Product characteristics
Wide applicability
Only one machine can cover most of the different models, different specifications of the cutter arbor, collet, and all can correspond to different tool stand and cutter arbor nut assembly.
High efficiency
The tool loading or unloading can be completed within 20 seconds, greatly shortening the tool changing time, improving production and efficiency and activation.
Safety
The machine only needs to select the touch screen function, and the loading and unloading can be completed at the touch of a button, without heavy tooling.
High precision
This machine controls the servo motor through the PLC program to accurately control the torque of the loading and unloading tools, ensure the stability of the loading tools, and avoid the difference in force values caused by different operators, loading and unloading tools, loading and unloading methods, etc.
Reduce production costs
The output torque of the machine is stable, which can greatly extend the service life of the tool and collet, and the cutter arbor and the tool have high matching accuracy, which can greatly reduce the production cost.
Our Advantages
Product Advantages
One: save both time and labour
Before using
Manual operation, time-consuming and laborious, need to use extension bar, tooling and other auxiliary tools.
After using
Loose button, fast completion, improve efficiency, save labor and time cost.
Two: Save worry and space
Before using
There are many kinds of loading and unloading tools, large quantity and difficult storage.
The tool stand is large and space-consuming.
After using
The appearance is consistent, simple and beautiful.
The tool stand is lightweight and easy to change with one hand.
Three: Safe and accurate
Before using
Manual operation is easy to lean forward and backward, resulting in safety risks.
The output torque is unstable, resulting in unstable process, often accompanied by damage to the nut jacket, and the cost is high.
After using
Click operation, there is false touch protection.
The torque is precise and controllable, the process is stable, and the cost is low.
