Tips for selecting CNC tool holder?

December 14, 2021

CNC machining has more strict requirements for tool stiffness, accuracy, durability and dynamic balance performance. The selection of CNC tool holder should pay attention to the analysis of workpiece structure and processability, combined with the processing capacity of CNC machine tool, workpiece material and process content.

1、 For some simple tools that are used repeatedly for a long time and do not need to be assembled, it is appropriate to be equipped with an integral tool handle, so that the tool has good rigidity and low price;

2、 When machining multi variety and small batch parts with frequent changes in aperture and hole depth, modular tool handles should be selected to replace a large number of integral boring tool handles and reduce the processing cost;

3、 Manufacturing process. The exquisite process can make the equipment beautiful on the surface and complete in functions. If the process is not good, the equipment will be very rough and the price will naturally be reduced. Therefore, special attention should be paid to the manufacturing process when selecting.

4、 Manufacturer. When selecting equipment manufacturers, their scale, professional experience, sales and service must be very mature. At the same time, these are also factors affecting the price.

It is estimated that many people are not very clear about the value of the tool holder. Let's take a look at the tool handle in the TSG tool system. Its code (submitted for approval according to the 1990 national standard) consists of four parts. The meanings of each part are as follows:

JT represents tool handle type code.

45 - taper specification for taper shank.
Q32 - indicates the specification of the tool.
120 represents the working length of the tool handle.

The tools it represents are: 7:24 conical tool handle for automatic tool change machine tool (gb10944), the conical handle is No. 45, the front is spring clamp, the limit clamping diameter is 32mm, and the working length of tool handle (the diameter of the big end of the conical handle φ The distance from 57.15mm to the front end face of the spring collet) is 120mm.

If you want to reasonably select equipment, you must know the types of such equipment, their functions, differences and functions. In fact, there is no accurate regulation or comparison between the good and bad use of the product. You need to choose the type of equipment suitable for your use occasion and purpose according to your own needs. Of course, you should also pay attention to the accuracy of the product
