What Is Polyoxymethylene (POM) Usinagem CNC?
Polyoxymethylene (POM), also known as acetal resin, is a high-performance thermoplastic e engineering polymer prized for its exceptional mechanical properties. Its unique chemical structure—composed of repeating oxymethylene units—gives it high strength, rigidez, and resistance to wear and chemicals.
Usinagem CNC (Computer Numerical Control Machining) is a subtractive manufacturing process that uses computerized tools to shape materials with unmatched precision. When combined, Usinagem CNC POM leverages the polymer’s natural advantages to create complex, dimensionally stable parts for diverse industries. Below is a breakdown of POM’s key mechanical properties that make it ideal for CNC machining:
| Mechanical Property | Valor típico (ASTM Standard) | Key Benefit for CNC Machining |
| Tensile Strength | 60 MPa (ASTM D638) | Enables creation of strong, load-bearing parts |
| Flexural Modulus | 2.8 GPa (ASTM D790) | Ensures rigidity in precision components |
| Impact Strength | 6 kJ/m² (ASTM D256) | Resists breakage during machining and end-use |
| Coefficient of Friction | 0.15 (contra. aço, dry) | Reduces wear on tools and finished parts |
| Heat Deflection Temperature (HDT) | 110°C (ASTM D648, 1.82 MPa) | Maintains shape in high-temperature environments |
