Summary of Mechanical Processing Procedures and Price Estimation

1,Mechanical processing procedures:

1) Cutting: Use a sawing machine to cut the corresponding material into the approximate size of the parts that need to be processed. (Usually leave a margin of 5-8 mm in length and width)

2) Cutting difficile: Use lathes, milling machines, wire cutting and other equipment to process the approximate shape of the parts required by the drawing, removing most of the blank allowance.

3) Timeliness: Timeliness in naturam temporalitatem et artificiam temporalitatem divisa est. Natural aging refers to allowing the workpiece to stand for 24 hours or longer, while artificial aging refers to heat treatment of the workpiece in a high-temperature box or box furnace. The purpose of time efficiency is to eliminate stress and reduce deformation of the workpiece during precision milling process.

4) Dimensiones mensurae: Postquam processus senectionis consummatis est, factus est laboris aliquid gradus deformation is et mensus est ut determinaret reliquum mensuram.

5) Precision machining: Strictly follow the dimensions required by the drawing to carry out precision machining to meet the workpiece dimensions required by the drawing. For workpieces with high precision requirements, semi precision machining processes will be arranged as needed before precision machining.

6) Post processionem: Haec processus in priorem processum insertabitur secundum diversas sortes parterum.

1. Fitter: including chiseling, sawing, filing, straightening, drilling, threading, deburring, chamfering, and screwing of works.

2. Machina gravitationis: Quando alta precision est pro circulo exterior, intrinsecus caudam, finem faciem, etc. opus est relinquere marjinam post proceduram machinitatis precision is et machinam gravitationis ad grindum.

3. Maquina Boring: For holes with high requirements for size, shape, and positional accuracy, use a boring machine for machining.

4. Flaw detection: Surface flaw detection is required for standard screw parts and welded parts to ensure the strength of the workpiece.

7) Surface treatment: After the processing of the workpiece is completed, surface treatments such as ordinary oxidation, pulse anodizing, hard oxidation, passivation, sandblasting, painting, etc. need to be applied to the workpiece surface to achieve the effect of aesthetic and oxidation prevention.

8) Inspection: It is necessary to inspect the surface treated workpiece, including various dimensions, colors and other key information, to ensure compliance with the drawing requirements.

9) Packaging and storage: Packaging the qualified workpieces and storing them together with certificates of conformity, inspection reports and other documents.

2,Composition of quotation for machined workpieces

1) Materials: Calculate material costs based on the density and price of materials required for different workpieces. (ρ=m/v)

2) Horae opus: prima horas operation is manus et horas operationis, pretium calculatur based on personnel hourly wages and equipment hourly fees multiplied by program running time. (Programmatio)

3) Pecunia operationis superficiis: Calculate the price based on the different surface treatment processes required by the workpiece drawing.

4) Profit: Based on the company's operation and scale, calculate the profit quotation proportionally on the aforementioned price basis.

5) Tax: Calculate taxas based on the invoicing format and tax points required by the country.

6) Transportatio: Corresponding fees will be charged based on different transportation methods. (Exemplis freight air, logistics, express delivery, etc.)

3,Processus labor hours

Time required to complete a process, process hours=preparation hours+basic time

Tempus preparationis referit ad tempus consumptum a laboribus ad cognoscere se cum documentis procedentibus, vacuum colligere, fixturas installare, instrumentis machinae adjustare, nullis positiones alignere et fixturas disassemabiles.

Tempus principalis est tempus quam opus est procedere programmam procedentis.

4,Quotation cost estimation method (this method is applicable to mass-produced products for reference)

Processing cost=(material cost+processing fee) * 1.2~1.5 (including management fee, sample and small batch factors * 3~5)

Material cost=weight (density * volume) * unit price (yuan/kg)

Processing fee=process hours * unit price (yuan/hour)
