Pay attention! Before you buy a CNC wood milling machine, you definitely need to check for a certificate. This document guarantees the compliance of the instrument with all the standards established by the state, as well as the safety of its use.
The device of a wood milling machine for a home workshop
Most milling machines have the same structure. The standard design of a woodworking tool consists of:
- milling table;
- bed frames;
- spindle for cnc milling machine;
- cutting element.
The carriage is included in the additional equipment of some models. This element allows you to process workpieces at different angles.
The frame of the milling machine for wood is a monolithic part that is stable. It is not affected by vibrations and vibrations that occur during the operation of the tool. The shaft is mounted on a caliper, the upper part of which is removed through a hole in the table. If necessary, you can always adjust the height of this element by adjusting it to the master’s requests. A spindle with a plug-in design and a cutting part are installed on top of the part. The type of cutting element is selected taking into account the task.
As a cutting part can be used:
- milling cutters;
- drilling and cutting elements for wood milling.
The higher the rotational speed of the spindle, the higher the quality of material processing. This nuance should be taken into account when performing operations that need precision. The tool has a special structure that makes it possible to safely and quickly change the cutting element.
If milling needs to be carried out in a straight line, it is impossible to do without using a guide bar with a movable structure. Special slots are provided for fixing the tool stops. Many modern models of devices, regardless of whether there is a carriage in the configuration, are supplemented with an industrial vacuum cleaner. It effectively and quickly removes chips and dust from the work area.
Which is better to buy a wood milling machine: types of structures and characteristics
