Engineering Industries: Machine Tools, Industrial Machinery, Agricultural Machinery

Geography › Industry · Topic 13.3

Engineering industries make machines and capital goods, and their products range from machine tools and industrial machinery to tractors and pumps. They use steel and other metals, so they stand near steel centres, power sources and large markets. They create the equipment of other industries, and their strength shows how advanced a country's industry is.

Where Does It Fit?

This topic follows textiles and takes the industry that makes machines for all others. It uses steel, and it leads to the vehicle, rail, ship and aircraft industries. Previous topic: Textile Industry: Cotton, Woollen, Silk, Synthetic and Man-Made Fibre – Location, Trends, Distribution, Production. Next topic: Automobile, Railway Car, Locomotive, Shipbuilding and Aircraft Industries.

What Are the Types of Engineering Industries?

Type	Products	Notes
Machine tools	Lathes, milling, drilling and grinding machines, CNC machines	The mother of machines: they make other machines; precision work
Industrial machinery	Boilers, turbines, generators, transformers, cranes, mining and cement machinery, textile machinery	Heavy electrical and mechanical goods; heavy engineering
Agricultural machinery	Tractors, tillers, harvesters, threshers, seed drills, pumps	Mechanise farming; lowers labour needs
Transport equipment	Vehicles, locomotives, ships, aircraft	Described in Automobile, Railway Car, Locomotive, Shipbuilding and Aircraft Industries

Engineering is divided into heavy engineering, which makes big equipment in small numbers, and light engineering, which makes smaller goods in large numbers, such as pumps, fans, sewing machines and tools.

How Are Engineering Industries Located?

Steel and metals: engineering units stand near steel plants, as at Ranchi, Jamshedpur, Durgapur and Bhilai, because steel is bulky and costly to move. See coking coal, limestone, water Process Blast furnace to pig iron to steel Largest producer China,…">Iron and Steel Industry: Production Process, Location, Distribution, Global Production, International Trade.
Skilled labour: machine tools need trained workers and research, which is why they cluster in large cities such as Bengaluru, Pune and Ludhiana.
Power and markets: heavy electrical goods stand near power projects and big markets, and agricultural machinery near farm regions of Punjab, Haryana and Tamil Nadu.
Finance and policy: in India, the government set up public sector units after independence to build core capacity, and the private sector has since grown large.
World pattern: Germany, Japan, Switzerland, Italy, the United States and China lead in machine tools. The Ruhr, the Midlands of England, the Great Lakes region and the cities of Japan are old engineering regions.

Where Are the Engineering Industries of India?

Machine tools: Hindustan Machine Tools (HMT), set up in 1953 at Bengaluru, with units at Pinjore, Kalamassery, Hyderabad and Ajmer, started the sector. Bengaluru, Pune, Ludhiana and Rajkot now have many private makers.
Heavy engineering: Heavy Engineering Corporation at Ranchi (1958) makes equipment for steel, mining and power. Bharat Heavy Electricals Limited (BHEL), formed in 1964 with plants at Bhopal, Haridwar, Tiruchirappalli, Hyderabad and Jhansi, makes boilers, turbines and transformers.
Mining machinery: Bharat Earth Movers at Bengaluru and Mining and Allied Machinery Corporation at Durgapur.
Agricultural machinery: India is among the largest tractor makers in the world. Tractor plants are at Chennai, Faridabad, Mohali, Jalandhar, Nashik and Pune, and the sector serves the farmers of the north-west and south.
Clusters: Rajkot (diesel engines), Coimbatore (pumps and motors), Ludhiana (bicycle parts and hand tools) and Jalandhar (sports and tools) are well-known small and medium clusters.
Challenges: imports of machine tools and capital goods from China and Germany, low investment in research, and the need for high-precision manufacturing. The Capital Goods Policy of 2016 and the Make in India programme of 2014 aim to raise domestic capacity.

Production and import numbers differ each year, so check the latest data before quoting them.

Why Do Engineering Industries Matter for Development?

Capital base: an economy that makes its own machine tools, turbines and tractors spends less foreign exchange on imports and can set up new factories faster.
Employment: engineering units, from large public sector plants to small workshops, employ skilled and semi-skilled workers in large numbers, and small units supply parts to the large ones.
Linkages: demand from railways, power, defence, mining and farming keeps the sector busy, and its products raise productivity in these fields. Mechanised farm tools raise yields and release labour for other work.
Technology: precision machining, computer controlled tools and automation spread new skills to other industries, and exports of engineering goods earn foreign exchange.

Frequently Asked Questions

Why are machine tools called the mother of machines?

Machine tools are called the mother of machines because they are power-driven tools that shape, cut, drill and grind metal, and so they are used to make every other machine. A country that makes its own machine tools can build its own factories, which makes this sector the foundation of industrial independence.

What are the main types of engineering industries?

The main engineering industries make machine tools, industrial machinery, agricultural machinery and transport equipment. Industrial machinery includes boilers, turbines, generators and mining equipment, while agricultural machinery includes tractors, harvesters and pumps. Transport equipment covers vehicles, locomotives, ships and aircraft, and the whole group depends on steel and skilled workers.

Where was Hindustan Machine Tools established?

Hindustan Machine Tools, a public sector company, was established in 1953 at Bengaluru in Karnataka to make machine tools such as lathes and milling machines. It later opened units at Pinjore, Kalamassery, Hyderabad and Ajmer, and Bengaluru became a leading centre of precision engineering and aerospace industry.

What does Bharat Heavy Electricals Limited make?

Bharat Heavy Electricals Limited, formed in 1964, makes power-generation equipment such as boilers, steam and gas turbines, generators and transformers, along with railway and industrial equipment. Its plants are at Bhopal, Haridwar, Tiruchirappalli, Hyderabad and Jhansi, and its products supply thermal, hydro and nuclear power stations in India and abroad.

Which Indian cities are known for engineering clusters?

Rajkot is known for diesel engines, Coimbatore for pumps and motors, Ludhiana for bicycle parts and hand tools, and Jalandhar for sports goods and tools. Bengaluru and Pune have precision engineering and machine tools. These clusters have many small and medium units that supply parts to large manufacturers.
