How does a single crystal milling tool process brass?
A customer from Singapore asked us about the processing of brass parts.
He needed a single crystal milling tool to process a certain brass part or a certain brittle material in the watch.
After initial communication between our engineers and customers, we got the following information:
Roughness requirements: finishing to mirror surface
Processing material: Brass
The customer provided us with a drawing of his original single crystal tool:
According to this complex drawing provided by the customer, we made a three-dimensional product schematic diagram.
And made a more intuitive schematic diagram of the tool details:
After the drawing was completed, our engineers researched and analyzed the technical difficulties of this tool in production and processing:
1. This tool adopts a rake angle of minus 15, which is difficult to process and its adaptability to the customer's machine is unknown.
2. Due to the special processing angle, a lot of fixtures need to be matched, which will increase the cost of the first production,
3. According to the drawings, it is known that the cutting edge of this tool is not the usual two sides, but the relatively rare six sides
Based on the above information, the initial production time of this tool is long and the cost is high.
The production of this tool is very difficult. It is necessary to further adjust the details of the tool according to the shape of the workpiece to be processed by the customer. It is also necessary to know exactly which cutting edge to use for tool processing.
At present, our engineers are still communicating with customers about the adjustment of details.
During the communication between the engineer and the customer, the customer was also very interested in our More SuperHard production process, and asked us a few points:
First of all, it is about the production process. Is the production process laser cutting or manual polishing?
More SuperHard adopts the method of manual grinding.
Comparison of laser cutting and hand polishing
1. Speed and efficiency
Laser cutting is an automated and efficient processing method that can complete high-volume jobs quickly and accurately. However, the time and labor costs required for manual grinding are relatively high, and the production capacity is low.
2. Accuracy
Laser cutting is a high-precision processing technology that can achieve high-speed, high-efficiency, and high-precision cutting. And laser cutting will not produce errors due to human handling problems. Manual grinding has high requirements on the technical level of the operators, and the precision of the processed products is relatively unstable.
3. Cost
Laser-cutting equipment is expensive and requires professional technicians to operate and maintain, so the initial investment is relatively large. The cost of manual grinding is relatively low, requiring less equipment and labor costs, and is more suitable for small-scale, personalized, and handicraft processing.
4. Material suitability
Laser cutting is suitable for most materials such as metal, plastic, wood, paper, etc. Manual grinding is suitable for materials that are softer, thinner and have better surface regularity.
What is the welding process of More SuperHard?
More SuperHard adopts vacuum welding, which has better firmness than the sintering process.
Vacuum welding is a method for processing materials that involves heating two or more materials in a vacuum to melt and fuse them together. The vacuum environment can reduce the oxygen content and prevent the material from oxidizing, so it is possible to weld precious metals or other materials that are easily oxidized.
Advantages of vacuum welding:
1. High welding strength: The vacuum environment reduces the oxygen content, which can avoid oxidation so that those easily oxidized metals can be welded.
2. High quality: Because the material is heated in a vacuum environment, the gas content inside the material can be reduced, so the welding quality can be improved.
3. Tight welded joints: It can realize the production of high-quality, tight welded joints.
How does More SuperHard choose between CVD and MCD?
More SuperHard can produce both CVD and MCD single-crystal tools.
CVD tools are expensive to manufacture. If you only need to process mirror surfaces, MCD tools can fully meet customer needs.
In the processing of non-ferrous metals, the processing effect of CVD tools may be better.
More SuperHard provides the best solution to boost your production.
