TGK20 series CNC deep hole scraping and rolling machine

Boring rolling machine is also called boring rolling machine, scraping rolling machine, oil cylinder scraping rolling machine, etc. It adopts European advanced boring and rolling compound processing technology, and can complete the boring rolling function with one reciprocation. The machining accuracy can reach IT8 level, and the surface roughness can reach Ra005-0.2μm. It is mainly used for finishing the inner hole of hydraulic cylinder. Compared with the traditional honing machine, this equipment has the advantages of low noise and no pollution, and can greatly save labor cost and high processing efficiency. Compared with the old boring + rolling or boring + honing, the machining time can be saved by 80-90%. Equipment model: 3 meters, 6 meters, 9 meters, 12 meters (processing length)--Boao scraping and rolling machine

Machining capability: Rough boring, semi-fine boring, fine boring and rolling can be completed at one time for the inner hole of the cylinder. The production efficiency is greatly improved, which is more than 10 times that of the traditional honing method. Achieving the mirror effect of the inner wall of the cylinder (Ra=0.03um~0.2um)--Boao Scraping and Rolling Machine

Squeegee roller polishing machine, deep hole scraper, the efficiency is 5-8 times higher than ordinary deep hole and quilting grinding. It is a processing equipment specialized in the manufacture of hydraulic cylinders, which is a reform in deep hole technology and another technical breakthrough in technology. It is the work that can only be completed by 2-3 times of normal deep hole, and it is finished in one time. He integrates rough boring and fine boring into one, and uses push boring to complete rough and fine boring at one time, and uses the timing of tool retraction to complete the rolling procedure after boring. Rolling processing makes the workpiece roughness up to Ra0.4. Can replace ordinary deep hole and quilting. Deep hole machining rolling technology is a kind of non-cutting process, which can make the internal control surface reach the surface roughness required by the workpiece through property deformation. Several advantages of rolling:

1. Improve the surface roughness, the roughness can basically reach Ra≤0.08µm.

2. Correct the roundness, the ovality can be ≤0.01mm. Coaxiality≤0.06mm/M,

3. Improve surface hardness, eliminate stress and deformation, and increase hardness by HV≥4°

4. There is a residual stress layer after processing, which improves the fatigue strength by 30%. --Boao Scraping and Rolling Machine

By rolling and rotating the rolling tool on the workpiece surface, unevenness is flattened while excess material is squeezed into the gap. As a result, plastic deformation can occur. The smoothing effect is achieved by the flow of material layers around the entire surface, and the processing speed is determined by the processing material and the required surface specifications.
Features and Benefits:

1) Surface quality reaches Rz<1μm

2) Very high dimensional stability with tolerance class IT8

3) Safe, fast and low-cost machining of the assembly surface

4) Use only one process

5) The surface is harder and more wear-resistant after rolling

6) Non-cutting processing, low noise

7) Simple tool, no extra cost

8) Almost no cooling is required, and can be used with various cooling systems

9) Adapts very quickly and can be produced safely

10) Very high load-bearing ratio (up to 90 %)

11) Very economical compared to grinding, honing or lapping.

12) Can be placed on various conventional and CNC machine tools.

13) Case hardening between 5 % - 10 %.

14) Short processing time.

15) Long service life. It can improve the life of sliding parts, and the sealing materials such as O-rings and gaskets of hydraulic and pneumatic cylinders are resin and metal. The sealing material needs to rub against the cylinder body, so the sealing material should have good compliance with the metal, and it should not be worn due to friction while maintaining sealing. A raised portion is formed by the profile curve after grinding and shot peening, and this raised portion will significantly wear the sealing material. The rolling process is to roll the convex part to form a smooth plane, and the contact with the sealing material is smooth, which obviously reduces the rod-like sliding and wear, so it is widely used in automobile brake cylinders, hydraulic cylinders, valve bodies and Buffer and other manufacturing fields. --Boao Scraping and Rolling Machine
