Model No.: PR-FR4-3
In plastic field, many suppliers know the material, but they know little about the machining. Some other suppliers know about the machining, but they don't know the material properties. In the two situations, problems happen frequently.
If you have same problem, come to PRIOR PLASTIC, we solve the problem for you perfectly. Experienced both in material and machining, customers are very glad to cooperate with us.
The machining process include below
1.Turning: For parts which have high surface requirement, wide-head cutters are better. When processing thin walled and soft material, cutters like knife are recommended.
2. Milling: When milling the surface, end-milling is more cost-effective than circular milling. For circular and forming cutter, it should have less than two cutter edges. In this case, the tolerance caused due to the edge vibration can be lowered to the minimum.
3. Sawing: Thin saws are usually used to saw thick parts to avoid the heating caused by friction. It would be better to use sharp and big sawblade.
4. Drilling: When drilling the solid materials, make sure to use sharp drill, otherwise the increasing pressure during drilling will cause material cracks.
