In automated equipment, precision instruments, and industrial transmission systems, precision knurled bushings serve as crucial connection and transmission components. The uniformity of their surface texture, the precision of their inner bore, and the tightness of their fit with the shaft directly determine the operational stability and service life of the equipment. Dongguan Ganyuan Hardware Technology Co., Ltd., relying on its advanced CNC machining system and strict quality management standards, focuses on the customized production of high-precision stainless steel knurled bushings, providing reliable, durable, and precise metal connection solutions for various high-end manufacturing fields.
I. Core Product Advantages: Anti-slip and Wear-resistant, Precision Fit
Ganyuan Hardware's knurled bushings are made of high-quality stainless steel, processed by CNC precision turning and knurling, possessing the following significant advantages:
Anti-slip and Wear-resistant: The uniform and dense knurled texture effectively increases friction, preventing relative slippage between the shaft and the bushing, ensuring the stability and reliability of power transmission;
Precision Fit: The inner hole machining accuracy can reach ±0.01mm, with extremely small clearance between the bushing and the shaft, resulting in no looseness or abnormal noise after assembly, ensuring smooth equipment operation;
Reliable Strength: Made of high-strength stainless steel, strengthened by heat treatment, it can withstand high torque and high frequency operating conditions, suitable for heavy-duty or high-speed operation scenarios;
Wide Applications: Outer diameter, inner diameter, length, and surface treatment can be customized according to customer needs to meet the assembly requirements of various equipment such as SMD taping machines, COF packaging machines, carrier tape pulling systems, and textile machinery.
II. Manufacturing Process: From Blanking to Inspection, Precision Manufacturing Guaranteed Throughout the Entire Process
Ganyuan Hardware strictly adheres to a five-step closed-loop process: Blanking → Turning → Knurling → Polishing → Inspection, ensuring that every knurled bushing meets industrial-grade precision standards:
Blanking: High-quality stainless steel bars are selected and precisely cut according to the drawings, ensuring uniform blank allowance to lay the foundation for subsequent processing;
Turning: Rough and finish machining of the outer diameter, inner hole, and end face is completed on a CNC lathe, ensuring that dimensional and geometric tolerances meet design requirements;
Knurling: Using specialized knurling tools, extrusion knurling is performed on a lathe, ensuring uniform texture, consistent depth, and no burrs or cracks;
Polishing: Fine polishing is performed on both inner and outer surfaces to improve surface smoothness, reduce frictional resistance, and enhance corrosion resistance;
Inspection: Each product undergoes dimensional measurement, hardness testing, visual inspection, and actual installation verification to ensure stable performance and no abnormal wear.
III. Technical Support: A Multi-Type CNC Equipment System for Intelligent Production
Ganyuan Hardware is equipped with a variety of advanced CNC machining equipment, forming an intelligent production system covering the entire process of turning, milling, drilling, and grinding:
CNC Lathes: High-efficiency single-axis turning, suitable for simple rotating parts, such as bolt shanks and heads;
Five-Axis CNC Machining Centers: High-precision five-axis linkage machining, capable of completing complex curved surfaces and multi-angle cutting;
Mill-Turn Turning Centers: Multi-functional turning and milling machine, flexible four-axis machining, suitable for parts with multiple holes and faces;
Four-Axis CNC Machining Machines: Four-axis linkage, suitable for efficient machining of moderately complex parts.
IV. Packaging and Transportation Solution: Multi-layer Protection, Safe Arrival
To ensure the knurled bushings are not damaged during transportation, Ganyuan Hardware adopts a packaging and transportation solution of "multi-layer protection + stable boxing + precision parts protection + end-to-end transportation":
Multi-layer protection: The product is wrapped with shockproof foam, moisture-proof bags, and other materials to effectively resist vibration and moisture during transportation;
Stable boxing: The product is secured in a customized cardboard box to prevent displacement or collision during transportation;
Precision parts protection: Special protection is given to key parts such as the surface and inner hole of the knurled bushing to prevent scratches or deformation;
End-to-end transportation: Reliable logistics partners are selected to ensure the product is delivered safely and on time to the customer.
