Enhanced worm gear efficiency in industrial bottle washer application with Berusynth EP 1000
July 18, 2026Optimizing machining performance in ‘5-Axis CNC machines’ with cutting fluid, BECHEM Avantin 361
Machining in modern 5-axis CNC machines require cutting fluids that deliver superior cooling, lubrication, chip evacuation, and long-term stability. While conventional cutting fluids are ill-equipped for operations, it has been observed that several cutting fluids marketed from reputed brands also struggle with issues like foaming, microbial contamination, shorter sump life, residue build-up and poor surface finish, leading to higher maintenance costs and reduced productivity.
Below case study demonstrates how BECHEM’s specialised cutting fluid, BECHEM Avantin 361 helped optimize machining performance and improve operational efficiency in 5-axis CNC machines consistently.
Customer: One of India's leading manufacturers of precision-engineered powertrain components, catering to renowned domestic and global OEMs across the EV, automotive, off-highway, defence, agriculture and railway industries.
Machining Parameters:
Components: Cylinder heads and cylinder blocks
Material: Automotive grade Aluminium alloy

Customer was using a semi- synthetic cutting fluid from a reputed brand ‘X’.
Issues encountered by the CNC machine operators:
- Reduced tool life due to poor chip evacuation at the cutting zone .
- Excessive foaming led to coolant overflow and spillage, affecting workplace safety.
- Microbial growth in the coolant tank caused unpleasant odour and skin irritation.
- Poor machine cleanliness due to residue build-up, impacted shop floor hygiene.
A 30-day trial was conducted on a CNC machine by filling its 750-litre tank with the water-based cutting fluid, BECHEM Avantin 361.
Trial observations:
- Extended tool life: Superior lubricity of BECHEM Avantin 361 reduced friction at the cutting zone, resulting in longer tool life.
- Elimination of odour issues: Unpleasant odour generation and skin irritation issues were completely resolved, significantly improving the working environment for operators.
- Enhanced machine cleanliness: Effective flushing minimized residue accumulation and deposits, resulting in cleaner machines and improved shop-floor conditions.
Trial result:
Following the substantial improvement in sump life, machine cleanliness and overall machining performance, the customer implemented BECHEM Avantin 361 as the only coolant to be sourced for aluminium alloy machining operations across the shop floor covering 30 CNC machines
Long-Term Benefits:
Extended coolant sump life: With BECHEM Avantin 361, the coolant sump life increased from approximately 12 months to 30 months, significantly reducing coolant replacement frequency and maintenance costs.
Why BECHEM Avantin 361 metal cutting fluid?
- Longer Tool Life: Excellent lubricity of BECHEM Avantin 361 minimizes friction between the cutting tool and workpiece, reducing wear and extending tool life.
- Efficient Cooling and Chip Evacuation: As a water-soluble cutting fluid, BECHEM Avantin 361 maintains effective cooling and chip evacuation, improving machining efficiency.
- Ensures cleaner machines and workplace: Advanced formulation of BECHEM Avantin 361, inhibits coolant degradation, unpleasant odours and the frequency of coolant replacement, lowering maintenance costs.
- Reliable Performance in High-Pressure Coolant systems: Low foaming tendency of BECHEM Avantin 361 ensures stable coolant delivery even at high pressures.
- Compatibility with metals: BECHEM Avantin 361 is suitable for the machining of automotive aluminium alloys, steel, cast iron and stainless steel.
