Embodiment Construction

[0029] The specific embodiment is described in detail as follows:

[0030] Such as figure 2 As shown, the relevant functional parameters of this embodiment are specifically as follows:

[0031] The width of the flange surface B = 7.5mm

[0032] Decontamination ring groove depth h=1mm

[0033] Decontamination ring groove width b=0.5×B=3.75mm

[0034] The diameter of the dedicated flushing channel d=3mm

[0035] The number of dedicated flushing channels is 4

[0036] Its working process is as figure 1 Shown; the process of cleaning compensation is:

[0037] Before the HSK tool holder 5 is clamped, there is a gap between the flange surface 1 of the tool holder and the end surface of the machine tool spindle 6 . When there is dirt or chips 7 in the range of the decontamination ring groove, as long as its thickness is less than 1 mm of the depth of the decontamination ring groove, it will not affect the reliable contact between the flange surface 1 of the HSK tool holder an...

Abstract

A HSK shank with compensation ability for fixing cutting tool to machine-tool features that a dirt-removing ring slot is made on its flange surface and several special flushing hole channels communicated with original high-pressure cooling liquid channel are made in the shank. Its advantages are high cleaning and abrasion compensating effect, and high load-bearing power.

Description

Technical field [0001] The invention belongs to the field of mechanical processing, in particular to an HSK tool handle with compensation capability, which is used for the connection between machine tools and tools, and is especially suitable for precision and high-speed processing machine tools. Background technique [0002] The performance of the tool holder has a direct impact on the machining accuracy, surface quality, efficiency, tool life, and processing costs. For a long time, BT (7:24 taper) tool holders have been widely used in various machine tools and achieved good results. However, due to structural limitations, this tool holder is not suitable for high-speed machining. Among the many developed toolholders suitable for high-speed machining, the HSK (abbreviation for Hollow Short Taper HohlSchaft Kegel in German) tool system developed in Germany is a relatively successful product and has been rapidly promoted and applied. [0003] The most basic feature of the H...
