How to use a CNC rotary cutting machine?


With the progress of science and technology, digital servo control technology is also applied to the production of rotary cutting machines. In recent years, CNC rotary cutting machine has appeared. The emergence of the CNC rotary cutting machine not only improves the quality and accuracy of veneer production but also greatly improves the production efficiency and the automation of the whole machine.

How does the CNC rotary cutting machine work?

The main actions of the CNC rotary cutting machine are:

① When the wood section is stuck and the wood core is put down, the chuck shaft must have an axial telescopic movement;


② For the peeling veneer, there must be a coordinated movement between the rotation of the chuck shaft and the feed of the tool post, and a series of mechanisms for adjusting the thickness of the peeling;


③The CNC rotary cutting machine must have fast feed and retreat motions to improve productivity.

How to adjust the uneven surface of the CNC rotary cutting machine?

Sharpen the tool again and check the straightness of the blade. If the roller bounces, check whether the bearing is damaged or the radial clearance is too large. Check whether the shaft head of the CNC rotary cutting machine is deformed due to the bending of the wood or the excessive squeezing force of the oblate, which affects the flatness of the plate. Replace the new pattern roller in time or correct it by yourself. If the height of the knife is too low or the knife gap is too small, the pressure of the single and double rollers and the knife on the wood is too large, which can also cause irregular deformation of the wood and directly affect the flatness of the board. Please read the tool position measurement method diagram carefully for specific measurement methods.


When the wood is too thin and bent, the wood will be forced to be straight and peeled due to the strong automatic feeding pressure of the machine during the working process of the CNC rotary cutting machine. When the wood is peeled out of the machine, it will follow the original bending. Shrinkage causes unevenness. During the growth process or long-term storage, the wood will always have the characteristics of one side facing the sun and the other side facing the shade. Therefore, the density and the degree of dryness and wetness on both sides of the wood are different, which causes the flatness of the peeled board surface to be different, so the choice of wood is also a problem.


What is the relevant information about the CNC rotary cutting machine?

1. The axial feed speed of the chuck shaft of the CNC rotary cutting machine should make the time between the retraction room of the tool bed and the loosening time of the wood core equal. There are two ways of axial movement of the chuck shaft: screw drive and hydraulic cylinder.


2. The diameter of the chuck of the CNC rotary cutting machine determines the smallest possible diameter of the wood core during peeling.


3. The power of the main drive of the CNC rotary cutting machine and the power of all motors on the CNC rotary cutting machine (in kilowatts) determine the thickness of the veneer that may be peeled and the power consumption of the veneer peeling.


4. The length, width, and height of the external profile of the CNC rotary cutting machine are measured according to the most protruding part of the machine tool. The length and width determine the plant area required to install the machine tool.


With the increase in market demand, the types of CNC rotary cutting machines are also expanding. To meet these growing demands, Shenzhen Test Laser Equipment Co., Ltd. has various CNC rotary cutting machines and they are all more effective, reliable, and consistent.
