Tecnicrafts collets and guide bushings are exclusively used for Swiss Turning applications on Citizen-Cincom, Tsugami, Star, Tornos, Hanwha, Traub, Hardinge, Manurhin-Kmx, Miyano, Nomura and other popular machine brands and are widely recognized and accepted by customers in Europe and Asia.
The collets are offered in steel- and carbide-lined versions with grooved, smooth, serrated bores in standard and long-nose types. Tecnicrafts produces special collets such as V-line, U-line, over-grip Collets, for positive gripping of delicate parts without marks. The Ultra Precision (XP) W-type collets are available for tool grinding applications on machines like Rollomatic, Anca and Ewag . Other collets offered includes 5C and 16C types.
Tecnicrafts guide bushings are generally offered in carbide lining having Super Finish bore with roughness value of less than 0.4 micron. These special guide bushings include U-line, extended nose and long carbide bores (Max Land) for special turning applications.
The bar feeder collets are available for various bar feeders like Fedek, LNS, Ikura-seiki, Iemca, Citizen and FMB.
All collets and guide bushings are offered in standard and XP grades. The bore profile includes round, square, hexagon, rectangular and profile bores as per customer drawings.

computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
Measure of length that is equal to one-millionth of a meter.
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
