When it comes to CNC hand plate processing service, you must think of 5-axis CNC hand plate processing. Choosing the right processing plan will lead to the victory of consumption.

CNC hand plate machining is a program used in most manufacturing operations and is widely used in most industries. CNC stands for computer numerical control, which deals with the operation of different machine tools (such as lathes, routers and milling machines) using one or more computers.

5-axis CNC prototype machining is an absolutely excellent CNC prototype machining, which can be used to consume parts and final products from a variety of materials such as plastics and metals.

However, when it comes to detailed 5-axis CNC prototype machining, the first impression of most people is: high technology, high price and difficult operation, but is 5-axis machining really like this? The following paragraphs will introduce you to 5-axis CNC prototype machining from three important aspects.

CNC hand plate processing

1. What is five axis machining

This is a program that involves using CNC to move cutting equipment or different parts on five different axes at the same time. This provides space for consuming very complex parts, which is why 5-axis CNC milling is very common in aerospace operations. One of the most important factors contributing to the use of 5-axis CNC hand plate processing machine tools is the need to improve the proficiency and reduce the consumption time from the beginning of the practice process to the completion.

The ability to prevent collision with parts of fixed equipment through rotating worktables or cutting tools provides space for quick access to the geometric shape of parts is another influencing factor. Finally, through rotating the table or cutting equipment to adhere to the optimal cutting position and different chip loads, thereby improving the equipment life or life.

1.1 "5" for 5-axis machining

Five axis machining is a way of NC machining. The machining center we usually use is a three-axis machining center. The 3-axis refers to the x-axis, Y-axis and z-axis of the machining center. The five axis machining center adds two rotation axes to the three common linear axes x, y and Z, which are also called the fourth axis and the fifth axis. A. Two of the three shafts B and C have different motion modes in the vertical machine to meet the technical requirements of various products.

1.2 five main modes of five axis machine

There are many kinds of five axis machine tools for horizontal machining centers, mainly including the following five modes: one is the double rotary head mode, and the two rotation coordinates directly control the direction of the tool axis; 2. In the drooping rotary head mode, the two coordinate axes are at the top of the tool, but the rotation axis is not perpendicular to the linear axis; Third, double turntable mode, two rotation coordinates directly control the spatial rotation; 4. The two axes are on the workbench, but the rotation axis is not perpendicular to the axis; The fifth one is one swing and one rotation. There are two rotation coordinates, one on the tool and the other on the workpiece.

1.3 varieties of five axis CNC machine tools

There are several operations that can save you a lot of time and enhance your current program for the 5-axis CNC hand plate machining machine. These machines come in many varieties to meet the ever-increasing demands of the manufacturing industry. The common difference between 5-axis CNC hand plate machining machines lies in the arrangement of rotating shafts. They are divided into three different types, including head / head, table / table and table / head.

a. Head / head

The rotating shaft of this type of CNC hand plate machining machine is located at the head. They are made of 5-axis vertexes on a specific platform and moved by a fixed workbench to keep the workpiece in place. Therefore, you need not worry about the tool intervention of the spindle head of the machine tool. This makes the vertex sometimes move around specific parts, making the 5-axis CNC hand plate processing machine the best choice for consuming large parts. Due to their design, they usually have limited movement in the axis of rotation and tilt.

b. Table / head

In this type of machine setup, one rotating shaft is located in the turntable and the other in the head. The rotation axis is located at the head, and the range is limited, while the rotation axis is located in the table, and the range is not limited. Since the part is placed on the rotating shaft, this arrangement is limited by the number of items it can consume. One way in which the arrangement of this variant is slightly advantageous compared to the head / head type is that it can always rotate the part without worrying about reaching a specific limit.

c. Table / table

Here, all the rotating axes of the machine are located in the workbench, and the range of the rotating axes is also limited. The rotation axis range thereof is not limited. Compared with other types, this type of machine arrangement has the smallest working range. Others are equipped with clear motors to make them work quickly.

1.4 five axis machining ≠ five face machining

5-axis machining is very different from 5-face machining. Many people do not know this and mistakenly mistake 5-axis machining for 5-axis machining. The 5-axis machining has 5 axes of X, y, Z, a and B axes (or C). x. Y, Z and a, B axes (or C) constitute 5-axis linkage machining. Suitable for hook surface processing, special-shaped processing, hollow processing, punching, oblique hole and oblique cutting. 5-face machining is similar to 3-axis machining. Only five faces can be processed, and special processing, oblique holes, oblique angles, etc. are not allowed.
