Overview of cnc milling machining part processing

Metal milling technology is the way to conduct measures for the purpose of cutting metal workpieces in mechanical processing activities. Milling offers many benefits, with the continuous development of milling technology that they are much more convenient.

Metal cnc milling machining part now widely applies in our country and countries with a developed mechanical industry.

Although the milling accuracy is not high and the metal finished product has a not very shiny surface, it offers high productivity, large quantity production in a short time, thereby reducing labor and machine costs.

However, with the advent of CNC milling machines, the accuracy of milling has been greatly improved and the surface of the milling object is also relatively smooth and glossy. Metal milling currently divides into types such as forward milling and reverse milling; each method has different advantages and disadvantages. Read on to find out information about metal milling methods here.

What is the forward milling method?

The first cnc milling machining part is forward milling, forward milling is the act of cutting metal workpieces in which the reciprocating motion of the milling cutter and the part is in the same direction.

Forward milling methods are often common for finishing milling because they improve the surface roughness of the product and provide high productivity when milling with small residuals.

Advantages and disadvantages of forward metal milling method

The forward milling method is one of the two modern milling methods today, the advantages and disadvantages of the forward metal milling method are as follows:

Advantages of the forward metal milling method

– The cutter extends life and side by up to 50%, thereby reducing the cost of tool change.

– The cutting depth of the tool gradually reduces, so the roughness is easy to improve and no slippage occurs.

– When cutting, the heat generated is not much and decreases gradually after cutting.

– When performing milling, the cutting force is always on the workpiece, so it makes machining jigs easier and cheaper.

The cutting force is always on the part, so it is easier and cheaper to process the jigs

Disadvantages of forward cnc milling machining part

– The metal forward milling method is difficult to apply to metal parts with hard shells such as hot rolled steel…

– Forward milling will bring about good work efficiency when the milling machine has good decontamination and the table wedge is also tightened.

– Knife is easily chipped; milling machine life is low due to strong impact of cutting gas, cutting from thickness to thin.

What is the reverse milling method?

Besides forward milling, reverse cnc milling machining part is the remaining metal milling method. When reverse milling, the milling cutter and part will move in reverse, so they are mainly applied in rough milling.

This reverse milling method has a number of advantages and disadvantages when it comes to implementation, read on to explore the next section. Learn more about technology, equipment and tools in milling here.

Advantages and disadvantages of reverse cnc milling machining part

Advantages of reverse metal milling

– The reverse metal milling machine runs quieter due to less impact.

– Knives are less prone to chipping than forward milling by conducting cutting from thin to thick.

– High-yield roughing

– Popular application on old milling machines due to the removal of machine dirt.

Disadvantages of reverse metal milling

– Slippage occurs when the feed amount is small

– When cutting, the cutting force always tends to pull the metal workpiece up, so the clamping force is large.

– The metal workpiece may clamp and interfere with cutting.

Learn what is milling and turning?

Milling is a common method common by most mechanical workshops from small to large. All types of CNC milling machines are versatile are easy to apply to many methods as well as have very wide technological capabilities.

Milling is one of the types of cutting processing, which helps to cut and remove the excess on the workpiece. CNC milling machining part methods include forward milling and reverse milling.

Like milling, turning is a machining method for cutting workpieces using the same machining principles as milling. The main movement in turning is the circular motion of the workpiece, which in turn forms the cutting motion.

Nature of milling and turning machining methods

To see the difference between the two methods of milling and turning, you need to first understand their nature first.

Machining turning

As mentioned in the previous section, turning is a machining method for cutting metal workpieces that uses the rotation of the workpiece and the movement of the tool to create a cutting path. In turning, it will include the workpiece and the cutting tool (knife).

Milling machining

Milling processing is also a form of metal workpiece cutting. The milling method differs from turning in that the main movement is the rotary motion of the cutting tool, which is the tool. The other movement is the linear feed movement in the vertical, horizontal or vertical directions.

During milling, the workpiece clamps on the table while the tool moves in all directions.

Features of milling and turning machining methods

Although using cnc milling machining part machining principle, milling and turning will have different characteristics. The characteristics of each method are as follows:

Hopefully with the above information, readers have better understand the two methods of reverse and forward milling. Each method will have different advantages and disadvantages, apply to different milling cases.
