When it comes to machining operations, choosing the right tool holder is critical for achieving optimal performance and productivity. One popular type of tool holder is the VDI static tool holder. In this guide to VDI static tool holders, we will discuss what they are, their benefits, factors to consider when choosing them, and common mistakes to avoid. Let’s get started!
What is a VDI Static Tool Holder?
A VDI static tool holder is a standardized tool holder that conforms to the VDI (Verband Deutscher Ingenieure) standard, which was developed by the German Engineering Association.
The tool holder is mounted on the turret of a lathe or turning center and holds cutting tools in place during machining operations.
There are different types of VDI static tool holders, including axial and radial tool holders, as well as tool holders with coolant-through capabilities.
Benefits of Using VDI Static Tool Holders
Using VDI static tool holders provides several benefits, including increased efficiency and productivity, enhanced precision and accuracy, reduced downtime and maintenance costs, and improved tool life and performance.
The standardized design allows for quick and easy tool changes, minimizing setup time and increasing machining productivity.
Additionally, the precise fit between the tool holder and the cutting tool results in improved accuracy and surface finish quality.
Different Types of VDI Static Tool Holders
There are several types of VDI static tool holders, including:
Axial Tool Holders
These VDI axial tool holders allow the cutting tool to be oriented parallel to the spindle axis.
Radial Tool Holders
These VDI radial tool holders allow the cutting tool to be oriented perpendicular to the spindle axis and can be used for facing or turning operations.
Angular Tool Holders
These tool holders allow the cutting tool to be oriented at an angle to the spindle axis, making them suitable for chamfering or drilling operations.
Multiple Tool Holders
These tool holders can hold multiple cutting tools, allowing for multiple operations to be performed without having to change tools.
VDI Boring Bar Tool Holders
These vdi boring tool holders are designed specifically for boring operations and can hold boring bars of various sizes.
VDI Cut-Off Tool Holders
These cut-off tool holders are designed for cut-off or parting operations and have a built-in mechanism for securely holding the cutting tool in place.
Overall, VDI static tool holders provide a versatile and reliable solution for holding cutting tools in place during machining operations.
What Are the Dimensions of a VDI Shank of VDI Static Tool Holder?
The dimensions of a VDI shank for a VDI static tool holder can vary depending on the size and type of the tool holder. However, in general, VDI shanks are standardized and follow specific guidelines.
There are available in all VDI shank sizes: 16mm, 20mm, 25mm, 30mm, 40mm, 50mm, 60mm & 80mm. And the most common sizes of VDI shanks for static tool holders are VDI 30, VDI 40, and VDI 50.
The dimensions of a VDI 30 shank typically include:
Shank diameter: 30mm
Length of shank: 80mm
Height of the dovetail: 15mm
Width of the dovetail: 25mm
Width of the flat surface: 20mm
The dimensions of a VDI 40 shank typically include:
Shank diameter: 40mm
Length of shank: 100mm
Height of the dovetail: 18mm
Width of the dovetail: 32mm
Width of the flat surface: 25mm
The dimensions of a VDI 50 shank typically include:
Shank diameter: 50mm
Length of shank: 120mm
Height of the dovetail: 22mm
Width of the dovetail: 40mm
Width of the flat surface: 32mm
It’s important to note that these dimensions may vary slightly between manufacturers and specific models of tool holders. It’s always best to consult the manufacturer’s specifications before purchasing a VDI static tool holder.
How to Choose VDI Static Tool Holders?
Here are some factors to consider when choosing the right VDI static tool holders:
Type of Operation
Consider the type of machining operation that will be performed (e.g. facing, turning, drilling, boring, etc.) and choose a tool holder that is specifically designed for that operation.
Tool Size
Ensure that the tool holder can accommodate the size of the cutting tool being used. Check the maximum tool diameter and length that can be held securely in the tool holder.
Accuracy
Look for tool holders with high precision and accuracy to ensure consistent and reliable performance.
Rigidity
Choose a machine tool holder with high rigidity to minimize vibration and improve the surface finish.
Material
Consider the material being machined and choose a tool holder made from a material that is compatible with it. For example, use carbide tool holders for high-speed machining of harder materials like steel or titanium.
Brand Reputation
Choose a reputable brand of VDI static tool holders to ensure quality and reliability.
Budget
Determine a budget for the tool holder, but also keep in mind that investing in a higher-quality tool holder can lead to better results and lower overall costs in the long run.
Compatibility
Ensure that the tool holder is compatible with the machine spindle interface and VDI quick change system in use.
Difference Between VDI And BMT Static Tool Holders
Here are some differences between VDI and BMT static tool holders:
VDI Static Tool Holders:
1. VDI stands for “Verein Deutscher Ingenieure” or Association of German Engineers.
2. VDI tool holders have a flange with radial slots that connect to the turret of the CNC machine.
3. They come in different sizes such as VDI 20, VDI 30, VDI 40, VDI 50, and VDI 60.
4. VDI tool holders are known for their ease of use and quick changeover system.
BMT Static Tool Holders:
1. BMT stands for “Base Mount Turret.”
2. BMT tool holders have a base that connects to the turret of the CNC machine with screws.
3. They come in different sizes such as BMT 45 and BMT 55.
4. BMT tool holders are known for their rigidity and stability during heavy-duty cutting operations.
In summary, both VDI and BMT block static have their own advantages and disadvantages. The choice between them will depend on the specific needs of the machining operation, such as the type of cutting tools used, the size of the machine, etc.
