The dot punching machine, also known as the continuous marking machine, is used for marking round steel, flat steel, steel pipes, section steel, and other non-ferrous metal materials for tensile test samples.
Technical Requirements
Each shake can produce 41 marking points. The distance between points is 10mm, with an error not exceeding ±0.15mm. The total length is available in 300mm and 400mm marking points*. It is made of ball bearing round steel with a hardness not lower than RC55.
Usage Instructions
Printing at 10mm intervals
When in use, place the sample material into the (sample seat) groove, and adjust the screw nut seat according to the length of the sample material. Adjust the length by turning the screw and adjust the sample seat according to the diameter of the round material. Loosen the fixing screw on the sample seat to move it forward or backward. Align the center of the diameter according to the material requirements, then use your left hand to pull the handle downward until the marking point contacts the sample material, and slightly tighten it. Use your right hand to turn the handle (clockwise) one full rotation to complete.
Printing at 5mm intervals
To print at 5mm intervals, first print at 10mm intervals, then gently push the screw rod handle with your left hand to shift the sample by 5mm. Continue printing once more. After printing, remove the sample.
Precautions
1. Keep the two columns and the punch head well lubricated to ensure smooth and flexible operation.
2. Be careful not to damage the punch head* to avoid losing accuracy and rendering the equipment unusable.
Advantages
Precise construction, easy to use, high efficiency, accurate marking, and easy to inspect and repair.
