Description
◆ Core Technologies
- Uses quick positioning blocks for fast centering and positioning, followed by clamping.
- Hydraulic clamping ensures cutting accuracy of ±0.1 mm; hydraulic drive provides strong power; rational structure and high reliability.
- Through the internal tool holder and tool, internal chamfering and internal pipe-end machining can meet welding requirements for thick-walled pipes.
- Optimized design of chamfering head, guide bush, pipe-end machining, and end-face chamfering; reasonable equipment structure; stable hydraulic system; easy operation and maintenance.
- Uses an internal centering and clamping mechanism with accurate positioning, strong clamping force, and high safety and reliability.
◆ High Efficiency
High chamfering efficiency; each chamfering operation takes less than 3 minutes.
◆ Power System & Quality
- Hydraulic drive with powerful force; internal oil circuit; high safety; large-diameter feed cylinder with precise and smooth feed.
- Uses internationally renowned first-line brands; Parker hydraulic components; reliable performance.
- Adjustable chamfering angle to meet the needs of different chamfer angles.
- The machine base adopts a belt-type structure for easy movement and placement.
◆ Wide Adaptability & Versatility
- Adjustable tool holders and supports adapt to different pipe diameters, wall thicknesses, and chamfer forms; easy adjustment when changing pipe diameters, wall thicknesses, or chamfer types.
- The machine offers strong cutting power and good performance with different pipe materials; capable of meeting internal chamfering requirements for various pipe diameters and wall thicknesses.
Features:
- Multiple chamfering forms available: V-type, double V-type, U-type, etc.
- Internal chamfering function; maximum chamfer length up to 120 mm.
- Unique structural design, suitable for chamfering heat-exchanger tubes with diameters up to 500 mm.
