Invention content

For prior art defect, the utility model provides a kind of numerical control polishing triangle polished die, and cooperation is existing The three-dimension numerical controlled polissoir of Siemens uses, and is mainly used for processing caliber high-precision planar optical elements, solves removal function Edge is unsmooth, and broken band occurs in optical element surface, and intermediate frequency error increases, the not high problem of machining accuracy.

In order to solve the above technical problems, the technical solution adopted in the utility model is：

The utility model provides a kind of numerical control polishing triangle polished die, including：Polished die matrix, buffer layer and polishing Layer；Wherein, polished die matrix upper end adheres to the buffer layer, and polishing layer is bonded above the buffer layer；The polished die Matrix and the buffer layer are circle, and the polishing layer is triangle；The polished die matrix is red copper, and the buffer layer is drip Blueness, the polishing layer are that the polishing with gum damps cloth.

A diameter of 20-50mm of polished die matrix upper end, polished die matrix lower end carries circular pit, along institute Circular pit is stated radially to open there are two notch.

The diameter of the buffer layer is consistent with the diameter of polished die matrix upper end, and the thickness of the buffer layer is 3- 5mm。

The polishing layer is the equilateral triangle for being inscribed in the buffer layer outer circle, and the polishing layer surface is provided with grid Slot.

The course of work of the utility model is：The utility model coordinates the existing three-dimension numerical controlled polissoir of Siemens to make When with, work, the circular pit of polished die matrix lower end and the stylus of numerical-control polishing equipment connect, the limit of stylus end Bolt is stuck in along the notch that the circular pit radially opens up, and the polishing damping cloth is contacted with workpiece, numerical-control polishing equipment Stylus does rotation and revolution motion, and polished die is driven to do rotation and revolution motion.A kind of numerical control polishing of the utility model is with three The removal function of angular polished die structure has the characteristics that edge removal efficiency is low, center is high and edge-smoothing.

The utility model has the advantages that：The utility model is thrown using round polished die matrix, round buffer layer and triangle The removal function edge removal efficiency of the structure of photosphere, structure is low, and center removal efficiency is high, solves optical elements of large caliber numerical control The edge effect of polishing reduces intermediate frequency error, improves machining accuracy and efficiency.
