Metal milling: important details of technology
The popularity of machining CNC processing on milling machines is enviable stability. There is a simple explanation for this: milling allows you to use different processing methods and get the part without defects and defects.

Machining CNC

Professional multifunctional machines are important equipment in the machine park of many enterprises. Besides, milling can be horizontal, vertical, with an inclination at a certain angle. It all depends on the method of mounting the cutter, the cutting tool, which rotates in the feed direction of the machine and removes the metal layer by layer.

Types of milling works in machining CNC

There is a classification of milling in machining CNC. Not only on a way of fastening of a mill, but also on its direction, and on movement of preparation. The aspects involved are:

  1. Firstly, accompanying milling easily removes chips without premature wear of the tool
  2. Second, it is not necessary to install clamping mechanisms on the machine
  3. Moreover, hence and the level of roughness meets the requirements
  4. Not only it is best for counter milling "against giving" is carried out for roughing
  5. But also, is suitable even for the hardest alloys
  6. Also, when removing chips, the metal is deformed, its surface is strengthened in machining CNC
  7. And, make cuts, grooves, windows, or grooves, use end milling
  8. Face processing of metal on the milling machine is necessary for work with dimensional preparations
  9. Lastly, profile details are milled by a shaped method

How to ensure the best performance of machining CNC

One of the main factors in obtaining a properly treated surface is the use of a quality cutter. In addition, the tool is selected according to the type of metal, the method of milling, the purpose of the future part. Furthermore, for example, an end mill is required to work with high-speed feed in the machining CNC

The disc tool is needed for chamfering, metal sampling, workpiece trimming or groove cutting. Moreover, for metal milling services to be of high quality and become a reason for positive feedback, it is equally important to perform all operations on high-quality equipment.

Machines preferred for machining CNC

 

Japanese machines Mazak and Mori Seiki with CNC ensure compliance of the finished part with official standards and accurately embody the drawings of customers. More importantly, the result of professional milling is to obtain a part with high fatigue strength, quality surface cleanliness.

Production of stainless-steel shafts

Shafts are cylindrical parts, that are an essential part of machining CNC. These are common to transmit torque in industrial equipment, in transport and other mechanisms where there is rotation. Shafts differ in size, weight, material and shape.

Classification of shafts in machining CNC

  1. First, depending on their geometric axis, the shafts are straight, flexible, and cranked (eccentric)
  2. Second, there are smooth, hollow, and stepped shafts in shape
  3. Third, shafts happen with the channel on an axis (hollow) and cast
  4. Also, they are made of strongest steel grades because these parts must withstand heavy loads
  5. Above all, to improve the performance, the shafts are subjected to heat treatment

Areas of application of stainless-steel shafts

Shafts are important parts of machines and mechanisms (machining CNC). Without them it is difficult to imagine the work of any industrial equipment. Moreover, shafts are needed wherever there is rotation (in rotating mechanisms and in transport). Here you can order shafts from stainless steel grades under any technical tasks.

Stages of shaft production in machining CNC

Stainless steel shafts can be made according to the state standard, and according to individual drawings and models. Stages of shaft production are:

1.First, design and construction.

2.Second, facing and boring of workpieces on a CNC lathe.

  1. Third, milling grooves and grooves.
  2. Moreover, finishing grinding.
  3. Also, dynamic balancing.

6.Lastly, applying a protective coating in the processes of machining CNC

Composition of shafts in machining CNC

Shafts, which are designed for use in aggressive environments, are made of corrosion-resistant steel grades. Furthermore, the first stage of production of shafts is turning of preparations on CNC lathes and precision drill rods thanks to what products of even big diameters outside and inside are easily processed.

Then, depending on the type of shaft, welding of its individual elements can be performed. After milling the grooves, the shaft is ground, which ensures dimensional accuracy. Apart from this, measurement of shaft sizes is performed by modern methods using a laser in the procedure of machining CNC.

How to do shaft balancing in machining CNC?

At this stage of production, the quality of shafts is checked by a method of dynamic balancing. After all, if the shaft is made even with a small defect, then the energy transfer will be large losses, and the equipment will fail.

Application of a protective coating and heat treatment of shafts

If the shaft will be operated in an aggressive environment (for example, it will be exposed to acids, alkalis, and salts), the product is subjected to additional corrosion protection in the form of electroplating. And to increase the strength and durability of the shafts are subjected to heat treatment.

Categories of steels that you can go for in machining CNC

In our center of precision processing for machining CNC, you can order shafts from stainless steel of brands:

  1. Firstly, AISI 304. Steel is acid-resistant and in the short term can withstand a sharp rise in temperature up to 700 degrees Celsius.
  2. Secondly, AISI 316. Steel is resistant to corrosion, aggressive environments and high temperatures due to the presence of molybdenum (2.5%).
  3. AISI 321. Steel contains a lot of nickel and almost 1% titanium, is heat-resistant and heat-resistant (suitable for operating conditions 600-800 ° C).
  4. 08Х13. Steel is corrosion-resistant and heat-resistant, suitable for operation at temperatures up to +580 ° C.
  5. Above all, 12Х18Н10. Chrome-nickel steel, corrosion-resistant structural can also be common for machining CNC

How is production defined in this era of advancements?

Based on the Japanese automotive industry, lean manufacturing has made a name for itself and revolutionized manufacturing around the world. Furthermore, this method of production can effectively optimize production at your plant by minimizing waste and reducing production time.

Pros and Cons of machining CNC

Before implementing lean manufacturing at your manufacturing facility, you need to analyze the advantages and disadvantages of the systems of machining CNC

Machining CNC 2021Advantages of Lean production:

  • First and foremost; waste minimization.
  • Second, most significant advantage of the system is that economical production
  • Also, CNC can effectively minimize waste at the production facility.
  • Because companies use large amounts of inventory and waste,
  • This process eliminates obsolete inventories.
  • Apart from reducing CNC waste, machining CNCalso reduces the cost of the operation.
