What Details Should The Prototype Manufacturer Pay Attention To? Shenzhen Shouban Model Factory

1. The inner hole processing method of the prototype manufacturer

There are many methods to process the inner hole of the prototype model, such as drilling, reaming, reaming, mirror hole, grinding hole, drawing hole, grinding hole, moving grinding hole, rolling hole, etc. Here are two common methods of drilling and reaming. For drilling, due to the long length of the twist drill, the small core diameter and poor rigidity, and the influence of the chisel edge, the drilling has the following technological characteristics:

1. The drill is easy to shake;

2. The aperture is easy to expand;

3. The surface quality of the hole is poor;

4. Large axial force when drilling

Compared with the twist drill, the structure of the reaming drill has the following characteristics:

1. Good rigidity; due to the small amount of back-grabbing of the reaming hole and less chips, the chip pocket of the reaming drill is shallow and narrow, and the drill core diameter is larger, which increases the rigidity of the working part of the reaming drill.

2. Good guidance; the reaming drill has 3-4 cutter teeth, the number of edges around the cutter increases, and the guiding effect is relatively enhanced.

3. The chip condition is better; the reamer has no chisel edge to participate in the cutting, and the cutting is brisk, and the larger feed rate can be used, the productivity is higher, at the same time, the chip is less, the chip removal is smooth, and the processed surface is not easily scratched.

Therefore, compared with drilling, reaming has higher machining accuracy, lower surface roughness value, and can correct the axis error of drilling to a certain extent, and the machine tool suitable for reaming is the same as drilling.

2. What details should the prototype manufacturer pay attention to?

   The current CNC prototype model manufacturers need to pay attention to the details. The first step is to find out the defects, shortcomings, and shortcomings in the design of the product and the reality. The most direct and effective way is to improve the bad places. , Do a small amount of production, and finally mass production. Therefore, the importance and accuracy of model making directly determines whether the specifications of mass-produced products meet the design requirements. What are the matters that need to be paid attention to in the process of CNC prototype model making?

1. Conventional product prototypes are generally made of ABS material. This material is easy to process and the post-processing of the prototype is also more beautiful.

2. Prototype for high temperature resistant products, optional materials

(1) Epoxy resin;

(2) Bakelite;

(3) Black PC;

(4) PA (nylon).

Except for the black PC which can be bonded to the hand boards made of these four materials, the other three types cannot be bonded and need to be processed integrally.

3. Abrasion resistance product prototype, can choose POM or PA. Prototypes made of these two materials cannot be bonded and need to be processed as a whole.

4. High-toughness product prototype, can choose PA or PP. Prototypes made of these two materials cannot be bonded and need to be processed as a whole.

5. Transparent product prototypes, can choose PMMA (acrylic), transparent ABS, transparent PC and other materials. Prototypes made of these materials have been polished with extremely high transparency, achieving the same effect as real products.

6. The surface treatment of the product prototype is generally divided into surface effects such as oil spraying, electroplating, frosting, silk printing, and pad printing. Prototype spray oil is divided into smooth surface, matte surface, sand surface, transparent color, translucent color, fluorescent color, rubber oil and other effects.
