What are the advantages of ground carbide inserts over pressed carbide inserts?
Ground carbide inserts have several advantages over pressed carbide inserts including durability, precision, and chip control.
Durability
Ground carbide inserts are typically made from a solid piece of carbide, which makes them more durable and resistant to wear compared to pressed carbide inserts. This solidity ensures that ground carbide inserts can withstand heavy usage and last longer without needing frequent replacements.
Precision
Ground carbide inserts are manufactured using precision grinding techniques, which result in a high level of dimensional accuracy and surface finish. This high precision allows for better accuracy in machining applications, leading to smooth and precise cuts with minimal errors.
Chip Control
Ground carbide inserts can be designed with specialized chip breakers and geometries that aid in chip control and improve machining efficiency. These features help in breaking and managing chips effectively during the machining process, leading to better chip evacuation and reduced tool wear.
In contrast, pressed carbide inserts are made by pressing powdered carbide into the desired shape and then sintering it. While they can be cost-effective for certain applications, they may not offer the same level of durability, precision, and chip control as ground carbide inserts.
