FAQs:Camshafts for Automotive Industry Applications

Camshafts are an engine's constituent parts that regulate the timing of opening and closing of the intake and exhaust valves of gasoline, diesel and hybrid engines. Camshafts are produced in single and twin-cam configurations, expert in valve lifts between 8-15mm, timing accuracy of plus or minus 0.5 degrees and mileage durability ranging between 200,000 to 500,000 miles.

Fire steel 4140, boasts exceptional strength and hardenability to 58-62 HRC for resistance to any form of wear. Chilled lobe cast iron is economically durable for mass production of engines. For maximum performance, supreme billet steel is the ideal for motor racing and high yield engines.

The camshaft lobe profile achieves an accuracy of plus or minus 0.02 mm, for bearing journals, plus or minus 0.012 mm, while 0.005mm, is the covariance in the center of the timing drive. For the surface microns, 0.4 Ra per microns. These are the estimations of the smoothness of the bearing to ensure valve opening and closing to the proper timing, and prolong the usefulness of the bearing.

Yes. The IATF 16949, automotive component standards, SAE engine parts, and ISO 9001 standards, engine durability, automotive industry standards, quality guidelines and management system are all automotive industry standards. All certifications and documentation on timing accuracy are available.

Standard camshafts require 15-22 days including machining, heat treatment, and grinding. Custom performance cams need 6-8 weeks. Prototype camshafts can be completed in 10-16 days.

Generally, how much lead time do you need in order to feel comfortable taking on camshaft manufacturing jobs? For standard camshaft jobs, we need 15 to 22 days to complete the entire process of machining, heat treating, and grinding the camshaft. For custom performance camshaft jobs, we need 6 to 8 weeks. However, prototype camshaft jobs only take 10 to 16 days to complete.

Of course. We develop camshafts for specific needs and functionality including performance racing cams for max power with aggressive lift and duration profiles; torque optimized truck and diesel camshafts for heavy-duty applications; VVT assemblies with integrated actuators and sensors; lightweight overhead cam designs for DOHC; boost-targeted camshafts for turbo/supercharged engines; and other more specific features such as integrated reluctor wheels, hollow construction to reduce weight, multi-piece assemblies for flexibility in construction, and custom grind profiles to achieve determined performance characteristics.

The machine's ability to produce cam lobe profiles within a ±0.02 mm tolerance makes certain that valve timing and lift have a controlled breathing efficiency and power output that is within a margin of ±2-3% of design specifications. The increased precision of bearing journal dimensions controlled to a ±0.012 mm tolerance afford greater oil clearance, thereby eliminating premature wear and ensuring 200,000+ mile durability. A controlled surface of less than 0.4 Ra microns reduces friction and, therefore, parasitic power losses (1-2 hp improvement and increased fuel economy). The material that is most advantageous is forged steel that, due to its strength and hardenability, costs less than cast iron, an economical choice for durability in production engines. Quality manufacturing impacts relative camshaft performance. Reliable automotive engine operation, supporting passenger cars with smooth idle and fuel economy, and performance vehicles with max power output >100 HP/liter, diesel trucks with >500,000 mile durability and peak torque delivered, and racing engines with valve timing controlled at 8,000+ RPM through 200,000-500,000 mile service life for precise timing control, performance and reliability. Optimized heat treatment yields uniform cam lobe wear resistant hardened material. Controlled surface finish decreases friction heat wear during operation. Specific design parameters Complement engineered machining capabilities to exceed performance requirements.
