High Precision Pneumatic Pipe Cutting Beveling Machine Cold Cutting
40mm Max Wall
Product Introduction
SFM series are portable processing equipment for cutting, beveling
and end prefabrication of various pipes, with which cutting and
beveling can be conducted at the same time. The SFM Series
manufactured by Bohyar cuts and bevels the pipe end or middle of
pipe by clamping external wall, with processing diameter up to 2100
mm and maximum wall thickness of 100 mm. With an R&D history of
nearly one hundred years, the product can process pipes or casings
accurately, continuously and vertically.
Tool Slides
| Spring tool slide | It is used to track the surface of out-of-round pipes, which can
greatly save installation, adjustment and cutting time. It can
quickly and automatically track the system to ensure even feed, and
can keep standard wall thickness of large diameter counterbore when
combined with counterbore tool slide. |
Thick-wall tool slide | It can be applied to SFM 0206 to 4248 with stroke of 64 mm; It can be used in large-size pipes and pipes with different wall
thicknesses. |
| Drilling and milling tool slide | Achieve pipe cutting by using the drilling and milling. High-strength tool slide, smooth cutting and simple operation. |
| Internal boring tool slide | It is suitable for pipeline internal boring. |
| Bridge type tool slide | It is suitable for pipeline internal boring and single point
beveling. |
