Notch Making Machine

Desciption
NSTM401C notch making
machine is to pressnotch on metallic specimen used for WTT test. it is
hydraulic driven with electronichs control . the cylinder movement is
controlled by electromagnetic valve. equipped with limit switch it will stop
automatically when notch depth reaches preset value. press tool is built with
W18Cr4V tooling alloy material , with wear-resistence and long use life this
machine can also be used to flatten line pipe steel specimen it is easy to operate
with high stabillity and efficiency .
