An Overview of Hand and Machine Tools

Machine tools are used for managing inflexible materials, generally by cutting, boring, grinding, shearing, or other forms of deformation. It is a power-driven metal cutting machine that changes the shape and size of the material.

A machine is a mechanical device that uses power to apply forces or to control movement to perform an action Drills, Saws, Power Sanders, Nail Guns, Power Ratchet Sets, Lathes, Air Compressor, Air Tools, etc.

Whereas on the other side hand tools require human force rather than machines. They have been used by humans since the Stone Age for various purposes.

The list includes Hammers, Pliers, Ladders, Wrenches, Clamps, measuring tools, tool belts, axes, chisels, cutters, files, striking tools, screwdrivers, snips, hammered tools, drills, knives, etc.

Various tools and their usage

Be it hand tools or machines, they have been serving distinct purposes for ages. Let’s learn about various ways and forms.

Jewelry-making tools Handmade jewelry is jewelry that has been also assembled and designed by hand rather than the use of machines.

Jewelry-making tools like beading pliers, hammers, anvils, torches, sizing gauges, soldering machines, welders, magnifiers, and any other tools that assist jewelry making.

CNC – Computer Numerical Control: It is used to control digitized data, to control data, automate, and monitor the movements of a machine. Most common usage includes milling, lathe, routers, welder, grinder, laser or waterjet cutter, sheet metal stamping machines, robot. A CNC controller works together with a series of motors to move and control the machine axes and execute the programmed signals.

A lathe is a machine tool that rotates a piece of work on its axis to perform some operations such as cutting, knurling, drilling, deformation, facing, sanding, and turning. The Lathe can also be used for woodturning, metalworking, metal spinning, thermal spraying, glass-working and can be used to shape pottery, and are controlled by computers are called CNC lathes.

Machining cutting tools range from rough cutting equipment, like chop saw or grinder, production-oriented machines, Lathe, Drill Press, Milling machines, Welders, Handheld Rotary Tools. Milling or grinding machine tools are like a lathe, that is used for cutting, shaping, and finishing materials these tools use belts, chains, hubs, couplings, pulleys, sprockets, bushings, bearings, linear actuators, slide rails, bevel gears, worm gears, etc.

Honing is a finishing process used to settle the alignment of features such as holes or bores, and produce a better-finished surface, the stones called honing stones are built with a rough scuffle held together with cement. Surface finishing is a wide range of industrial processes where, finishing process recovers its appearance, adhesion, solderability, tarnish resistance, corrosion resistance, chemical resistance, wear resistance, hardness, electrical conductivity, and control the surface roughness or also repairs it. An unfinished surface is often called mill finishing.

Surface finishing processes can be categorized as:

1. Removing or reshaping the finishing.

2. Adding or altering finishing.

Horticulture is a study that evaluates flowers, fruits, vegetables, spices, and medicinal & aromatic crops. It is divided into several categories which focus on the cultivation and growing process of different types of plants and food items for specific purposes.

Due to the advancement of science and technology, the use of metals like copper, steel, and iron has the growth of various kinds of garden tool and equipment like hand cultivator, tractor, spray pump, lawn mower, harrow, spade, secateurs, fork, sprinkler, rake, pruning saw, grass shear, budding, etc. Garden tools are like: Hand Trowel, Secateurs, Secateurs, Gardening Gloves, Spade, Fork, Shovel, Rake, Saw, Wheelbarrow hammer, etc.

What are pneumatic and hydraulic tools?

Pneumatics and Hydraulics are applications of liquefied power. They both use a pump, to control the valves, and use liquid to transmit mechanical energy.

Pneumatic systems are normally powered by compressed air, while hydraulics uses relatively incompressible liquid such as hydraulic or mineral oil, ethylene glycol, water, or high-temperature fire-resistant fluids.

Pneumatic systems are selected above hydraulic systems because of the lower cost, flexibility, and higher safety levels of the system they include systems like Air compressors, Vacuum pumps, Air brakes used in buses, trucks, and trains Compressed-air used in engines and vehicles, HVAC control systems used in Nail guns, Precision drills used by dentists, switch and pump,

Pneumatic Tools: - Impact Wrenches, Die Grinder, Angle Grinder, FRL, Air Hammer.

Hydraulic Tools: - band saws, cut-off saws, power hacksaws, reciprocating saws, chain saws, long-reach chain saws, Hydraulic torque wrenches, impact wrenches, rotary impact hammer drills, nut runners, reaction arms, reaction pads, torque wrench links.

The wrench hammer is not designed to be a hammer but it is designed to be struck with a hammer as the head is wrapped around a nut-bolt, that is too tight to remove with a normal wrench hammer which is also known as a striking wrench.

Getting to know fundamentals of Coupling

A coupling is a device used to connect two tubes to transmit power. The purpose of couplings is to join two pieces of spinning while permitting some degree of misalignment.

Types of coupling

Jaw Couplings.

1. Sleeve Coupling.

2. Tire Coupling.

3. Disc Coupling

4. Diaphragm Coupling

5. Gear Couplings

Roller Chain Coupling.

Working with needle and thread is known as sewing and Knitting is a method by which it is worked to create a textile or a fabric.

Knitting Machine:

1. Warp Knitting Machine.

2. Single Circular Knitting Machine.

3. Double Jersey Circular Knitting Machine.

4. Single Needle Straight Bar Knitting Machine.

A woodworking machine is a machine that is planned to process wood. They are usually powered by electric motors and are used widely for woodworking. Sometimes grinding machines used for grinding small pieces and are considered as a part of woodworking machinery
