Machines are important and they play a vital role in helping you complete your woodworks or metal working tasks. Using machine can help get your jobs done quickly, accurately and efficiently with little or no stress. Machine tools are beneficial, they aid you to meet your daily target with enhancing your bulk wood and metal process.
What is a Machine?
According to mechanical engineers, “machine” is regarded a group of well-arranged mechanism that is interconnected to perform specific operations. Machines will only work if they are utilizing any form of power: electrical, mechanical, hydraulic, or pneumatic power.
A machine is always designed with various mechanism. The numbers of these mechanisms differ with respect to the purpose of the machine. Some machines come with mechanism ranging from few to few hundreds. Also, not only the number of mechanisms that differs but also the size: some machines are smaller, while others are larger.
What Is a Machine Tool?
Machine tools have a quite different and restricted concept. It usually talks about field regarding metal-working or machining. They make significant contributions to our daily life making it more convenient. They make use of different techniques in the fabrications process. Each machine tool provides you with 2 or more specific operation: for cutting metals – can make use a laser (looking for the best desktop laser engraver ?) or jets of high-pressure water.
From the definition, we can further show the characteristics of these machines.
- Machines tools must be power driven unlike machines which are operated by humans
- It must be large in size.
- It must possess high values: capability and performance.
- It must be able to perform more than a single operation.It should be able to shear off excess material on the workpiece using a cutting tool.
For a machine to earn the name “machine tool” it must meet the four criteria discussed above. To be precise, any machine that meets up with the above condition should be called a machine tool.
Common example of machine tools
Presently, there exist different types of machine tools: manually / electrically powered or manually or automated operated. But with advancement in technology, many machine tools are now operated electronically.
- Lathe machine tool,
- Milling machine tool,
- Shaping machine tool,
- Industrial drilling tool,
- Industrial boring tool, etc.
Is lathe a machine tool?
According to how a machine is defined and can be recognized, any lathe machine is right to be called a Machine. Moreover, this is different when your field is metal working or machining, it is usually more appropriate to address the lathe machine as a machine tool rather than just machine.
The word “machine tool” isn’t just any word or name, it has a real significance to a metal worker. And, both center lathe and CNC lathe also should be equally regarded as a machine tool. A lot of people associated with the metal-working field love to categorize the lathe as a machine tool because it provides high capability.
In a nutshell, lathes should not be regarded as a machine but a machine tool.
Different Kinds of Machine Shop Tools
As of now, there is a different kind of machine tools available in the market.
Milling machine – they exist in two types: CNC and manual milling machines. Both perform the same function – out of any type of metals and materials, you can use this machine to produces various type of gears, surfaces, etc. when it comes to machining, milling machine performs efficiently – drilling and cutting metals to the customized size, shape, and dimension. It’s usually mistaken for lathe machine, lathe machine as its workpiece moved until the desired shape or cut is achieved.

Grinding Machine – this machine is named according to its function – grinding. The machine adopts a method, where its abrasive wheel serves as the cutting tool. They are usually needed at the end of an industrial operation. They perform a task such as polishing, cleaning, casting, buffing surfaces, and also getting your cutting tools sharped. Its grinding abrasive wheel performs these task on the workpiece by making each abrasive particles act as small, tiny cutting tools which cut off undesired chips off from the work piece.
Shaping Machine – this machine is quite popular in the metal-working manufacturing industries. It has the ability to cut curves, angles, any shape from the work piece. These machines exist in different types to suit any of your purposes. You can work with them if you require some wood or metal shaping.
Drilling Machine – one of the popular types of the milling machine is drills. They are simply used to drill holes or openings. Drill tool (drill bits) only move in a rotational motion. The drill bits are easily clamped using manual or automatic methods. Drills can be used to cut thread also. The speed of movement, rotation, and type of drill bit used to depend on the depth you desire and the material of the workpiece.
Lathe Machine – this machine mostly works on an object that are symmetrical objects – spheres, cones or cylinders. These work pieces are placed on a spindle, rotated while having either a grinding or carving tool pressed on it to give the desired shape. CNC lathes were first released into the industrial market in 1952. You can make use of the lathe machine to produce parts with ferrous and non-ferrous metals, plastics, or wood.
Broaching Machine – uses its toothed tool called broach for its machining. Linear and rotary are the two main types of broaching machining, with the linear broach as the more common type. Broaching machine has high precision especially when the work piece has an odd shape. In broaching, there are three main sections: roughing, semi-finishing and finishing.
Other Machine Tools
Aside from the above tools, there are other machine tools – threading machines, saws, drilling presses and gear shapers. In case, you need any of job done with a machine tool you can always find them in any reputable shop.
These shops will provide you with threading tools, turning tools, boring tools, wear pads, trepan tools, and recessing and grooving tools.
