General Specification:


The Rod Threading Machine is used for Cutting External Thread on Rods by Chasing method. HSS Tangential Chasers are used as cutters. Rod remains stationery and Die Head rotates. Matric, BSP, BSPT, NPT, UNF,UNC, BSW, Acme Threads B.S.F etc. threads can be cut on this machine depending upon the type of Chasers. The machine mainly consists the following:-
 Base  Head Stock  Saddle  Bed or Pillar Type Clamping Vice  Die Head.

THE ROD THREADING MACHINES are designed to give maximum efficiency and reliable performance under the most severe conditions of service with minimum maintenance cost. All the necessary requirements are combined in this model to from the basic fundamentals of correct threading. All the gears are made of case hardened steel with extra large face with and tooth thickness and cut on hobbing machine for noiseless operation even at high speed. Naturally the are built with high standards of workmanship, material and quality so closely associated with COMPANY TRADITION.

DESIGN & WORKMANSHIP: The National Cutting Tools thread cutting machines are designed to produce quality threads within the to lerance for which they were intended.

HEAD STOCK: A heavy duty geared Head Box is of best quality casting providing support to the spindle bearings. The box is of gear type, lubricated, fitted with three extra heavy duty bearings.

THE BED: The bed is pillar type having two pillars made of best quality steel nicely finished & duly hard chrome plated in the most modern hard chrome plating unit.

THE SADDLE: The Saddle is fitted on two pillers very precisely. It runs on pillars very smoothly and accurately to the Head Stock alignment.

The APRON: The apron gives movement to the saddle with head transfer along with pillars through steel rack and pinion arrangements. It's all gears are made of best quality steel.

VICE JAWS: The vice jaws made from the best quality alloy steel are fitted on the saddle well aligned with the head stock center fitted in a heavy duty box type vice. The jaws are heat treated. The movements of jaws are controlled by a screw on the saddle.

Threading Tangential Chaser

Threading Tangential Chaser


NCT Tangential Chasers are manufactured from imported High Speed Steel which must pass exacting metallurgical standard. Experienced heat treatment with the automatic imported heat treatment plant and imported Testing equipments, assures that they will perform satisfactorily in service and produce quality threads within the tolerance for which they ware intended.

NCT Chaser are interchangeable. If one Pc. Of a chaser set is damaged & is beyond use. Then same No. pc. Of the other chaser set lying in stock may be used and there will not be any difference in threading performance and the damaged set can be replaced without the necessity of replacing entire set.
