CNC (Computer Numerical Control) routers are specialized tools that utilize computers to shape and cut various materials. The function of a CNC router rotary is to turn workpieces with an axis of rotation during the cutting process. With the assistance of rotopods or rotary attachments, these CNC machines are capable of cutting, shaping, and engraving cylindrical and cone-shaped objects.
Some popular types of CNC rotary routers are as follows:
Machine Size (Axis Travel)
The CNC rotary machine has a surface plate where the material to be carved is placed. The plate has two axes: the X-axis and the Y-axis. The X-axis is the horizontal line from left to right, while the Y-axis is the vertical line from down to up. The location where both axes meet is known as the origin. The movement of these two axes determines the machine's size or work area.
Spindle Power
The spindle serves as the carving tool in a CNC rotary carving machine. It operates on electricity supplied from the wall. The strength of its power is referred to as spindle power. The spindle comes with varied power levels for specific carving tasks. Small CNC routers utilize low power spindles, usually ranging from 0.5 to 1.5 kW. Mid-range CNC routers (entry-level to mid-level models) may have power levels from 2-3 kW. High-power spindles, typically around 4-5 kW, are found in professional or industrial models of CNC routers.
Rotation-Axis
Conventional CNC routers operate on two rotational axes (X, Y), allowing movement throughout the surface to create different carvings. Nonetheless, the CNC router with a rotary unit introduces an additional R-axis, which consists of a cylindrical object where the material to be carved is attached. This feature allows the machine to perform carvings on objects with circular shapes, such as columns or poles.
Feed Rate
The router's carving speed depends upon certain factors. Among them are the type of material used, carving depth, and spindle power. Generally, the carving speed varies with the machine model. For entry-level CNC routers, the feed rate may reach 30,000 mm/min, while mid to higher-level models have a feed rate of around 45,000 mm/min. Some advanced models may have a feed rate of 90,000 mm/min.
Rotary table
A CNC rotary table is an attachment or device that enables the CNC router to rotate and position workpieces with high precision during machining operations. It consists of a table, often circular, mounted on a motorized rotary axis.
Like any other carving machine, the CNC router machine with a rotary unit requires regular maintenance to operate at its optimal level. The health and longevity of the device largely depend on routine maintenance tasks. It's important to consider that neglect can shorten its lifespan and make it more vulnerable to breaking down or malfunctioning, which can lead to costly repairs.
Daily Maintenance
As part of daily maintenance for CNC rotary carver machines, operators should clean the work surface and make sure that no debris is left behind. They should also inspect the cutting tool to see if there are any signs of damage or wear, and check the machine's lubrication system to ensure that it is functioning properly and that there are no leaks.
Weekly Maintenance
On a weekly basis, users should calibrate the machine to ensure accuracy and consistency when carving objects. They should also check the spindle and be sure to adjust the speed and run out levels as required. Further, the tool has to be inspected and cleaned properly to remove any build-up of material or residue that happened during the course of use. It's also important to change the cutting tool if required, to ensure the quality of the carved objects.
Monthly Maintenance
Users should pay attention to monthly maintenance tasks of the 3D CNC rotary carving machine. It is a good practice to perform a complete system diagnostic on the tool to check its electronic control system and test to make sure all sensors and motors are functioning properly. More importantly, the air filtration system should be monitored and checked to see if there is any required maintenance. Users should also check the backup system to ensure that all essential files and data are safely stored and then, restore the system to optimize performance.
Woodworking:
For carpenters or woodworking studios, a CNC router rotary machine is an indispensable tool. It can be used to make beautiful curves, patterns or flutes on wooden furniture, musical instrument parts or decoration. The advantage of such a machine is that it can process workpieces of different shapes and sizes in a continuous, automated manner, which ensures a high degree of accuracy and efficiency. This is particularly important for carpenters who may have a large number of orders to fulfil in a limited period of time.
Advertising industry:
For the advertising industry, CNC rotary routers are the ideal equipment for producing advertising signs and company logos. With a rotary CNC router machine, sign makers can easily and accurately cut and engrave materials such as acrylic, PVC, and aluminum to create beautiful signs or brand logos in different shapes and designs. The machine's automation and precision allow the production of advertising products at high volume and low cost, thus meeting the needs of sign makers relatively quickly.
Decoration industry:
In decoration projects, CNC rotary routers can be used to deal with a variety of materials, including wood, foam, and gypsum, etc. The machine can make exquisite decorative components such as ceiling murals, 3D models, reliefs, etc., to fulfill the various stylistic demands of the design. In addition, the CNC rotary router can help decorators save time and manual effort through automated processing, which is especially important for large-scale or complex decoration projects.
Model production:
CNC rotary routers are also widely used in the field of model making. They can be used to carve and cut materials like plastic, foam, and wood to create architectural models, automotive models, or product prototypes. The precision and flexibility of CNC rotary routers allow model makers to quickly and accurately produce models, which facilitates the design and development process.
A CNC wood router machine with a rotary device can carve complex wooden objects like cylinders and arches. Normally, these machines are used in the woodworking industry. But they can also be found in the following industries:
Because the above industries heavily rely on the advantages of a rotary CNC router, their preferred choice will differ from a hobbyist's standard. It's important to note that an industry buyer will look at factors like the workpiece diameter and the machine's capability. The machine's capacity to handle high-demand projects and how seamless its integration is with other production lines become the top priority.
For example, if a furniture business needs to route 20 pieces of furniture each day, they will look for a rotatory router that has an automatic feeding system. With the automatic feeding system, they can achieve higher production rates every day.
An advertising or signage business will look for a router with a higher workpiece diameter. This is because the majority of their workpieces used for making signs have large diameters.
Industries expect a heavy-duty machine that can support continuous use. A machine with simple and fast operation will be preferred because it reduces employee training and improves workflow. A rotary axis CNC router with automatic loading and unloading capabilities is ideal for increasing production efficiency.
Overall, it's important to consider the machine's integration capabilities. Will it connect seamlessly with the business's current production line? Can it unwieldy or unload automatically?
