The process of screw broaching is usually divided into two steps

Spiral broaching machine is a kind of machine tool used for metal material processing with high efficiency and precision, which is widely used in manufacturing industry. It performs machining by rotating and pulling, and is capable of realizing the machining and production of various spiral parts.

Spiral broaching machines are mainly composed of a spindle, a feed system, a tool holder and a bed. Among them, the spindle is responsible for rotating the parts, while the feed system is used to control the speed and direction of movement of the cutting tools. The tool holder is equipped with cutting tools that can be used to perform cutting operations on different shapes as required. The bed is the supporting part of the whole machine tool to ensure the stability and accuracy of the machine.

The machining process of a screw broaching machine is usually divided into two steps: first, by rotating the workpiece so that its rotary axis is at a certain angle with the feed axis; then, by using the feed system, the cutting tool is gradually pushed in the direction of the rotary axis in order to complete the cutting operation on the workpiece. During the machining process, the workpiece will produce a spiral cutting trajectory with the movement of the cutting tool to form the desired spiral part.

Its advantage lies in its efficient and precise machining capability. Firstly, the machining efficiency can be greatly improved because the relative motion of the cutting tool and the workpiece is carried out along the spiral trajectory. Secondly, the machine can realize the machining of various complex shapes of spiral parts, including threads, spiral grooves, etc., with strong adaptability. In addition, it can also realize high-precision machining, and its machining accuracy can reach the sub-millimeter level, which meets the manufacturing requirements of many precision parts.

The screw broaching machine has a wide range of applications in many fields. In the automobile industry, it is used for processing engine crankshafts, gears and other key components; in the aerospace field, it is used for processing complex parts inside the aircraft engine; in the electronic equipment manufacturing industry, it is used for processing precision connectors, electronic devices and so on. It can be said that the screw broaching machine has become one of the indispensable tools in the modern manufacturing industry.
