What is metalworking by cutting? This method role?

Every metal product goes through a process called metalworking by cutting to achieve the given requirements. Here, this article will introduce you to metalworking methods by cutting.

What is metalworking by cutting?

Metalworking by cutting is a process where we cut a layer of metal on the surface of the workpiece to create a part with the exact shape and size as required on the drawing.

This cutting process is done on specialized machine tools, it can also be done by hand with other common tools. About 70%-80% of the work in mechanical production is used to process all kinds of machine parts, the final stage of mechanical processing.

The role of metalworking by cutting method Metalworking by

Metal cutting is the processing method after the billeting method. It is an indispensable method to improve dimensional and shape accuracy. When choosing the right processing method, the surface quality of the parts will be guaranteed, especially the details with high precision requirements, when the product meets the requirements, it will increase the economic value of the products. there.

Commonly used

metalworking machining methods Metal turning method in metalworking by cutting

In this method, the main movement is the rotation of the workpiece.

The feed motion will belong to the reciprocating motion.

Turning method commonly used for machining round parts

Metal turning method

Milling method in metalworking by cutting

The main motion of this method is circular motion The feed

motion of this method is the reciprocating motion of the workpiece.

Milling is often used to machine complex flat and curved parts.

Drilling method in metalworking by cutting A

tool used for cutting the circular and reciprocating movements of the shaft. The drill can make a hole from its solid workpiece and expand that existing hole or thread the hole.

Grinding method in metalworking by cutting

The main movement of this method is the rotation of the grinding wheel, while the feed movement is the translational motion of the workpiece and the grinding wheel. The rotation speed of the grinding wheel is very large, the processing residue is small, and accordingly, the number of cutting edges in the cutting tool is large, so the part after grinding has a very high gloss, often used in finishing machining.

Planing and striping

This is a metalworking and cutting method, using the main movement of translation, planing in the horizontal direction, and slanting in the vertical direction. Products that need to be used this method are usually flat or grooved types.

Broaching method

This is one of the methods of metalworking by cutting, in which the main motion and feed motion are the reciprocating motion of the cutting tool while the workpiece is clamped. The main products are special shaped hole products, the shape of the holes is decided according to the shape of the broach.

Why use oil in metalworking?

The oil used for metal cutting is Metalworking fluid, also known as Cutting fluid. This is a liquid used in metalworking to cool and lubricate the metal being machined. At the same time, it also has the effect of cleaning metal debris that appears during machining from the surface of the part. One can also call cutting oil as cutting fluid.

Using oil in metal cutting

Oil used in metalworking includes two main types:

Unmixed oil:

This is oils do not need to add solvents when used. They are often used in machining stages that generate little heat or require good lubrication to achieve the desired effect.

Mixed oil:

This is the type of oil that when you want to use it, you have to add more. When machining at stages where high heat generation is required but low lubrication is required. The blending ratio can be changed to suit the machined object.

Cutting oils are used to:

• Have a cooling effect on the worksite To be worked on.
• Have a lubricating effect to protect the blade.
• Have the effect of cleaning metal chips

When using cutting oils can cool and lubricate machining points, wash away cutting chips, helping to reduce machining errors.

Recently, it is very common to use the lubrication method with a very small amount of oil, to minimize the impact on the environment.

CNC machine

• oils Slideway oils: lubricating guides, slides and spindles
• Grease #2: belt lubrication
• Metalworking oils (water or non-aqueous): Cools and lubricates the tool cutting and cutting
• parts Hydraulic oil: For hydraulic chucks and CNC machine gearboxes

Thus, we have provided you with information about metalworking by cutting, thereby understanding the process. operations as well as commonly used methods.
