Custom CNC machining PP part

• Material Properties: PP has good chemical resistance, heat resistance, and electrical insulation properties. It is lightweight, tough, and commonly used in applications requiring corrosion resistance, weight reduction, and electrical insulation.
• Machining Challenges: PP has a high thermal expansion coefficient, which makes it prone to deformation under heat during machining. Therefore, it is essential to carefully control cutting speed and feed rate to prevent the material from softening or deforming due to heat buildup.
• Cooling and Lubrication: Since PP is a thermoplastic, friction during machining can generate heat, leading to deformation. Proper cooling and lubrication are necessary to maintain machining accuracy.
• Fixtures and Clamping: PP is a soft material and can easily deform under external pressure during machining. Appropriate fixturing systems are needed to avoid applying excessive pressure during the process.
• Surface Finish: Achieving a good surface finish on PP parts is relatively easy through machining. However, the choice of tool geometry and cutting parameters must be carefully considered to avoid leaving machining marks on the surface.
