thermal break CNC knurling machine Function: 1.The special equipment processing of thermal barrier aluminum profile. 2.It’s used to knurl on the notch of thermal barrier profile through rotating knife at a high speed. 3.Aluminum profile must be knurled in order to improve the horizontal shearing force of extrusion profile. Working Principle: Adjust knurling knife into the notch, draw the profile by rotating the knurling knife, and make teeth on the inner cavity of the aluminum profile. Features: Stepless speed regulation is available with a frequency converter. Advanced two axis CNC systems realizes storing data for various aluminum profiles. Convenient operating interface. Technical parameters Voltage : 380V/50Hz Total power: 1.5Kw Knife diameter: 80mm Feeding speed: 0-90m/min Max processing size of profile: 250mm*180mm (W*H) Distance between teeth makers: 6mm/180mm (Min/ Max) Overall dimension: 1300mm*1000mm*1650mm (L*W*H) Weight: 800Kg Guarantee 1.Engineers available to service machinery overseas 2, Warranty: one year for whole machine, two years for main components and whole life service 3, Free to train operator and maintainer (the travel expense is not included) 4, Free to provide the latest development technology
