Legacy in Automotive
As a global leader in automotive machining solutions for more than 80 years, Kennametal has forged a legacy in the industry based on accuracy, speed and versatility. From Internal Combustion Engine (ICE) production to Electric Vehicles (EV), we machine solutions that drive productivity. We are helping customers grow and evolve in the EV space with custom and standard tools to manufacture components — a direct result of not only our legacy in automotive solutions, but also of our growing and modernized manufacturing footprint in more than 60 countries.
Building Better with Dynamic Partnerships
We are an industry leader when it comes to accuracy, speed and versatility. With over 80 years of experience, we have established relationships with key customers, machine tool builders, suppliers and Original Equipment Manufacturers (OEMs) who partner with us to support the industry's transition from ICE to EV production. Today we are enhancing those partnerships to expand our reach, impact and better serve customers' hybrid and EV needs.
Automotive Expertise Powered from the Core
No one knows automotive machining like Kennametal. We’re extending our proven and longstanding expertise in developing solutions for traditional automotive manufacturing to the unique challenges of EV machining.
Skilled in Aluminum Machining
We equip customers with aluminum-machining solutions designed to deliver high-precision holes, outstanding surface quality and burr-free surfaces. Due to its relatively soft properties, aluminum is typically machined at high spindle speeds, and Kennametal has the tools and experience to support the most effective aluminum machining.
Industry Solutions: Equipped for EV Production
We offer a comprehensive portfolio of innovative solutions that machine tool builders, suppliers and OEMs need to produce EV components.
Aluminum Housings and Covers
Housings and covers in EVs use aluminum alloys. The most complex machining challenges in these components come from thin walls, large diameter requirements and geometric tolerances such as concentricity between the main bore and bearing bore.
Suggested Solutions:
Battery Housings
Battery housings are typically machined from aluminum casting alloys or aluminum extrusion profiles. Aluminum with low silicon content typically produces long chips and is more susceptible to built-up edges on tooling, thin walls and delamination in composite materials.
Suggested Solutions:
Structural Components
Structural components are often made of aluminum extrusion profiles and castings. Machining challenges for these components come from thin walls and fixturing difficulties that cause unstable machining conditions.
Suggested Solutions:
Gears
Gears are made of steel with a combination of hard and soft turning using primarily standard tooling solutions.
Suggested Solutions:
- CBN Inserts
- KCP25C Inserts
- Fix8™
Rotors and Shafts
Rotors and shafts are often machined using primarily standard tooling solutions for various types of steel with high surface hardness and good core toughness such as case-hardened steel, forged steel and heat-treatable steel.
Suggested Solutions:
Carbon Fiber-Reinforced Plastic (CFRP) Components
CFRP components experience surface quality issues including delamination, fiber pull out, uncut fibers and breakout, causing rapid flank wear on turning inserts due to the composite's abrasive nature.
Suggested Solutions:
EV Quick Facts
66 Million Units and Growing
According to S&P 500 Global Mobility, the annual production of electric motors is forecast to exceed 66 million units by 2025.
20% Further with Aluminum
Aluminum is a lightweight material that plays a large role in electric vehicles. According to Cutting Tool Engineering, if a vehicle's weight is reduced by 20% it should be able to travel 20% further on the same charge.
Continuous Innovation Using Additive Manufacturing
Kennametal is utilizing 3D printing design freedoms in select production environments to continually innovate new machining solutions for internal combustion engine vehicles, hybrid and electric vehicles. By leveraging these design freedoms, we are able to improve overall customer go-to-market lead times. By applying both additive and traditional manufacturing processes, Kennametal aims to reduce manufacturing costs, lead times and improve operational efficiencies with machine tool builders, OEMs and tier customers.
Global Application Support
We support local machine tool builders, OEMs and suppliers through a global applications team that can engineer a solution around various complex machines, fixtures and workpiece conditions.
Diverse Manufacturing Footprint
We pride ourselves in providing consistent manufacturing application support and ensuring that reliable information is shared from one region to the next.
