Woodworking features on laser and milling equipment
Beautiful, cozy, wear-resistant wooden products are in demand in everyday life and various sectors of the national economy. In addition to aesthetics, practicality and environmental friendliness, wood has another remarkable property – it is perfectly processed by any mechanical methods and laser. In the carpentry business, furniture production and advertising business, milling machines are widely used. Laser equipment is perfect for making souvenirs and engraving works.
Among the many operations that can be performed by a mill, straight and complex cut, drilling, making grooves, spikes, shaped edges, processing of large-sized and bulk products. CNC milling equipment allows you to create various decorative patterns, images, inscriptions on wood, perform 3D volumetric cutting. The use of software control not only improves the speed and quality of processing, but also enables the production of any number of absolutely identical products using the same layout.
Whichever mill you use (manual, desktop or professional stationary), the process begins even before using the equipment. First of all, it is necessary to transfer the outlines of the future product to the material or to prepare an electronic layout (for CNC). Further, the material is examined, the purity of which is especially important for engraving. If necessary, eliminates the error of wood, it is cleaned to the optimum state to remove dirt, chipping, chipping.
Milling wood processing process
Having material with an ideal surface it is possible to start work. It is important to choose the right tool depending on the planned operation (end, shaped, grooving, edge milling cutters) and the characteristics of the material (for soft wood – high-speed, for solid – carbide). To avoid tearing the fibers out of the processed array, it is necessary to calculate the spindle rotation speed and feed rate that is optimal for the breed used. Too high speed reduces processing quality. Among the errors also occur:
- use of a large diameter cutter or increased length at high revs;
- using a thin milling machine for thicker workpieces;
- exceeding the critical depth of cut. The maximum rate for a single pass is for soft species (pine, spruce, linden, poplar) – one and a half of the cutter diameter, for hard (beech, cherry, birch, apple, oak) – one diameter, for hard (walnut, hornbeam, ash, acacia) ) – floor diameter.
Therefore, in the process of processing should closely monitor the operation of the equipment. The screech cutters, the fallen edges indicate a wrong tool or cutting mode, and you need to take measures to eliminate the deficiencies in time.
The advantages of laser cutting and engraving wood
The use of laser technology when working with a wooden array provides high-precision processing. The material is well cut by the beam, if its thickness does not exceed 10-15 cm, depending on the properties of the wood. The soft rocks — pine, spruce, aspen, poplar — are more amenable to laser processing; the greater the density and hardness of the tree, the more difficulties it can cause. Airflow should be used to remove chips and dust. The laser is widely used for small parts, complex contour, openwork cutting, artistic engraving. CNC laser equipment allows you to make unique products, implementing the most daring ideas of the designer.
Laser engraving is carried out quickly and in exact accordance with the given layout, the images are clear and high quality, whether it is an inscription, a drawing or a photo. Since the engraving takes place without mechanical contact between the instrument and the surface, work is possible with wood species that are easily deformed by mechanical methods, that is, prone to formation of chips, cracks, and terry. The thermal effect of the beam leads to a change in the shade of the wood in the processing zone, which makes the image distinct and deep. By varying the laser power you can achieve interesting visual effects by performing fine art work.
