Mass-application scenarios for standard adjustable reamers
2025-11-14 14:58
Project Background
In automotive transmission manufacturing, Low-grade tapered hub D18H7 Precision holes are critical functional components that not only demand dimensional stability but also require extremely high surface roughness. Although solid carbide reamers have long been commonly used in such applications, with the continuous rise in tungsten prices, issues such as persistently high tool costs, relatively short tool life, and difficulties in compensation have become increasingly prominent.
The customer’s original process uses Solid carbide reamer (coated, internal coolant) , the processing parameters are: S300 / F90 Three major pain points have been exposed in actual mass production:
-
Low efficiency Insufficient feed rate, slow machining cycle.
-
Roughness instability: Ra often hovers around 0.8, with significant fluctuations.
-
Short lifespan: The average lifespan of solid carbide reamers is only about 80 pieces, leading to frequent replacements and persistently high costs.
To improve production efficiency while reducing tool costs, the customer chose to evaluate Ruiding’s Xueji® E adjustable reamer.
Ruiding Solution
Ruiding Xueji®E Adjustable Reamer ：
-
The blade body exhibits strong fatigue resistance and long-term stability, making it ideal for batch processing.
-
High-speed cutting capability, with stable surface roughness achievable up to Ra0.4 or lower
-
The diameter structure is finely adjustable, and wear compensation is simple and straightforward.
-
Optimized cutting-edge geometry design for lighter, smoother, and more stable machining.
-
Can be re-sharpened and reused multiple times, significantly reducing overall costs.
-
Built-in high-pressure cooling channels, Significantly extend lifespan by 30%+
Based on the operating conditions, Ruiding recommends the following tool parameters: S2400 / F1400 Achieve the optimal balance between efficiency and roughness.
On-machine effect verification (real test data)
✨ Outstanding first-piece performance
Aperture: D18.015
Roughness: Ra 0.2
Roughness is more than four times better than the original process.
✨ Batch Stability
In actual mass production, the surface roughness has been consistently maintained below Ra0.3 over the long term, and its high consistency significantly outperforms that of solid carbide reamers.
✨ Lifespan
The Snowy Weather series adjustable reamers have an average service life of over 1,000 pieces per tool—more than 12 times that of solid carbide reamers.
Cost reduction, efficiency improvement (significant benefits)
-
Efficiency improved by approximately 15 times (from F90 to F1400)
-
Improved yield rate: Roughness is more stable.
-
Tool costs have dropped significantly: Adjustable structure + repeatedly repairable
Against the industry backdrop of rising tungsten prices, increasing costs for solid carbide blades, and extended lead times, the welded adjustable hinge cutter solution is becoming the preferred choice for an increasing number of customers in the precision parts sector.
