Slow wire cutting is already high-precision processing, but many customers will encounter the problem of rough surface of the inner hole, and it is difficult to meet high-end requirements even if it is trimmed many times. Many people wonder why the inner hole can meet the basic assembly, so why improve the finish? Hsihwa fluid polishing can easily solve this pain point. Let's explain the key in simple words.

Improving the finish of the inner hole is by no means superfluous, but the key to ensuring that the product is easy to use and durable. After the slow wire is cut and repaired, fine knife marks and burrs will remain on the surface of the inner hole. These small defects will affect the performance of the part: for example, in hydraulic and precision transmission scenarios, rough surfaces will increase friction, reduce sealing, and even cause damage to components; in high-end fields, substandard finish will also affect assembly accuracy and fail industry inspections. And after the finish is improved, parts wear is reduced, their lifespan is longer, and later maintenance costs can be reduced.

In response to this situation, Hsihwa's solution for fluid polishing is simple and efficient. Instead of traditional rigid polishing tools, it uses a fluid with high-precision abrasive grains as a "grinding tool", which is driven by high pressure to allow the fluid to flow in the hole at high speed and initialize repeatedly. These abrasives are like countless small brushes, evenly grinding the inner wall of the inner hole, which can remove knife marks and burrs without damaging the size of the inner hole, and easily achieve no dead angle fine polishing.

Hsihwa Polishing will customize an exclusive polishing plan according to the size, material and initial roughness of the inner hole, polish it step by step, precisely control the pressure, and ensure compliance through professional inspection. Polishing with Hsihwa fluid can easily solve the problem of rough inner holes with slow wire cutting and repair, and upgrade the quality of parts.
