Platinum Tooling Now Imports Swiss-Type Collets and Guide Bushings from Tecnicrafts
Platinum Tooling Technologies
Tecnicrafts, located in India, manufactures collets and guide bushings for use on Marubeni Citizen-Cincom, Tsugami, Star, Tornos, Hanwha, Traub, Hardinge, Manurhin-Kmx, Miyano, Nomura and other Swiss-type machine brands.
The collets are offered in steel- and carbide-lined versions with grooved, smooth and serrated bores in standard and long-nose types. Special collets such as V-line, U-line and over-grip collets are designed for positive gripping on delicate parts without leaving marks. Ultra precision (XP) W-type collets are available for tool grinding applications on machines from such brands as Rollomatic, Anca and Ewag. Other collets offered include 5C and 16C types.
Tecnicrafts’ guide bushings have a carbide lining, providing afinish bore with a roughness value of less than 0.4 micron. These guide bushings include U-line, extended-nose and long carbide bores (Max Land) for special turning applications.
All collets and guide bushings are offered in standard and ultra-precision grades. The bore profile includes round, square, hexagon, rectangular and profile bores, as per user drawings.
Don't assume the standard chuck is the right workholding for every lathe application.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
