Problems solved by technology

It needs to cut the front chamfer first, then adjust the position of the processed sheet, and then cut the facade, so it needs to be processed twice, which causes the defects of difficult secondary positioning, poor cutting accuracy, and increases the cost of the tool and reduce work efficiency

Embodiment Construction

[0008] With reference to the accompanying drawings, the design of the blade of the present invention calculates the length of the Y direction edge of the second cutting edge BC respectively according to the formula, d2=L-BctgA+D, wherein:

[0009] A: The angle between the first cutting edge AB and the center line O;

[0010] B: The width of the chamfer of the cut piece along the direction perpendicular to the centerline of the tool;

[0011] L: the thickness of the cut piece;

[0012] D: The depth of the tool piercing into the protective film (that is, the depth in the Y direction downward from the bottom plane of the cutting piece, ranging from 0.05 to 0.1mm).

[0013] For example: when the thickness L of the piece to be cut is 0.5mm, the width B of the chamfer of the piece to be cut along the direction perpendicular to the centerline of the tool is 0.1mm, and the angle A between the first cutting edge (upper section) AB and the centerline O is 45°, and when the depth D of ...

Abstract

The invention relates to a cutting tool of CNC for machining mobile phone lens. The main cutting blade of the cutting tool at least contains a first cutting blade AB and a second cutting blade BC. The first cutting blade AB has an inclination with cutting tool center line O. The angle of inclination A is same as chamfer F. The blade length of second cutting blade BC along Y direction, inclination A, width of chamfer F along X direction, thickness L of cutting material, and technical parameter D has the relational expression of D2=L-BctgA+D. The advantages of the cutting tool are that it shortens the process time, and improves cutting accuracy, etc.

Description

technical field [0001] The invention relates to a cutter on a CNC (numerical control machine tool) for processing mobile phone lenses, in particular to a one-time forming cutter for processing mobile phone lenses that is suitable for special shape requirements. technical background [0002] At present, the CNC tools used in the mobile phone lens cutting industry are usually two-time molding cutting the facade or chamfering on the upper part of the facade. It needs to cut the front chamfer first, then adjust the position of the processed sheet, and then cut the facade, so it needs to be processed twice, which causes the defects of difficult secondary positioning, poor cutting accuracy, and increases the cost of the tool and reduce work efficiency. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, after repeated experiments by technicians, proofreading and repeated adjustment of processing parameters, a one-time molding tool fo...
