How the Chamfering & Deburring Tool works?

Chamfering & Deburring Tool is designed and developed to solve the Chamfering work that traditional cutting Tools cannot complete. In mechanical manufacturing, the traditional Chamfering & Deburring Tool, Chamfering & Deburring Tools, Chamfering and Deburring Tools Manufacturer, Chamfering and Deburring Tools Supplier, Chamfering Tools, Deburring Toolstool can not complete the Chamfering & Deburring work for double-sided cylinder inside and outside hole wall, all kinds of valve body hole wall. But RBT Chamfering & Deburring Tools are fully qualified.

3 types of tools for different bore diameters.

Introduction to product structure: the Chamfering & Deburring Tool consists of arbor assembly, adapter assembly, blade (single and double blade) and tension spring assembly. The front end of Chamfering & Deburring Tools is the inlet guide body, the front end of the blade is 45°, the inner end is 33°, and the groove mouth is 6°.

How it works: when arbor body of Chamfering & Deburring Tool enters the hole, the cutting edge of the blade relies on the elastic strength of the tool bar to chamfering and deburring the hole. After the completion of the hole, then enter the opposite end of the hole for chamfering and deburring. The diameter of the blade is changed by elastic shrinkage.

The outer circumference of the blade is processed by chamfering, so it will not cut or damage the original hole wall. Chamfering & Deburring Tool opens naturally after the hole is drilled for Chamfering cutting. When the tool body penetrates into the lower end of the hole wall, no matter it is opened or closed, the corresponding chamfer cutting will be generated. In particular, when returning the tool, the blade is closed, and the 33° Angle of the inner end is changed into approximately 45° Angle, which can reach 45° of chamfering Angle.

id blind roller burnishing

Can roller burnishing tool be used to process thin-walled parts?

Q: Can roller burnishing tool be used to process thin-walled parts?

A: Burnishing rolling process is used to press the surface of the workpiece.

Therefore, in order to withstand the treatment pressure, the treated part needs to have enough wall thickness (20% of the inner diameter). Thin – walled parts will be deformed or damaged after processing.

id blind roller burnishing

This problem is usually solved by the following methods:

  1. Reduce roll pressure allowance.
  2. Use pliers to support the outside of the workpiece.
  3. The rolling pressure is arranged in the first step (before forming the thin-walled workpiece).

According to the parameters of the workpiece, a special auxiliary tool for thin-walled parts should be designed.

What’s the effect of roller burnishing process on workpiece performance?

What's the effect of rolling process of workpiece performance?

What’s the effect of rolling process of workpiece performance?

 

Surface quality of roller burnishing tool‘s rolling process has the following effects on workpiece performance:

①The effect on wear resistance

The surface roughness has a great influence on the initial wear of friction pairs. But not the less roughness, the more wear-resistant. Under certain working conditions, there is an optimal parameter value of the surface of friction pair , which is about 0.32 ~ 1.25 m.

 

②Effects of fatigue strength

Under the action of alternating to load, the surface roughness and defect from workpiece are easy to cause stress concentration and fatigue crack damage. For some important parts that bear alternating loads, such as the junction of crankshaft crank and shaft neck, roller burnishing should be carried out to reduce the surface roughness and improve the fatigue strength.

 

③Effects of corrosion resistance

The rougher the surface of the workpiece, the easier it is to accumulate corrosive substances. The deeper the valley, the effects of the infiltration and corrosion are the stronger. Therefore, to reduce the surface roughness of the parts, it can improve the corrosion properties of the parts.

 

④Effects of parts’ quality

The rough surface of parts will increase the gap of parts after wear and tear, change the nature of parts, reduce the precision and rigidity of parts, and affect the stability and reliability of operation. Therefore, the surface roughness parameter value of the workpiece with the required parts must be limited.

For example, roller burnishing tools for processing hydraulic cylinder and cylinder hole should meet the following requirements:

 

  1. For processing workpieces with 2-4 precision, the surface finish of the hole should be 9 ~ 10;
  2. Rolling parts and supporting parts shall have high mechanical strength and hardness (H R C= 58);
  3. The roller burnishing tool can be kept stable after adjusting the tool according to the diameter of the workpiece;
  4. The workpiece can be returned freely after the completion of the workpiece processing, the workpiece with a length of 50-10mm after the trial processing also can be returned freely;
  5. Simple structure, good technology, and easy to replace roller burnishing tool’s parts (rollers and support cones).
