The bevelling machine is special designed for processing the end sharp of H-beam, such as milling the flange, beveling groove, and milling arc. Its performance and efficiency mainly depend on the stability during the milling process, the rigidity and stability of lathe bed, work piece, clapping and tool system. Our bevelling machine has left and right clamping columns which has enough strength to clamp the H-beam on its web direction. Two pressure heads are fixed on both slide plates which presses the two flange of H-beam on the left and right clamping columns. Therefore, the cutting force is closed in the machine and tool system to ensure the good reliability of milling. Accordingly, the working efficiency is improved.
The CNC steel bevelling machine SUK series have high performance price ratio and is convenient to operate. Comparing with the similar products at home and aboard, it has the following advantages:
1. For adopting the programming and frequency modulation components, each unit can work independently. The most suitable speed is set for each cutter for prolonging the life-time of cutter. Therefore, the machine is more economic.
2. Adopting mechanical feed device, the feed speed of work piece can be adjusted automatically, ensuring the reliability and safety of feed.
3. With the automatic positioning device, there is no need for manual adjustment for positioning of work piece. The milling for ends grooves of flange and arched gaps of web plate can be completed in one time, greatly improving the production efficiency.
4. The blade for milling arc and groove can be turned; The size of groove can be adjusted according to requirement. The processing surface is high in quality.
5. This machine is well designed with the high rigidity of lathe bed and column. For the closed clamping system, there is little noise and vibration in processing.
6. Controlled by PLC, the programming can be completed on the touch-screen.
