The power tool provides the user with the opportunity to completely machine one part in a single setup. However, the power tool itself does not provide the high height required for ultra-high speed machining such as grinding, polishing, engraving and small diameter drilling. Cutting speed. If it is a part, it is necessary to transfer from one “multi-function†lathe; to another machine or several machines for more high-speed machining; it means that the “multi-function†lathe foundation does not carry forward itself. It has the advantage of machining one workpiece in one setup. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
In order to optimize the machining function of the lathe; including ultra-high-speed machining; NSK USA has announced a shaft driven by compressed air supported by a non-touch air bearing; the intention is to supply up to 160,000 rpm for the power tool. Rotation speed.
Fortunately, the air bearing layout itself has the difference in rigidity and the resulting dissimilarity; not only does it not affect the machining accuracy; instead, it can make the tool slightly float; therefore, it improves the machining accuracy of the part; and also has the cutting force. Silkworm tomb β City > Toss. Even with regard to lower speed (60,000r/min) processing; the maximum cutting power consumed by the machine is only 40W. It can be used on machine spindles with a small pitch of 0. 5mm; it is usually used for medical equipment and electronics. Product parts processing.
The working principle of the air bearing is that the compressed air enters the power tool shaft supported by the air bearing; the two channels are divided into two; one channel is used to drive the power tool shaft; the other channel is used for the bearing seat to support the power tool shaft. Both the tool shaft and the air bearing housing are finely machined; the gap between the two is 0. 02mm.
The advantage of the air bearing is used for the power tool shaft; usually before the tool shaft rotates; the tool shaft is placed in a "floating" condition. That is to say; the air pressure must be applied primarily to the spin tool axis; Forming an air cushion between the bearing housing and the air cushion. The air cushion is formed by opening a manual air valve or by turning on a solenoid air valve according to the programmed procedure; controlling the air pressure required in the operation.
