Steel Tube Double-ended Automatic Hole Milling Machine
Article Source： Updated：2015-12-11
1.Main purpose and scope of application
This machine is processing belt conveyor roller tube automation of the special equipment at both ends. Use of domestic and foreign production of various types of cast iron or stamping bearing roller, the pipe seam allowance, are all available processing on this device .
The machine adopts mechanical fast clamping device, clamping reliable; Clamping force is simple and convenient adjustment. Cutter feeding by hydraulic pressure drive, can be stepless speed regulation.meanwhile, left and right two feed oil cylinder adopt hydraulic synchronous circuit, can feed at the same time, the blade at the same time. Radial feed the manual, can adjust the knives accurately according to processing requirements; And equipped with hydraulic automatic knife when cutting tool feed to the desired location （dead point） automatically when a knife, avoid scratch has been processed on surface. Electric control part adopts imported Japan programmable controller （PLC） as core of control system.
This machine reliability, simple operation and convenient maintenance, is wide applicable range, high efficiency, especially suitable for large quantities of roller processing.
2. Application conditions
This machine can be used within no more than 1000 meters, the environment temperature + 10 ~ 40 ℃， no dust and all kinds of corrosive medium. Processed tubes to remove floating rust.
