A horizontal lathe designed specifically for turning large-diameter pipe fittings

Pipe thread lathe, also known as pipe thread lathe, is a horizontal lathe designed specifically for turning large-diameter pipe fittings. It is characterized by a relatively large spindle through-hole diameter (generally above 135mm) and chucks at the front and rear of the spindle box for easy clamping and processing of large-diameter pipe fittings or rods. This product is widely used in mechanical processing operations in industries such as machinery manufacturing, petroleum, chemical, coal, geological exploration, and urban water supply and drainage.

Pipe thread lathes are mainly divided into two types based on their control and operation methods: ordinary pipe thread lathes and CNC pipe thread lathes.

Pipe thread lathes generally have a large through-hole on the spindle box, and the workpiece passes through the through-hole and is clamped by two chucks located at both ends of the spindle for rotary motion. There are generally two ways to feed the cutting tool: one is to drive the slide plate and tool holder located in front of the bed by the screw, which is the same as that of a regular lathe; Another method is to use a flat comb blade external thread cutting head (see automatic opening and closing thread cutting head) located on the slide plate in the center of the bed to cut into the workpiece and move forward accordingly. Some machine tools for processing long pipes also come with workpiece support devices, such as center frames, follower frames, rear supports, etc.
