How about the central screw in the CNC lathe? Or an ordinary side screw!
Sen's advantage: cheap. Disadvantages: in addition to cheap. 6136 a little more than 5. Buy 36, buy 40, not much money. I don't know how high the power of the 36 spindle is, anyway, 40 is 5.5KW. Variable frequency spindle is more sensitive to power. Low speed, the output force is not enough, and sometimes will stop the spindle. Now that you choose big Sen, you value his merits. Well, I won't comment either. The design of the middle screw leads to the inconvenience of cutting, and no improvement has been found in the design process. Goods than three in order to find quality products, the boss, you may as well more Internet, check different machine tool factory products, learn more to earn more. I wanted to go on, but when I saw the eggs, I was really embarrassed to go on.
It depends on where you are. The quality, the price and the service of each product are different. Near Hangzhou, I can give you some advice.
Structurally, the center screw must be stable. Without doubt.To tell the truth, NC cars are too many brands, and not so good brand, it is better to see its quality can not do.The lathe is good. Look at the key points. Spindle, wire guide, motor, and the work of its own bed.Table spindle, guide rail, screw rod, motor, high performance price ratio.Japanese spindle, wire rod, guide rail and motor are of good quality, but they are expensive. (people do things too much consideration of the cost, resulting in quality can not keep up. Hey
