What are the common types of Hardware Automatic Processing Equipment?

With the development of science and technology, the level of automation of the processing process continues to improve, greatly improving production efficiency.Hardware Automatic Assembly Equipment Successively developed to meet the requirements of different productivity levels of automated processing equipment, the main categories are as follows.

1.Automatic (semi-)automatic single machine
Divided into two categories of single-axis and multi-axis (full) automatic stand-alone machine.

It uses various forms of fully automatic (semi-) automatic stand-alone machine inherent unique performance to complete the processing of various parts and various processes, is a common method of automation of the machining process. Should be based on the process to be completed, the process and blank conditions to choose the type and specification of the machine; in addition, should be based on the number of varieties processed, the frequency of each batch of products and variety of changes to choose the control method. In the semi-automatic machine tools, sometimes you can consider adding automatic loading and unloading devices, tool magazines and tool changing mechanism, has been fully automatic processing.

2, special automatic machine tools
This type of machine tool is designed to complete a workpiece of a process and the design, the workpiece process analysis is often used as the basis for the design of the machine. Its structure is characterized by a relatively simple transmission system, fixtures and machine structure is closely related. In the design process, it is usually considered a part of the machine tool. The rigidity of the machine tool is generally better than that of a general-purpose machine tool. These machines are designed with fewer constraints and can fully take into account the requirements of automation.

3, combination machine tools
This type of machine tool consists of 70% to 90% of common parts, can shorten the design and manufacturing cycle, and can be partially or fully transformed. Combined machine tools are specially designed according to the specific processing object, can be processed according to the best technology program, high processing efficiency, high degree of automation; can realize the centralized processing of the workpiece, multi-surface, multi-tool processing, improve productivity; it can be a clamping. Multi-axis and multi-hole machining is conducive to ensuring positional accuracy and improving product quality; it can reduce the handling of workpieces between processes. Extensive use of common parts in the machine tool, simplifying maintenance and repair, reducing costs.

4, CNC machine tools
CNC machine tools are a new type of automated machine tools controlled by digital signals to control the action. Modern CNC machine tools are often controlled by a computer, called CNC. source program of the workpiece (including a variety of machine operations, process parameters and size control, etc.) can be directly entered into the computer with programming capabilities, the computer automatically programmed. Control the operation of the machine tool.

5. Machining Center (MC)
CNC machining center is a multi-process CNC machine tool with tool magazine and automatic tool changer. Workpiece once after clamping, can automatically complete more than two surface milling, boring, drilling, dumpling and other processes, and has a variety of tool change or tool selection function, so that the process is highly concentrated, significantly reduce the workpiece clamping caused by sequential processing of multiple machine tools, adjust the workpiece transfer between machine tools and workpiece waiting time, to avoid the processing errors caused by multiple clamping. This greatly improves productivity and automation.

6. Flexible Manufacturing Cell (FMC)
Generally composed of 1 to 3 CNC machine tools and material handling devices. The unit is equipped with tool storage, workpiece storage station and unit control system. The machine tool can automatically load and unload workpieces, change tools, check the machining accuracy of workpieces and tool wear; it can perform continuous processing for limited processes and is suitable for small and medium-sized batch production applications.

7.Automatic production line
A set of automatic machine tools and auxiliary equipment, by the workpiece transfer system and control system in the sequence of processes connected to the production system can automatically complete all or part of the product processing process, referred to as automated production line. In the working process of the automatic production line, the workpiece passes through each station automatically in a certain production rhythm according to the process sequence to complete the predetermined process. According to the process equipment used, the automatic production line can be divided into general machine tool automatic production line, special machine tool automatic production line, combined machine tool automatic production line and other types. The use of automated production lines can ensure product quality, reduce the labor intensity of workers and obtain higher productivity. The workpiece to be processed is usually fixed, or changes very little, so the automatic line is only suitable for mass production occasions.

8.Computer integrated manufacturing system
ComputerIntegratedManufacturingSystem (CIMS) is the highest level of automated manufacturing system, but this does not mean that CIMS is a fully automated manufacturing system. In fact, the level of automation in the current sense of CIMS is even lower than that of a flexible manufacturing system. The main focus of CIMS is the integration of information, not the automation of manufacturing process logistics. The main disadvantage of CIMS is that the system is very large and contains many elements that are difficult to implement completely in the enterprise. However, partial integration can be used to gradually achieve information and functional integration throughout the enterprise.
