The roller burnishing process affects performance analysis of bearing bush

Bearing bush(red copper is the main material), the energy consumption is obviously reduced in the working process of press. Energy consumption represents motion resistance, which can be represented by the coefficient of friction. The friction coefficient in general physics is defined as the ratio of sliding resistance to contact pressure when two objects in contact produce sliding.

From the perspective of effect: 1) after rolling, the surface can easily get the mirror effect. 2) ordinary grinding generally cannot achieve the effect of mirror. 3) the workpiece surface has the effect of cold hardening after rolling. Be careful with brittle materials and less rigid workpieces. 4) improper selection of grinding parameters may cause burns on the surface of the workpiece.   From the perspective of technology: 1) the material of the rolled piece is simply matched with the...

How to use RBT roller burnishing tool roller burnishing process

Buy Roller Burnishing Tool The principle of rolling process is simply to extrude the surface of the workpiece with hard objects and to smooth the ripples left by the cutting process on the workpiece surface. And the internal main component of the cast iron workpiece's material is graphite (powder), plus a part of iron and other metals. As for the precision of roller pressure, roller burnishing tools is used to adjust the size of the tool by manually screwing the...

How to use RBT roller burnishing tool roller burnishing process

A deep hole is a hole whose length proportion is greater than 10 to the diameter of the hole. In most cases, the depth ratio of L/d is greater than 100. Such as cylinder hole, axial shaft oiled hole, hollow main shaft hole and hydraulic valve hole, etc. The machining precision and surface quality of these holes are high. Moreover, some processed materials have poor cutting performance, which is often a major problem of production. However, as long as we...

FIG. 1 The clamping diagram of roller burnishing tools

Selection of process parameters   Magnitude of interference Magnitude of interference quantity size determines the size of the rolling pressure, fluid rolling pressure increases with increasing as the magnitude of interference. Magnitude of interference quantity should not only consider the selected by the uneven plastic deformation of the surface of the workpiece, but also want to consider the change of cylinder diameter size. If the roughness is to be reduced, can be selected with a smaller value, not exceeding the...

What factors should be considered in the process of roller burnishing tool?

With the development of economy, roller burnishing tool has become an indispensable rolling tool in our production and life. The appearance of this tool provides convenience for people's production and life. But what problems do we need to pay attention to when using roller burnishing tools? Many people don't know much about this, and we'll give you a brief introduction. I hope our introduction will help you. First of all, the surface roughness after processing is also affected by the...

Processing technical of Inside Diameters(Holes) Roller Burnishing

The principle of inner hole rolling technique is the same as that of external rolling pressure. Because of the high productivity of roller burnishing process, honing is often replaced by rolling process. After the inner hole rolling pressure, the accuracy is within 0.01mm, and the surface roughness Ra is 0.16m or more. Rolling processing is very sensitive to the density, soft and hard uniformity of materials, and the uneven quality of materials can seriously affect the rolling quality. The rolling...

Burnishing, roller burnishing tool, The method of burnishing, burnishing the surface, burnishing process, burnishing tool

Burnishing refers to the use of mechanical, chemical or electrochemical functions to enable the workpiece to obtain a bright and smooth surface processing method. The workpiece is machined by a soft wheel with polishing paste to reduce the roughness of the workpiece surface and improve its brightness. The soft wheel is made of leather, felt, canvas and other materials, with certain elasticity. The burnishing paste is made from abrasive and grease (including stearic acid, oil, kerosene, etc.). When polishing, the...

Roller burnishing process of workpiece surface

Roller burnishing processing is the burnishing tool on the workpiece surface, and moving along the workpiece surface, make the surface produces cold plastic deformation and the deformation strengthening, to have a bright and clean surface machining method, as shown in picture. When machining, a number of cylindrical rollers (including roller outer edges) are configured outside the tool. The diameter of the roller burnishing tool should be slightly larger than the diameter of the workpiece. When the tool is rotated, the...

Roller burnishing processing is a process of finishing and strengthening the surface of mechanical parts.   Application on a lathe   The burnishing tool rolls relative to the surface of the workpiece, exerting certain pressure to produce plastic deformation on the surface of the metal, modifying the surface hardness, abrasion resistance and fatigue strength of the workpiece surface. The surface roughness value of the workpiece that is rolled and processed can reach Ra = 0.8 ~ 0.4mm in an instant....
