CNC Machining Brass FAQs
Which quality standards do cnc brass parts comply with?
CNC milled brass products strictly comply with the following quality standards:
- ISO 9001 – a universal quality standard that outlines numerous quality management systems and processes.
- ASTM International – a quality standard agency that creates and publishes voluntary control according to a number of technical specifications for systems and products.
- CE Mark – a mark of quality, which proves the parts conform to the required health, environmental, and safety standards.
- PMPA – a quality standard agency, which oversees production of different types of precision machined products
What is the cutting speed for brass?
Cutting speeds for brass using a plain high speed steel cutter are 90-210 MPM (meters per minute) and 300-700 SFM (surface feet per minute).
Is brass easier to machine than aluminum?
Brass is one of the easiest materials to machine, especially in comparison to aluminum. Where aluminum can often stick to machining tools, brass seems to adhere to tools less during machining. It is a metal alloy made of copper and zinc and is one of the most highly used materials in the world, but is still underutilized in the US in machining.
What are tips for CNC machining brass?
These tips will help you experience more success when CNC machining brass:
- Carbide cutting tools or cutters with carbide inserts can improve the material removal rate and extend the tool life.
- Allow mills to run a higher speed.
- Use spindle liners to protect the equipment, workpiece, and machine operators.
- Faster machining speeds and higher quality in brass turning or milling can be achieved by reducing the clearance to damp vibration and eliminating the bar whip.
- Proper programming is essential in cnc machining brass, for example, using the proper G-code to set spindle speed and operations based on the requirements of your project.
