Machining
Machining that unlocks the
full potential
of forged parts
At Forgeem, machining is the final and essential step that brings out the full performance of each forged component. Specialising in copper and brass — high-performance, technically demanding materials — our team approaches every cut with precision, expertise, and adaptability.
Using cutting-edge digital machinery, carefully selected tooling, and in-depth knowledge of non-ferrous metal behaviour, we deliver parts with exact tolerances, consistent surface finishes, and flawless functionality. This commitment to precision drives our teams every day as they transform raw materials into high-performance components.
Mastering the machining
of forged parts
Copper and brass present unique challenges during machining — from adhesion and heat sensitivity to tool wear.
At Forgeem, our expertise allows us to tackle these constraints with precision and consistency.
Anticipating copper adhesion
While copper is soft, ductile, and highly malleable, it tends to exhibit “sticky” behaviour during machining, leading to material build-up on cutting tools. To counter this, we apply carefully selected cutting angles, typically using carbide tools, and operate at moderate cutting speeds. This approach ensures a clean surface finish from the very first pass.
CONTROLLING TEMPERATURE
The high thermal conductivity of copper and brass can cause rapid heating of cutting tools. Effective cooling is therefore crucial to regulate temperature, minimise deformation, and extend tool life.
CONTROLLING HARDENING
During machining, copper and forged brass can harden upon contact with cutting tools. To prevent this and preserve part integrity, we use ultra-sharp tools, adjust cutting speeds carefully, and, when needed, perform multiple successive passes.
OPTIMISING WORKPIECE HOLDING
The machining jaws are specifically designed for each part we forge. Workpiece holding is planned from the industrialisation phase of our forging process to ensure perfect compatibility and optimal clamping.
Key steps
Machining copper and brass requires meticulous preparation and rigorous control at every stage to ensure maximum precision and full compliance with specifications.
Before machining begins, tools are preset on dedicated benches, customised jaws are prepared, and the machine is fully configured for your specific parts.
Depending on the complexity and volume of the parts, we select the most suitable equipment — from CNC machining centres and CNC lathes to rotary transfer machines.
Each part undergoes rigorous inspection using a three-dimensional measuring machine to ensure full compliance with design specifications.
Copper and brass chips generated during machining are carefully collected, sorted, and sent to our specialised suppliers for recycling.
Following precision machining, surface treatments are applied to enhance the mechanical properties and durability of the parts. Discover more about this key step on our dedicated page.
