Suzhou Hanxin Precision Components obtained the patent for a grinding device for casing joint processing, so that the casing joint can be better polished
What was authorized is a new patent, which provides a new technical solution for the grinding of casing joints. In order to improve the processing efficiency of pipe joints, Suzhou Hanxin Precision Components has obtained a patent for a grinding device for casing joint processing, so that the casing joints can be better polished. It also provides a new technical solution for improving the processing quality of pipe joints.
Technological innovation solves fixed problems
The traditional grinding device is often not flexible enough when fixing casing joints of different sizes, requiring frequent fixture changes, which greatly reduces production efficiency. The core of the new patent lies in its adaptive fixed component, which uses the linkage between the push rod, hinge plate and limit block to automatically adjust the clamping range.
This design enables one piece of equipment to handle multiple specifications of joints, reducing equipment investment and replacement time. For processing companies, precision parts processing means that when faced with diversified orders, the production line can respond faster, reduce downtime losses caused by changing fixtures, and directly improve the flexibility of production.
Structural design improves grinding accuracy
This device is composed of a base, an adjusting motor, a grinding wheel mechanism, a rotating feeding mechanism and many other parts. The position of the grinding wheel can be accurately adjusted by the motor and push rod to ensure that it maintains the best contact angle and pressure with the workpiece. At the same time, the workpiece itself is driven by the rotating motor to rotate.

This method of making the grinding wheel move together with the workpiece can achieve uniform and comprehensive grinding, avoiding local over-grinding or under-grinding that may occur in manual grinding. Precise motion control is the key to ensuring the flatness of the end face of the casing joint and the quality of the sealing surface, which has a direct impact on the sealing reliability of the pipeline connection.
Automated integration reduces manual dependence
Based on what is stated in the patent, this device integrates the loading push rod and fixed components for precision parts processing , which reflects its potential for automated operation. For the operator, it may only be necessary to place the blank, and the subsequent clamping operations, positioning operations, grinding operations, and unloading operations can all be completed by the device according to established procedures.
Against the backdrop of rising labor costs and improved process standards, the value of this type of semi-automatic or fully-automatic equipment has begun to stand out significantly. It has functions that can reduce dependence on skilled craftsmen, maintain stable processing quality, and reduce human errors caused by fatigue. It is particularly suitable for manufacturing scenarios that require high-volume and consistent processing.
Corporate background highlights R&D strength
A company in Suzhou submitted this patent. The company was established in 2020 with a registered capital of 5 million yuan and focuses on the manufacturing of special equipment. Public information shows that this company has multiple patents and administrative licenses for precision parts processing , and has participated in bidding projects.
A company that has only been established for a few years can continue to obtain technology patents, which shows that it attaches great importance to R&D investment and technology accumulation. In the Yangtze River Delta region, where high-end manufacturing is concentrated, such innovation is a key support for companies to gain a foothold and develop in an extremely competitive environment. It also reflects the vitality of China's start-up companies in the field of special equipment.
Potential applications and market value

Casing joints are widely used in pipeline connections in the petrochemical industry, urban water supply and gas supply, and construction projects. The quality of its interface polishing is directly related to the connection strength and leakage prevention performance. If this patented technology can be successfully commercialized, it will serve these important industrial fields.
What is helpful to improve the manufacturing level of engineering components of the entire piping system is efficient and precise grinding equipment. For equipment manufacturers, if a specific process pain point is solved, it is possible to open up a market segment, thereby gaining a competitive advantage, and thus promoting the development of processing technology in related industries.
Future Outlook and Industry Impact
This patent is classified as a utility model, focusing on practical improvements in structure and function, and its commercialization path is relatively short. The company is very likely to carry out prototype manufacturing and process testing next, and explore verification on the production lines of cooperative customers.
If the feedback from the market shows a positive trend, there is a possibility that such a design concept may be applied to many other similar rotary parts for trimming and polishing or processing and manufacturing equipment, thereby triggering a series of improvement innovations and changes. Uninterrupted subtle innovations at the technical level are precisely the key and important force that can make "Made in China" stride forward in the direction of high quality and high efficiency.
