General Specification:
Pillar Type Hydraulic Threading Machine comes with self opening the die
head with head stock gears hardened with power pack, with one hydraulic
cylinder for lead screw box nut engaging, one hydraulic pipe clamping
cylinder and one hydraulic cylinder for die-head opening with micro
switches with automation with control panel.
The Pipe Threading Machine is used for Cutting External Thread on Pipes
by Chasing method. HSS Tangential Chasers are used as cutters. Pipe
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 PIPE 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
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. Read More
