Material Properties & Machinability Profile
Brass C36000 (Free-Cutting) is classified as a Leaded Free-Cutting Brass widely specified for mission-critical components requiring High-speed turned fittings, pneumatic valve bodies, architectural lock cylinders, and instrument pins..
Engineering Kinematics & Cutting Parameters
- Material Hardness: 65-80 HRB.
- Recommended Cutting Speed ($V_c$): 200 - 600 m/min with dedicated substrate coatings.
- Chip Load ($f_z$): Maintained between 0.10 - 0.30 mm/tooth to prevent tool rubbing or excessive mechanical shock.
- Machinability Challenge: 100% machinability rating standard; microscopic lead globules break chips instantaneously, allowing maximum spindle feeds.
- Tooling Strategy: Employs high-pressure flood coolant (>= 30 bar) and micro-grain carbide or specialized inserts with positive rake geometries.
