Industrial Parts Washing and Degreasing Systems
Machined components are almost always contaminated with cutting oils, machining coolant, swarf and metal fines after manufacturing.
Before parts can be assembled, coated, heat treated or shipped, these contaminants must be removed.
Industrial parts washing machines and degreasing systems are designed specifically to clean machined components efficiently and consistently.
Modern Rotajet industrial parts washing machines are widely used across engineering and manufacturing industries to remove oils and machining contamination from metal components.

Why Machined Parts Must Be Cleaned

During machining operations, components are exposed to a range of contaminants including:
- cutting oils
- machining coolant
- metal swarf
- grinding dust
- polishing compounds
- corrosion protection oils
If these contaminants remain on parts they can cause several manufacturing problems.
Assembly Issues
Oil and debris can interfere with tight tolerances and precision assemblies.
Coating Failure
Paint, plating and coatings will often fail if surfaces are contaminated with oil.
Heat Treatment Problems
Residual coolant or oil may burn during heat treatment.
Quality Control Failures
Clean surfaces are often required for inspection and measurement.
For these reasons, industrial degreasing machines are a critical part of modern manufacturing processes.
Rotajet designs industrial parts washing machines specifically for removing machining oils and contamination from components.

Industrial Parts Washing Machines for Machined Components
Industrial parts washers are designed to remove oil, coolant and contamination from metal components.
These machines automate the cleaning process and ensure consistent results.
Typical machines include:
- spray parts washers
- aqueous degreasing machines
- multi-stage parts washing systems
- automated component cleaning machines
Rotajet spray washing machines use high-pressure spray jets, heated cleaning solutions and filtration systems to remove machining contamination efficiently.

The Industrial Degreasing Process
Modern parts washing systems use a multi-stage cleaning process to remove contamination.
Rotajet industrial parts washing machines automate this process to ensure consistent cleaning results.
Stage 1: High Pressure Washing
High-pressure spray nozzles remove oil, coolant and debris from component surfaces.
Mechanical force breaks down heavy contamination.
Stage 2: Heated Detergent Cleaning
Heated cleaning solutions dissolve oils and machining fluids.
Industrial detergents are formulated to remove heavy machining contamination.
Rotajet systems incorporate heated aqueous degreasing technology to improve cleaning performance.
Stage 3: Fresh Water Rinse
Clean water removes detergent residue and remaining contamination.
Stage 4: Component Drying
Hot air drying removes moisture before parts move to the next stage of production.
Aqueous Parts Washing Systems
Many modern industrial degreasing machines now use aqueous cleaning systems instead of traditional solvent cleaning methods.
Aqueous parts washing combines:
- heated water
- industrial detergents
- high-pressure spray cleaning
- filtration systems
These systems effectively remove:
- machining oil
- coolant residues
- metal swarf
- polishing compounds
Rotajet spray washing machines use aqueous cleaning technology, allowing manufacturers to clean components efficiently while reducing solvent usage and improving environmental compliance.
Types of Contamination on Machined Parts
Understanding the type of contamination helps determine the most suitable cleaning process.
Cutting Oils
Lubricants used during machining operations.
Machining Coolant
Water-based fluids used to control heat during cutting operations.
Metal Swarf
Small metal chips produced during machining.
Grinding Dust
Fine particles generated during grinding operations.

Industrial degreasing machines must remove all of these contaminants effectively.
Rotajet spray washing machines are designed specifically for removing machining oils and swarf from metal components.
Features of Modern Industrial Parts Washing Machines
Industrial degreasing machines incorporate several engineering features to improve cleaning performance.
Stainless Steel Construction
Rotajet industrial parts washing machines are manufactured from stainless steel, providing durability and corrosion resistance.
Heated Cleaning Systems
Heating improves detergent performance and helps remove heavy machining oils.
Filtration Systems
Modern parts washing machines include filtration systems to remove swarf and debris from cleaning fluids.
These systems may include:
- bag filters
- cartridge filters
- oil skimmers
- separation systems
Rotajet spray washing machines incorporate filtration systems to improve cleaning efficiency and extend cleaning fluid life.
