CJANM-II Electric Type Sample Notch Making Machine for the non-metal material impact toughness testing Functions: Notch making Machineis used for the notched specimen preparation equipment used in the impact toughness test of non-metallic materials by the cantilever and simple beam impact testing machine. It can clamp 20 specimens at a time and process more than 100 notches every 10 minutes. The notched size is accurate, the efficiency is high and the operation strength is greatly reduced. The instrument has high automation, high efficiency of sample preparation, complete protective devices, convenient installation and use, beautiful appearance and humanized design concept. Parameters : 1) table travel: > 90mm 2) feed speed: 30mm / min 3) sampling efficiency: more than 100 / 10min 4) feed rate: 0-2.5mm optional 5) feed stroke: 10 mm 6) type of notch made: customized according to tool specification 7) external dimension: length 450mm × width 390mm × height 360mm 8) power supply voltage: 220V, single-phase three wire system Product configuration: 1) one host 2) one sample centering gauge block 3) a type a tool Alloy steel import tool:
The imported alloy steel cutting tools are made of special alloy materials in Europe, which are specially used forelectric notched prototype, machining the standard sample notches for impact test of cantilever beam and simply supported beam. The hardness is higher than HRC60, the surface roughness is lower than Ra0.4, and the edge angle is 30 ± 0.1 °. It can be grinded repeatedly and has a long service life. Type A cutter: the notch size of the sample is < 45 ° ± 0.2 ° ± r = 0.25 ± 0.05 Type B cutter: the notch size of the sample is < 45 ° ± 0.2 ° ± r = 1.0 ± 0.05 Type C cutter: the notch size of the sample is < 45 ° ± 0.2 ° ± r = 0.1 ± 0.02 Note: the user can choose one of the above tool types according to the actual demand
