Thread cutting machine

The thread engraving machine (also known as the thread steel engraving machine) is suitable for tapping the internal threads of various steel parts. It can process coarse pitch, fine pitch, and non-standard pitch threads, and can perform forward and reverse operations. It is widely used in the surface strengthening, connection pretreatment or decorative treatment of thread steel for construction. Through the rolling forming technology, the processed threads have the characteristics of high precision, high strength and good surface finish.

Threaded steel bar surface texture processing (construction steel bar connection processing)
Cold-rolled ribbed steel bar preparation
Bridge, tunnel, rail transit steel bar head thread processing
Thread engraving machine is widely used in machinery manufacturing, automobile manufacturing, aerospace, petrochemical and other industries, and is an indispensable equipment in thread processing.

High forming efficiency Multi-groove mold design can form multiple threads at one time, improving processing efficiency.
High thread accuracy The thread angle after processing is accurate and the tooth shape is clear, which is easy to connect.
Strong adaptability The equipment is stable and durable The spindle is strong in rigidity, the thread rolling wheel is wear-resistant, and it is suitable for continuous production.
Easy operation Supports CNC or PLC control system, with high degree of automation and convenient operation.

The thread engraving machine is a processing equipment used to engrave the thread structure (especially the thread steel grain) on the surface of steel bars or metal bars. The main structure includes
The main shaft and thread rolling wheel system are equipped with multiple sets of thread rolling wheels (thread dies), which are rolled and formed by rotating and contacting the workpiece.
The thread rolling wheel is designed according to the specifications of the steel bar, with standard grain, deformation grain, etc.
The clamping system positions and clamps the workpiece through hydraulic or mechanical devices to ensure stable processing.
The feed mechanism moves the workpiece or tool along the axial direction to cooperate with the rolling process. It is mostly driven by servo motors or hydraulic systems.
The cooling and lubrication system is equipped with a coolant circulation system to prevent the thread rolling wheel from overheating and extend its service life.
The machine tool bed and control system are made of cast iron or steel welded structure, which is stable and durable. It is equipped with PLC or digital display control to support automated operations.
