In the field of high-precision machining, the hydraulic collet in the hydraulic toolholder is extremely critical, and its performance is directly related to the machining accuracy, efficiency and cost. In this article, let's take a look at the new BRIGHT-TOOLS hydraulic collet.
Hydraulic Collet Working Principle
By applying pressure through the hydraulic system, the inner wall of the collet produces uniform radial contraction or expansion, so as to tightly hold or loosen the tool to achieve reliable clamping and positioning.
Problems Generally Encountered with Hydraulic Collet
Insufficient clamping force leading to tool drop: Hydraulic collets sometimes have insufficient clamping force, resulting in tool loosening and falling off during the machining process, which not only seriously affects the machining process, but also may lead to tool damage, workpiece scrap and other problems.
Unstable precision and large deviation: the accuracy of some of the hydraulic collet performance is poor, there will be precision fluctuations in use, it is difficult to ensure the consistency of machining, resulting in substandard machining accuracy of the workpiece, unable to meet the demand for high-precision machining.
Poor water-stopping ability: some hydraulic cartridges are unable to achieve water outlet from the centre or have low pressure-bearing capacity, resulting in poor coolant supply, poor tool heat dissipation, accelerated wear, and often interrupted machining, which not only increases tool loss but also reduces work efficiency.
BRIGHT-TOOLS hydraulic collet new upgrade
1) High precision:slit grooving technology, when the outer circle of the collet is subjected to external force, its inner hole can achieve extremely uniform deformation, which ensures the ultra-stable state of precision, and the radial runout precision can be accurately controlled within 3μm.
(2) High clamping force: the design of plum blossom end face, this unique structure makes the collet not only can be clamped by the side wall, but also the end face can be contracted inward, so that the collet can form a greater clamping force; 
(3) With the characteristics of the centre of the water outlet: it can withstand the coolant pressure of 80bar; in order to achieve a better effect of the centre of the water outlet, a sealing ring has been added to the port of the collet;

1) Hydraulic collets - centre of water outlet ) Hydraulic Collet - Centre Water Out:
2) Hydraulic Collet - Face Water Out:
Ginger CNC has not only the centre water out standard collet, but also the face water out collet. When encountered with non-centre through-hole tools, it can discharge water from the end face, straight to the machining part, cooling down quickly to ensure the smooth progress of machining.
