What is ABS CNC Machining?
ABS (Acrylonitrile Butadiene Styrene) is a widely used thermoplastic polymer known for its excellent impact resistance, toughness, and machinability. It is a lightweight, cost-effective engineering plastic commonly used in CNC machining for functional prototypes and end-use parts.
Application Of ABS CNC Machining
High Precision
ABS CNC Machining with ultra-precise tolerances (±0.005″ or better) for perfect fit and function.
Fast Turnaround
No need for expensive molds (unlike injection molding).
Superior Finish
Smoother than 3D printing, ready for painting/coating.
Material Versatility
Available in standard, flame-retardant, and glass-filled grades.

Notes
Spindle Speed (RPM)
10,000 - 20,000
Higher speeds for fine finishes, lower for roughing
Spindle Power (kW)
3 – 15
Depends on tool size and material removal rate
Feed Rate (mm/min)
500 – 3,000
Adjust based on tool diameter and depth of cut
Cutting Depth (mm)
0.5 – 5
Deeper cuts for roughing, shallow for finishing
Cutting Width (mm)
0.5 – 10 (50% stepover)
Full-width cuts possible for small tools
Machining Accuracy
±0.01 - ±0.05 mm
Tighter tolerances achievable with fine-tuning
Surface Roughness (Ra)
0.8 – 3.2 µm
Finer finishes with high RPM & low feed
Tool Type
2-4 Flute Carbide End Mills
Sharp, polished flutes reduce melting
Tool Diameter (mm)
1 – 12
Smaller tools for detail, larger for roughing
Coolant Type
Air Blast / Dry Machining
Minimal coolant needed (ABS is soft)
Chip Load (mm/tooth)
0.05 – 0.2
Prevents overheating and gumming
Ramp Angle (°)
3 – 10
Gradual entry reduces tool stress
Stepover
30% - 70%
Lower for finishing, higher for roughing
