Technique, if it is not, the then corresponding alarm of display；
Step 2, dress workpiece 6, start grinding program；
Step 3 judges whether to repair grinding wheel 22, cut if it is not, grinding wheel 22 carries out corase grinding to workpiece 6, if so, grinding wheel 22 is repaired in starting
Program；
Step 4 continues half fine ginding, starts process of measurement, calculates machining allowance；
Step 5, starting finishing procedures, carry out finishing grinding；
Step 6, the final process of measurement of starting, if size qualification, into next step；If dimension overproof has a margin, count again
Mill amount is calculated, 5 are thened follow the steps, if prompting product size overproof without surplus；
Step 7 judges whether end face has ground, if so, grinding is completed, dismantles workpiece 6, if it is not, then reciprocal by magnetic force
Workbench 41 rotates angle, and the corase grinding executed in step 3 is cut.
Control method of the invention uses five axis control systems, integrates modern numerical control control and automatic measurement,
Revolutionary innovation is carried out to the traditional diamond-making technique on ceramic mold core periphery, this grinding machine devises special Grinding Software, uses
Human-computer dialogue operation interface, there is 6 schematic diagram of workpiece and variable mark on interface, and operator is only permitted to make variable simple defeated
Enter to produce mold core processing and process of measurement, it is easy to operate to examine, it is low to operator's skill requirement, convenient for management, by this
Control method realizes the high-power end face for being directly ground mold core both sides, and precision is high, and finish is good, while past by rotation magnetic force
Multiple workbench 41 is ground to adjust the other both ends of the surface of workpiece 6, does not need clamping again, solves multiple clamping and cause manually
The problem that amount is big and dust is big, substantially improves the environment of production work, high degree of automation.
Further, it is additionally provided with step 3.1, the step 3.1 is set between the step 3 and step 4, described
Step 3.1 is to judge whether 22 service life of grinding wheel finishes, if so, prompting with changing grinding wheel 22, if it is not, carrying out repairing grinding wheel 22.
By judging whether 22 service life of grinding wheel finishes, if so, grinding wheel 22 can be re-replaced, in order to avoid generate can not be ground or
Person directly results in the problem of Grinding Machining Quality difference, if it is not, be judge 22 surface of grinding wheel and corner angle whether rounding rust,
If rounding rust can carry out swing finishing to grinding wheel 22 back and forth by dresser 5, so that the whole circumference of grinding wheel 22 can
It is trimmed to modify and finish；Through the above steps, the working efficiency and quality of mold core workpiece 6 can be improved, building ring is improved
Flying upward for dust is reduced in border.
Double-ended grinding machine of the invention uses five axis control systems, realize Double End automatic grinding, automatic compensation and
Automatic measurement can expeditiously complete mold core periphery Roughing and fine machining and automatic measurement, greatly to ceramic mold core in clamped one time
Big to improve production efficiency, finish precision is high, this grinding machine process and its measurement are by numerical control program whole-process control, to ceramic die
The traditional diamond-making technique on core periphery has carried out revolutionary innovation, is 3-5 times of traditional processing efficiency, and processing cost is tradition side
The 1/3 of method, process and measurement are not need manual intervention by numerical control program whole-process control, improve working environment, just
In production management, the control method of the double-ended grinding machine realizes the high-power end face for being directly ground four side of mold core, in configuration machine
The measurement accuracy of line measurement is high, according to data analyze it is automatic carry out grinding, efficiently precisely, high degree of automation, reduce at
This.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
