Broaching is a popular and highly successful process which is used in many industries like fasteners, gears, automotive, agriculture, industrial manufacturing, oil & gas, heavy equipment and aerospace.
Broaching Process
Multi-tooth forming tools move linearly relative to the workpiece in the direction of the tool axis. Broaching is a process that can be used to machine internal profiles, grooves and complex geometric shapes with high precision and productivity.
The choice of cutting fluid to use when broaching depends on the workpiece and tool material and the operating conditions of the machine used.
Cutting fluids today contain a wide range of specialty chemicals designed to provide specific levels of lubricity, surface activity, stability activity and antiperspirant properties.
Designing & oil Parameters:
We at Hard Castle Petrofer Ltd design and develop suitable range of broaching oils after thoroughly understanding the broaching process considering following critical parameters.
- Machine Speed
- Broach type and material
- Work Piece material
- Tool life expected
- Broach components finish
- Load carrying capacity, Lubricity and Coefficient of Friction expected
- Operational Severity
- Carefully selected base fluids and performance additives
An effective Cutting Oil should:
All metalworking fluids eventually become contaminated and must be disposed of, even if the user selects high quality fluids and uses proper fluid management. With that in mind, we also recommend some simple coolant system cleaning procedures that can extend coolant and tool life and improve the overall broaching process.
Considering the broaching process and machine operating conditions, we find that most broaching processes are slow cuts with high pressure in the cutting zone and large depths of cut. Tribological conditions also require more boundary lubrication. Therefore, the broaching process requires more lubrication than cooling to reduce friction between the tool and chip contact and avoid built-up edge on the tool surface. These requirements are met primarily through the selection of pure cutting fluids that offer maximum lubricity compared to water-soluble types.
