5 axis CNC machining parts

Generally, there are two types of five-axis machining centers: 3+2 and simultaneous five-axis. A 3+2 five-axis machining center consists of three linear axes (X, Y, Z) and two rotational axes (A, B). On the other hand, simultaneous five-axis refers to the capability of all five axes (X, Y, Z, A, B) to move simultaneously in a coordinated manner.

3+2 machining primarily relies on the rotation of two axes on the worktable, allowing the tool to perform multi-sided machining along the rotating surfaces of the product.

Five-axis machining centers are equipped with two additional rotational axes, allowing the worktable to rotate simultaneously. As a result, both the tool and the worktable can rotate at the same time, enabling the machining of different surfaces of complex workpieces.

It also utilizes computer-controlled tool movements along five different axes, enabling extremely precise cutting and machining in three-dimensional space.

Typically, the applications of five-axis machining include components such asimplantable medical devices, surgical robots, surgical instruments, turbocharger impeller machining, secondary impeller machining, 7-stage impeller machining for turbo molecular pumps, high-pressure water pump impeller machining, air compressor impeller machining, blower impeller machining and diesel engine crankshafts.

Different axes:The tool of the three-axis machining center can move along three directions, which is what we call the three axes (X,Y,Z).This means that the workpiece often needs to be repositioned and re-clamped multiple times to complete complex machining processes. Four-axis machining adds an additional rotational axis (usually A or B axis) to provide an additional cutting direction, reducing the need for re-clamping. However, there are still geometric limitations that cannot be fully addressed. The “3+2” design of a five-axis machining center typically involves adding an additional rotational axis (usually called the C-axis) to the three-axis setup. This design enables simultaneous rotation of the tool and workpiece through the rotational axis, allowing for synchronous machining of complex cuts on different surfaces. As a result, five-axis machining centers can quickly and efficiently cut complex workpieces, minimizing the need for re-clamping and repositioning. This design significantly improves both the efficiency and precision of the machining process. Compared to three-axis and four-axis machining centers, five-axis machining centers have superior capabilities in processing complex geometries and intricate surfaces, resulting in a several-fold increase in processing efficiency.

Different machine prices: Three-axis machining centers are the most commonly used and generally satisfy simple milling operations, so the equipment prices are relatively lower, typically around 29000usd to 36000usd. Four-axis machining centers, with an added rotational axis to the three axes, incur additional costs ranging from 7500usd to 15000usd. Five-axis machining centers have higher prices, generally ranging from 75000usd to 230000usd.

Machining characteristics: In three-axis machining, the tool direction remains constant throughout the cutting path. The cutting condition of the tool tip cannot be perfectly optimized in real-time. During five-axis machining, we can consider improving the cutting direction of the tool to ensure the optimal path of tool movement throughout the entire machining process. Additionally, in five-axis machining of workpieces, the tool can maintain a simultaneous linear movement direction, resulting in the best cutting performance. Compared to four-axis machining, where an additional rotational axis is added to a three-axis machining center, the rotational axis is limited to a 360° rotation in the horizontal plane and cannot achieve high-speed rotation.

 This characteristic is suitable for machining some box-type parts.

Different machining costs: The average cost for three-axis machining is generally around 9-10usd per hour, four-axis machining is around 15-25usd per hour, and five-axis machining costs around 60-75usd per hour. It can be seen that the investment and output of five-axis machining equipment are proportional, and the machining difficulty is high, typically requiring experienced and skilled technicians to operate.

With the continuous development and advancement of technology and the manufacturing industry, the widespread application of high-end complex products has driven the development of 5-axis machining technology. The demand for complex components with high precision and intricate surfaces has made 5-axis machining centers the preferred choice for customers. Of course, customers also consider the machining cost of 5-axis machining centers as a necessary factor to consider.

The pricing for five-axis machining centers can vary among suppliers and is typically determined by several factors. Here are some common cost factors:

Material cost: The type and quality of materials used in five-axis machining centers will impact the cost. High-performance metals and advanced composite materials can result in higher costs, and material selection depends on the customer’s design requirements, with different materials varying in performance and price.

Equipment and energy cost: The usage of equipment and energy, as well as the electricity rate from the power supplier, will determine the hardware cost of the five-axis machining center. Some suppliers may charge additional equipment usage fees based on the size and complexity of the workpiece.

Difficulty and cycle of machining: The difficulty and cycle time of the five-axis machining center are key factors influencing the cost. More complex workpieces require more machining steps and time, which can increase the cost. Therefore, cost-effectiveness should be considered during the design phase.

Software and labor cost: The software licensing and labor operation of the five-axis machining center are also cost factors. Some suppliers may charge labor operation fees based on the quantity of workpieces or the complexity of the process.

Quantity of workpieces: Typically, the machining cost for small batch production is higher compared to large batch production since suppliers prefer larger orders to optimize time and resources. However, Masion welcomes small batch orders and provides corresponding discounts.

In addition to the above factors, there may be additional costs related to special packaging, transportation, or other requirements based on customer requests.

The pricing structure for five-axis machining centers is a complex issue. Different suppliers of five-axis machining may have different pricing structures, and customers should choose the appropriate five-axis machining supplier based on their specific needs. Prior to selecting a five-axis machining supplier, customers should consider factors such as the technical expertise of their engineers, service quality, and reputation to ensure they receive the best value.

Regarding specific five-axis machining costs, prices in the market are typically around 50usd per hour. For a workpiece with dimensions of 1000×1000, the price may be around 80usd per hour. Masion provides five-axis machining services and offers reasonable quotes based on your workpiece, with competitive pricing and high quality assurance.

We usually understand the time that affects the production of five-axis machining from the following factors.

Complexity of the part design: If a customer’s product design is highly complex with multiple surfaces and holes to be machined, it will take more time to produce the product.

Choice of material grade: Generally, aluminum is easier to machine compared to other metal materials, resulting in relatively shorter processing time. However, if the material to be machined using five-axis technology is a harder material like stainless steel, titanium alloy, etc., the machining time will be longer, and the tools may be more prone to wear and damage.

Surface finish requirements: Five-axis machining typically involves rough machining and finishing stages. For parts requiring extremely smooth surface finishes, an additional process step may be needed. If only general surface finish requirements are necessary, the machining time will be relatively shorter.

Surface treatment requirements: Some customers may require post-machining surface treatments such as oxidation, plating, etc. This will increase production time, and there is a possibility of product damage during intermediate processes, leading to higher scrap rates.

Production scheduling: If it is a reorder of existing products, the speed will be faster, usually around 3-4 days. However, as material procurement, CNC machining, and other processes all require time, any delays in these stages can affect the overall production schedule.

Quantity considerations: For some precision parts requiring five-axis machining, if the order quantity does not meet the minimum requirements, additional processes such as wire cutting or laser cutting may be needed, which will consume more time and effort. This is especially true for customized high-precision precision components with small volumes and an imperfect supply chain, making it prone to supplier delivery delays.

After sample development, when moving to mass production of precision components, there may be process factors that are not conducive to large-scale production. For example, there may be no issues during CNC machining, but in mass production, it is found that some precision parts are not easily oxidized, requiring fixture treatments, etc.

Unexpected events involving skilled personnel in precision part manufacturing facilities. If there is a situation where there are no qualified substitute personnel, it will lead to a decrease in production capacity, especially for processes with a high level of technical dependence, which may result in delivery delays.

Other uncontrollable factors such as power outages, equipment failures, and other unforeseen circumstances. Companies should have contingency plans in place to deal with such situations to avoid being at a loss.

Overall, taking into account the above factors, the typical production time for sample five-axis machining at Masion is around 5-10 days, for small orders it is generally 10-15 days, and for large orders it is usually 30-35 days.
