The Popularity Of Plastic Routing And Drilling


Plastic machining has become more popular than ever since plastics are arguably the most common material job shops and machine shops throughout North America. Plastic routing is simpler than the routing of some other materials, since plastics cause minimal vibration. Plastic machining commonly uses materials such as Acetal, Delrin, Hydex, UHMW, nylon, polycarbonate, polyurethane, and polyethylene terephtalate. It is easy to use plastic drill bits and other tools with these materials, they provide a predictable performance, they are durable, and they have good electrical properties. Plastic drill bits might even be replacing their metal counterparts since this material has become so popular, particularly soft plastics.

Soft plastic machining typically utilizes O flute routers that tends to curl a chip during the machining process. This plastic routing process was designed to attack the soft plastics with a high rake and low clearance geometry that actually carves the material while providing an excellent finish. O flute plastic drill bits are common, which are manufactured from micro grain solid carbide materials in straight and spiral configurations.

Plastic machining in flat sheet or block applications commonly utilizes upcut or right hand spirals, however, because of the need to evacuate chips in an upward direction. These plastic drill bits are available in either single or double edge cutting diameters. A single edged plastic routing or drilling tool is the best choice for most applications, though, because it can accommodate situations that require smaller diameters. There are different plastic materials for every purpose, which is why plastic machining has become so common in job shops and machine shops around the country. It is also why there are so many different tools for every imaginable plastic cutting, routing and drilling job that could take place in the industrial world. It has long been considered the material of the future, but it's easy to see that plastic is the material of right now.
