Our services include design, prototyping, short and full run production manufacturing, mold impressions and detail assemblies, using the latest in CNC machinery and technology.
At SVEM, we operate state of the art computer numerical control (CNC) machines. These machine tools are controlled by programmed commands, coded by our engineers. The first NC machines were built in the 1940s and 1950s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern CNC machine tools that have revolutionized the machining processes.
Among our CNC platforms are precision mills, which come in two basic forms, horizontal and vertical, referring to the orientation of the main spindle. Unlike a drill press, which holds the workpiece stationary as the drill moves axially to penetrate the material, milling machines also move the workpiece radially against the rotating milling cutter, which cuts on its sides as well as its tip. Matrix XR and VR series Robodrills, YCM XV 1020As, 560A, Doosan DNM 400 and DNM 500, are some of our CNC mills.
Multiaxis machining is a process where CNC tools that move in 4 or more ways are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. Typical CNC tools support translation in 3 axes; multiaxis machines used at SVEM also support rotation around one or multiple axes. Our engineers also make use of CAM (computer aided manufacturing) software systems to program our multiaxis machines including software that can automatically convert 3-axis toolpaths into 5-axis toolpaths.
While the programming is done by engineers, skilled machinists work directly with the machines, including metalworking lathes such as the Takisawa U 110 EX series, the Doosan Lynx 220 and others, to precisely machine both metals and plastics. These machines are very versatile and are used in a wide range of applications, with a broad range of materials. They are usually simply called lathes, because these machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits.
This a process we often use to create rotational parts by cutting away unwanted material. This requires a turning machine (lathe), workpiece, fixture, and cutting tool. The workpiece is secured to the fixture, itself attached to the turning machine, and allowed to rotate at high speeds. The cutter is typically a single-point cutting tool that is also secured in the machine, although some operations make use of multi-point tools. The cutting tool feeds into the rotating workpiece and removes material in the form of small chips to create the desired shape.
