The development numerical control technology is for overcome the human operators limitation, moreover he has completed this work truly. The numerical control engine bed is higher than the manual control ordinary engine bed precision, the components uniformity which produces is better, the production speed is quicker, moreover the long-term craft equipment cost is lower. The numerical control also causes them to use the manual control the senior use to be more widespread than. A numerical control engine bed may the automatic production very many type components, each components all be possible to have different and the complex processing. This design of automatic transmission is base on hydraulic cylinders, piston rod fork-led movement to promote the realization of sliding gear transmission and change the rotational speed, thus can achieve the main axle the big speed change scope. The engine bed main axle actuates to use the exchange frequency conversion velocity modulation electrical machinery.
