Analysis of the steps of loading, changing and selecting a knife in a small machining center

The tool magazine is equally important to the machining center, and all types of machining operations are performed by the tool magazine. The tool magazine is generally divided into three types, disc type, bucket type and chain type tool magazine. The tool change and tool magazine selection of the small machining center can determine the required number of tools according to the process analysis result of the workpiece to be machined. Usually, the capacity of the tool magazine is determined by the number of tools required for one part in one setup, because another When machining a part, it is necessary to rearrange the tools of the small machining center, otherwise the tool management is complicated and error-prone.

 


 

The small five-axis machining center is a very popular machine tool. It is mainly used in college maker studios, scientific research units to process small parts and college teaching. Its biggest feature is high cost performance, good stability, high reliability and processing. High precision. Small machining centers can process some flat, curved, and beveled parts. The biggest disadvantage of the small five machining center is that there are certain constraints on the dimensions of the machined parts.

 

From the statistical data, the small machining center uses a knife magazine of about 20 knives, and the horizontal machining center uses a knife magazine of about 40 knives. Of course, it must be finalized according to actual needs. Machining center machines for flexible manufacturing units (fmc) or flexible manufacturing systems (fms), whose tool magazine capacity should be selected for large-capacity tool magazines and even for the exchange of tool magazines.

 

Steps for loading, changing, and selecting a small machining center

 

The machining of the small machining center is very simple. Record the type of tool type and the corresponding tool holder number. You can select any tool holder in the magazine to load the tool.

 

When changing the knife, it is divided into the following three cases.

 

1. The tool on the spindle of the machining center is an optional tool holder. The tool to be changed is a fixed tool holder.

 

Steps: Tool magazine → Select tool → Change tool position → Robot remove tool → Load spindle, the tool removed from the spindle is sent to the empty tool position.

 

2. The tool on the spindle of the small machining center is placed in a fixed tool holder, and the tool to be changed is an optional or fixed tool holder.

 

Tool change procedure: tool magazine → tool selection → tool change position → robot remove tool → load spindle, when the tool removed from the spindle is sent to the tool magazine, the tool magazine should be rotated to the position of the receiving tool.

 

3. The tool on the spindle and the tool to be changed are optional tool holders.

 

The tool change procedure is as above, and the tool with the spindle removed is loaded into the tool holder of the tool to be changed.

 

There are also three ways to select a small machining center:

 

1. Select the knives in sequence, install the knives in the turret according to the order of use of the knives, and select them one by one according to the order, and then put them back to the original position after use.

 

2. Select the knife at random, encode the tool holder, and place the corresponding tool into the specified tool holder. At the same time of programming, mark the tool holder code with the address T.

 

3. Memory selection knife, in the memory of the machining center, the tool number and the tool position and the tool holder number are recorded. When the tool storage address is changed, the machining center memory is also changed, and the tool magazine in the small machining center is changed. The position detection device is installed, and the cutter can be taken out and returned at will.
