A few days ago, a fan left a message in the background.

Analysis
SO-SO-SO-SALLED DEEP-HOL treatment is more than 8 times the opening report (there is no prescribed standard), and we call it a deep hole. For example, the diameter is 5 mm, the depth is 40 mm, the pore diameter ratio = depth / diameter, 40 mm / 5 mm = 8 times, the pore diameter of 2.4 mm in the problem, The depth is 115 mm; MM = 47.9 mm, this depth is really a shallow oh.
Let’s talk about material problems. The materials given in the problem are steel and sometimes cast iron parts. When you pose a problem, I personally think that the number of materials and the specific hardness must be given.
Because the range of steel parts is not very specific, after all, there are too many steel parts, including steel with low carbon content, medium-carbon steel, etc.; , which will be difficult.
Therefore, it is necessary to describe the mark and the hardness of the material to be expected in advance.

Then, we said that the tools of the tool are mentioned in the article that friends factories use high -speed steel exercises. The high -level steel materials drill is generally treated by tingling during treatment.
Obviously, this method is very effective, but do not forget the characteristics of high -level steel exercises.
The size mentioned above, these high-speed steel exercises, the general interior prices will be at less than 100 yuan without taxes, and this specification of the Japanese system will be between 150 and 200 yuan without taxes.
Let’s talk about the equipment.

Solution
In fact, when the cost of accounting, general accounting methods should be similar. .
In fact, there is a logical problem, I don’t know if you considered it. After all, the knife is a product.
The added value of the parts itself is too low. Formula, but several times we choose a knife to us.
It has been mentioned above that domestic knives are considered to solve this problem. Non -chopped tools face the delivery period, and they can generally be delivered in 2 to 3 weeks.
However, the size of the text is indeed a little embarrassed.
Some factories must receive orders to receive orders. (The figure below is the standard product with a diameter of 40 times a certain brand, but it does not meet the requirements, so this size must be a non-standard product. If the budget is sufficient, you can try to personalize no – standard products)
This is also calculated in the cost of the manufacturing cost. The stability of the consistency of high -level steel tools is also a problem.
Finally, the total cost of the evaluation, the new stab + repair, now I write the proportion of workshop costs for your reference.
The tools represent 3% of the total cost
The machining time represents 30% of the total cost
Stopping time represents 7% of the total cost
The cooling solution represents 16% of the total cost
The replacement of the tool represents 25% of the total cost
Other total costs of 19% of the total cost
