What do you need to prepare for CNC Machining quotationWhen you need to order one type of Cnc Machining Parts, such as CNC Machining Aluminum Parts, you need product quotations from multiple suppliers and choose the best one to start your project. The decision may be influenced by CNC machining cost, delivery time, delivery time, and quality.
To ensure you get an accurate quote, manufacturing suppliers will need your information to ensure they can produce exactly the parts you expect and provide accurate estimates.
To ensure fast, reliable, and accurate price estimates for manufacturing partners when requesting a quote, here are a few things to prepare.
CNC processing
1. Design drawings
As a general offer, relevant documentation is essential. Used to identify clear requirements, such as product definitions, delivery requirements, etc. In CNC machining services, product design is the basis of CNC quotation. CNC machining parts usually have high precision and accuracy. To produce a final part with precise shape and dimensions, submit both 2D and 3D drawings.
2D engineering drawings can specify product dimensions (length, width, diameter), tolerances, surface texture and other features to be machined, 3D CAD design is mainly the need to establish a programming language (G-code) to guide the movement of CNC machine tools and operation tools. Even for projects that do not require CNC machining, such as vacuum casting, it is useful to use 3D CAD files to estimate raw material consumption and part weight.
General precision parts drawings: structural drawings, material selection, dimensions, process requirements (including heat treatment, surface treatment) Mechanical parts drawings with high precision requirements: In addition to the above, additional dimensional tolerances, shape and position tolerances, fits, special process requirements, etc. may be required
2. Material
The material of the CNC machined part is an important factor in determining the total cost. Many types of metals and plastics can be used to make rapid prototypes and production parts. They each have unique mechanical and physical properties that can help you achieve the performance you need. Material prices are not determined by CNC machining companies. There are many materials available for CNC machining manufacturing and Rapid Prototyping.
The choice of material depends on its mechanical properties, characteristics, processing technology and use. Tell us the characteristics you want to use or the performance of the product, we can provide you with a more accurate quotation, we can consider the use of material cost for related processing, so that the quotation is more accurate.
3. Quantity
Quantity or yield is also important. This will change the delivery time and total cost. As you know, prototype machining is suitable for the testing and development of individual parts. CNC machining is ideal for low/medium/high volume production. Documenting the number of parts required allows for clearer quotations and lead times. Different manufacturing processes are best suited for different numbers of parts. Therefore, it is better to know the quantity very well at the beginning of the quotation process.Fourth, the appearance of the product
The appearance of the part may not be specified in the CAD design, such as color, surface finish, and other text. Clear information can be documented with graphics and documents, but it is best to contact the supplier for subjective details. In order to get the most accurate product, some technical tools can be used. If you want to change the appearance or get a specific look, different processes or operations will leave different surface finishes on the outside of the part and put forward your requirements, including roughness, hue, etc.
The right color is very important for the success of product innovation. However, color can be subjective, so it is necessary to convey this information to the supplier in a clear way.
Color selection
Finish
Regardless of the manufacturing process used, the final surface finish is preserved on the part. However, this may not be the effect you want.
Therefore, whenever possible, it is best to refer to known surface finish standards, use gauges, or templates to specify the desired finish. If flatness is important for your application, specify a Ra value if known. If necessary, we can measure the texture and flatness of the samples you provide to us.
