ABSTRACT

Hindustan Machine Tools is the major industry of the modem era because of its wide
application in automobile, aerodynamic sector etc. For the manufacturing of machine tools
highly equipped and modern machinery are develop in 21st century like CNC’s, which have
been illustrated in the project report. The process of making a grinding machine generally
requires study of materials and its behavior in presence of heat, a overview of material used
in making a grinding machine is given. In the steps for manufacturing a class first grinding
machine the important aspects is reading the drawing and carry out the corresponding
operation to get the desired grinding machine, in the report a job piece 305 E outer is
analyzed with its cycle time and many such calculations are carried out.Last but not the least,
rather the most prominent think being the quality control aspect on industry and this enable
an individual or organization to keep a check over the manufacturing material this aspect
have been discussed in the culmination chapter. Industrial training is part and parcel of every
technical course and gives a face or form to all the theoretical knowledge we gain in our
classroom. We get to have a virtual experience of the processes, methods, objects and
phenomenon which used to be just an imaginary picture in our minds. It also gives an
exposure to the environment of the industries and workshops which are virtual components of
our professional life. We too were provided with this opportunity this summer.
We are thankful to our college administration that handed this invaluable chance to us and at
the same time we pay our regards to the administration of HMT AJMER (Machine Tools
Division) that proved to be a great supporting force for the fulfillment of the purpose. The
officials and the workers of the firm provided us with the best of their attention and share
ample of knowledge of their concerned field with us.

governed by a high pressure relief value. Which is set by us before the machine leaves
our works.
2. From the high pressure relief value the oil is taken to the distribution pipes in the m/c
where the oil devides and the pressurized oil passes through appropriate control
values to hydraulically operated tail-stock.
3. The circuit oil returns line pressure is also utilized for lubricating the table and wheel
head guide ways. A pressure gauge is provided on the hydraulic power pack to
indicate the pressure in the system.

CHAPTER 5
CONCLUSION
Advanced machine tools are vital to the realization of tomorrow’s critical technologies. In the
efforts to survive in this highly competitive environment, companies are engaging in various
initiatives such as expanding their market share by strengthening their sales and production bases
through M&A, developing new products and functions that will give them an edge over other
makers, boosting resilience against recession through production efficiency, and providing fee-
paying after services. At present, differences in competitiveness among companies in the industry
are beginning to become evident. Predictions of economic growth for the machine tool industry
are conservative, but positive. A new spirit of cooperation exists among industry, academia and
government to develop programs that best utilize research resources to help industry resolve
problems in the way of progress. There are even signs that training, a long neglected issue for the
machine tool industry, is getting fresh attention. Meanwhile, pressures for lower cost, greater
productivity, and improved quality are forcing even the most conservative machine-tool users to
re-evaluate their equipment and proceduresof CNC machine working.
