Plano milling machine

This is similar to a double housing planer but the tool can be milling tool. One of the machines is TNC (three axis turning centre) in which only one axis can be moved at a time. Thus round jobs cannot b machined here.

Another machine is CNC in which two axis can be moved simultaneously to machine round job. The length of the bed is 2800mm.

INSPECTION DEPARTMENT

In this department the all machined or finished part are inspected.

ASSEMBLY DEPARTMENT

It is a part of industries where whole parts of machine are assembled after inspection and final product is prepared.

GRINDING MACHINES : 1. CNC Double Disc Grinding Machine-GDS-

15/222. CNC Grinding Center -GCS-

175/2253. CNC Center Less Grinding Machine -GCL-

A OVER VIEW OF MACHINE ASSEMBLY

MAINTENANCE DAPARTMENT

• Maintenance is the work of keeping something in proper condition before and after use.

• They are 3- Types:- Break Down Maintenance Preventive Maintenance Corrective Maintenance

CONCLUSION

My personnel experienced in HMT-Ajmer signifies me that theoretical and bookish knowledge must be supplemented with the able practical knowledge.

And the companies of national pride like HMT must not be shut down or run in losses condition. Some measures must be taken to rise and solve out all the problems like decreasing the manufacturing time, The price of products of HMT-Ajmer is comparatively high so we must reduce it and the R&D team must be innovative and market oriented with increasing the investment from 0.01% to about 1% of their total turn over .
