What is CNC polishing, and how to polish?

Polishing refers to the processing method that makes the surface roughness of the workpiece reduced by mechanical, chemical or electrochemical actions to obtain a bright and smooth surface. It is the use of polishing tools and abrasive particles or other polishing media on the surface of the workpiece modified processing.

How to polish?

  1. Mechanical polishing

Mechanical polishing is a method of polishing a smooth surface by cutting or plastic deformation of the material surface to remove the convex part after being polished. Mechanical polishing generally USES the whetstone bar, wool wheel, sandpaper, and so on, mainly manual operation. Special parts, such as the surface of the rotary body, can be used by the turntable and other auxiliary tools. The workpiece with high surface quality may adopt the method of super fine grinding and polishing. Ultra-fine grinding and polishing is a special grinding tool. In the grinding and polishing liquid containing abrasive materials, it is pressed on the surface of the workpiece being processed for high-speed rotational motion. Surface roughness of Ra0.008μm can be achieved by using this technology. This method is the highest of all polishing methods. This method is often used in optical lens mould.

 

  1. Chemical polishing

Chemical polishing is to make the surface of the material in the chemical medium surface protruding part than the concave part of the first dissolution, so that smooth surface. The main advantage of this method is that it does not require complex equipment and can polish the workpieces with complex shapes, and many workpieces can be polished at the same time. It works efficiently. The key problem of chemical polishing is the preparation of polishing liquid. The surface roughness obtained by chemical polishing is generally 10μm.

 

  1. Electrolytic polishing

The basic principle of electrolytic polishing is the same as chemical polishing, that is, the surface of the selectively dissolved material is slightly protruding to make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.

The electrochemical polishing process is divided into two steps:

(1) macro leveling

The solution diffuses into the electrolyte, the surface of the material decreases geometrically, Ra>1μm.

(2) slightly smooth

Anode polarization, increased surface brightness, Ra<1μm.

 

  1. Ultrasonic polishing

The workpiece is put into the abrasive suspension and put together in the ultrasonic field, and the abrasive is ground and polished on the surface of the workpiece by the ultrasonic oscillation. The macroscopic force of ultrasonic machining is small, which will not cause deformation of workpiece. Ultrasonic machining can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution to separate the dissolved product on the surface of the workpiece, and the corrosion or electrolyte near the surface is even.

  1. Fluid polishing

Fluid polishing depends on the high-speed flow of the liquid and its carrying abrasive particles to flush the surface of the workpiece to achieve the purpose of polishing. Common methods are: abrasive jet machining, liquid jet machining, fluid power grinding, etc.

 

  1. Magnetic grinding and polishing

Magnetic grinding and polishing is to use magnetic abrasive under the action of magnetic field to form abrasive brush, grinding the workpiece. This method has high efficiency, good quality and easy control of processing conditions. With suitable abrasive, the surface roughness can reach Ra0.1μm.

What are the characteristics of Flat Surface Roller Burnishing Tools?

Roller Burnishing Tool is a very important tool of the mechanical industry. There are many different roller burnishing tools on the market, which are prepared for different mechanical devices. Flat Surface Roller Burnishing Tool has been widely applied to recent years. Before using Flat Surface Roller Burnishing Tools, we should first understand the characteristics of Flat Surface Roller Burnishing Tools.

Features of Flat Surface Roller Burnishing Tools

(1) the surface roughness of the preceding procedure is not greater than 5μm, the surface before rolling should be clean, and the allowance of diameter is 0.02-0.03mm. With Flat Surface Roller Burnishing Tools, a single fine pressure can reduce the Surface roughness of the product from around Ra6.3um to between ra0.2-0.05μm, and only cast iron is between ra0.4-0.2μm.

(2) the precision of shape and the precision of mutual position of the workpiece after rolling mainly depends on the precision of shape position of the preceding procedure.

(3) generally, the rolled object is only suitable for plastic materials, and the material structure is required to be uniform. When the machined surface is rolled, its wear resistance is improved and its fatigue strength is increased by 30%. Flat Surface Roller Burnishing Tools can improve the tightness and eliminate the early wear, so that it has the advantages that cannot be obtained in machining.

(4) with mechanical fine tuning device, the deviation control is within 0.0025mm and the adjustment range of each is 0.5mm. High productivity, wide range of processing technology, not only can be used to process the outer round surface, for the inner hole, end surface processing can be used.

What is a deep hole?

In most cases, L/d is greater than or equal to 100.

Such as cylinder bore, shaft axial oil hole, hollow main shaft hole and hydraulic valve hole and so on. Some of these holes require high machining accuracy and surface quality, and some of the processed materials have poor machinability.

As we all know, for burnishing large diameter and deep hole, there are some difficulties in following:

  • If the cutter body is long, also there is high requirement for radial runout of clamping tool.
  • For cooling system, there is an inner-cooling device in the tool, so there are high requirements for equipment.
  • High requirement for equipment rigidity
  • Chip removal difficult

Problems that should be paid attention to when roller burnishing tool is used for deep hole processing.

Process dosage during rolling: Vc=20 ~ 100m/min, f=0.2 ~ 0.5mm/r, and rolling surplus is 0.05 ~ 0.15mm. Lubricant is mechanical oil.

Pay attention to the problem: the workpiece must be cleaned before rolling; Interference should be flexibly mastered, that is, the workpiece material has high hardness, thin wall, low original surface roughness, and its interference is smaller. The opposite is bigger.

Above all, RBT recommend deep hole blind hole roller burnishing tool, which the picture of real product in following:
