[specific embodiment]
The technical issues of in order to keep the application solved, technical solution and beneficial effect are more clearly understood, below in conjunction with
The application is further elaborated in accompanying drawings and embodiments.It should be appreciated that specific embodiment described herein is only used
To explain the application, it is not used to limit the application.
As shown in Figure 1 to Figure 3, the embodiment of the present application proposes to be applied to the mirror surface chromium-copper that hemisphere or semiellipsoid are processed
CNC processing technology is particularly suitable for worked copper public affairs, comprising the following steps:
S1, by blank clamping on the main shaft of CNC machine, specifically, the blank is cuboid；
S2 starts the main shaft, so that the main shaft is driven the blank rotation, cutter 10 is selected to carry out on the blank
Machining, makes the blank form pedestal 1 and processing department 2, and the processing department 2 is the mirror surface wheel of hemisphere or semiellipsoid
Exterior feature, the processing department 2 stretches out in the main surface of the pedestal 1 and the axis of the processing department 2 is overlapped with the main-shaft axis,
The process of the cutter 10 is while radially feeding to form the processing of the circumferential profile 4 of round or ellipse, along certainly
The processing department 2 is with a little extremely line on the vertex of the processing department 2 on 1 intersecting lens of pedestal outside the processing department 2
The projection line 3 on surface is processed.
It should be noted that the blank is rotated in combination with the cutter 10 in radial feeding, when described radial
When the amount of feeding is zero, the circumferential profile 4 processed is circle, when the short side and length that the radial amount of feeding is ellipse
When the difference on side, the circumferential profile 4 processed is ellipse, and certainly, the radial feed for being processed as the ellipse is specially
The cutter 10 completes feed twice during the main axis one week, and the feed period of feed twice is equal and transition is flat
Slow, the depth of cut is the radial amount of feeding.When the processing department 2 is hemispheroidal mirror surface profile, the circumferential profile 4
For circle, when the processing department 2 is the mirror surface profile of semiellipsoid, the circumferential profile 4 is ellipse.
Wherein, the cutter 10 preferentially uses ball cutter.The blank material is chromium-copper.
Required profile one-pass is completed the process with realizing, above-mentioned steps S1 and S2 are finishing, machined parameters
As follows: the revolving speed of the main shaft is 20000rpm~25000rpm, preferably 22000rpm；The feed type of the cutter 10 is half
Diameter is the circular arc feed of 1mm, feed engagement 0.036mm.
In above-mentioned technical proposal, the cutter 10 is processed along the projection line 3, and the rotation of the main shaft is cooperated to transport
It is dynamic, it can avoid in traditional processing very glibly by blank forming at the hemisphere or semiellipsoid profile of mirror surface due to more
It is secondary to be polished into ladder-like tool marks caused by tool backlash movement without further, uniform precision, and shorten the process-cycle.
In order to enable the feed more steady and smooth of the cutter 10, feed route when processing the processing department 2 include
It is tangential on the processing department 2 and the camber line of 1 intersecting lens of pedestal forms point of contact, the direction of feed at the point of contact and the blank
Rotation direction it is consistent.
In order to accurately distinguish the direction of copper public affairs, the main surface of the pedestal 1 is one jiao of rectangle for being processed into chamfering.
In conclusion the mirror surface chromium-copper CNC processing technology processed applied to hemisphere or semiellipsoid, by described
Cutter 10 is processed along setting path, cooperates the rotary motion of the main shaft, can very glibly by one-pass
By blank forming at the hemisphere or semiellipsoid profile of mirror surface, avoid in traditional processing due to repeatedly being caused into tool backlash movement
Ladder-like tool marks, without further polishing, uniform precision, and shorten the process-cycle.
It is the one or more embodiments provided in conjunction with particular content as described above, does not assert the specific reality of the application
It applies and is only limited to these instructions.It is all approximate with the present processes, structure etc., identical, or under the application concept thereof
It makes several technologies to deduce, or replacement all should be considered as the protection scope of the application.
