Finishing machines are used for the finishing process that is carried out on parts for the purposes of cleaning, deburring, polishing and separation of parts. There are many types of finishing machines. The two important and widely used ones are the tumbling barrel machines and the vibratory finishing machines. In the tumbling variety, a huge barrel holds the parts and finishing media, compounds and water. In the vibratory finishing machines, there are usually tubs or bowls that undergo a shaking action at a particular speed. The shaking action is caused by a shaft that is attached to the tub or bowl.
The vibratory finishing machines come as large floor models (that can be fixed to the floor) or as smaller bench models (that are fixed on tables or benches). When the machine shakes at a high rate of speed, it causes the parts and the media to rub against each other thus resulting in cleaning and polishing. Using the vibrating machines, it is possible to get a very precise cutting of burrs and parts. They are also very effective in removing debris and dirt lodged in nooks and crannies, like a bore for instance. This sort of cleaning is not possible in a tumbling barrel. Vibratory finishing machines are ideally suited for use on delicate and intricate parts; also for large and bulky surfaces like wing spans - because they have high speeds combined with very short strokes. This provides powerful finishing but at the same time places very less stress on the parts. Vibratory finishing machines can be automated or semi automated quite easily and are good for continuous or batch processing.
Finishing or deburring media are materials that provide an abrasive action on parts to aid in the finishing process. They can be natural or man made. They come in different shapes and sizes depending on the requirements. When media is used in finishing machines, they accomplish finishing tasks like cleaning of oils, grease, dirt, grime etc and deburring of jagged edges or removing extra material from parts. Natural deburring media like walnut shells and corn cob media are made from naturally available material - they are non toxic, environment friendly, reusable and cost effective.
Man made deburring media like ceramic media and plastic deburring media are used for heavy and aggressive finishing. They come in different shapes and sizes. Some of the standard shapes found in the deburring media are cones, cylinders, pyramids, three headed stars, triangles etc. These shapes aid in polishing and cleaning hard to reach recesses in the parts. Depending on the shape and size of the holes in the parts, the shape of the media is chosen. If the part has a complex design with many corners having different shapes, then a combination of media shapes can be used to achieve uniform finish in the parts. Companies having a vast experience in the finishing industry generally have the expertise to find tailor made solutions to any deburring requirements.

The first moving machines that could be considered Tractorswere steam driven machines developed in the 1870's. It was from these steam driven machines that the farm tractors of today developed.
Two men who independently worked on steam driven machines were Benjamin Hold and Daniel Best around the 1890's. They were both successful. In 1904 Daniel Holt was successful at his first steam driven track type tractor, which was further developed into a gas driven track type tractor in 1906. Daniel Best and Benjamin Holt combined talents and Caterpillar Tractor Co. was launched in 1925. This merger was successful and Caterpillar Tractor Co. was supplying diesel powered tractors in 1931, from its assembly line in Illinois, USA.
Today, Caterpillar or Cat as it is known is today the world largest supplier of construction, mining equipment, diesel engines, gas engines, and gas turbines. Both Caterpillar and Cat are registered trademarks of the said company.
Caterpillar has expanded its services, and today its services includes Caterpillar Logistics Services, which ensured timely delivery of quality Caterpillar® parts to most parts of the globe. Cat Financial caters for financing of equipment purchases for eligible companies and individuals. Cat Reman (abbreviation for re manufactured) restores salvage machines to OEM specifications, or salvaged parts to OEM specifications for resale purposes. Cat Reman is backed by the Caterpillar original equipment warranty of two(2) years unlimited use warranty on new or Cat reman parts. For companies or individuals which/who prefers to rent equipment rather than buy, Caterpillar's "The Rental Store" is available. Machines can be rented on a contract basis. Sometimes this rental agreement includes that Cat provides an operator. In most cases, the maintenance of the machines is not the responsibility of the renter. This agreement allows the renter/company to focus on production or construction, while machine maintenance is Caterpillar's responsibility.
Recent acquisitions and mergers has established Caterpillar as one of the world's largest leaders in construction machines, marine engines, generating sets and gas turbines.
F.G Wilson was acquired in 1999. Emerson Electric, the owner of the F.G Wilson Generating Sets Company was joined with Caterpillar, thus expanding the line of products offered.
Mak Marine, the world largest manufacturer of large diesel marine engines in Germany, was acquired and is now named Caterpillar Motoren GmbH & Co. KG, with its headquarters in Hamburg, Germany.
The British renown engine company named after its owner Frank Perkins (born in Peterborough, England in 1889), Perkins engines are reliably used for many applications, including ag equipment from Massey Ferguson, industrial applications, power units, in generator sets, marine applications, and in the popular Caterpillar backhoe 416 series. These are fondly referred to as "Perkipillar" engines by some machine shops and engineers. Perkins is now owned by Caterpillar.
Even though many may see this company as an engine and machine company, Progress Rail®, now a subsidiary of Caterpillar company, is a major supplier of rail products and services within the USA, Canada and Mexico.
And finally, Solar Turbines, the manufacturer of industrial gas turbines for power generation, compression and pumping systems, was acquired in 1981, making it a wholly owned subsidiary.

Excavators Loaders can be of two types: 1- Backhoe Loaders, and 2- Wheel Loaders.
Backhoe
A backhoe, also called a rear actor or back actor, is a piece of excavating equipment consisting of a digging bucket on the end of an articulated arm (also called a stick or dipper). Modern backhoes are powered by hydraulics. They are typically mounted on the back of a tractor or front loader. (Similar attachments for skid loaders are still called backhoes even though they are mounted on the front of the vehicle). A backhoe attached to a swiveling cab on top of tracks is called an excavator.
Backhoe Loader
Backhoe loader, also called a Loader backhoe, is an engineering vehicle, which consists of a tractor, front shovelucket and small backhoe in the rear. Due to its relatively small size and versatility, backhoe loaders are very common in urban engineering and small construction projects such as building a small house, fixing city roads etc.
A common backhoe-loader. The backhoe is on the right, the bucket/blade on the left. Invented in Burlington, Iowa in 1957 the Backhoe loader (note: this needs checking – may have been invented in the UK by Joseph Cyril Bamford, founder of JCB) is probably the most common variation of the classic farm tractor. As the name implies, it has a loader assembly on the front and a backhoe on the back. When both the loader and the backhoe are permanently attached it is almost never called a tractor, not generally used for towing and usually does not have a PTO. When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments almost always have a separate seat on the attachment itself.
Backhoe-loaders are very common and can be used for a wide variety of tasks: construction, small demolitions, light transportation of building materials, powering building equipment, digging holes/excavating, breaking asphalt, and paving roads. The backhoe bucket can often be replaced with other tools such as a breaker for smashing concrete and rock. Some loader buckets have a retractable bottom, enabling it to empty its load more quickly and efficiently.
Retractable-bottom loader buckets are also often used for grading and scratching off sand. The front assembly may be a removable attachment or permanently mounted. Often the bucket can be replaced with other devices or tools. The backhoe loader must be equipped with a tool coupler in order to mount different attachments to the loader. A tool coupler consists of two hydraulic cylinders on the end of the loader arm assembly which can expand and retract allowing different tools to be attached to the unit.
Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs in areas too small for larger equipment. Their versatility and compact size makes them one of the most popular urban construction vehicles.
WHEEL LOADERS
Wheel Loader is a Front end loading machine. Wheel loader dig and as well as do secondary loading. Wheel loaders which do only secondary loading are called Pay Loaders.
The Wheel loaders are classified according to there bucket size and operating weight. The bucket size ranges from 1 cum upwards. The Wheel loaders can be tyre mounted or track mounted. The more popular version being tyres.
The Wheel loaders are very versatile and can be engaged in construction works, ranging from road work, plant loading, hopper and wagon feeding, stevedoring and mineface excavation.
A Wheel loader typically has semiautomatic or autometic transmition with autometic gear sifting. The power train will include engine, transmition, related propellar shaftes and powered axles at both front and rear.
A typical hydrolic curcuit for implimentation will include fixed/variable displacement pumps, controll valves, and actuators for boom, arm and bucket operation. Normally the steering curcuit is kept separate from the impliment curcuit.
The linkages are 2 types:
1- Paralallo bar and
2- Z bar
Autolevelling mechanism is also inbuilt in some of the loaders.
