When it comes to high-precision and stable tool handles, the first push is naturally the hydraulic tool handle, which can be easily locked with only one T-wrench. With high precision, convenient operation, diverse choices and other characteristics, the use of more and more occasions.

There are several main types:

① Ultra-fine type

This kind of tool handle is suitable for five-axis machining center, composite machining machine, etc., processing and mold processing, the outer diameter of the port is very thin, and the interference with the workpiece is well avoided. Taking into account high-speed machining, a maximum speed of 35,000 is achieved through the use of a high dynamic balanced oil pressure structure. Therefore, in the field of high-speed machining, hydraulic tool handles have also become a good choice.

② End feed type

The tool handle can be cooled in the center of the machine, allowing coolant to be sprayed from the front end of the tool handle. Because the hydraulic tool handle has an oil pressure chamber and other mechanisms inside, it is very difficult to make internal cold holes in the limited space inside the tool handle. The front end of the hydraulic tool handle of the hydraulic hydraulic pressure mechanism can be fed with oil, which can supply coolant or oil mist near the tip of the tool, thereby improving the life of the cutting tool.

③ Straight handle type

The handle can be used to achieve a longer extension length on the hydraulic handle, and can also be used to achieve the convenient operation of the hydraulic handle on other tool handles. It not only improves the versatility of high-precision hydraulic tool handle, but also the best choice of anti-interference.

④ Special hydraulic tool handle for fine processing

Meet the high precision and repeatability of the hydraulic tool handle for high-speed rotation, fine machining requirements.

Hydraulic tool handle common use questions and answers

Q1: What is the difference between hydraulic tool handle, strong tool handle and cold press tool handle?

A: Strong tool handle clamping force, high centering accuracy, suitable for strong cutting processing. The performance of the hydraulic tool handle is similar to that of the strong tool handle, but the accuracy is high, and the comprehensive accuracy of the good hydraulic tool handle can reach 0.002mm. Cold press shank and heat shrink shank may be the future trend, will replace the collet shank.

Q2: Does the hydraulic tool handle disassemble the tool for many times affect the clamping?

A: The hydraulic tool handle belongs to the high-precision tool handle, try to use a tool handle for each tool, and the ordinary tool handle should also be reduced as much as possible.

Q3: What if the hydraulic tool handle loosens the pressure bolt and the tool still cannot be taken out?

A: It may be blocked inside the handle. You can try to clean it by blowing air into the cold hole at the end of the handle with an air gun.

Q4: Advantages and disadvantages of hydraulic tool handle and thermal expansion tool handle?

A: Hydraulic tool handle is a very widely used tool handle, the clamping method of this tool handle is different from the traditional tool handle system, tightening only with a pressure bolt, when the bolt is tightened, it will push the piston seal block in the tool handle to produce a hydraulic oil pressure, the pressure is evenly transmitted from the circular direction to the steel expansion sleeve, and the expansion wall will clamp the tool. The accuracy of the hydraulic tool handle and the strength of the clamping force are good.

Q5: Why is the tap not equipped with hydraulic tool handle?

A: The hydraulic tool handle is a little oversize for the tap, the thread requirements are relatively not so high, and the chip removal space of the tap is small.

Q6: What is the difference between the tension nails for the hydraulic tool handle and the tension nails for the collet tool handle? Is it the same?

A: The difference between the nail is not that the tool handle is not the same, but the specification of the machine tool spindle, as long as it is the same equipment, the nail is the same specification.

Hydraulic tool handle use precautions

When the hydraulic tool handle is pressurized, the bolt needs to be completely tightened with a T-wrench, and the bolt will stop rotating at this time, and the hydraulic clamping force of the hydraulic tool handle plays the best when the bolt is completely tightened.

② When the hydraulic tool handle is installed with the cutting tool, the tool head should be close to the lower end of the hydraulic tool handle. If one end of the cutting tool is too short to be close to the bottom end of the hydraulic tool handle, the position of the cutting tool head can not be more than 8mm from the bottom end of the tool handle. (Otherwise, the inner diameter of the tool handle will shrink and be damaged and the tool handle will leak oil).

③ Before installing the knife to the hydraulic handle, the moisture and water (stained with oil) inside the handle should be removed. Because the inside of the handle is not cleaned up and the tool is installed directly, the liquid foreign matter inside the handle will lead to the loss of the cutting tool during processing. (Clean the inside of the handle before loading the cutter).

④ After the hydraulic hole is opened or pulled at will, the hydraulic oil will be lost, and the hydraulic tool handle will not be able to continue to be used and maintained.

⑤ Can not be installed rough cutting tools.

⑥ When the screw part of the handle is damaged or the hydraulic pressure cannot be processed normally and needs A/S maintenance, it is necessary to communicate with the manufacturer and cannot disassemble the handle by itself.
