Because the surface roughness of the processing workpiece is related to the size of the abrasive particle size, it has no obvious relationship with the size of the pores. In addition to the grinding roller screws, the atmospheric sand wheels can also be used to grind the trapezoidal scion, thermal material (such as magnetic steel, tungsten silver alloy), thin -walled parts and easy deformation workpieces, soft metals (such as aluminum (such as aluminum (such as aluminum (such as aluminum (such as aluminum (such as aluminum (such as aluminum ) Hard alloy, radio ceramic component raw blanks, and metal materials that are difficult to processed by general sand wheels. It is also suitable for processing rubber products (such as butadyl gyrus rollers for textile industry, printing rollers for printing), non -metal soft materials such as plastic products, and products such as hard minerals (such as marble).
Compared with the trapezoidal screw, the roller screw is different due to the different structural forms and parameters. For example, the roller of the roller screw is arc -shaped, and the size of the coordinating sideline with the diameter DO in the center of the drum is the size of The type is trapezoidal, and in the middle diameter D. , D. In order to assess the size of the screw -side coordination, it has its particularity in terms of grinding methods and the adjustment of the machine tool.
Rolling bead screw grinding cold rolling processing
1. Sand wheel trimming
The accuracy requirements of the eccentric distance E of the roller arc radius R and double arcs of the roller screw are generally 0.01mm. In order to ensure that the screw roller rolled after the roller screw is equipped with the connection of the rolling ball heart and the connection of the roller in the section surface and the vertical line of the thread axis. It is particularly important to correct the grinding roller screw correctly in order to achieve accurate roller -type and thin surface roughness and reasonable production efficiency.
2. Sand wheel selection
The spiral trail of the roller screw is a single arc or double arc. The contact area of the workpiece during grinding is large, and the relatively large -grinding heat is also large. Taking atmospheric sand wheels as ZUI.
(1) The air pores are the pores that are easily volatile when the rals, binding agents and stomachs are added according to the raw mill, binding agent and stomaton formula during the milling of the mill, such as crickets, coke, etc., and the pores formed after roasting.
The micro -pilot pine tissue sand wheel is another variety of the air -pores wheel. Its stomatical size is smaller than that of the air pores, which is generally about 0 or 5ram, but the pores of the sand wheel are even more uniform than the air pores wheel.
