CNC engraving and laser machines and their applications

Engraving machines This is equipment with which inscriptions and drawings are created on metal and stone products. The machine consists of a base on which a bypass sensor is attached, cutting parts and a mechanism that transfers the necessary text or pattern to the product
The following advantages of working with a CNC machine can be distinguished:
x High production speed;
x 2D and 3D engraving;
x Accurate image transfer to detail;
x Working with fragile products of various shapes
Engraving machine working principle
The equipment has a USB connector through which it connects to the CNC device. Programs with the functions of figured cutting, milling and three-dimensional carving are already installed on this device
The process is considered automatic, since the observer only needs to set up the machine and turn it on, and then all that remains is to observe the work. The product is attached to the machine itself and a cutter for hard or soft materials is installed. Then, in order to check the correct setting of the CNC program, a test part is installed and processed
It is important to also check the idle speed before starting work Namely:
x Motor commands;
x Spindle rotation;
x Mechanical on/off table feed
Milling of the part can be carried out by up-and-down or climb milling. The first type of processing is suitable for viscous materials, and the second for fragile and valuable products
Engraving machines can be divided into laser and shock-engraving. Impact-engraving designs have a low processing speed, but transfer the pattern with almost 100 percent accuracy. Laser machines work with the product using laser beams. Laser cutting machines
This device with high precision processing of details Laser beams are able to cut the product perfectly evenly, engrave a pattern or combine several products into one
The equipment works as follows. A drawing with the necessary parameters is loaded into the CNC program. Then the laser beam automatically melts the material, creating the desired patterns. The whole structure consists of a table, which is a supporting support. Flying optics are installed on it. These are mirrors that prevent the beam from scattering. There is also a laser lamp, which enhances the burning sensation on the product
What are the advantages of using a laser machine?
x Works on any material;
x Work of any complexity;
x High performance;
x The machine does not release dust and debris;
x Low chance of product damage
Types of laser machines
Laser machines are divided into three groups First – CO2 engravers They use carbon dioxide for cutting Can affect any product – from leather to stone Such equipment is inexpensive, saves energy and works at a decent speed, so it is often purchased by businessmen for their small industries
The second group – solid-state laser machines They are used to apply inscriptions and logos on plaques and monuments Long radiation affects even metal with precision
Fiber Engravers – the most reliable type of laser machines They use fiber-type light guides, so they consume little energy The equipment itself is very compact in size, it can be easily moved by one person Therefore, miniature products are more often made here
What is produced on laser machines?
The most popular products that come out of laser machines are: blanks for production, stencils, interior items, signboards, decorative elements. These machines use, most importantly, because of their accuracy. The laser beam is able to cut parts, leaving smooth edges that do not need further processing< br /> Another plus of a large production using a laser – the equipment quickly produces the same products It is enough to set the parameters of the desired sample in the program Since no post-processing is required, wholesale production can produce thousands of parts per hour of work
