模具的定期磨光保证了一致的冲压质量。定期打磨模具，不仅可以提高模具的使用寿命，而且可以提高机床的使用寿命。那么打磨模具时应考虑哪些因素呢？

The regular polishing of the die ensures the consistent stamping quality. Grinding the mold regularly can not only improve the service life of the mold, but also improve the service life of the machine tool. So what factors should be considered when grinding the mold?

（1）在R01-025毫米的情况下，切削刃圆角的锐度取决于切削刃的锐度。

(1) In the case of r01-025 mm, the sharpness of the cutting edge fillet depends on the sharpness of the cutting edge.

（2）砂轮表面应清理干净。

(2) The surface of grinding wheel shall be cleaned.

（3）建议使用松软的粗粒砂轮。如WA46KV

(3) It is recommended to use a soft coarse-grained grinding wheel. Such as wa46kv

（4）每次研磨量（刀具）不应超过0013mm。过度磨削会导致模具表面过热，相当于退火处理，模具变软，大大降低模具寿命。

(4) The grinding amount (tool) per time should not exceed 0013mm. Excessive grinding will lead to overheating of the die surface, which is equivalent to annealing treatment, making the die soft and greatly reducing the life of the die.

（5）打磨时须添加足够的冷却液。

(5) Add enough coolant during grinding.

（6）打磨时，冲头和下模应固定牢固，并使用专用工装夹具。

(6) During grinding, the punch and lower die shall be firmly fixed, and special tooling fixtures shall be used.

（7）模具的研磨量是恒定的。如果达到此值，冲头将被报废。如果继续使用，很容易损坏模具和机器。

(7) The grinding amount of the mold is constant. If this value is reached, the punch will be discarded. If you continue to use, it is easy to damage the mold and machine.

（8）济南注塑加工厂家提醒您，打磨后，应使用磨刀石处理边缘，以去除过度锋利的边缘。

(8) Jinan injection molding manufacturer reminds you that after grinding, the edge should be treated with a grindstone to remove the excessively sharp edge.

（9）磨尖后，清洗、退磁、上油。

(9) After sharpening, clean, demagnetize and oil.

注意：有很多方法可以磨快模具，这可以通过一个特殊的磨刀器或在平面磨床上实现。冲头和下模的刃磨频率一般为4:1。磨刀后请调整模具高度。

Note: there are many ways to sharpen the mold, which can be achieved by a special knife grinder or on a surface grinder. The grinding frequency of punch and lower die is generally 4:1. Please adjust the mold height after sharpening.

（1）不正确的锐化方法的危害：不正确的锐化会加剧模具刀刃的快速损坏，导致每次锐化的锤击次数大大减少。

(1) Harm of incorrect sharpening method: incorrect sharpening will aggravate the rapid damage of the die blade, resulting in a significant reduction in the number of hammers per sharpening.

（2）正确的刃磨方法的好处：定期对模具进行刃磨，可使冲孔质量和精度保持稳定。模具的刀刃损坏缓慢，使用寿命较长。

(2) Benefits of correct grinding method: regular grinding of the die can stabilize the punching quality and accuracy. The blade of the die is damaged slowly and has a long service life.
