To guarantee that the holder 53 does not damage ceramic workpiece, the holder 53 uses bakelite material.
Emphasis refering to fig. 1, shown in Fig. 7, Fig. 8, in the grinding of grinding machine, the grinding machine includes the fixture application of the application Pedestal 10, from the vertical portion 20 that the pedestal 10 projects upwards, the mobile work platform 40 on the pedestal 10, be installed on institute State on vertical portion 20 and be located at the grinding wheel component 30 of 40 top of mobile work platform, the folder being placed in the mobile work platform 40 Tool 50 and control system (not shown).
The grinding wheel component 30 can realize the shifting of Z-direction on the vertical portion 20 under the control of the control system It is dynamic, diamond dust is coated on the grinding wheel of the grinding wheel component 30.The mobile work platform 40 structure in the form of slot, including inside groove 41 and positioned at 41 periphery of the inside groove enclosing portion 42 to prevent coolant liquid from splashing out, pore structure is equipped in the inside groove 41 can will Liquid drain enters in other containers.The mobile work platform 40 can realize movement in X, Y plane.The sand of the grinding wheel component 30 The width of wheel is less than the length of the ceramic workpiece 60.
After the ceramic workpiece 60 is fixed on the fixture 50, it is placed in the lower section of the grinding wheel component 30；The application's Grinding machine processing technology is as follows:
S1, initial networked control systems；
This step includes the position adjusted the mobile work platform 40 in X/Y plane, the grinding wheel component 30 in Z axis side To position, keep the grinding wheel of the grinding wheel component 30 and the machined surface 61 in the outermost ceramic workpiece 60 of X-direction mutual Contact, the initialization further includes setting various machined parameters；The grinding wheel component 30 has been determined in the position of Z-direction to institute The cutting output of machined surface 61 is stated, the mobile work platform 40 is grinding wheel component 30 to the processing in the change in location of Y direction The processing amount of feeding in face 61, the revolving speed of grinding wheel component 30 indicate the revolving speed of board, and the X-direction is that the grinding wheel component 30 is right The machining path of the machined surface 61.
S2, activation system, the grinding wheel along the x axis carry out the machined surface of several ceramic workpieces 60 from initial position First time grinding；
After S201, initialization, the grinding wheel component 30 has been set in the initialized location of Z axis according to cutting output, described The relative position of grinding wheel component 30 and the ceramic workpiece 60 is similarly determining, i.e., location A as shown in Figure 8, the mobile working Platform 40 is moved in the X-axis direction from the location A, make the grinding wheel of the grinding wheel component 30 in X-direction to the machined surface 61 in Y The partial region of axis direction carries out straight line grinding until the wheel grinding completes the last one ceramic workpiece 60；At this point, The grinding wheel is located relative to the second place of the initialized location；
S202, then, the control system by setting the amount of feeding adjust the mobile work platform 40 in Y direction Position changes the grinding wheel and the ceramic workpiece 60 in the machining area of Y direction, i.e. B location shown in Fig. 8；Complete feeding Afterwards, the mobile work platform 40 is straight to several progress of ceramic workpieces 60 grindings in X direction from the second place To initial position.
S203, step S202 is repeated until completing the region-wide grinding to the machined surface of the ceramic workpiece 60.
S3, change the grinding wheel component 30 in the cutting output of Z-direction, repeat step S2 again to the ceramic workpiece 60 Machined surface be ground again, until the sum of described cutting output is equal to predetermined grinding thichness.
It should be noted that the control system realizes X/Y plane internal coordinate by controlling the mobile work platform 40 Variation realizes the variation of Z axis coordinate, in the specific implementation process, the change of the coordinate by controlling the grinding wheel component 30 Change, can individually be completed by grinding wheel component 30, can also individually be completed by the mobile work platform 40, equally can be two Person any combination is completed.
It is obtained by constantly verifying, the grinding machine is processed the ceramic workpiece 60 using following parameter and can effectively be controlled The aggregation of stress in process and the deformation generated, but at the same time can be opposite the big water mill of extension process time, extend Time can control 0.05mm or so in 10min or so, flatness.The initialization of board revolving speed described in grinding machine parameter after improvement For 2000-2600rad/min, optimal is 2400rad/min；Cutting at one time amount is 0.005-0.05mm, and optimal is 0.01mm；Institute Stating the amount of feeding is 5-30mm, and optimal is 10mm.Subsequent sandblasting can be cancelled with annealing process to adjust later by making this adjustment Flatness improves processing quality so that improving production efficiency, reduces cost.
The following table 1 is to sample 10 to process respectively to same a collection of ceramic workpiece 60 with the application technique using traditional handicraft The flatness comparison data obtained afterwards:
Table 1
As it can be seen from table 1 can reach without carrying out sandblasting with annealing process after using the method for grinding of the application Be more good flatness.Cancel blasting craft, processing cost can be saved, shortens process time.Cancel annealing treating process, Increase idiosome toughness of material, shortens technique processing cost and process time.
The application is improved grinding parameter, is realized better flatness, can cancelled subsequent by many experiments Sandblasting, annealing operation, greatly reduce processing cost, improve processing efficiency.
It should also be noted that, the terms "include", "comprise" or its any other variant are intended to nonexcludability It include so that the process, method, commodity or the equipment that include a series of elements not only include those elements, but also to wrap Include other elements that are not explicitly listed, or further include for this process, method, commodity or equipment intrinsic want Element.In the absence of more restrictions, the element limited by sentence "including a ...", it is not excluded that including described want There is also other identical elements in the process, method of element, commodity or equipment.
