Product Features


Specialized Threading Mechanism

These lathes are equipped with a specialized threading mechanism that can process various types of threads, such as metric threads, inch threads, and tapered threads. The threading accuracy is high, ensuring a tight fit between pipes.


Adjustable Chuck

The chuck of the QK1313 and QK1319 can be adjusted according to the diameter of the pipe, ensuring firm clamping of the workpiece. This reduces the vibration during machining and improves the threading quality.


Automatic Feeding System

The automatic feeding system of the lathe can realize continuous threading operations, reducing manual intervention and improving production efficiency. The feeding speed can be adjusted according to the processing requirements.


Product Operate Guide



Preparation Before Processing

1. Familiarize with the Drawings: Clearly identify various parameters of the pipe thread, such as thread diameter, pitch, length, and precision requirements.


2. Select the Cutting Tool: According to the specifications and processing requirements of the pipe thread, select appropriate thread processing cutting tools, such as taps, dies, or thread milling cutters, etc. Then, correctly install the cutting tool on the tool holder of the machine tool.


3. Install the Fixture: Choose a suitable fixture to clamp the pipe to be processed. Ensure that the pipe is firmly installed and its axis coincides with the axis of the machine tool spindle to guarantee the processing precision.


4. Machine Tool Warm-up: Start the CNC pipe thread machine tool and let all components of the machine tool warm up. Generally, the warm-up time is 15 - 30 minutes to stabilize the precision and performance of the machine tool.


5. Return to Reference Point: Operate the machine tool to perform the return-to-reference-point operation to establish the machine tool coordinate system, providing a reference for subsequent processing operations.


Program Preparation and Input



1. Program Preparation: According to the parameters of the pipe thread and the processing technology requirements, use the programming language of the CNC system to prepare the processing program. The program should include the movement trajectory of the cutting tool, cutting parameters (such as cutting speed, feed rate, cutting depth, etc.), and auxiliary functions (such as spindle start/stop, coolant switch, etc.).


2. Program Input: Input the prepared processing program into the CNC system through the operation panel of the machine tool or external input devices (such as USB flash drives, data cables, etc.). Then, check and debug the program to ensure its correctness.


Tool Setting Operation




1. Manual Operation: Use the manual operation function of the machine tool to move the cutting tool close to the position of the pipe.


2. Determine the Zero Point: Generally, select the end face or outer circular surface of the pipe as the zero point. Through the contact between the cutting tool and the pipe, set the corresponding zero point position in the CNC system to determine the relative position relationship between the cutting tool and the workpiece.


Processing Process Control




1. Start the Spindle and Feed Movement: According to the program settings, start the spindle rotation and simultaneously start the feed movement of the cutting tool to begin the processing of the pipe thread. During the processing, pay attention to observing the cutting state of the cutting tool, the surface quality of the pipe, and the running sound of the machine tool, etc. If there is any abnormality, stop the machine immediately for inspection.


2. Monitor the Cutting Parameters: Closely monitor the changes in cutting parameters such as cutting speed, feed rate, and cutting depth to ensure that they meet the processing technology requirements. If the parameters are found to be unreasonable, adjust the program or relevant settings of the machine tool in a timely manner.


3. Measurement and Adjustment: During the processing, stop the machine as needed and use measuring tools (such as calipers, thread gauges, etc.) to measure the processed pipe thread. Check whether its dimensions and precision meet the requirements. If there is any deviation, analyze the cause and adjust the program or processing parameters.


After Processing


1. Stop the Movement: Press the relevant buttons to first stop the feed movement of the cutting tool, and then stop the spindle rotation to make all components of the machine tool stop moving.


2. Remove the Workpiece and Cutting Tool: Carefully remove the processed pipe and cutting tool to avoid damaging the processed surface and the cutting tool.


3. Clean the Machine Tool: Promptly clean the chips and debris on the workbench, tool holder, guide rail, and other parts of the machine tool, and perform necessary lubrication and maintenance on the machine tool.


4. Turn off the Power: Finally, turn off the power of the CNC pipe thread machine tool and make a good record of the equipment usage.
