The Different Tools Used in Metal Working

Metal is one of the most valuable and essential commodities on earth. While the way it is shaped or processed differs from one technique to another, the tools utilized in metal working are mostly the same, whether they’re for creating ornaments, structures, or objects.

The Different Tools Used in Metal Working

Milling Machines – This is used for obtaining more complex shapes with metals and similar materials. Milling machines differ in the following characteristics: shape, shank, flutes or teeth, coating and finishing, helix angle, and lastly, center cutting.

Drills – This is a common tool not only used in metal working but also with other materials needing holes to be drilled in them. There are different types of drills one can use in metal working. Some are hand-powered, such as the bow drill, brace and bit, gimlet, and pin-chuck, a small drill most often used by jewelry makers.

A hammer drill, on the other hand, is a combination of the usual electric drill and hammer, both of which we see carpenters and DIY homeowners commonly utilize. In most cases, the hammering feature may be switched off. A rotary hammer drill works similarly but only better.

Wireless drills operate by battery power. They usually offer the same functions with standard electrical units. A drill press can be mounted or attached to the floor or any other structure. People prefer drill presses over handheld drills because they facilitate the drilling process, secure the material being drilled in one place, and improve the accuracy of drilling. Geared head drills and radial arm drills function like drill presses, only better. Lastly, there’s the mill drill, which is considered a lightweight alternative to a milling machine.

Taps and Dies – Screw threads in metalwork are created with the help of taps and dies. A die is used for cutting the male part of a screw thread, such as bolts, while a tap is used for cutting the female half like nuts.

There are several kinds of taps used today in metal working. A bottoming tap is used for blind holes and never unthreaded ones due to the absence of taper in its edges. A plug tap is, on the other hand, used for untapped holes, improving alignment. Lastly, a taper tap is utilized for materials that are difficult to tap such as alloy steel. There also different kinds of dies used today. They may or may not have adjusting crews and made up of one or two pieces.

Grinding Machines – These are used for making extremely fine finishes or light cuts on hard materials like metal. Different types of grinding machines are used today. A belt grinder uses coated abrasives to help in processing metals. A jig grinder is used for grinding pins and holes and continuing the work that a mill’s started but unable to finish. A bench grinder utilizes two wheels to accomplish roughing and finishing while a cylindrical grinder utilizes various wheels. A tool and cutter grinder produces specialized grinding functions while a surface grinder utilizes magnets in its operation.

Metal Lathe – These were originally invented to remove layers from metals but were gradually used for processing other materials as well. Again, there are various kinds of metal lathes used today. Center lathes are simple to operate and mostly used by hobbyists and others with non-professional interest in metal work. A capstan lathe offers greater functions and better accuracy. A turret lathe, on the other hand, offers similar features found in a capstan lathe and more, like boring, reaming, and drilling.

A multispindle lathe is also known as a screw machine. It can be used for both turned and milled objects. A combination lathe can both serve as a milling machine and a drill. They are, however, designed generally for home use as their performance fall short from complying with the safety standards set by industrial projects. A CNC lathe is like a multispindle lathe, only better. Lastly, a Swiss style lathe is also known as a Swiss turning center and used when extremely high precision of desired.

Using a Toolmakers Microscope to Evaluate Metal Working
All the tools previously discussed cannot completely guarantee perfect craftsmanship and that’s when you’d need a toolmakers microscope. By magnifying images of the various parts and angles of your metal object, you’ll be able to discern even the smallest flaws and rectify them immediately.

If you don’t have a toolmakers microscope yet, consider purchasing one with an inverted frame so that it can accommodate even the larger-sized samples. A portable digital toolmakers microscope would also be helpful, allowing you to study samples that can’t be placed on the stage.
