It adopts high precision ball screw drive and linear guide track for suppor. 1) Main technical parametersGap: V2 type (GB/T 229-2007), U2, U3, U5 type (GB/T 229-2007) (2mm type is with machine, 3, 5mm type is alternative)Journey of broaching: 350mmBroaching speed: 2.3m/minSpecimen size: 10×10,7.5,2.5×55mmDimensions: 570×430×1240mmWay of driving: ball screw driveWeight: 180KgWorking motor: 380V 50Hz 0.4Kw2) Advantages1.It adopts high precision ball screw drive and linear guide track for support. This structure ensures stability of the broach and geometric precision of gap.2.It makes use of the principle of one-time-molding. It can assure gap 100 percent qualified.3.The broach is made of imported W18Cr4V material. Its hardness is high and its wear-resistance is excellent. Each broaching knife can process up to 20,000 specimens.4.It is equipped with double-pole and processes two specimen gaps simultaneously with a “V” type and a “U” type (also two “V” or two “U” type). Whether processing “V” or “U” notch, the pole do not need changing. Processing specimen gap only needs 10 seconds.
