How to choose the robot shaft parts material?

The blank is the most initial state of a part,but Parts are formed by the blank according to various technical requirements after a variety of processing.The blank choice is not only affects the blank manufacturing technology and the cost of enterprise, but also has close relationship with the machining technology and quality of parts.Therefore, it needs the close cooperation of technicians in both the manufacturing and mechanical processing to reasonably determine the blank material, structural shape and size .

Ⅰ. Requirements to be met in material selection
Mechanical products are composed of a number of parts, ensure the use of parts is to ensure the use of the product requirements.Therefore, the blank selection must first meet the parts performance requirements.

1) Structural shape and size requirements
Due to the different functions of mechanical parts, their structural shapes and sizes are often very different, and various blank manufacturing methods have different adaptability to the structural shapes and sizes of parts.Therefore, when selecting the blank, the structural shape and size characteristics of the parts should be carefully analyzed.Select suitable blank manufacturing method.

Six key heat treatment technology problems in bearing manufacture

If the improper heat treatment, bearing heat treatment is the core of the bearing manufacturer, one of the key technology of heat treatment process and the physical properties of raw materials determines the bearing the final hardness, uniformity of hardness, abrasion resistance and contact fatigue life.What problems will arise?

Heat treatment deformation
Bearing parts in heat treatment, there is the thermal stress and organization stress, the internal stress can overlay or partially offset each other, is complex and changeable, because it can as the heating temperature, heating rate, cooling, cooling speed, parts of the change of the shape and size changes, so the heat treatment deformation is inevitable. Understanding and mastering the change rule of bearing parts can make the deformation of bearing parts (such as the ellipse of the ring, the size increase, etc.) in a controllable range, which is conducive to the production. Of course, mechanical collision during heat treatment will also cause deformation of parts, but such deformation can be reduced and avoided by improved operation.
