What kinds of CNC milling machines do you have?
We have vertical CNC milling machines, horizontal CNC milling machines and multi-axis CNC milling machines. Vertical CNC milling machines are cost-effective and have a wide range of applications. Horizontal CNC milling machines are used to cut grooves and slots on products and are ideal for cutting gear workpieces. Multi-axis CNC milling machines are CNC milling machines that can operate on more than four axes and can manufacture more complex and precise parts.

What parts can be made by CNC milling?
CNC milling is suitable for processing parts with complex shapes, feature planes and irregular surfaces, such as grooves, gears, threads and special forming surfaces of molds.

What types of materials can be used for CNC milling?
CNC milling machines can process a variety of materials, including metals, plastics and composites. The most commonly used are metals such as brass, titanium, aluminum or steel, and plastics such as PVC, ABS, polycarbonate and polypropylene.

What is the maximum diameter of the turned parts you process?
Workpieces with a clamping diameter of no more than 260mm can be processed by CNC lathes.

What parts can be made by CNC turning?
CNC turning is suitable for processing parts with cylindrical or conical surfaces, such as shafts, bushings and sleeves.

What is the difference between CNC turning and CNC milling?
The main difference between CNC turning and CNC milling lies in the processing process. Turning operations are performed by fixing the cutting tool and rotating the workpiece and can be used for processing operations such as drilling, tapping and knurling. Milling operations are performed by fixing the workpiece and rotating the cutting tool to process planes, grooves, gears, helical surfaces and various curved surfaces.

When should I choose 5-axis CNC machining?
5-axis machining can provide higher accuracy, precision, efficiency and reliability for processing more complex or finer parts. Therefore, when you need to produce complex parts with strict tolerances, choose 5-axis machining.

What is the maximum part size for 5-axis CNC machining?
The maximum size of our 5-axis CNC machined parts is 1050 * 900 * 600.

How accurate is wire cutting processing?
Our wire cutting processing tolerance is as low as ±0.0004 (0.01mm).

What shapes can wire cutting create?
Wire cutting is mainly used to process workpieces with various complex shapes and high precision, such as punches, dies, punch and die sets, fixing plates, stripper plates, forming tools, templates, fine holes and slots, narrow slits, arbitrary curves, etc.

What are the main limitations of wire cutting EDM?
Wire cutting processing requires that the processing material must be conductive and cannot process non-metallic conductive materials. Moreover, the efficiency is low and the cutting size is limited, which affects mass production.

What is the tolerance of manufactured parts?
The tolerance range of sheet metal processing parts is ±0.2 – 0.3mm.

What is the K-factor in sheet metal?
The K-factor is the ratio of the thickness (t) of the neutral layer position of the sheet metal to the overall thickness (T) of the sheet metal part material, that is: K = t/T. Standard calculation method: material thickness (t) * 1.66.

What is the cost of sheet metal processing?
The cost of a sheet metal manufacturing project depends on design, process, materials and processing.

What materials can you cut?
Our laser cutting process is suitable for a variety of materials, including aluminum, steel, stainless steel, copper, titanium and many other metal materials, as well as plastics and other non-metals.

How long does it take to cut materials by laser cutting?
This is usually determined by the size and thickness of the material.

What bending technologies do you provide?
We provide a wide range of metal bending technologies, such as V-bending, U-bending, step bending, roll bending and rotary bending.

What materials can be used for metal bending technology?
Some common materials for metal bending include steel, stainless steel, titanium, aluminum and copper.

When do I need rapid prototyping?
Rapid prototyping is usually used in two main scenarios. First, when you need to test a product or evaluate product risks, rapid prototyping is the best choice. Second, rapid prototyping is cheaper than prototyping, so when the product development cost is too high, you can also choose rapid prototyping.

What is the rapid delivery cycle of rapid prototyping?
It depends on materials, design complexity, etc.

What is the difference between rapid prototyping and 3D printing?
Quick prototyping is a new technology based on material accumulation method, which integrates mechanical engineering, CAD, reverse engineering technology, layered manufacturing technology, numerical control technology, material science, laser technology, etc. In fact, 3D printing is a technology for developing products by using additive manufacturing technology. It is only a branch of quick prototyping and can only represent a part of quick prototyping processing technology.

Which metal is best for die casting?
The main metals commonly used in die casting are zinc, copper, aluminum, magnesium alloys, etc.

What are the steps of die casting process?
Whether it is hot chamber die casting or cold chamber die casting, the standard process involves injecting molten metal into the mold under high pressure. The following are the steps in the complex die casting process:
Step 1: Clamping. Before this, the mold needs to be cleaned to remove any contaminants and lubricated for better injection and removal of the cured product. After that, the mold is clamped and closed with high pressure.
Step 2: Injection. The metal to be injected is melted and poured into the sintering chamber. Then the metal is injected into the mold under high pressure generated by the hydraulic system.
Step 3: Cooling. The solidified material will have a shape similar to the mold design.
Step 4: Ejection. After the mold is loosened, the ejection mechanism pushes the solid casting out of the mold. Ensure proper solidification before ejecting the final product.
Step 5: Decoration. It involves removing excess metal from the completed gate and runner. Trimming dies, saws or other procedures can be used for trimming.

Will die cast metal rust?
The main component of die castings is not iron, but materials such as zinc, copper, aluminum and magnesium, which makes the parts corrosion-resistant and not easy to rust. However, if the parts are stored improperly for a long time, they may rust.
