XYOON is a professional manufacturer and supplier of cutting ring pre-assembly machines in China, offering flexible procurement options including in-stock availability, bulk supply, and custom tooling solutions. Designed specifically for the pre-assembly (bite-in) of single and double cutting rings, the equipment accommodates seamless carbon steel and stainless steel tubing with outer diameters ranging from 3mm to 42mm. It features controlled, uniform pre-assembly force to ensure consistent sealing standards, meeting the high-volume production needs of fitting manufacturers and OEMs. Units can be purchased individually or integrated with tube cutting and deburring equipment to form a complete processing line.
1. Manual pre-assembly relies on operator feel to control tightening force; insufficient force leads to inadequate bite-in, making the system prone to oil leaks under high-pressure vibration, while excessive force can tear the tube wall, rendering the material scrap.
2. The cutting ring pre-assembly machine utilizes a motor to deliver constant thrust, ensuring uniform deformation of the cutting ring and consistent bite-in depth across every tube, thereby significantly increasing the pass rate for sealing quality.
3. Post-assembly, the bite-in pattern is uniform and precise; when paired with our F37 flanges or double cutting ring fittings, the assembly remains leak-free even under long-term high-pressure conditions.
1. It covers industry-standard seamless steel tubes with outer diameters of 3mm–42mm, reliably processing both thin-walled and standard-walled stainless steel and carbon steel tubing.
2. It is compatible with both single and double cutting ring fittings (the two mainstream sealing types) and supports fittings compliant with DIN and ISO international standards, eliminating the need for equipment changes for export orders.
3. Tube diameters can be switched simply by changing the limit tooling; a single operator can complete the changeover in two minutes, making it ideal for workshops handling mixed-specification production.
1. The machine features a thickened, integrated frame that minimizes vibration during continuous operation, preventing dimensional drift and making it suitable for high-volume workshops running two-shift schedules.
2. Equipped with a visual stroke scale, the machine allows operators to clearly monitor the cutting ring's advancement distance, enabling even novices to get up to speed quickly and reducing training costs.
3. The protective housing is equipped with an anti-pinch sensor that automatically halts the machine if an anomaly occurs during feeding, thereby reducing the risk of workplace accidents.
1. Clear away iron filings and dust from the feed inlet daily to prevent debris from abrading the internal feed spindle, which could compromise pre-assembly precision.
2. Apply specialized grease to the sliding guide rails every 200 hours of operation to prevent sticking or binding during the pushing and pulling of the tooling.
3. If the equipment is to remain idle for more than two weeks, wipe down the tooling, apply anti-rust oil, and store it in a dry, well-ventilated warehouse to prevent metal components from rusting.
