A recent batch of Gruvmaster roll grooving machines has completed final assembly and shipment preparation.

The photos document the real process from workshop assembly to wooden crate packaging, reflecting our standard inspection, packing procedures, and current delivery operations.

The CM-12 is an electric hydraulic pipe cutting machine designed for cold cutting of 2"–12" steel and stainless steel pipes. It is mainly used in fixed or semi-fixed working areas such as workshops. With a split hydraulic system, pipe support stand, and durable cutting blade, the CM-12 provides stable and straightforward cutting for daily use.

This article documents a practical evaluation of a pipe cutting blade used on Gruvmaster pipe cutting machines. Based on real steel pipe cutting conditions, the blade was tested through repeated cutting cycles rather than single-cut results. The focus is on wear behavior, cutting stability, usable blade life, and compatibility across multiple machine models under normal working conditions.

This article explains a structural adjustment made to the CM-12 pipe cutting machine to better suit on-site use. While the cutting range, hydraulic system, and working principles remain unchanged, mobility has been improved by adding wheels and a tow handle. The update focuses on easier repositioning during on-site operations without affecting cutting performance.

The CM-20 pipe cutting machine has been updated with a split hydraulic system, replacing the previous integrated design. The hydraulic pump and cylinder are now installed separately and connected by hoses. This configuration is also applied across the 8", 12", and 20" pipe cutting machines, supporting more stable operation in workshop and on-site applications.

The Gruvmaster AG-8Z roll grooving machine has been updated based on real job-site use.

The new version features a larger hydraulic power unit, a telescopic handle for easier movement, and an expanded pipe size range from 1″ to 16″.

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.

Roll grooving machines require different roller materials for different pipe conditions. This article compares plated rollers and stainless steel rollers used on Gruvmaster roll grooving machines, focusing on thin-wall pipe applications, groove quality control, durability, and cost considerations. Selecting the correct roller set based on pipe wall thickness helps improve grooving consistency and overall processing reliability.

Photos from the Gruvmaster factory show roll grooving machines during final assembly. At this stage, machines undergo alignment, fastening, fine adjustment, and inspection. Each unit is assembled by hand following a consistent process to ensure stable structure, smooth operation, and reliable quality before shipment.

The RG-2M by Gruvmaster is a portable combination roll groover designed for 1"–6" pipe sizes. Featuring a compact structure and a new red-black appearance, it is suitable for on-site installation, maintenance, and renovation work. Photos show the current configuration and toolbox layout.

The RG-1X roll groover covers 1"–8" pipe sizes with a compact, integrated structure and stable hydraulic feeding. It suits both workshop and on-site use. Our factory is currently producing a batch of RG-1X units, reflecting strong demand and consistent manufacturing capability.

The new Gruvmaster 219-630 is an upgraded heavy-duty roll grooving machine based on RG-4X, featuring a reinforced frame, larger supports, and enhanced precision.
