When the operator begins to process CNC parts, the feed speed should be adjusted to a very low value. This is because the feed speed affects the accuracy of the processing. The operator needs to keep their attention on the energy when they are performing rapid positioning, tool drop, and tool feeding all in a single section. The hand needs to be positioned so that it is pressing the intermittent key. In the event that there is a problem, the process will be stopped immediately; in the meantime, pay attention to the direction in which the tool is moving. Add coolant or cool air to the tool and the workpiece at the same time in order to ensure safe feeding, and then gradually increase the feed rate to a level that is suitable for the task at hand.
When beginning rough machining, the workpiece should not be located an excessive distance from the control panel. When an unusual occurrence occurs, it is important to put a stop to it and investigate it as soon as possible. Once the rough has been opened, you should pull the watch once more to ensure that the workpiece has not become dislodged. It is necessary to recalibrate and touch the number if it becomes necessary to do so. In order to achieve the best possible effect from the processing, the processing parameters are continuously optimized throughout the processing process.
After the workpiece has been processed, it needs to be measured to determine whether or not its primary standard values are in accordance with the requirements of the drawing. In the event that there is a problem, you should immediately inform the team leader or the programmer so that they can check it out and deal with it. It is possible to remove it after it has successfully passed the self-inspection, but before doing so, it must first be sent to the inspector for a special inspection. The following is a list of common types of CNC part processing.
It is necessary to use the center drill for positioning purposes prior to drilling holes on the machining center. After that, a drill bit that is 0. 5 to 2 millimeters smaller than the drawing standard is used to drill the hole, and the appropriate drill bit is used for finishing. Reaming out the processIt is necessary to use the center drill to locate first, then use a drill bit that is 0. 5–0. 3mm smaller than the drawing standard to drill holes, and finally use the reamer to ream the holes in the workpiece. All of these steps are necessary for reaming the workpiece. When reaming, it is important to pay attention to maintain the spindle speed at 70 degrees within 180 revolutions per minute.
routine administrative tasksIn order to perform boring processing on the workpiece, first locate it with the center drill, then use a drill bit that is half a millimeter smaller than the drawing standard, and finally use a rough boring tool to process it to a machining allowance of only about 0. 3 millimeters on one side. All of these steps should be performed in the order listed. When performing fine boring, always make sure to use a tool that has been pre-adjusted for standard fine boring, and the allowance for the following fine boring should never be less than 0. 1mm.
Before beginning the DNC numerical control processing, the workpiece needs to be clamped, and the zero position and parameters need to be set. Direct numerical control operations can then be carried out. Launch the processing program that will be transferred into the computer so that you can check it, then wait for the computer to enter the DNC state before entering the file name of the processing program that should be used. When you operate the machine tool by simultaneously pressing the TAPE key and the program start key, the machine tool controller will display the glowing LSK words. To begin the data transfer processing for the Nylon CNC Machining DNC, press the Enter key on the computer.
The clamping of the workpiece is another issue that arises during the processing of CNC parts, and it is one that requires careful consideration. How do you go about clamping the workpiece during the processing step?Before the workpiece is clamped, all surfaces need to be cleaned to remove oil, iron filings, and dust. Then, using a file, the burrs that are on the surface of the workpiece need to be removed.
It is necessary to use a grinder to grind the high-speed rail that is used for clamping in order to make it lubricated and smooth. Both the code iron and the nut need to CNC milling service be sturdy and capable of firmly clamping the workpiece. Some small workpieces that are difficult to clamp can be directly clamped on the vise; the machine table should be clean and free from iron filings, dust, and oil; the horn is typically positioned toward the front of the machine; andIt is appropriate to position it in each of the workpiece's four corners. When working with workpieces that have a span that is too large, it is necessary to add horns in the center that are of equal height. Use calipers to determine whether the length, width, and height of the workpiece meet the requirements outlined in the drawing standard.
When clamping the workpiece in accordance with the clamping and placement method of the programming work instruction, it is necessary to think about avoiding the processing part and the situation in which the cutter head may hit the fixture while it is being processed. This is because both of these things can occur while the workpiece is being processed. Following the placement of the workpiece on the horn, the datum surface of the workpiece should be pulled in accordance with the specifications of the drawing, and the workpiece's straightness, which has been ground on all six sides, should be examined.
Pull the table once more to ensure that the error threshold has not been breached after the clamping has been done, and then tighten the nut after you have pulled the workpiece. This is necessary because the clamping is not robust enough to prevent the workpiece from being moved while it is being processed. If you are looking for a professional CNC processing manufacturer, Xiaobian recommends that you make a comprehensive decision based on a number of criteria, including the qualification and strength of the manufacturer, the customer case of the manufacturer, the manufacturer's technical level, the manufacturer's reputation and reputation, and the quality of the manufacturer's after-sales service.
When it comes to processing precision parts for hardware, the material that is used most frequently is aluminum alloy. In the construction industry, aluminum alloy is the non-ferrous metal structural material that is used the most frequently. It has found widespread application in the fields of aviation, aerospace, automobile manufacturing, machinery production, shipbuilding, and the chemical industry. Because of the rapidly accelerating growth of the industrial economy, there has been a rise in demand for structural parts made of welded aluminum alloy, which has led to an increase in the amount of research conducted on the weldability of aluminum alloys. The aluminum alloys of the six-series 6061 and the seven-series 7075 are the ones that are utilized the vast majority of the time. Applications that require high oxidation resistance and corrosion resistance are good candidates for the use of the aluminum alloy 6061. Good usability and easy coating processability; the 7075 aluminum alloy also belongs to the aviation series; it is an aluminum-magnesium-zinc-copper alloy; it is a heat-treatable alloy; and it is a super-hard aluminum alloy that belongs to that category and has good wear resistance. It also has excellent weldability, but its resistance to corrosion is quite low.
The electrolytic oxidation process that is referred to as anodization of aluminum is a procedure in which the surface of aluminum and aluminum alloys is typically transformed into an oxide film. This film possesses properties that are protective, decorative, and some have other functional applications as well. The formation of an anodized film is the only aspect of the process that is considered to be part of the anodization of aluminum according to this definition.
