How to use the magnetic tool holder

Use of lathe and tool holder:

The use of the center frame can improve the boring of the workpiece during the turning process, but because the workpiece is divided into two sections, there is a knife mark in the middle of the workpiece. For lathes that do not allow the attachment of the tool, the method of the tool holder should be used. The lathe and the tool holder are fixed on the saddle and are longitudinally moved together with the turning tool.

The lathe and the knife holder have two claws and three claws. When the lathe adopts the two-jaw tool holder, the cutting resistance of the turning tool to the workpiece makes the workpiece close to the two supports of the tool holder. When the lathe is actually used, the workpiece itself has a downward gravity, which causes the workpiece to bend naturally. Therefore, when turning, the workpiece often momentarily leaves the supporting claw due to centrifugal force and contacts the supporting claw to generate vibration. For lathes, it is best to use a three-jaw tool holder when turning the slender shaft. Because the three-supporting tool holder can be used to move the workpiece up, down, front and back, the turning is stable and vibration is not easy.

When using the tool holder, it must be noted that the supporting claws should be loosely supported on the workpiece. If it is too loose, it will not improve the rigidity. If it is too tight, it will affect the shape accuracy of the workpiece. ". During the lathe turning process, always check the tightness of the supporting claws and make necessary adjustments.

15.6 Inch POS

The POS Machine reads the cardholder's magnetic stripe information on the bank card through the card reader, the POS operator enters the transaction amount, the cardholder enters the personal identification information (ie password), and the POS sends this information through the UnionPay Center and uploads it. The card issuing bank system completes the online transaction, gives information on whether it is successful or not, and prints the corresponding bill. The application of POS realizes the online consumption of credit cards, debit cards and other bank cards, ensures the safety, speed and accuracy of transactions, avoids complicated labor such as manual inquiry of blacklists and pressing orders, and improves work efficiency.
