The technologically shrewd world today focuses on precision. Be it the textile industry or medicine, agriculture or manufacture, aeronautics or oil and gas, packaging or mining, precision is of utmost importance today to stay in competition. Computer Numerical Controlled (CNC) machines are required to meet such high levels of precision engineering for milling operations, turning operations or both these operations combined in one machine. EDM or Electrical Discharge Machine is used in cases where high tolerance levels are required. The 4th axis EDM excels in this field. While talking about EDM and its variations including Sinker EDM, Wire EDM, Hole Popper or Small Hole EDM drill are of great importance here due to being typical.

EDM is capable of meeting high tolerance levels, as a process of removing metal from original metal for progressively meeting the dimension of parts manufactured. Melting or burning of metal is done by utilizing electric current in a very controlled manner. With the metal removal process being very precise, you can reach the required levels of intricate design and high order of tolerances. Professional engineering firms have sophisticated 4th axis EDM machines, for example the EDM drill and Charmilles wire EDM machines.

The “hole popper” or small hole EDM drill has a copper or brass electrode that’s used for blasting holes through the work. The EDM drill is quite similar to the Sinker variety of EDM except that the drill has a very aggressive current supply for blasting the hole. In contrast, the power supply of Sinker is more sensitive to protect the electrode.

About Idler Rolls

Many professional companies that manufacture precision products continue to remain the prime suppliers of both melt spinning and yarn texturing industry since 1993. Yarn handling is amongst the prominent areas the leading manufacturer Precision Parts Inc enjoys considerable experience, particularly as a main supplier to some of leading manufacturers of carpet yarn in the world. Idler rolls play a vital part in yarn extrusion. Moreover, these idler rolls operate at very high speeds; therefore, their balancing is of great significance.

Some of the latest CNC (Computer Numerical Control) machines are used for manufacturing these idler rolls. The large idler rolls are also called separator, pin rolls, and tension. The rolls contain both high speed and high precision ball bearings. A broad range of idler rolls is available to cater to the requirements of major extrusion lines, such as Barmag, Plantex, Filteco and Neumag.
