THOUGHT ON EMERGING TRENDS IN MACHINE TOOL INDUSTRY INDIA

Indian economy is one of the fastest growing in the world behind china. The rise in economy of India is outcome of the transition from the status of developing country to developed. A lot of factors are behind this and is very difficult to pin point each. It may be due to the decrease in inflation, rise in exports volume, increased agriculture yield, better employment, education etc.

One of the major driving force is Industry. If we talk about Indian machine tools industry then it has grown from leaps and bounces. Today we can say that, made in India drill machines are well accepted in the world due to its good quality and competitive price. We can see a lot of developments/ automation has taken place in the Drilling machine. The pillar drilling machine or drill press is accepted as the most widely used machine tool in the Industry and find their application in Automotive, Aerospace, Agricultural Equipment manufacturers & Machine tool Industries etc.

Bench Drilling Machines are used for creating hole. The drive from motor is given to the tool (Drill) held in machine spindle by means of a Belt driven Stepped pulley (in case of Belt Driven machines): or Gear drive (in case of Geared Head). The cutting Speed (rpm) is selected depending upon the size of Drill. Larger the size of Drill slower the cutting speed required. Example: In steel the normal maximum cutting speed required will not exceed 8000rpm for drills around 1mm diameter. Below 1.0mm diameter recommended drilling speeds start to slow down. Now the range of cutting speeds is limited in these machines. In case of a belt driven stepped pulley drive, the no of steps of pulley determines the range of speeds available. In case of Geared head the gear ratio determines the range of cutting speeds available. The feed or Downward movement of the Drill is achieved by means of operator applying force on the Quill & Gear arrangement by means of a Handle in case of a manual feed Drilling Machines and by engaging the gear arrangement in case of an Autofeed Drilling machine. The production achieved is much more in the Autofeed Drill machine as  the operator is not required to apply the force which is  transmitted by means of gear arrangement. (there is limitation of feed depending upon the gear ratio)

These type of Pillar Drilling machines are now being suppressed by new generation of Hi tech Machines. These new generation Machines includes Hydraulic / Pneumatic Autofeed Drilling machines and are offering latest technologies to the customers. They are very reliable high output machines and also solves the problem of need of highly skilled labour. Since these machines are so simple to operate that an unskilled labour can be made to operate this machine with some basic training of few hours.Also a single operator can operate more than one machine at a time thus reducing the labour cost.

These Drill machines comes with:

·         Belt drive (variable speed pulleys) and Electronic variable speed control : These are very economical and reliable method of speed change and allows operator to find the ideal speed without changing the belt. The speed ratio is infinite and can be changed very quickly. Electronic variable speed control gives a digital display of speed.

·         Autofeed by means of a Hydraulic/ pneumatic power pack: With this system the feed can beadjusted within microns (infinitely variable speed) as per the job and thus increases the production. The entire system is connected to a electronic panel having push buttons. On pressing cycle on the Drill descends towards the job with high speed and then feed mode is activated and once the desired depth is achieved the Drill traverse back quickly, Thus reducing the cycle time. These machines can be customised as per the customer’s job and tooling solutions along with work holding fixtures are also designed.

Indian Engg Corp is having a experience of more than 50 years in manufacturing Drilling machines  under brand “ITCO” and is a well know name in Indian market. We are having a team of highly experienced and  talented Engineers form all the fields and are constantly working with new technologies providing the customers with high-end products at an affordable cost.
