Product Description

Our Advantages

Advantages of LJA hydraulic thread rolling machine

It is primarily used for rolling various precision external threads and high-strength standard parts, including standard threads, trapezoidal threads, and modular threads. Suitable materials for rolling include various carbon steels, alloy steels, and non-ferrous metals with elongation greater than 10% and tensile strength less than 100 kgf/mm². Thread rolling machines are primarily used for rolling workpieces of various specifications, including building wall threads, top threads, trapezoidal threads, and combination threads. They offer the advantages of simple operation and high efficiency.The cold continuous rolling process is an advanced non-cutting process that effectively improves the internal and surface quality of workpieces. The radial compressive stress generated during processing significantly increases the fatigue strength and torsional resistance of the workpiece. It is an ideal process with high efficiency, energy saving, and low consumption

1. The main shaft features a combination of double-row needle roller bearings and cylindrical roller bearings, ensuring precise and rigid spindle operation.
2. The transmission system utilizes a multi-stage spindle gearbox for smooth transmission and easy shifting.
3. The hydraulic system utilizes modular valves, resulting in a compact footprint, attractive appearance, stable performance, and easy operation and maintenance.
4. The machine control system allows for easy selection between manual, semi-automatic, and automatic modes for adjusting operating times. A new digital dial allows for direct control of the roller system's time and pause times.

Product Description

Machine Introduction

This machine utilizes both electric and hydraulic drive, digital control, and advanced construction (welded with 45# carbon steel). It boasts superior performance and high efficiency, placing it at the forefront of the industry both domestically and internationally. Its affordable price, high quality, rational structure, simple operation, and reliable quality make it an ideal machine for producing both non-standard threads and standard parts (bolts).
