The cotton numbering system is also used for embroidery threads, regardless of the raw material. The Ne B indicates how many hanks, each of 840 yards (768,08 m) weigh 1 lb (English pound = 451,59 g).įormula: Ne B = number of hanks à 840 yds / 1bĮxample: 60 hanks of cotton yarn weighing 1 English pound make Ne B 60. You will then receive values such as nominal diameter, pitch. It is possible to calculate data for both internal and external threads. 120 m of the yarns weigh 1 g.Ĭotton threads are classified according to the English cotton numbering system with the abbreviation Ne B. We now offer you a program under the menu item Thread Tolerance Calculator, which calculates all important data for you after entering the thread designation and the thread tolerance. Example: Nm 120/2 means a twisted yarn of 2 yarns with a yarn count of Nm 120 each, i.e. Altering the Chip Load or RPM settings in any way without prior written approval from an authorized agent of CGC/Gorilla Mill will void any guarantee or warranty nor will CGC/Gorilla Mill or its agents be liable for any consequential damages due to said alteration. In the case of twisted yarns, the single yarn count is usually followed by the plying number behind a slash. The RPM and Chip Load that automatically populates in this calculator are the factory suggested parameters for running the desired tool. The formula of required time for tapping gives the required time for pusshing the tap inside and the formula of required time for cutting gives the required time for returning the tap. In the process of tapping internal threads are made with a tool which is called tap. Nm 100 means that 100 m of yarn weigh 1 g. The tool which is used in reaming preocess is called Reamer. It is the ratio of length in m to mass in g. The metric numbering with the symbol Nm indicates how many meters of a single yarn weigh 1 gram.
THREAD CALCULATION TOOL INSTALL
Install a 60 degree threading tool bit and set the height to the lathe center point.
THREAD CALCULATION TOOL HOW TO
Although the ticket number results from the Nm, it does not inform about the plying of the yarn. Explain how to calculate the pitch, depth, and minor diameter. These calculators will be useful for everyone and save time with the complex procedure involved to obtain the calculation results. The smaller the ticket number, the thicker the thread the larger the ticket number, the finer the thread. A tool perform calculations on the concepts and applications for Pitch calculations. The ticket number is used as an industry-specific indication of strength and is determined by the abbreviation No., Tkt. Therefore, there are several other numbering methods as a basis for the specification of the fineness: It is based in concept on Screwmez by Pete Worden. For the numbering of sewing threads, the tex system is recommended, but not mandatory. This tool can be used to calculate the correct measurement for a given thread using the three-wire method.
