CNC machining of aluminum presents unique challenges tied to its diverse alloy properties and machining behavior. Its high thermal conductivity causes heat to dissipate rapidly, but localized heat at the cutting edge can still soften the material, leading to built-up edge (BUE) and poor surface finish if feed rates and spindle speeds are not optimized.
CNC machining of PVDF (polyvinylidene fluoride) presents unique challenges stemming from its exceptional material properties. Its high chemical resistance and inertness—key advantages for chemical processing applications—make it highly abrasive, accelerating tool wear and reducing tool life compared to softer plastics. PVDF’s combination of mechanical strength and toughness causes it to deform under cutting forces, leading
CNC machining of LDPE (low-density polyethylene) comes with unique challenges rooted in its material properties. Its high flexibility and elasticity cause it to deform under cutting forces, leading to poor dimensional accuracy and burring if machining parameters are not optimized. LDPE’s low melting point (105-115°C) makes it prone to melting at the cutting edge, resulting
CNC machining of Bakelite, a pioneering thermosetting plastic, presents unique challenges that manufacturers often face. Its hard, brittle nature makes it prone to chipping and cracking during milling or drilling, especially when using improper tool geometry or aggressive machining parameters. Bakelite’s high mechanical strength and low toughness cause it to shatter under sudden cutting forces,
