Machining Metal and Teflon Drawings

Modern manufacturing requires three essential elements: accurate machining drawings, expertise in machining metal components, and specialized technology in machining polytetrafluoroethylene (PTFE).

CNC Turning

CNC turning is a lathe machining technique used to remove material from cylindrical workpieces. During CNC turning, the workpiece is held in a rotating chuck at one end, while the tool moves horizontally to remove material across the diameter of the workpiece. Parts produced by CNC turning are typically axisymmetric, and common shapes include basic forms such as shafts and fasteners. Examples of parts produced by CNC turning include camshafts, crankshafts, custom containers, and hand tools such as hammers, punches, gauges, and screwdrivers.

CNC Milling

CNC milling is the process of removing material from a workpiece using a rotating tool. In CNC milling, the workpiece is fed into the tool in the same direction as the tool's rotation. A milling machine primarily consists of two components: a table that holds the workpiece and a spindle and toolholder that moves horizontally or vertically. Multi-point cutting tools, such as end mills, chamfer mills, face mills, and dovetail mills, are used to remove material from the workpiece. CNC milling is a highly practical process capable of producing more complex geometries than turning and is widely used in the manufacture of parts such as gears, electronic housings, and orthopedic implants.

CNC Drilling

CNC drilling is the process of creating cylindrical holes in a workpiece using a drill. During CNC drilling, the drill moves perpendicular to the workpiece surface, creating vertically aligned holes. However, special machine configurations and toolholders can also be used to create angular holes. Different types of drill bits serve various purposes. For example, spot drills are used to create shallow or pilot holes, while reamers are used to finish surfaces to achieve the exact dimensions of a previously drilled hole.

Scimitar EDM

Electrodischarge machining (EDM) is a process that uses spark erosion to cut features into a metal workpiece. In sinker EDM and wire EDM, the workpiece is immersed in a dielectric fluid, generating high-voltage sparks between it and a conductive electrode. These sparks melt the workpiece material, creating a cavity in the workpiece. Sinker EDM is particularly well-suited for precision machining applications, achieving tolerances as tight as +0.004 inches. It is widely used in the manufacture of precision plastic injection molds.
