What hardness can the YS8 turning tool machine?
3 Answers
YS8 alloy turning tool YT15 (P10) has a hardness of ≥91, suitable for semi-finishing and finishing of continuous cutting of carbon steel and alloy steel. Here are some precautions regarding automobile driving: Cold Engine Warm-up: Proper warm-up helps form an "oil film" between engine components, thereby reducing engine wear. Timely Gear Shifting: When driving a manual transmission vehicle during the break-in period, shift gears promptly and appropriately to avoid incorrect behaviors such as high gear with low RPM or low gear with high RPM. Also, avoid using a single gear for an extended period. Regular Maintenance: Simply follow the manufacturer's recommendations in the vehicle manual. After reaching a certain mileage or time period, promptly inspect and maintain the vehicle, including changing the engine oil and oil filter, and conduct a comprehensive check of the chassis system. Avoid Emergency Braking: Emergency braking not only impacts the braking system during the break-in period but also increases the impact load on the vehicle's chassis and engine.
I've worked in the repair shop for over a decade and frequently use YS8 turning tools to machine hard components. It can handle materials with considerable hardness, like camshafts in car engines or transmission gears - those steel parts with surface hardness around HRC 50-65 pose no problem. If the material is too soft, it actually accelerates tool tip wear; if it exceeds HRC 65 hardness, the tool will chip. Through daily repair work, I've learned that proper cutting fluid and appropriate speed are essential for efficient and safe operation. Remember to always inspect tool condition before starting work - don't lose big by trying to save small. With automotive parts becoming increasingly precise, selecting the right tools is crucial for reducing repair time.
I've done quite a few car DIY projects at home, and the YS8 lathe tool is one of my regular tools. It can turn materials with hardness between HRC 45-60, such as when I used it to machine the edges of brake discs or suspension components. I've tried it on higher hardness alloys, and it struggles a bit more. When operating, it's important to control the feed rate—too fast and it can overheat and damage the workpiece. In car modifications, knowing the limits of your tools can prevent unexpected issues. I always clean the tool head after each use to extend its lifespan. Overall, it offers great value for money when working with medium-hard materials and is well-suited for amateur hands-on work.
