Tool with micro-feed function and method thereof

The invention relates to a tool with a micro-feed function, which can be used in ultra-precision machining to improve the micro-feed resolution of a machine tool and realize ultrathin cutting and high-precision dimension machining on an ultra-precision machine tool. The tool with the micro-feed function is characterized in that a purpose-made cylinder body is installed on a tool rest, and the required micro-feed is realized through the elastic deformation of the lower end surface of the cylinder under the oil pressure of the cylinder body. By accurately controlling oil pressure inside the cylinder body, the accurate micro-feed can be obtained to realize the corresponding precision feed. The tool with the micro-feed function integrates a tool bar and a cylinder body with the micro-feed function into a whole, is free of intermediate driving parts, has the characteristics of compact structure, excellent input-output linearity, high rigidity, large stroke, high resolution, low production cost ...

Method for testing performance of HSK tool system and its device

Multipurpose vertical device for testing comprehensive properties of HSK tool system

The invention discloses a multipurpose vertical device for testing the comprehensive properties of an HSK tool system and relates to the technical field of machining tool testing. The device comprises a base (1), a vertical box body (2), a spindle mechanism, an HSK knife handle seat (24), a knife handle clamping structure, a knife handle assembling and disassembling mechanism, a clamping force adjustment mechanism, a clamping force measurement device and a spindle locking device.
