The desktop milling machine is indispensable for builders. It allows you to do a lot of woodworking. Modifications with CNC are characterized by their convenience and high quality work. The main parameters should include power, frequency and dimensions. A standard bench-top milling machine consists of a saw blade, longitudinal racks, a spindle unit and a control unit. Motors can be used at different frequencies. They are installed with CNC most often on a working platform.
Horizontal milling machine
This type of benchtop milling machine is great for corner cuts. According to experts, the market has many powerful models. The advantage of these machines also lies in the high frequency. For many models, the operator is able to independently adjust the cutting height. If we consider devices with wide racks, then they use an adapter with a flywheel. There are also modifications to three supports, which are characterized by high precision cut.
Vertical milling devices
Tabletop CNC milling machines for this type of wood are typically manufactured with commutator motors. Racks can be installed on special linings. Nowadays, there are many modifications with one working surface. They are great for processing small planks. V-belt drives are mainly installed above the adapters.
In order to control the CNC, power supplies of 200 and 230 V are used. Quite often, machines are made on cast-iron frames. They have high strength and compact dimensions. If we talk about the parameters, then the frequency of these machines starts at 2300 rpm.
Universal models
Recently, a universal drilling and milling machine (bench-top) based on a single-phase motor is in demand. The frequency indicator for the models is approximately 3400 revolutions per minute. Modern machines are made on two flywheels. The cutting angle they have is adjustable with a handle. It is also worth noting that there are devices with holders on the market. They are great for turning. The permissible weight of the workpieces depends on the strength of the bed. It is also worth considering the size of the workspace itself.
Mini models
The compact drilling and milling machine (benchtop) is made on the basis of a single-phase motor with a low frequency. The most common modifications are with one flywheel. It is also worth noting that devices with speed controllers are available on the market . The bed on a compact desktop CNC milling and engraving machine is installed under the overlays. Longitudinal supports can be mounted directly on the frame. Modern models are well suited for sharpening strips. According to the system of workpiece settings, devices may differ.
Devices with horizontal spindle
Modifications of this type are made on the basis of a two-phase motor. Modern models are able to boast of high frequency. In this case, the power is approximately 5 kW. There are many pendulum mechanisms on the market. The beds are made with double lining. Some modifications are not suitable for metal processing. CNCs are most often installed via contactors.
The saw blade in the devices is controlled by a shaft. There are also modifications based on three-phase motors. Their frequency indicator reaches a maximum of 3100 rpm.
Vertical Spindle Models
The desktop milling machine with a vertical spindle is great for wood processing. With its help, you can engage in the longitudinal cutting of not only the bars, but also metal plates. Spindle units in devices are usually mounted on clamps. The most common modifications on the market are two racks. The maximum power of machines of this type reaches 5 kW, and they are installed collector type.
Directly CNC applied contactor type. Many experts say that it is worth choosing devices without a casing. First of all, they weigh a little, and additionally the frames are more rigid. Some devices are sold with dust collectors. Spindle units can be mounted on a frame or bed. To adjust the cutting depth, use the handwheels or adjusters.
Wide support machine
The desktop milling machine with a wide support is suitable for processing whetstones. Also, modifications are often used for metal workpieces. In this case, a lot depends on the type of motor. Modern models are made with commutator engines, which operate at a frequency of 3100 rpm. Some devices are made with longitudinal racks.
It is also worth noting that there are modifications with two fittings. They are installed only contactor CNC. At the same time, power supplies are suitable for 300 watts. The working surface is most often used with rubberized pads. Devices are often used to sharpen plates. The angle of the cutter is regulated by the handwheels, which are connected to the terminal box.
Console models
The cantilever machine (benchtop, milling) allows you to control the milling process from a distance. A large number of modifications are made with channel clips. The spindle units are mounted on frames and are regulated by the flywheels. Directly beds are used with linings and without them. It is especially important to note that the machines differ in frequency and power. Some modifications are more suitable for milling plates. However, they must not be used for the treatment of steel surfaces. Power supplies can be installed with different conductivity.
If we consider a simple modification, then it has only one regulator for the position of the rack. In this case, the CNC is connected to the unit via the console. According to experts, modifications to drive units are ineffective. Beds under them are often used without clamp support. The limiting angle of the cutter for these machines depends only on the shape of the spindle unit. It is also worth considering the length of the working rack.
Models with a support
The desktop metal milling machine with caliper is primarily aimed at the quick processing of workpieces. The control units are used in two and three modes. At the same time, motors are selected, as a rule, of a two-phase type, and they are able to operate at a low frequency. If you believe the experts, then modifications with the top arrangement of the power supply are very popular. Racks on the machine (desktop, milling) are mounted above the frame.
Lining is most often used rubberized type. Transmission units are installed on two and three contacts. Devices are well suited for processing metal plates. It is also worth noting that there are models based on single-phase motors. They have a very high power consumption. In this case, the frequency does not rise above 2100 revolutions per minute.
Devices with additional stops
The desktop metal milling machine with additional stops is classified as universal. Most models are suitable for processing plates and bars. Some modifications are able to boast of high frequency and low power consumption. CNC blocks on a desktop milling machine are often installed contactor type. Devices differ in the type of spindle units.
Additionally, it is worth noting that modifications are made with and without support. Many machines work with small bars. It is very difficult to call these devices compact. Drive blocks are mounted most often on blocks. Manufacturers offer many modifications with dust collectors. Cases are used in varying degrees of density. Also, modifications differ in moisture resistance. The width of the work area averages 22 cm.
