As shown in fig. 1 and 2, the present embodiment provides a lens template processing method, which includes the following steps:

s1: selecting a template 1 to be processed;

s2: a cutter on the machining center machines the template 1 at a preset position, and a machining hole 10 is formed in the template 1;

s3: measuring the machined hole 10 by using a measuring head on the machining center, and outputting a measuring result to a control center of the machining center;

s4: the control center analyzes the measurement result, judges whether the analysis result meets the standard, if the analysis result meets the standard, the template 1 is taken out, the processing is finished, otherwise, the next step is carried out;

s5: and the control center performs compensation processing on the template 1 according to the analysis result, and then returns to the step S3 until the analysis result reaches the standard.

Through the processing steps, the problems of low processing efficiency, time-consuming processing and one-step forming of the traditional coordinate grinding machine are solved.

Preferably, the stylus is an automatic infrared raney stylus.

Preferably, the machining center is a vertical three-axis machining center of a machine tool, a control system of the machining center adopts MAKINOPRO.6, and an X axis, a Y axis and a Z axis of the machining center are independently distributed, so that any two axes are not on the same plane in space, and the motions of the two axes are not influenced with each other, thereby improving the rigidity of the machining center and ensuring that the machining center has better stability in machining compared with a traditional milling machine; meanwhile, the driving mode adopts a linear motor to drive, so that the back clearance of the screw rod is avoided, and good position precision is achieved. Illustratively, the control system of the machining center controls the position coordinates of the tool on the X-axis, the Y-axis and the Z-axis according to the control program so that the tool machines the preset position of the template 1 to form the machining hole 10. In this embodiment, a plurality of machining holes 10 are formed in the template 1, and the plurality of machining holes 10 are annularly distributed. More preferably, a 0.0025mm HEIDEHAIN grating ruler and a BLUM high-precision laser type tool setting gauge are arranged on the processing center, and the grating ruler is used for detecting the coordinates of the tool and the template to observe and track the feeding error so as to play a role in compensating the motion error of the tool; the laser tool setting gauge shortens the tool adjusting time and improves the working efficiency.

In the embodiment, the template 1 to be processed is made of pre-hard plastic mold steel (NAK80), the hardness of the material is low, cutting is facilitated, and meanwhile, the material is long in strength and long in service life and is not easy to deform.

Further, step S2 specifically includes:

s21: the template 1 to be processed is sent to a processing center and is clamped and fixed by a clamp of the processing center;

s22: the machining center calls out corresponding cutters from the tool magazine, and the control system controls the cutters to move to preset coordinates and machines the template 1 to be machined.

The template 1 to be processed is clamped and fixed by a clamp, so that the influence of position deviation of the template in the processing process on the processing precision is avoided; then, a corresponding cutter is adjusted to machine the machining hole 10 on the template 1, and after multiple machining, a plurality of machining holes 10 are formed on the template.

Preferably, the clamp is an IMAO high-precision clamp with an adjustable flatness version. The position of the template 1 is accurately positioned, and the position accuracy of the template 1 is adjusted, so that the processing accuracy of the template 1 is ensured.

Preferably, the tool shank is a sintered high-precision MST tool shank, so that the tool bounce is controlled within 0.001mm, and the machining precision is ensured; the cutter adopts a Mitsubishi D8I hard alloy six-edge cutter, and the precision of the machining hole 10 is high.

Further, step S3 specifically includes:

s31: the machining center exchanges the measuring head out of the tool magazine and measures the machined hole 10, and the measured value comprises the hole diameter, the central coordinate position and the central coordinate offset position of the machined hole 10;

s32: and outputting the deviation value of the measured value and the preset standard value to a control system.

When a preset number of processing holes 10 are processed in the template 1, the tool is adjusted back to the tool magazine, the measuring head is adjusted out of the tool magazine, the measuring head measures the template 1 to obtain the aperture, the central coordinate position and the central coordinate offset position of each processing hole 10, then the deviation value is transmitted to the control system, the control system judges whether each processing hole 10 meets the standard or not, if one or more processing holes 10 do not meet the standard, compensation processing is carried out on the processing holes 10 which do not meet the standard, during supplement processing, the tool automatically skips the processing holes 10 which meet the standard, and finally all the processing holes 10 meet the standard.

Specifically, in step S3, the measuring head measures the machining hole 10, and the deviation value of the measured value from the preset standard value is output as the measurement result to the control center of the machining center. Illustratively, one machining hole 10 has a diameter of 1.000mm and a preset standard value of 1.002mm, and the deviation value is 0.002mm, which is outputted as a measurement result to a control center of the machining center. The measuring head measures each machining hole 10, records the deviation value of each machining hole 10, and outputs all the deviation values to the control center for processing, so that the machining precision of each machining hole 10 is guaranteed.

Further, in step S4, the control center compares the deviation value with a preset tolerance range, and if the deviation value is within the preset tolerance range, the analysis result meets the standard, otherwise, the analysis result does not meet the standard. Illustratively, the preset tolerance range is 0-0.002mm, and the control center compares the deviation value of each machining hole 10 with the preset tolerance range, for example, if the deviation value of one machining hole 10 is 0.001mm, the deviation value of the machining hole 10 falls within the preset tolerance range, and reaches the standard, and compensation machining is not needed; if the deviation value of one machining hole 10 is 0.005mm, the deviation value of the machining hole 10 exceeds the preset tolerance range, and does not reach the standard, alignment is needed for compensation machining, so that the machining hole finally reaches the standard. Through the steps, the machining precision of each machining hole 10 on the template can be accurately controlled.

Further, in step S5, the deviation value is supplemented to the control program of the control center, and the template 1 is precisely machined. When the deviation value is compensated into the control center, the aperture deviation value and the center coordinate position deviation value of the processing hole 10 are included, so that the center position of the processing hole 10 is adjusted to be located at the preset position of the template 1 when the processing hole 10 is compensated. And (3) measuring the deviation value again after the compensation processing is carried out on the processing holes 10 which do not reach the standard, if the deviation value does not reach the standard, continuing the compensation processing, namely repeating the processes of measurement-compensation processing-measurement until the measured deviation value is within the preset tolerance range, and stopping the processing on the processing holes 10, so that all the processing holes 10 reach the standard to obtain the processed template 1.

The embodiment also provides a lens template, and the lens template is manufactured by the lens template processing method. The lens template has high precision and short manufacturing procedure and time, thereby saving the manufacturing cost.
