Quick Detail

Description

    This heat sink is based aluminum profile 6061 material to processing, first of all, we check the raw material dimension is fine or not, the second is that according to the drawing, use the CNC lathe machine to do the dimension, the third is that accroding to the drawing, the forth is that use the CNC to do exact dimension, the fifth is do anodizing surface treatment, and then inspection/packing. First inspection and patrol inspection are done in processing .

Note

Lathe processing is a part of mechanical processing. There are two main types of processing: one is to fix the turning tool and process the unformed workpiece during rotation; the other is to fix the workpiece and rotate the workpiece at high speed, and the turning tool (tool holder) )

Horizontal and vertical movement for precision machining.

The processing technology of CNC lathes is similar to that of ordinary lathes, but because CNC lathes are one-time clamping and continuous and automatic processing to complete all turning processes, the following aspects should be paid attention to.

• Reasonable choice of cutting amount: For high-efficiency metal cutting processing, the processed material, cutting tools, and cutting conditions are the three major elements. These determine the processing time, tool life and processing quality. The economical and effective machining method must be the reasonable choice of cutting conditions. The three elements of cutting conditions: cutting speed, feed and depth of cut directly cause tool damage. With the increase in cutting speed, the temperature of the tool tip will rise, which will cause mechanical, chemical, and thermal wear. Cutting speed increased by 20%, tool life will be reduced by 1/2. The relationship between the feed condition and the wear on the back of the tool occurs in a very small range. But the feed rate is large, the cutting temperature rises, and the back wear is large. It has less influence on the tool than cutting speed. Although the effect of cutting depth on the tool is not as large as the cutting speed and feed rate, when cutting at a small depth of cut, the material to be cut will produce a hardened layer, which will also affect the life of the tool. The user should choose the cutting speed to be used according to the processed material, hardness, cutting state, material type, feed amount, depth of cut, etc. The selection of the most suitable processing conditions is based on these factors. Regular, stable wear and longevity are the ideal conditions. However, in actual operations, the choice of tool life is related to tool wear, dimensional changes to be processed, surface quality, cutting noise, and processing heat. When determining the processing conditions, it is necessary to conduct research according to the actual situation. For difficult-to-process materials such as stainless steel and heat-resistant alloys, coolants or blades with good rigidity can be used.
• Choose a tool reasonably: (1) When roughing, choose a tool with high strength and good durability, so as to meet the requirements of large back-grabbing and large feed when roughing. (2) When finishing turning, choose high-precision and durable tools to ensure the requirements of machining accuracy. (3) In order to reduce the time of tool change and facilitate tool setting, machine-clamped knives and machine-clamped blades should be used as much as possible.
• Reasonable selection of fixtures: (1) Try to use general fixtures to clamp the workpiece and avoid using special fixtures; (2) The parts positioning datum overlaps to reduce positioning errors.
• Determine the processing route: The processing route is the movement track and direction of the tool relative to the part during the processing of the index-controlled machine tool. (1) It should be able to ensure the machining accuracy and surface roughness requirements; (2) The processing route should be shortened as much as possible to reduce the idle travel time of the tool.
• The relationship between the processing route and the machining allowance: Under the condition that the CNC lathe has not reached the popular use, the excessive allowance on the blank, especially the allowance containing the forging and casting hard skin layer, should be arranged on the ordinary lathe for processing. If you must use a CNC lathe for processing, you need to pay attention to the flexible arrangement of the program.
• Main points of fixture installation: The connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by a pull rod. The main points of the hydraulic chuck clamping are as follows: first use a moving hand to remove the nut on the hydraulic cylinder, remove the pull tube, and remove it from the back of the spindle Pull it out, and then use the moving hand to remove the chuck fixing screw to remove the chuck.
