What are the technical requirements for machining shaft parts?

 The mechanical processing technology requirements for shaft components include several aspects. Shafts are common and vital parts in machines, supporting transmission components and transferring torque. The technical requirements for shaft components, which are related to large-scale machining, generally cover the following aspects:

1. Diameter accuracy, geometric precision:

Diameter accuracy ranges from IT5 to IT9, crucial for supporting and matching shaft necks. Geometric precision should be within the diameter tolerance range, typically stricter than diameter accuracy. Radial runout is typically 0.01-0.03mm for standard precision shafts and 0.001-0.005mm for high precision shafts. Special requirements should be clearly specified.

2. Surface roughness:

Due to factors like machine tool precision and operating speeds, surface roughness requirements vary. For surfaces supporting shaft necks, roughness should be 0.16-0.63um, while for mating surfaces, it ranges from 0.63-2.5um.

 

3. Main shaft materials, blanks, and heat treatment:

Common materials for shafts include 45 steel, treated through processes like normalizing, annealing, quenching, tempering, and induction hardening to achieve specific strength, hardness, wear resistance, and toughness. Powder electrostatic spraying enhances aesthetics and durability. Alloy structural steels are preferred for high-speed shafts, improving wear resistance and fatigue resistance post heat treatment. For main shaft blanks, forged parts and round bars are used to minimize machining and enhance mechanical properties.

It is widely known that many products developed by companies require the use of aluminum components. Meeting product development requirements inevitably involves the use of aluminum components, thus selecting a reliable CNC aluminum parts manufacturer is crucial.

How does a CNC machining center ensure precision for mass-produced products?

Precision is one of the most important indicators to evaluate the processing performance of a CNC machining center . The processing precision and processing errors have a great impact on the quality of the processed parts. How can a CNC machining center ensure the precision of mass-produced products? The most commonly used processing method in the CNC machining industry is the trial cutting method. The trial cutting method is to try cutting, measure the size, adjust the cutting depth of the tool, cut again, and repeat the process until the required size is achieved. This method can ensure that the error is within a reasonable control range, but it is quite cumbersome and has a low production efficiency. It is mainly used for single-piece and small batch production. In mass automated production, CNC machining centers can achieve the required size by adjusting the relative positions of the machine tool, fixture, workpiece, and cutting tool in advance, thus achieving the goal of ensuring

How to deal with the plastic injection molding raw material is not filled?

图片
Electric injection molding machine in the production of injection mold will encounter the situation of injection molding is not filled, there is a lack of glue at the bone position right Angle and fuse connection, here to share some experience. Analysis of glue injection is not filled: 1. The trapped air in the bone position makes the injection molding machine fill up. 2. The filling of the injection molding machine caused by the glue welding line is not filled. Reason analysis of glue injection is not filled: When the injection molding machine is working, the mold gluing method is two-point gluing, and the injection speed is too fast, which is easy to cause the gas trapped at the right Angle of the bone position and cause the filling dissatisfaction; If the injection speed is too slow, it is easy to fill the fuse at the end of the flow. The solution: Multistage injection molding and position switching. In the first stage, the medium speed filling channel was used to pass

Control of Injection Molding Parts Processing Temperature

图片
There are many kinds of plastic, many plastic materials melting time are different, because the plastic does not have a specific melting point, the so-called melting point is a melting state of the temperature segment, the structure and composition of the plastic molecular chain is different, so the impact on its fluidity is also different, then in the production of injection parts manufacturers in the injection parts processing temperature control is also very important. 1. Mold temperature Some plastic materials due to high crystallization temperature, slow crystallization speed, need higher mold temperature, some due to control size and deformation, or the need for demoulding, to higher temperature or lower temperature, such as PC generally requires more than 60 degrees, and PPS in order to achieve a better appearance and improve fluidity, mold temperature sometimes needs more than 160 degrees, Therefore, the mold temperature has an inestimable effect on improving the appearanc
