In modern pipeline engineering, the roll grooving machine has gradually replaced traditional welding and threaded connection methods as an efficient pipe pre-processing tool. By processing standard grooves at the end of pipes, it provides a precise foundation for the rapid installation of grooved pipe fittings, and is widely used in fire protection, HVAC, water supply, and petrochemical industries.
The working principle of the roll grooving machine utilizes an electric motor to drive the concave pressure wheel to rotate, while the hydraulic system drives the convex pressure wheel to apply pressure to the rotating pipe, thereby extruding the required groove in the pipe wall. This method not only processes quickly, completing a groove in seconds, but also achieves precision up to 0.1 mm, effectively ensuring the sealing of pipe connections and avoiding leakage risks. Compared with traditional processes, using a roll grooving machine can reduce long-term costs by about 40% and shorten installation time by 30%.
Grooving Machine Operation Manual
I. Main Applications and Technical Specifications
Applicable pipes: Seamless steel pipes, galvanized pipes, plastic-lined pipes, etc.
Working principle: The rotating concave pressing wheel (lower wheel) drives the pipe to rotate, and the convex pressing wheel (upper wheel) gradually applies pressure to the pipe under the action of the hydraulic cylinder, forming a groove.
Common parameter reference:
Voltage: Usually three-phase 380V.
Processing range: Common models cover specifications such as DN50-DN300 (2"-12").
Spindle speed: Usually low-speed rotation (about 23 rpm).
II. Pre-operation Preparation
Site and power supply:
Place the machine on a flat and level ground. For large-diameter machines, it is recommended to fix it with anchor bolts.
Check if the power supply is 380V, ensure there is no phase loss, and the motor rotation direction is correct (usually clockwise when viewed from the handle side, or observe whether the pipe rotation direction is close to the positioning plate).
Machine inspection:
Check if the reducer is short of oil and whether the hydraulic oil tank level is normal.
Check if the rollers (pressing wheel and knurling wheel) are installed correctly, and whether the specifications match the steel pipe to be processed.
Workpiece treatment:
Pipe cutting: The pipe end cut must be perpendicular to the pipe axis.
Deburring: Remove burrs, rust, and dirt from the inside and outside of the pipe end.
Weld seam treatment: For welded steel pipes, the internal weld seam at the pipe end must be ground flat, with a grinding length of no less than 60mm.
III. Standard Operation Steps
Pipe support:
Place a triangular support at the rear of the machine according to the pipe length.
Put one end of the steel pipe into the lower roller and support of the grooving machine, and the other end on the support.
Leveling: Adjust the support height to make the steel pipe in a horizontal state, or make the support end slightly higher (about 1 degree) to prevent the pipe from deviating outward during grooving.
Press the pipe end against the machine's positioning plate (baffle).
Depth adjustment (key step):
Start the machine and let the lower roller drive the steel pipe to rotate.
Press down the hydraulic handle to make the upper pressing wheel contact the pipe surface.
Set the limit:
Refer to the "grooving depth parameter table" on the machine nameplate.
Adjust the limit nut. The usual method is: first let the upper wheel contact the steel pipe, rotate the limit nut until it contacts the top surface of the cylinder, and then reverse rotate the nut by the corresponding scale according to the required depth (e.g., 2.0mm).
Note: The gap between the limit nut and the top surface of the cylinder is the grooving depth.
Grooving operation:
After confirming everything is ready, keep the machine running.
Slowly press down the hydraulic handle, and the upper pressing wheel starts to apply pressure to the steel pipe.
Observation: When the limit nut contacts the top surface of the cylinder (or reaches the set depth), do not stop the machine immediately.
Shaping: Let the steel pipe continue to rotate for 1-2 revolutions to ensure the groove is round.
Unloading and measurement:
Turn off the power and stop the machine.
Turn the pressure relief valve counterclockwise to raise and reset the upper pressing wheel.
Take out the steel pipe, and use a groove gauge (caliper) to measure the groove depth and width, confirming whether they meet the standard (e.g., GB5135.11).
IV. Problem Analysis and Solutions
Problem No.

3
Abnormal sharp noise during grooving
1. Improper pipe support position2. Pipe end not perpendicular3. Excessive friction
1. Adjust pipe support position left or right to optimal point2. Recut pipe end vertically using special tool3. Apply thin layer of lubricant on pipe end
4
Pipe cannot advance or shakes left and right during grooving
1. Equipment or pipe not level2. Stabilizing wheel not engaged3. Pipe end damaged
1. Use level to calibrate, adjust support to keep pipe and equipment level2. Slightly offset pipe by 1°-2°, then re-tighten stabilizing wheel3. Cut off damaged pipe end or smooth it
V. Safety and Maintenance Precautions
Safety first:
Operators must wear protective equipment. It is strictly forbidden to operate rotating parts with gloves (to prevent entanglement), and long hair must be tied up.
When the machine is running, it is strictly forbidden to put hands into the roller area.
Before any adjustment or roller replacement, the power supply must be cut off.
Daily maintenance:
Lubrication: Grease the pressing wheel shaft and spindle daily; regularly check reducer lubricating oil.
Cleaning: Clean iron filings and debris on the knurling wheel surface with a wire brush daily to prevent slipping.
Inspection: Regularly check if U-frame bolts are loose and if circuits are aging.

Introduction to Threading Machines
Threading machines are specialized electric tools used to cut external threads on the ends of metal pipes (such as water and gas pipes, galvanized pipes) so they can be connected. Their core function is to manufacture standard-sized pipe threads, making them indispensable equipment in pipe installation and maintenance projects.
2. Main Types Introduction
1. Light-Duty (Manual/Portable) Threading Machine
Description: Simple structure, small size, and lightweight. Usually requires manual feed, where threads are cut by rotating a handle. Some models are motorized but still require manual control during thread cutting.
Pros:
Low cost, portable, suitable for confined spaces or high-altitude work.
Cons:
Low efficiency, labor-intensive, relatively poor precision and consistency of threaded products, requires higher operator skill.
Application Scenarios:
DIY at home, simple repair work, scattered construction sites with small workload, budget-limited situations.
2. Heavy-Duty (Electric/Automatic) Threading Machine
Description: The most common industrial-grade threading machine. Motor-driven, it automatically completes a series of actions such as clamping the pipe, cutting threads, and automatic chamfering through internal gear mechanisms. Operators only need to place the pipe, select the die, and start the machine.
Pros:
Extremely efficient, high-quality and precise thread processing with strong consistency. Greatly reduces labor intensity and is easy to operate. Usually integrates pipe cutting and chamfering functions.
Cons:
Bulky, expensive, requires power supply, relatively inconvenient to move.
Application Scenarios:
Pipe prefabrication factories, large construction sites, plumbing engineering companies, municipal projects, and other occasions requiring large quantities of efficient pipe thread processing.
3. Hydraulic Threading Machine
Description: Utilizes a hydraulic system to provide powerful clamping force and stable feeding force, offering more robust power. Typically designed as ultra-heavy duty.
Pros:
Tremendous power, capable of processing large-diameter (e.g., DN100 and above) and thick-walled pipes, runs smoothly, extremely durable.
Cons:
Largest in size and weight, highest price, relatively complex maintenance, requires knowledge of hydraulic systems.
Application Scenarios:
Petroleum, chemical industry, shipbuilding, large pressure pipelines, and other industrial fields requiring the processing of large, high-strength pipes.
4. CNC Threading Machine
Description: The highest degree of automation in threading equipment. Parameters are set via a CNC system to automatically complete the entire process including loading, fixed-length cutting, clamping, threading, and unloading.
Pros:
Extremely high degree of automation and intelligence, highest machining accuracy, capable of achieving unmanned continuous production, efficiency is unparalleled.
Cons:
Extremely expensive, programming and debugging require professionals, suitable for fixed large-batch production modes.
Application Scenarios:
Large pipe manufacturing plants, standard parts factories, automotive manufacturing, and other modern production lines requiring ultra-large scale, ultra-high precision, and consistency.
3. Summary of Core Pros and Cons (Based on Common Heavy-Duty Electric Threading Machines)
Pros:
Efficient and Labor-Saving: Efficiency increases by dozens of times compared to manual threading, significantly reducing worker labor intensity.
Reliable Quality: Processed threads have standard dimensions, high precision, and good surface finish, ensuring pipe connection sealability.
Integrated Functions: Most models are 'three-in-one' (threading, pipe cutting, internal chamfering), reducing tool change time.
Easy Operation: Can be mastered with simple training, reducing dependence on senior technicians.
Cons:
High Initial Investment: A quality heavy-duty threading machine is quite expensive.
Inconvenient Mobility: Heavy equipment requires transportation tools and a power source on site.
Maintenance Requirements: Regular maintenance is needed (such as oiling, cleaning, replacing dies/cutting blades).
Power Dependency: Limited use in field environments without electricity (requires a generator).

Comprehensive After-Sales Service System — Top Priority!
Service Network: Understand the distribution of the supplier's after-sales service points nationwide or in your region. A comprehensive network means quick support when equipment issues arise.
Parts Supply: Ensure that consumable parts (like dies and cutting heads) and core components are readily available and reasonably priced. Difficulty in obtaining parts is a primary cause of equipment downtime.
Warranty Policy & Technical Support: Clear warranty periods, responsive customer service, and technical guidance can greatly reduce your worries after purchase.
III. Practical Purchasing Guide: Clarify Needs, Match Precisely
Before contacting suppliers, please clarify your own situation:
Application Scenario: Is it for threading large-diameter pipes on a construction site, processing small batches of round steel in a workshop, or for home/property maintenance? This determines whether you need a portable, bench top, or heavy-duty industrial machine.
Processing Volume & Frequency: For high-intensity, continuous operation, you must choose industrial-grade durable products. For intermittent, low-frequency use, you might consider more cost-effective economic models.
Budget & Cost-Effectiveness: Set a reasonable budget. Remember, cost-effectiveness considers the entire lifecycle cost, including purchase cost, consumable costs, repair costs, and losses due to downtime. A slightly more expensive but stable and reliable device is far better than a cheap one that frequently malfunctions.
Summary Suggestion:
Choosing a threading machine supplier is a comprehensive consideration process. We recommend prioritizing manufacturers with a good reputation in the industry, a professional and rich product line, robust core technology and processes, and the ability to provide fast, professional, and localized after-sales support.
You can make a wise final decision by visiting industry exhibitions, consulting experienced peers, and requesting detailed technical information and quotes from multiple ideal suppliers for comparison. You might even ask for a trial or to visit existing user cases. A reliable threading machine is a crucial guarantee of your productivity and is worth your effort in careful selection.
