The Selection of Tool Holder System on CNC Machine
1. Introduction
As a key component of CNC machining, tool holder is an important part of tool system. Its quality and performance directly affect the cutting effect of machining quality and cost. Selecting a reasonable tool holder guarantees the machining quality and production efficiency, and plays an important role in the development and improvement of CNC machining technology. The tool holder system of CNC machine is a comprehensive system composed of tool changing system and tool library system, among which the choice of tool holder plays an important role.
2. Types of Tool Holder System
There are many types of tool holder systems, such as quick-change tool holders, constant-force tool holders, ISO style tool holders, CAT style tool holders, hydraulic stack tool holders and multitask tool holders. Quick-change toolholders can quickly and accurately change the tool, so it is widely used in CNC machining. They are rigid and accurate and can meet the higher requirements of CNC machining system. Constant-force toolholders are suitable for high-speed machining, small size, light weight and no loss of stability. ISO style toolholders are suitable for a variety of CNC machines with standard accessory specifications. CAT style toolholders are available for more powerful machines, but the cost is higher. Hydraulic stack toolholders are suitable for precision machining and high productivity, and are designed to work with other systems to provide maximum accuracy. Multitask toolholders are ideal for machining operations that require efficient production, which helps to save time and effort.
3. Selection Principles
The selection of tool holder system should take into account the influence factors of performance, cost and quality, and the selection of an appropriate tool holder system should meet the requirements of CNC machine machining accuracy and efficiency, while taking into account the cost of equipment and the cost of tool holders.
First of all, the tool holder system should have good rigidity, so that the tool is in a stable cutting position and the cutting edge is consistent with the machining surface. The selection should be based on the level of accuracy and surface quality. In terms of cost, it needs to take into account the cost of tool holders and its service life.
It is also important to consider the size of the tool holders. The size of the tool holders can be selected according to the type and size of the parts to be machined. It is necessary to select different types of tool holders according to the size and nature of the workpiece.
The tool library system of CNC machine should consider the size and number of tools used in CNC machining. It is necessary to select the appropriate tool library system according to the size and number of tools used. The tool library system should be able to provide different types of tools.
4. Safety considerations
The selection of tool holder system should also consider safety considerations. The safety of the tool holder system should be guaranteed, including the installation and maintenance of the tool holder system. Generally, the tool holder system should be installed by professional technicians to avoid accidents due to improper installation.
The tool holder system should be regularly inspected and maintained to ensure its safety and reliability. The inspection and maintenance should include checking the condition of the tool holder, the fastening screws and the bearings to ensure that all components of the tool holder system are in good condition.
In addition, the safety of machining personnel should also be taken into consideration. The tool holder system should be designed to minimize the danger of injury to personnel, such as flying tools during machining and other sharp objects.
5. Conclusion
The selection of appropriate tool holder system has a great influence on production efficiency and machining accuracy of CNC machine. The selection of appropriate tool is the key to realize efficient machining effect. The selection of tool holder system should take into account the safety of personnel and the cost of equipment. It is necessary to select the appropriate tool holder system according to the actual situation of CNC machining.
