Common sense of engraving and milling machine parts

1. What are the basic common sense of the carving path of woodworking engraving machine?

When using CNC woodworking engraving machine to engrave workpieces, engraving can be divided into two-dimensional engraving and three-dimensional engraving. Drilling is divided into point drilling, contour drilling and area drilling. At the same time, we also provide the function of cutting the lines of badges. Below we will introduce some related terms and carving methods when carving with CNC engraving machine. I remind you that before using CNC engraving machine equipment, you must master the following basic engraving performance.

1, female, male

The so-called "intaglio carving" means that what remains on the carving material after carving is concave characters or patterns.

The so-called "orthographic engraving" refers to the protruding words or patterns left on the carving materials after the carving is completed, commonly known as orthographic or orthographic.

2. Carving depth

"Carving depth" refers to the maximum depth of machining. In three-dimensional carving, the depth of the carving path varies with the shape of the processed figure.

3, layered carving

"Layered carving" is used in 2D, 3D, lettering and image carving, with the feed not exceeding [] mm each time. It refers to the maximum depth of the tool entering the material every time, and the hard material is carved in layers for many times according to the experience value, and finally the designed carving depth is completed.

4. Mosaic path

The so-called "mosaic" is a design figure. After intaglio and male engraving, the two parts are called female die and male mold respectively. The two molds can be locked together seamlessly. Considering the influence of the cutter, when calculating the engraving path, one of them must choose "Mosaic Path".

5, tool compensation

In the process of machining, the cutter itself has a cutting width, and after adding "cutter compensation", the influence of cutter edge width on machining effect can be automatically eliminated.

6. Direction of rotation during edge hooking

When cutting and milling the bottom, choosing the appropriate rotation direction of the hook edge can make the side of the machined object smoother.

7. Bottom milling method

In two-dimensional and three-dimensional path calculation, bottom milling is a common processing method, that is, milling off the redundant parts of objects or people. Common bottom milling methods are: horizontal bottom milling, longitudinal bottom milling, forward 45-degree bottom milling, reverse 45-degree bottom milling and circular bottom milling, but no matter which method is selected, the result is the same, but the tool path is different during machining.

8, tool selection

When processing objects with different materials and hardness, in order to ensure the processing efficiency and effect, it is necessary to choose appropriate processing tools. Users can set and name their commonly used tools.

2. How much do you know about the common sense of CNC engraving machine?

Introduction of drive system

At present, the driving system of engraving machine is mainly divided into two categories: stepping system and servo system. Step-by-step system is dominant because it is economical and can meet the use requirements of ordinary customers. Stepping system belongs to semi-closed loop system, and its accuracy is calculated by step angle. Servo system belongs to closed-loop mode with measurement feedback system, so customers with high precision, high power, stable operation and high requirements can choose machines with servo drive system (slightly more expensive). At present, there is also a semi-private server system on the market, which is an improved stepping system. Please pay attention when choosing a machine. (Domestic and imported)

Control system:

At present, Wei Hong, DSP operating system and mach3 are the leading companies, and Taiwan Province Baoyuan and a new generation control system are imported.

Drawing software:

General purpose, Wen Tai, sculpture, type 3, artcam.

Transmission mode of engraving machine:

At present, the engraving machine is divided into three transmission modes: lead screw transmission, rack transmission and synchronous belt transmission.

Advantages and disadvantages of screw machine:

Lead screw transmission is the transmission mode of engraving machine when it originated. It has the characteristics of high precision, slow running speed, high environmental requirements and relatively short service life. The Y-axis single screw is not easy to be too long (the model cannot be too large) and easy to shake when running at high speed. If the installation accuracy is not high, the Y-axis lead screw will break down after a long running time. If the accuracy is too high, the Y-axis double screw structure can meet the requirements, and the general processing speed is about 7 meters. (Mainly applicable to advertisements, wood products, small handicrafts and lighter stones. Any carving material can be processed according to different tools. )

Advantages and disadvantages of hanger machine:

Rack machine is an upgraded version of the existing screw machine, which is newly developed because the screw machine can not meet the requirements of high-speed machining. Its speed is fast, its environmental requirements are not harsh, its service life is relatively long, and its accuracy is lower than that of the screw machine. The Y-axis and X-axis of the rack machine are driven by the rack and pinion, and the Z-axis is generally driven by the lead screw. The accuracy requirement is mainly determined according to the meshing accuracy of the guide rail and the rack and pinion. The size and length of the machine can be large enough to facilitate maintenance. Generally equipped with manual oil injection system, it is suggested that the processing speed can reach about15m. (Mainly applicable to the processing of woodworking products, the cutting of paint-free doors, cupboard doors, solid wooden doors, screens and other plates, the hollowing out of reliefs, the processing of advertisements, and the selection of materials such as stone and marble according to tools).

Synchronous belt drive:

Synchronous belt drive is mainly used in laser engraving machine and plasma cutting, which has the characteristics of light weight, high precision and easy maintenance. It is easy to relax after long-term use, which will affect the machining accuracy. The laser machine is mainly used for advertising, handicraft carving, cloth, shadow carving, line carving, etc. of some nonmetallic materials such as leather, glass, stone and crystal. They can also be processed on a few metal materials, and the price range is related to the power of the laser tube.

3. What is the common sense of using jade carving machine?

What is the common sense of Kobilong jade carving machine? 3. Requirements for engraving and editing files: [1] The engraving file is G code, which is the instruction code of the stone carving machine.

Fast move and move instructions. The zero point in editing software is the origin of engraving machine processing.

When loading the cutter, first put the spring collet with proper size into the taper hole of the spindle, then put the cutter into the middle hole of the collet, clamp the flat groove of the spindle neck with a random small wrench to make it unable to rotate, and then turn the spindle nut counterclockwise with a large wrench to fasten the cutter. Engraving machine manufacturers talk about material and workpiece clamping. The materials processed by this equipment are: plexiglass, bicolor board, marble, hard rubber, brass, copper, hard aluminum, stainless steel, etc.

4. What safety precautions must be paid attention to when using engraving machine?

First, the blade of the meat cutter is very sharp. You should not touch the blade when loading and unloading the knife, so as not to hurt your hand.

Second, all the rotating moving parts of the machine can't touch during the movement, including the spindle, cutter and other parts. Especially the high-speed rotating body, it is difficult to judge whether it is running or not from the appearance. When operating these components, you must first carefully confirm their working conditions.

The three-axis linear motion of the machine tool includes the beam moving along the X axis, the pulley moving along the Y axis (beam), and the spindle moving up and down along the Z axis, with high speed and large inertia. No one is allowed to get close to these parts to avoid collision or extrusion. Four, in the process of machining, the tool may break, chips, small workpiece may fly out, be sure to use dust cover protection device.

Fifth, pay attention to the safety warning line of the machine. In order to prevent the engraving machine from harming people's life and health during operation, it is necessary to set up a safety warning line while installing equipment.

The safety warning line is attached to the ground, and the minimum distance from the machine in the front and back direction is 0.2m, 1m and 0.6m respectively. When the machine is running, no one is allowed to cross the safety warning line.

5. What knowledge do you need to master to operate the woodworking engraving machine?

Training before use is necessary, otherwise don't operate it, otherwise it will easily break down and damage the life of the CNC woodworking engraving machine.

Operating steps:

1, theoretical basis of CNC woodworking engraving machine;

The training work must start from the theoretical training work, and the operators must pass the theoretical examination before they can carry out practical training. If the theoretical training fails, the operation training cannot be carried out.

2, the use of CNC woodworking engraving machine:

After theoretical training, we should also train the tools of CNC woodworking engraving machine. Operators should be familiar with the rotating speed and walking speed of common tools and engraving motors, and pay attention to 7A64E4B893E5B19E313337623430, etc. Operators must be familiar with the application of tools.

3, the application scope of CNC woodworking engraving machine:

Operators must be familiar with the range of plates carved by CNC woodworking engraving machine, different materials, different thicknesses, different finished product sizes, etc. Familiar with different carving methods of different materials.

4, CNC woodworking engraving machine software operation:

Only after passing the above training can software training be carried out. Software training mainly focuses on the user application field; For aspects that users don't need, you can learn by yourself according to the training manual. The requirements for the software are: all kinds of typesetting, all kinds of operations, path generation, and the ability to quickly find path errors.

5. Operation training of CNC woodworking engraving machine: After all the above training is completed, the trainees will explain it, and the operators will understand and assess it: the operators will be trained in operation safety and operation precautions, and the operators can only conduct trial operation training of CNC woodworking engraving machine after the trainers sign the safety matters.

6, CNC woodworking engraving machine operation matters needing attention and engraving machine maintenance training.

6. What should I pay attention to in the safe operation of woodworking engraving machine?

1) Before operation, check whether the handles of various parts of the woodworking engraving machine are normal, add lubricating oil according to the regulations, and try it out at low speed 1~2 minutes before operation.

(2) Wear work clothes before work, and female workers should wear working caps. Do not wear gloves when operating. (3) Clamping the workpiece should be smooth.

Loading and unloading, tool alignment, measurement, speed change, spindle fastening and machine tool cleaning must be carried out after the spindle of the engraving machine stops. (4) It is forbidden to place measuring tools, workpieces and other sundries on the workbench of woodworking engraving machine.

(5) When the woodworking engraving machine is started, check whether the positions of the workpiece and the milling cutter are appropriate. (6) When the woodworking engraving machine automatically feeds, the workbench cannot go to two limit positions, and the limit block should be stabilized.

(7) When the woodworking engraving machine is running, it is forbidden to clean the machine with bare hands or cotton yarn. People can't stand in the tangential direction of the milling cutter, let alone blow chips with their mouths. (8) Before starting the machine, the arbor, pull rod, chuck and cutter should be installed and tightened, and the spindle rotation of woodworking engraving machine should not be used to help loading and unloading.

(9) After use, turn off the power supply, clean the machine tool, put the operating handle of the engraving machine in an empty position, and move the workbench to the center.

7. What's the difference between engraving and milling machine and engraving machine?

The engraving machine is mainly used for engraving plates, and is widely used for engraving bicolor plates or acrylic plates. The once feed depth of engraving is about 1mm-3mm, which is widely used in signs and signs.

In terms of mechanical structure, the engraving machine is light in design, fast in X-axis and Y-axis movement, and short in Z-axis travel, which is suitable for engraving materials of 5 mm-8 mm.. The engraving shaft head is equipped with a spring head, which is used to flatten the thin plate below 3mm during engraving.

The engraving spindle is connected to a motor with a larger diameter through a belt, which improves the rotating speed and makes the quality of the engraved workpiece smoother. The carving tool used is long, and the length is about 15.

9cm, diameter 4. About 35mm.

Due to the limitation of design, it is suitable for high-speed engraving with small cutting amount. Carving and milling machine can be understood not only as carving, but also as cutting and planing machine.

For example, three-dimensional carving, although the gap is large, 200mm wide material can be completed at one time, and the amount of feed at one time is quite large. The available cutter diameters of the engraving and milling machine range from 1mm to 16mm, and the cutter length is 50~80mm.

We can use it flexibly, fine knives do fine work and coarse knives do big work. Because the machine design pays attention to heavy load, the frame is rigid and the Z-axis stroke is large, it can not only be used as a small engraving machine, but also cut thick plates at high speed, and the feed speed can reach 20mm-30mm at a time, which is impossible for engraving machines to manufacture.
