Extension of tool life by 14% through upgradation of gear hobbing oil with product SL 0010NC
- SL 0010NC
- Improvement in surface finish & tool life
- Commercial Vehicle Component Manufacturing
- Neat Cutting Oil
The Challenge
A leading commercial vehicle component manufacturer has been using Castrol Ilocut 1945 for gear hobbing applications. The manufacturer sought to enhance the existing tool life and surface finishing. Metallurgy SAE 4140 is machined using Carbide Hobb in Suraksha CNC, where the average cost of the cutter is Rs. 53,000 to deliver a robust surface. However, the tool was required to change after machining 1500 components. Furthermore, the manufacturer achieved an rA value of 0.8 up to 400 components, after which it kept increasing up to 1500 components only. After that, the tool was changed
The Solution
- When Product SL 0010NC was introduced, there was an immediate improvement in surface finish & tool life observed.
- There were also sporadic scoop mark issues reported on machined components that were eliminated by upgrading to Product SL 0010NC.
The Business Benefit
- Castrol’s Product SL 0010NC has a unique ‘Extreme Pressure Additive Package’ that has delivered a consistent surface finish value of rA=0.8 up to 800 components & the tool life was extended up to 1700 components.
- Tool life improved by 14%
- The surface finish of rA=0.8 is consistently achieved to 800 components
- Tool cost decreased by Rs.4.15/component
- Total Monthly Savings = No.of components produced in this machine per month(25000) x Rs.4.15/- = Rs. 1,03,750/month
- The manufacturer achieved an annual savings of Rs. 12.45 lacs
