HEAVY MACHINE TOOL PLANT (HMTP)

This plant was established in collaboration with SKODA of erstwhile, CSSR and equipped with

facilities for manufacturing heavy machines tools, both conventional and CNC version. It has

also design and R&D wing with high qualified and experienced engineers. The plant isequipped

with CNC hardening equipments. Subsequently the plant has also acquired technical know-how

for following agencies.

a) M/S HERCULUS of Germany for rail grinding machinesb) M/S HEGENSCHEIDT of Germany for railway lathesc) M/S O-M of Japan for vertical boresd) M/S BOEHRINGER of Germany for plane milling machine

The plant design and manufactures equipment for the following :

1. Special purpose railway machine tools2. CNC and Conventional machine tools in the medium and heavy range for the core

sectors and defiance like vertical turning and boring machine, planner, milling, etc..

Deep Hole Boring Machine :-Main Features

High rigidity Simple design Easy to maintain Suitable for BTA tooling Precision ground, Y-guide ways for sustained accuracy Efficient coolant system
