Thermal break knurling machine Function: It is used to put knurling wheels on the notch of thermal barrier aluminum profile to improve the horizontal shearing force of the profile. Working principle: Adjust knurling wheels into the notch, draw the profile by rotating the knurling wheels, and make teeth on the inner cavity of the profile. Features: 1.One machine can realize three functions ——knurling, inserting, and film sticking. 2.Two knurling heads. each head is driven by a motor and powered on linear guiding for horizontal adjustment by hands separately. 3.Both heads could be adjusted horizontally and vertically by electric. 4.Stepless speed regulation is available with a frequency converter.
