This series of Crankshaft Connecting Rod Neck CNC Lathe, a type of Horizontal Lathe, is meticulously engineered for the exclusive task of turning crankpins. It stands out as a High precision Lathe and High efficiency Lathe, perfectly suitable for the precision machining of crankpins in diverse applications. Whether it's for motorcycles, automobiles, diesel engine sets, heavy trucks, or large marine crankshafts, this lathe excels. By replacing traditional rough processes with high - speed and ultra - precise turning, it significantly enhances productivity. It also functions as a Multi - functional Lathe, adaptable to various production requirements, making it an ideal choice for OEM/ODM Lathe projects in the Metal Turning Lathe industry.
1. Crankshaft Machining & Remanufacturing
Used for turning, grinding, and polishing crankshaft connecting rod journals to restore worn-out or damaged engine components.
2. Automotive & Diesel Engine Production
Essential in manufacturing high-performance engines for cars, trucks, and heavy-duty vehicles.
3. Marine & Aerospace Crankshafts
Machines crankshafts for ship engines and aircraft power systems, where durability and precision are critical.
4. Industrial Machinery & Power Generation
Used in producing crankshafts for generators, compressors, and pumps.
5. Custom & High-Precision Engineering
Ideal for racing engines, high-speed motors, and custom crankshafts requiring ultra-fine finishing.
