In order to scrape a line along the turret axis that is one or two deep with tenth or two deep strokes with a CNC turning service tool that is one or two deep, it is necessary to use a CNC turn machining tool that is one or two deep. It is possible to transform a boring bar into something useful for aligning the cutting edge by rotating it 180 degrees. This month's column continues the discussion of how to maximize your productivity when cutting metal with a CNC lathe by providing some additional pointers and tricks: Working with plastics that are difficult to turn, you might want to experiment with turning off the constant cutting speed to see how it affects your results. Cutting speed can be manually controlled, which can aid in maintaining better control over the stringy chips that are produced during the cutting process. Some types of plastics can be difficult to machine unattended in a CNC lathe because of chip control issues. This is especially true when the lathe is operating at high speeds, which can be problematic in some cases. It is possible to increase the chip load by either slowing down the spindle or increasing the feed rate in order to thicken the chip material, both of which are options. Increasing the chip load is a good idea. It is possible that a seemingly insignificant task, such as CNC turning service off the coolant, can be extremely beneficial in terms of maintaining control over the chip in certain circumstances. One of the most common problems that users encounter when using a CNC lathe power chuck is getting the fine serration top jaws to fit properly in the chuck. As a result of the 1-millimeter serrations on the surface of the blank, it is very easy for one of the teeth to become misaligned, which can result in the centering of the blank becoming out of alignment. Additionally, it is difficult to measure three jaws and adjust them to the middle of their range of motion at the same time for a variety of reasons. I made special labels with the basic sizes engraved on them so that I wouldn't have to use a measuring tape. This saved me time and money. This enables me to quickly adjust the jaws to a range of diameters and hit all of the serrations with the same radius without having to think about it too much. Making your own engraving mill is simple and can be done for as little as $5, and it will only take a few minutes of your time. Before using the jaws, it is necessary to do some preliminary work. Before using the jaws, make sure that the part of the jaws that is attached to the labels has been thoroughly cleaned. After reinstalling the top jaws, it is recommended that you use a scratch brush to remove any fine jaw serrations that have formed on the jaws before proceeding with the rest of the procedure. It is possible to determine whether or not a tool is aligned with the scribed centerline by turning the workpiece upside down and looking at it through a magnifying glass. If you want to get the best results when performing bar pulling operations, it is preferable to use a spindle liner that is approximately the same size as your raw stock. The illustration depicts a straightforward spindle liner that is devoid of any complex features, as indicated by the arrows. Because flats are not included in the design of a boring bar by a tool manufacturer, the alignment of a boring bar with the machine axis and centerline may become more difficult on occasion. The setup bar is turned so that its end points in the direction of my vision, and I mark the bar with a marker to make it dark. Using a CNC milling tool, I scratch along the turret axis to create an indentation that is approximately one-tenth or two thou-tenths of an inch deeper than the surrounding material when I'm finished. When the turret's X-axis angle is aligned with the center of this line, it is considered to be a fairly accurate alignment. In the end, I was able to turn the small boring bar around and have something to use as a guide for aligning the cutting edge when CNC milling the boring bar as a result of the arrangement. Instead of using a mirror to see the tool from below, I use one to see it from above, which allows me to align it with the centerline that I have drawn on the paper.99% People Satisfying When See This CNC Working Process. Perfect Machines Technologycnclathing.com Remember to record the X-axis offset of your tool on the storage tube or directly onto it after you have finished using it and after it has been set up and tried out for the first time after you remove it from the lathe after you have finished using it. You will almost certainly save time the next time you use that particular tool as a result of your previous experience with that tool. The offset may not be perfect, but it is more likely that it is very close to being perfect than that it is not perfect. All of my external boring tools have this feature, and when they are not in use, they just butt up against the turret to keep them out of the way. In the event that I am forced to remove the holder from the machine as a result of this action, I will be in a position to maintain an accurate X offset after doing so. When re-creating the tool's configuration, it is critical for me to remember to account for the X offset offset. If the machine's X-axis travel is sufficient and the control allows it, it is possible to run the spindle in reverse to make a light test cut on the outside diameter of a part with an internal tool in order to set an accurate X offset without having to make and measure a bore. The offset on my machine is entered as a negative X value in order to account for the fact that the tool is in the negative X quadrant, as shown below. Due to the tool's location in the negative X quadrant, a negative X value is entered for the offset in order to accommodate this location. Consider carefully whether the control will accept a negative value while still carrying out the necessary offset calculations. Precision measurement of an outside diameter (OD) is far more straightforward than it is to accurately measure a bore or hole in the vast majority of cases, however. If you want to get the best results when performing bar pulling operations, it is preferable to use a spindle liner that is approximately the same size as your raw stock. Single spindle liners, which are designed to be dropped into the headstock, are one of the products that I have designed and developed. Standard pipe and tubing sizes that are widely available on the market are used to save money in order to maximize efficiency. When you receive a cutting order that does not meet the minimum requirements, you can use a waterjet or laser cutter to create a batch of disc blanks to complete the order. Organize this material and, the next time you require a special liner diameter, you will already have half of the work done for you. You will save both time and money as a result of this. Make use of a piece of tube to hold the discs in place while the rest of the assembly is being finished up. After that, you'll have a low-cost spindle liner for whatever oddball size you happen to be running on your machine in just two quick welds. |
