And both can cut, engrave, drill, mill grooves, etc. We often say that the CNC nesting machine is an upgraded model of the wood router machine. So what are the similarities and differences between these two machines?
Similarities
Similar appearance and configurations.
Both the wood CNC router and the nesting CNC machine mainly consist of mechanical parts and electrical parts. The mechanical parts include frame, worktable, gantry, etc. The electrical parts mainly include motor, driver, inverter, controller, spindle, control cabinet etc. So these two types of machines possess similar appearance.
Similar functions and applications.
Both the CNC wood router and the nesting CNC machine are capable for wood working and can cut, engrave, mill, drill and groove various wood materials. These two types of machines have wide applications in furniture industry. They are able to make panel furniture, cabinets, cabinet doors, doors, office furniture and customized furniture etc.
Similar with the multi-process or ATC CNC wood router, the nesting CNC machine also has multi-process or automatic tool charger models. Therefore, both the CNC engraving machine and the CNC nesting router can achieve multiple processes simultaneously without frequent showdown for changing tools manually. This greatly saves manpower, reduces the non-production time and increases processing efficiency.
Similar operations.
The CNC router machine and the CNC nesting machine are numerical controlled machines and both of them have high automation level. They use corresponding computer software to make layouts and designs and the machines complete the subsequent processes automatically. No additional human intervention is needed. Both these two machines can significantly reduce human cost, improve production efficiency and reduce material loss.
Similar performance.
Both the CNC wood carving machine and the nesting machine have performance of high precision, high efficiency and high production. During the course of processing, the operators are able to see the whole process to the maximum extent. And at the same time the machine provides protection and reliable safety features for the operators.
Differences
Functions.
The CNC router machine is mainly used for simple cutting and 2D and 3D patterns engraving, such as relief and three-dimensional sculpture. And the CNC engraving machine with a rotary axis is also capable for 3D engraving on cylindrical workpieces.
The nesting CNC machine is mainly for cutting a wood panel into different sizes and is the dedicated equipment for flexible cutting, drilling and grooving of panel furniture. In addition, the CNC nesting machine can also engrave simple grooves and tenons on the board material.
So compared with each other, the CNC wood router has more functions, wider applications, and richer products. The CNC engraving machine can also cut materials, but its frame structure and mechanical parts determine that it is not capable for long-time cutting. And the cutting speed is relatively slow. Otherwise, it will cause frame deformation and increasingly low precision, which will affect the service life of the CNC router.
Applications.
Compared with the nesting CNC machine, the CNC wood carving machine has wider applications. Except for panel furniture, use of the wood CNC machine can also involve in such industries as advertising, crafts, artworks, molds, electronics, construction, packaging and printing, decoration etc. In addition, the wood CNC router can also cut and engraving acrylic, stone, plastics, foam, and soft metal.
However, the CNC nesting machine is mainly for the flexible cutting, drilling and grooving wooden panels for furniture. And it mainly manufactures the home & office custom panel furniture, such as household furniture and office furniture.
Dimensions.
The CNC engraving machine is available in a wide range of sizes, and different sizes are suitable for different projects. For example, the CNC router with worktable area of 600*900mm is able to make advertising signs and crafts. And the 4th axis wood router machine with worktable area of 2000*4000mm is capable for making complex wood furniture with 3D engraved legs.
The CNC wood cutting machine is mainly used to cut wood panels for cabinets, wardrobes, cupboards, shelves etc. So this type of machine is mainly available in large size, such as 1300*2500mm, 1600*3200mm, 2000*4000mm etc.
Configuration requirements.
As the CNC router is available in many types, the configuration requirements vary for different models. For instance, the mini or desktop wood CNC router with simple functions may not need too high configuration. While the ATC CNC engraving machine for 3D engraving or construction purpose may require ATC, rotary axis, high power spindle or other high level of configuration.
The average cutting speed of a nesting CNC router can reach 5m/min. And the panels cut out should be free of defects such as broken edges, gaps or wavy grain. Therefore, the nesting CNC machine needs high overall configuration requirements in order to accommodate the long-time, rapid, high precision and heavy load cutting work.
Frame.
The frame structure of the CNC wood router is not suitable for long term cutting work, because it may deform the frame, reduce the processing precision and wear the machine. However, the CNC panel cutting machine adopts heavy machine frame made of a welded steel construction and stable mobile gantry. It is more sturdy and endurable against large cutting force and impact. This ensures that the machine will not deform during long term and high speed operation.
Spindle.
The wood CNC router may be equipped with spindles of different power for different purposes. For example, for mini CNC router with simple cutting requirements, a 3kw spindle may be sufficient; while the ATC CNC wood carving machine of large working size may require a 9kw spindle.
The CNC nesting machine generally adopts high power spindles, such as 6kw, 9kw, 12kw etc. due to high cutting speed and long time work. Besides, the large power ATC spindle helps guarantee powerful functions, stable performance and excellent cutting results.
Worktable.
The CNC engraving machine can, if you require, be equipped with an aluminum T-slot working table, which is more cost-effective. For higher processing requirements, the vacuum T-slot working table is also available. However, most nesting CNC machines adopt the vacuum worktable to fix the panels to avoid movement during the cutting process. The vacuum worktable consists of several independent zones. Therefore, a single absorption zone can be switched on for cutting small size panels for the purpose of saving electricity.
Control system and nesting software.
The CNC router machine and the nesting CNC machine may use different control system and software. The CNC nesting router has dedicated nesting software for designing the cutting path, which maximizes the utilization of the panels. Besides the nesting software can automatically break up an order and carry out auto cutting process with simple operations.
Degree of automation.
Compared with the common CNC router machine, the CNC nesting machine has a higher degree of automation and intelligence to meet the high efficiency and high production requirements.
The common CNC wood carving machine may not have an automatic loading and unloading platform or device. So there is a need to feed and discharge materials manually. While most nesting CNC machine is equipped with automatic loading and unloading mechanism. The large panel on the lifting platform is automatically pulled to the position with a positioning device by the suction cup of the machine for cutting. And the finished panel is also automatically pushed to the discharge platform.
Some nesting CNC machines are also equipped with two working platforms, a drilling unit, an automatic labeling device or other automatic systems. All these automatic mechanisms guarantee the high efficiency and high output of the nesting CNC router.
