Gruvmaster RG-4X Pro: Structural Updates Based on the RG-4X
publisherRUBR
time2026/01/05
- This article explains the structural updates of the Gruvmaster RG-4X Pro based on the RG-4X. The upgrades focus on practical improvements, including a frame with integrated storage, a larger grooving assembly, reinforced pipe support, and upgraded positioning rollers. These changes enhance stability, durability, and control during long-term roll grooving operations.
Building on the experience of using the RG-4X, Gruvmaster made several structural adjustments focused on real-world use, resulting in the RG-4X Pro.
These changes are not about adding new functions, but about improving stability, durability, and details that become noticeable during long-term operation.
Compared with the RG-4X, the RG-4X Pro mainly differs in the following areas.
1. Frame Upgrade with Integrated Storage Box
The RG-4X Pro replaces the original support legs with a frame structure that includes a built-in storage box.
This change improves overall machine stability while also providing space for commonly used tools and accessories on site.
In daily use, this type of structure helps keep the working area more organized and reduces unnecessary handling during operation.
2. Larger Grooving Assembly
On the RG-4X Pro, the grooving assembly has been upgraded to a larger-size structure.
The increased size helps maintain more stable load distribution during grooving, contributing to improved durability and more consistent control of pipe-end flaring.
This adjustment is mainly intended for applications with higher usage frequency and heavier working conditions.
3. Reinforced and Thickened Pipe Support
The pipe support on the RG-4X Pro has been fully reinforced and thickened.
This makes it more suitable for long-term, continuous heavy-duty use and helps maintain stable pipe support during the grooving process.
When handling longer or heavier pipes, this structural change is easier for operators to notice in practice.
4. Upgraded Positioning Rollers to Reduce Pipe Movement
Pipe movement during grooving is a common factor affecting processing stability.
The RG-4X Pro adopts reinforced positioning rollers to more effectively limit pipe deviation during operation.
This upgrade does not change the basic operating method, but helps reduce pipe movement and makes the grooving process more controllable.
Summary
Compared with the RG-4X, the updates on the Gruvmaster RG-4X Pro are concentrated at the structural level:
a more stable frame design, a more durable grooving assembly, stronger pipe support, and more reliable positioning.
These changes do not alter the fundamental working principle of the roll grooving machine. Instead, they reflect targeted adjustments based on repeated, practical requirements encountered during long-term use.
