Electric Internal Expansion Pipe Beveling Machine

This series of I.D. mounted pipeline beveling machines, including advanced metal beveling machine technology, is characterized by light weight and easy portability. Installation is quick and effortless-the expansion mechanism inserted into the pipe's inner diameter automatically locates the center. In addition to carbon steel, stainless steel, and alloy steel, these metal beveling machines can perform U/V-type weld beveling, chamfering, trimming, and even welded convex flange processing on pipes. This machine adopts an AC 220V high-performance motor for driving, with a motor frequency of 50Hz, current of 6A, and power of 1.2-2KW. It features easy installation, fast operation, and an expansion mechanism that automatically centers itself upon insertion into the pipe. The metal beveling machine is lightweight and highly portable.

This pipeline beveling machine series includes Model 1 and Model 2.

Model 1: Suitable for pipes with wall thickness ≤20mm. The bevel angle can be adjusted by replacing the blade, allowing both internal and external beveling.

Model 2: Designed for thick-walled pipes, processing walls up to 75mm with an adjustable angle range of 0–40 degrees.

Processing Precautions：

1) During cutting operations, intermittently apply cutting fluid to the tool for cooling and lubrication purposes, at a frequency of one application per revolution of the cutter head. A standard water-soluble cutting fluid is recommended.
2) Do not employ a trailing tool holder for machining large-area bevels. Instead, utilise a bevel tool holder for the initial machining of extensive bevel sections, reserving the trailing tool holder for the final, minor beveling operations.
3) Operators must wear safety goggles throughout the entire machining process to prevent cutting fluid from causing eye burns.
4) Metal chips generated during machining should be allowed to fall naturally by retracting the tool, or removed using a specialised chip hook. Direct contact with chips by hand is strictly prohibited.
5) As the cutter head is a rotating component, take care to prevent clothing, hair, or other items from becoming entangled during machining, which could cause injury.
6) Throughout the cutting process, the operator must closely monitor the pipe machining. Should tool breakage or jamming occur, machining must cease immediately. Only after resolving the issue may machining resume.
