- Cast iron workpieces start rusting within several days after machining, driving surging rework costs.
- Fine iron powder remains suspended during grinding, triggering secondary scratches on workpieces and limiting yield improvement.
- Cutting fluids erode machine tool paint and trigger corrosion, leaving equipment prematurely aged.
- Inconsistent silane treatment undermines coating adhesion, leading to paint peeling shortly after application.
If you manufacture automotive axles, drive shafts, drive axles or hub bearings, these challenges are far from isolated cases – they represent widespread pain points across the entire industry.
Why These Issues Deserve Greater Attention Now
As core components of vehicle chassis and transmission systems, automotive axles maintain steady demand alongside the growth of automobile manufacturing. Two emerging trends have made production stability more critical than ever.
First, electric drive axles (E-Axles) are seeing rapidly rising demand. Compared with traditional axles, E-Axles impose stricter standards for gear machining, bearing lubrication and surface protection, which directly affect transmission efficiency and long-term component reliability.
Second, lightweighting drives material upgrades. New materials require metalworking fluids with enhanced stability and stronger surface protection performance. Conventional lubrication and maintenance systems can no longer keep pace.
Meanwhile, key components including axle housings and differential housings are still mainly produced from cast iron and steel, generating sustained demand for machining protection and anti-corrosion coatings. Manufacturers that secure consistent performance across the full workflow – machining, equipment maintenance, surface treatment and coating – will gain clear advantages in product yield and on-time delivery.
One Integrated Solution Covering the Full Axle Production Workflow
Many manufacturers source machining fluids, gear oils and surface treatment chemicals from separate suppliers. Fragmented supply creates inconsistent technical standards, and suppliers often shift blame once production defects occur.
AMER connects all core production processes and delivers a unified integrated solution chain:
Machining Fluids → Equipment Lubricants → Surface Treatment Chemicals → Coatings
Targeted products address typical bottlenecks at every production stage, detailed as below.
01 Machining Fluids: Solve Three Long-Standing Challenges in Cast Iron Machining
During cast iron and carbon steel cutting and grinding, manufacturers commonly face three problems: rust formation on workpieces and machine tools, secondary scratches caused by poor iron powder sedimentation, and cutting fluid-induced paint corrosion on machinery.
Solution: Amer SF311 Fully Synthetic Machining Fluid for Cast Iron
This rust-resistant, water-soluble synthetic cutting fluid fits rough and precision machining of cast iron and carbon steel, compatible with CNC machines and grinders.
- Long-lasting rust protection: Delivers indoor rust prevention for over 7 days at 2% concentration, and up to 30 days at 10% concentration.
- Superior sedimentation performance: Iron powder settles completely within 10 seconds; slideway oil separates rapidly within 20 seconds, lifting grinding yield by up to 30%.
- Excellent paint compatibility: Passes GB6144-2010 paint compatibility test without dissolving or corroding machine coatings.
02 Equipment Lubricants: Extend Service Life of Gears and Bearings
Drive axles, manual transmission gears and hub bearings require lubricants featuring strong anti-wear capacity, high-temperature resistance and water tolerance.
Option 1: Amer GL-5 85W/140 Heavy-Duty Gear Oil

Option 2: Amer LG2 & LG3 Heavy-Duty Grease for Automotive Hub Bearings
Complex lithium soap grease designed for high-temperature, low-speed and heavy-load bearings and gears.
- High-viscosity base oil with tackifiers prevents grease throw-off under high-speed operation.
- Robust extreme pressure anti-wear performance reduces abrasion and avoids metal sintering.
- Good water drainage capability, maintaining stable performance even contaminated by rainwater.
03 Surface Treatment: The Invisible Foundation for Qualified Coatings
Coating quality heavily depends on high-quality pre-treatment before painting.
Option 1: Amer Baolimei 7890A + 7890B Phosphate-Free Degreaser
A mild alkaline cleaner developed for steel, cast iron and non-ferrous metal cleaning, specially optimized for silane pre-treatment processes.
