The Demands Of Gearbox Machining
Gearbox manufacturing requires absolute precision, flawless surface integrity, and strict thermal control. As automotive and electric vehicle (EV) technologies evolve, transmission systems face stricter demands for efficiency and noise reduction. Modern machining processes like turning, milling, and grinding generate extreme heat and friction. Without advanced metalworking fluids, manufacturers risk dimensional errors, shortened tool life, and costly downtime.
Powering Quality With Gtl Technology
oelheld developed SintoGrind, a high-performance, GTL-based grinding oil, complementing the widely recognised and proven DiaGrind 535/15. SintoGrind delivers exceptional performance in gear grinding applications, enabling superior surface quality, enhanced process efficiency and consistent high-quality output. Formulated with Gas-to-Liquid (GTL) technology, it features rapid air release properties that ensure a stable oil flow directly at the grinding zone. This enables faster cycle times, eliminates grinding burns, and delivers superior surface finishes. The advanced formulation provides maximum lubricity under extreme pressure, drastically reducing friction during high-speed operations.
Cutting Costs And Extending Tool Life
oelheld fluids build a stable lubricating film that lowers cutting temperatures and extends tool longevity. By reducing wheel loading and glazing, SintoGrind minimizes the wear and consumption of grinding wheels. These factors lower the overall cost of ownership while supporting higher Overall Equipment Effectiveness (OEE) across multi-shift, automated production lines.
Tramp oil accumulation over time can compromise grinding performance. oelheld delivers consistent performance, process stability and reliability throughout the entire oil service life.
Enhancing Factory Safety And Cleanliness
Beyond pure performance, GTL-based SintoGrind improves the plant environment. A high flash point reduces fire risks in high-energy grinding zones, ensuring safer operations. Furthermore, its excellent cleaning action prevents sludge formation and filter blockages.
By keeping machines, workpieces, and filtration systems clean, it lowers maintenance costs and protects operations against unplanned downtime.
