Notch Milling Machine

JJNMM Notch Milling Machine

This instrument is an equipment for sample incision processing for the test method of resistance to slow crack growth and slow growth of thermoplastic pipes for fluid transportation. The instrument has a high degree of automation, precise cutting precision, and humanized design, which is convenient for safe use by operators.

1. It adopts industrial PLC automatic control, hoisting a movable and rotating large-size full-color touch screen operation display terminal.

2. Modular design structure, the notch grooving tool is located directly above the test tube, and it is easy to observe and operate when milling the notch.

3. The servo system is used to control the speed and feed rate of the tool to ensure the cutting speed required by the standard.

4. The pipe and the slotting machine should be fixed by mandrel hoisting and clamping, with the tool parallel to the inner wall of the pipe;

It is necessary to ensure that the depth of the milling groove is not limited by the ellipse of the pipe and the difference in wall thickness, and to ensure that the depth of the cut is consistent.

5. X and Y feeds adopt high-precision linear linear guides and high-precision ground ball screws, which have high cutting precision and ensure the validity of the test data for slow crack growth resistance.

6. The high-precision 60o V-shaped carbide cutter ensures that the end surface of the pipe is smooth and clean after cutting.
