconds.
Long-stroke Speed Stability: For the ETK15 rack and pinion sliding table with a 5.7-meter stroke, the maximum speed can still reach 1132-1509mm/s, the speed fluctuation during operation is ≤±2%, and there is no obvious jamming or deceleration.
Horizontal Load: The maximum horizontal load capacity of the ETK15 Series is 53kg, the GTH5 Series (Model L2) is 30kg, and the GTH4 Series (Model L2) is 25kg. In the test, continuous operation for 8 hours under rated load shows no deformation of the module and no significant decrease in transmission efficiency.
Vertical Load: The vertical load capacity of the ETK15 Series is 16kg, the GTH5 Series (Model L2) is 10kg, and the GTH4 Series (Model L2) is 8kg. With a braking device, the vertically suspended load shows no settlement after 24 hours of standing and no slipping during start-up.
Rated Thrust: The rated thrust of the GTH5 Series (Model L2) is 854N, and the maximum rated thrust of the ETK15 Series is 368N. In the test, when pushing rigid loads, the thrust output is uniform without impact, meeting the requirements of precision press-fitting, clamping and other scenarios.
Rigidity Test: The integrated steel structure design of the main body and sliding seat (GTH Series) has a torsional stiffness increased by more than 40% compared with traditional aluminum sliding seats. Under 1.5 times the rated load, the module deflection is ≤0.01mm, which is suitable for high-precision load scenarios such as engine block inspection, with minimal repeatability error of detection data.
Operational Stability: The measured Mean Time Between Failures (MTBF) is more than 50,000 hours, and the joint life exceeds 100,000 hours. In 3C product assembly lines, continuous 24/7 operation for 365 days results in a failure rate of less than 0.5%. The dust-proof design (special steel belt structure) meets the CLASS1000 cleanroom standard in tests, producing no dust in semiconductor and medical device production.
Mobile Phone Screen Lamination: Using the GTH5 Module, the measured lamination accuracy error is ≤±0.01mm, the bubble-free rate reaches 99.8%, the production cycle is improved by 25% compared with traditional modules, and the precision attenuation is less than 3% after tens of thousands of lamination operations.
Chip Packaging: The multi-axis combined module (XY-axis) has a measured positioning accuracy of ±0.005mm, which can accurately complete gold wire bonding. The pin soldering yield is increased to 99.9%, meeting the mounting requirements for ultra-small chip pin spacing (≤0.1mm).
Engine Block Inspection: The ETK15 long-stroke module drives the detection probe to move. The measured dimensional measurement error is ≤±0.008mm, and the repeatability error of surface roughness detection is ≤0.02μm, providing reliable data support for quality inspection.
Component Transportation: In automotive component transfer devices, the belt-driven module increases the single-batch transportation efficiency by 40% in tests, with a positioning error of ≤±0.03mm for long-distance (3 meters) transportation, meeting the requirements of high-cycle production lines.
Syringe Assembly: The GTH Series dust-free module operates without dust pollution in cleanroom environments in tests. The component assembly position error is ≤±0.02mm, the product qualification rate is increased to 99.5%, complying with medical-grade production standards.
Optical Lens Grinding: Using the GTH4 C5-grade module, the measured sub-micron displacement control (≤0.1μm), the lens curvature accuracy error is ≤±0.002mm, and the surface finish Ra is ≤0.01μm, meeting the manufacturing requirements of high-end optical instruments.
Excellent Precision Retention: After long-term cycle tests, the precision attenuation rate is low, superior to similar domestic products.
Balanced Speed and Load: The belt-driven series balances high speed and long stroke, while the ball screw-driven series balances high precision and high rigidity.
Easy Installation and Maintenance: Supports multi-directional installation (horizontal, vertical, inverted). The external oil injection design eliminates the need to disassemble the sliding seat, extending the maintenance cycle by 30%.
Miniaturization and Space Adaptability: The built-in rail design (GTH Series) reduces space occupation by 20% compared with traditional modules, suitable for operations in narrow spaces (such as 3C product assembly lines).
Long-stroke Usage: When using with long strokes (e.g., ETK15 stroke exceeding 5.7 meters, GTH5 stroke exceeding 600mm), the speed must be reduced to avoid ball screw deflection, otherwise precision will decrease.
Installation Surface Requirements: The installation surface must be flat and firm; otherwise, the equal-height straightness will be affected. It is recommended that the flatness error of the installation surface be ≤0.02mm/m.
Vertical Installation: A braking device must be equipped for vertical installation to prevent load slipping.
Selection of Ball Screw Grades: Different ball screw grades (C5/C7) are suitable for different scenarios. For high-precision scenarios (such as semiconductor manufacturing), the C5 ground-grade is recommended; for general scenarios, the C7 rolled-grade can be selected to balance cost and performance.
