Third, the surface roughness does not meet the requirements of the main reasons 1) lathe rigidity is not enough, such as the loose plug of the carriage, the transmission is unbalanced and cause vibration. Of course, the installation of the lathe is not stable will also cause vibration, the surface of the workpiece is rough due to vibration Degree is reduced. Previous page
1. All steel fabric parts and the size of prefab house can be made according to clients' requirement: cheapest prefab house| prefab house. Small Prefab Homes,Prefab Homes,Prefab Houses,Prefab Modular Homes Jinan Zhengtang Insulation Decoration Material Co.Ltd , https://www.ztwallsiding.com
2) If the rigidity of the turning tool is insufficient to cause vibration, use a rough shank as much as possible to reduce the length of the turning tool; if the rigidity of the workpiece is insufficient, it will cause vibration. Therefore, when turning the slender shaft, apply the center frame, or use a clip. Instead of two top clips.
3) Incorrect geometric parameters of the cutting part of the turning tool According to the machinable characteristics of the workpiece material, a reasonable and suitable cutting angle is selected to reduce the surface roughness.
4) Due to the formation of built-up edge, the surface roughness of the workpiece is reduced. The built-up edge is very strong. Due to the participation of the built-up edge, the surface of the workpiece may be pulled or scratched. It should be avoided during turning. produce. Combined with the above reasons, it is necessary to know early prevention in the process, eliminate the problem in the bud, improve the accuracy of the workpiece, and meet the design requirements. 
2. The prefab house is low cost, durable structure, convenient relocation , and environment-protection.
3. The material of prefab house is light and easily to installation. one 50 square meter house five workers 1-3days finished installation, save manpower and time.
4. All the materials of prefab house can cycle-use, Meeting the require of environment protection in the world. Special is in the large-scale house projects in the developed region.
5. We used the high quality galvanized sheet and foam as the materials of the wall and roof .So the prefab house is good for fire proofing, water proofing, etc.
