3+2 Axis CNC Machining: How It Works and Why It Matters?

 


If you need China CNC machining services, look no further than HLH Prototypes. We offer CNC machining for rapid prototyping and end-use manufacturing to provide precise parts quickly and cost-effectively.

The process starts with a billet or solid block of material, and we cut away at it precisely with a series of drill bits and tools to form the part according to your design. As seasoned machinists, we offer a range of axis machines to meet every need.

3+2 machining is a specialized technique that combines the precision of 3-axis milling with the flexibility of 5-axis machining. In this process, a cutting tool is tilted and locked in a fixed position while the worktable rotates on two axes. This is distinct from full 5-axis machining, where the tool rotates continuously. 3+2 machining is also known as 'positional 5-axis machining' due to the fixed position of the cutting tool.

In this blog, we share how 3+2 axis machining works and its importance to your manufacturing process.

Faster, more precise cutting

The biggest advantage of 3+2 axis CNC machining is the ability to use shorter and more rigid cutting tools that allow for closer proximity between the spindle head and workpiece while maintaining a favorable tool angle. Because of this shorter tool length, machining speeds are faster, and there’s minimal deflection. The result? Improved surface finish, higher dimensional accuracy, and reduced cycle times. Product engineers and designers turn to China’s CNC machining services to save even more money and time.

Should you use it?

3+2 machining is practical for machining deep cavities in complex molds where traditional 5-axis machining might require longer and more slender tools (which are prone to chatter and deflection) or extensions (which can create clearance issues). Furthermore, this type of machining also allows for the direct machining of steep walls on standing mold cores and undercuts in cavities to reduce the need for EDM.

If you’re not sure whether to use 3+2 axis CNC machining, don’t hesitate to contact us for a project review. Our team in China can discuss our CNC machining service with you so you can make informed decisions.

Tips On Choosing The Right Prototypes Plastic Parts For Your Need

  Are you building a  prototype plastic part ? It's crucial to pick asuitable material, but that process can become intimidating as different plastics vary in durability, aesthetics, and strength. Even when prototyping, you’ll want to produce a production-grade prototype that lets you evaluate your product's performance in the real world. Here are some tips to reduce your guesswork in choosing plastics for your prototype.   Consider these critical factors.   Know the purpose of your part and its mechanical functions. You should also consider your manufacturing processes, such as CNC machining, injection molding, or 3D printing. Moreover, determine the quantity, the cost, and the lead times.   Explore commonly used plastics   Reputable manufacturers constantly update their selection of plastics, but these are the most common types you can consider for your  prototype plastic part :   ·         Acrylonitrile butadiene styrene (ABS): This is a strong material w

Different Types of 3D Printing Prototypes

Additive manufacturing lets you build three-dimensional objects based on your digital drawing model. It creates a custom   3D printing prototype  by adding materials one layer at a time or by sintering or fusing powdered materials, depending on the method you use.   Technologies have come a long way and introduced more 3D printing methods to help you make prototypes quickly, accurately, and cost-effectively. Here are the most common types you may want to know. Stereolithography SLA 3D printing is among the oldest and most versatile additive manufacturing technologies. It builds the object layer by layer using a photocurable resin cured with an intense UV laser in the build platform. The result is a  3D printing prototype  with a good surface finish and optimum accuracy to the CAD. The process involves support structures to keep the material in place while printing, but these are removed afterward. This technology is ideal for making aesthetic models and bespoke or low-volume pr

Rapid Tooling: A Perfect Speed to Market Product Development Solution

One of the greatest challenges that product manufacturers and designers face today is finding ways to speed up time to market. With consumer demands leaning toward rapid product development, manufacturers and product designers feel the pressure of having to churn out products in the fastest time possible. Just the same, new product development still requires a prototyping stage in order to ensure the feasibility of the product design, including its general shape and form, assembly, and functionality. Thanks to new technology, rapid tooling methods are becoming increasingly commonplace, enabling manufacturers to reap the benefits of much faster methods to create prototypes, which in turn speeds up product testing, final production, as well as its release into the market at large. Rapid tooling offers faster lead times of mere days instead of weeks or months, just like conventional manufacturing ways. Five to ten days is already a stretch when trying to get at least 50 prototype
