Abstract: A power and signal transmission device for a spindle of a machine tool is provided. The power and signal transmission device includes a spindle fixing portion, a shaft rotating portion, a power transmission component and a signal transmission component. The spindle fixing portion is provided with a power input end, a primary side power induction coil, a secondary side signal induction coil and at least one signal output end. The shaft rotating portion is provided with a joining end surface for bonding to a holder, a secondary side power induction coil and a primary side signal induction coil, and is rotatable with respect to the spindle fixing portion. The power transmission component transmits an electrical energy from the power input end. The signal transmission component transmits a holder signal to the signal output end. Each of the power and signal transmission components includes at least one elastic pogo pin.

Abstract: A five-axis space precision measurement fixture includes a body, screw holes to install first balls and second balls. The body has a first surface, a second surface, a third surface and an inclined surface located with respect to the third surface between the first surface and the second surface. The first surface and the second surface are parallel to each other and are located on opposite sides of the third surface. An included angle between the inclined surface and the third surface is 45 degree. The first balls are equal-spacing into columns and rows on the first surface, and each of the first balls is protruded from the first surface along a first direction. The second balls are also equal-spacing disposed on the inclined surface, and each of the second balls is protruded from the inclined surface along a second direction which is vertical to the first direction.

Abstract: A machining thermostatic control system and method of using the same are disclosed. The system comprises a detecting unit, a processing unit and at least a cooling unit. The detecting unit is used for detecting the temperature distribution of a workpiece. The processing unit is coupled to the detecting unit and is used for processing the temperature distribution for obtaining a position of maximum hot spot of the workpiece. The cooling unit comprises a head which is provided for discharging cooling fluid and a plurality of blades which are angle-adjustably mounted to the head. The blades are coupled to the processing unit and the angle of blades are controlled by the processing unit for enabling the cooling fluid to flow toward to the position of maximum hot spot position.
