The history of precision machining

Precision machining is the process by which a product is processed and measured to incredibly accurate standards. For something to be accurate, it has to be the right dimensions, satisfactory limits, tolerances and quotas. How precise an object can be will depend on the specific purpose of the objects mentioned – for some things a much more precise type and cut will be necessary than for others.

Initially, rather than using automated machines, small parts as well as larger items would be made by skilled craftsmen, which meant that almost any type of production was incredibly labor intensive as well as very costly.

As the industry has changed significantly, there are now far fewer people who need to do the physical work, and instead there is a need for skilled engineers to maintain the machines as well as programmers to enter the information so the machines can operate fully. This means that why the work has become of a higher quality, the cost is reduced, why you will see incredibly complex machines are much cheaper than it could have been before.

As technology has evolved, this has become more and more accurate, to the point where in fact most parts are far more accurate than they really need. Typically, these rotated parts are manufactured by large-scale precision machining using automatic machining, computer numerically controlled lathes or rotary transfer machines.

With a large and eclectic range of products and parts that can be produced using this method, there is almost no end to the possibilities. Both large and small items we use every day have been manufactured using precision machining and all sorts of different materials and results can be obtained. It is possible for a machine to produce all the various components needed for a single object, for example, although more often each machine is set to perform an individual task.

Look around. Everything that is produced and not manufactured by hand is more likely than not made by precision machining. Given the way this technology has evolved over the last hundred years, we can only imagine what kind of development there will be in this industry in the coming years. Soon we can see workshops run by a single maintenance engineer, with all programming done through CAM.
