Automotive

At ZY Superhard Tools, we specialize in providing high-precision PCD (Polycrystalline Diamond) cutting tools and high-performance CBN (Cubic Boron Nitride) grinding wheels tailored to the automotive industry. Alongside these core offerings, our expert team also has a strong track record of delivering customized PCBN cutting tools and other non-standard superhard solutions, engineered to meet unique manufacturing challenges.

PCD Tools Applications

Our PCD tools are designed for a wide range of automotive components, ensuring precision and efficiency in every project. Key workpieces include:

• Cylinder Heads (e.g., milling deck faces, valve seats)
• Engine Blocks (aluminum; milling, boring)
• Pistons (grooving, turning)
• Steering Gears & Knuckles (aluminum)
• Gearbox Housings & Oil Pans (aluminum)
• Brake Calipers (aluminum)
• Throttle Valves & Scroll Plates
• EV Components (e.g., aluminum battery trays, motor housings)

Compared to traditional carbide tooling, utilizing PCD tools for machining non-ferrous metals and composites often leads to significantly extended tool life, faster cycle times, and superior surface finishes.

Example: Throttle Valve Processing

To showcase the precision and performance of our tools, here are recommended parameters for throttle valve machining:

• Formed Milling Cutter: 3500 RPM, feed rate of 0.045 mm/tooth
• Radial Cutter: 4000 RPM, feed rate of 0.055 mm/tooth
• Stepped Reamer: 4200 RPM, feed rate of 0.015 mm/tooth
• Adjustable Fine Boring Cutter: 5500 RPM, feed rate of 0.05 mm/tooth

These specifications highlight the efficiency and accuracy our tools bring to your production process.

Illustrative Application: Aluminum Engine Block Milling

A common challenge in high-volume engine block production is maximizing throughput while maintaining surface quality on deck faces. Switching from carbide face mills to ZY PCD face mills often yields dramatic improvements. In typical scenarios, customers experience:

Ability to run at significantly higher cutting speeds and feeds, shortening cycle times.

Tool life increases of 10x or more, drastically reducing downtime for tool changes.

Improved surface finish and flatness, ensuring better gasket sealing.

CBN Grinding Wheels

Our CBN (Cubic Boron Nitride) series grinding wheels are engineered for precision grinding of critical engine components, delivering exceptional surface finish and dimensional accuracy. Common applications include:

• Camshafts (precision lobe grinding)
• Crankshafts (journal, pin, and fillet grinding)
• Transmission Shafts & Gears (finish grinding after heat treatment)
• CV Joints & Ball Screws (precision groove grinding)
• Valves & Valve Train Components
• Fuel Injection Components

Compared to conventional abrasive wheels, our CBN wheels can dramatically reduce grinding times, improve component dimensional accuracy and consistency, and offer significantly longer wheel life.

Grinding Wheel Specifications

We offer grinding wheels tailored to your machine, whether for vertical or horizontal grinding of camshafts and crankshafts. Popular specifications include:

• 1A1
• 9A1
• 9A1B
• 14A1
• 3A1
• 3Q1
• 14LL1

Example Application: Crankshaft Journal Grinding

Our CBN wheels deliver exceptional performance in high-precision tasks like crankshaft journal grinding:

• Wheel Used: A high-performance ZY Vitrified Bond CBN Grinding Wheel (e.g., Shape 1A1 specification)
• Typical Grinding Parameters (for Steel Crankshaft):
  • Wheel Speed (Vs): Optimized within the 80-120 m/s range
  • Workpiece Speed (Vw): Typically 60-90 m/min
  • Infeed Rate: Fine-tuned based on stock removal needs and finish requirements
• Achieved Results (Typical):
  • Efficient stock removal while consistently maintaining tight geometric tolerances (roundness, cylindricity).
  • Excellent surface finish (often Ra < 0.2 µm), potentially reducing subsequent polishing steps.
  • Extended dressing intervals and overall wheel life, improving machine uptime compared to conventional abrasives.
  • Minimized risk of thermal damage to the critical workpiece surface.

Illustrative Application: Camshaft Lobe Grinding

Achieving the precise profile and surface finish on camshaft lobes is critical for engine performance and emissions. Conventional wheels can struggle with rapid wear and maintaining consistency. Implementing ZY’s vitrified CBN grinding wheels typically allows manufacturers to:

• Maintain sub-micron surface finishes consistently across long production runs.
• Significantly extend the period between wheel dressing, boosting productivity.
• Achieve higher stock removal rates safely, reducing overall cycle time per camshaft.
• Benefit from a stable, predictable grinding process ensuring part quality.
