Machine tending, grinding and handling, riveting and welding-these industrial applications never just require a robot that "works." Stability under high cycle rates, impact resistance during hard contact, and trajectory accuracy in complex poses-each of these tests the robot's mechanical rigidity, transmission efficiency, and control algorithms. Traditional solutions have long suffered from insufficient rigidity, trajectory jitter, and limited overload capacity when dealing with hard contact processes, restricting further improvements in production line efficiency and product quality.
The all-new CRP-RH19-25 industrial robot from CRP is a systematic answer to these challenges.
01 High-Rigidity Mechanical Solution for Hard Contact Applications
The newly launched CRP-RH19-25 is a high-rigidity 6-axis industrial robot designed for hard contact applications, featuring a 25kg payload, 1917mm reach, and ±0.05mm repeatability. In terms of structural design, the CRP-RH19-25 adopts a hypoid gear transmission technology, significantly improving the overload capacity of the entire unit.
The J4/J6 axes feature a φ57mm hollow structure for easy internal cabling, effectively reducing motion interference; the single-wrist design allows a J5 axis range of ±180°, easily handling large-pose and large-angle operation scenarios; the J1 and J2 axes feature a fully enclosed design for a higher protection level.
This model is widely applicable in machine tending, material handling, lightweight spot welding, riveting and welding, machining, and standard weld seam grinding.
02 Systematic Breakthroughs in Rigidity, Accuracy, and Speed
Part 01 Rigidity: The Backbone for Hard Contact Scenarios
Adopting a hypoid gear transmission technology route, the forearm rigidity is enhanced, and the overload capacity outperforms conventional models. When handling impact loads in hard contact scenarios, the CRP-RH19-25 demonstrates superior impact resistance and stability, providing reliable guarantees for high-rigidity applications like grinding and riveting.
Part 02 Accuracy: From ±0.05mm Repeatability to Superior Trajectory Performance
Repeatability is ±0.05mm; trajectory accuracy at a linear speed of 500mm/s is avg 0.2mm; dynamic TCP accuracy can reach 0.5mm. Combined with algorithmic accuracy compensation, trajectory precision is further optimized.
Part 03 Speed: Advanced Algorithms Unleashing Hardware Potential
Paired with high-speed motors on the J1-J3 axes and combined with advanced trajectory planning algorithms and jitter suppression technology, significant improvements are achieved in operating speed, short-distance acceleration/deceleration response, and trajectory stability. The maximum linear trajectory speed reaches 2500mm/s, with maximum speeds of 170°/s for J1/J2 axes and 200°/s for the J3 axis. Short-distance acceleration is faster, and jitter suppression is stronger.
03 Control Cabinet: Compact Design, Rich Integration
The CRP-RH19-25 is matched with the G9S control cabinet, featuring a single-phase AC220V power input. The cabinet structure is compact, reducing its footprint by 50% compared to the previous generation. In terms of interfaces, it integrates IO, digital, and analog interfaces, comes standard with EtherCAT master and Modbus protocols, and offers optional mainstream industrial communication protocols such as Profinet, CC-Link, and EtherNet/IP. It utilizes a quick-plug design for easier wiring.
The independent air duct design physically separates the power and control cavities, utilizing zonal cooling to effectively prevent thermal crosstalk and enhance dust resistance and anti-electromagnetic interference capabilities. Built-in multiple software and hardware safety mechanisms ensure stable equipment operation and reduce the risk of abnormal downtime. The cabinet protection level is IP54.
04 Typical Application Scenarios
Part 01 Weld Seam Grinding
The CRP-RH19-25, matched with floating force-controlled grinding, is applied to weld seam grinding, which demands high robot rigidity, trajectory accuracy, overload capacity, and protection. The high-rigidity forearm ensures stable grinding trajectories and effectively suppresses jitter; constant force control guarantees consistent results. The fully enclosed J1/J2 axis design minimizes the impact of the dust environment. Through full-pose hybrid force/position control compensation, the grinding tool can adaptively fit the curvature changes of the workpiece, ensuring grinding quality on complex surfaces. Matched with the Type E teach pendant, it improves teaching and programming efficiency.
Part 02 Foam Model Machining
Using offline software to quickly generate complex cutting trajectories, it overcomes programming difficulties like complex paths and frequent pose changes. Leveraging its high-rigidity body and advanced trajectory planning algorithms, the CRP-RH19-25 maintains trajectory accuracy at high speeds, effectively suppresses jitter, and produces clear cutting contours with neat edges.
Part 03 Riveting and Welding
A typical hard contact scenario with high impact loads. The hypoid gear transmission provides strong forearm rigidity and overload capacity superior to conventional models, ensuring riveting accuracy and consistency.
From the high-rigidity forearm to the hollow wrist, from hypoid gear transmission to the compact G9S control cabinet-the CRP-RH19-25 industrial robot continues to penetrate industrial scenarios like riveting and grinding, providing reliable technical solutions for hard contact processes. CRP will continue to drive product iteration, helping the manufacturing industry steadily advance toward high precision, high rigidity, and high efficiency.
