The article illustrates how, taking into account the achievements in science and technology, the kinematic chain from the driving force (engine) to the executive body (spindle) was shortened and became the shortest in the form of a motor-spindle. On the examples of lathes and milling machines, places of possible limitation of spindle rotation frequencies are highlighted. A self-acting motor-spindle, which has rotary and translational motion, is proposed.

In order to obtain the methods of assessing the quality of the functioning of the motor transport company, it is necessary to develop a methodology for quantitative evaluation of this quality. This methodology should be based on mathematical models of the quality of operations of the motor transport firm.
For purposeful formation of quality, the paper proposes an adequate method of analysis of this quality. At the same time, a method of evaluating the quality of the functioning of the automobile enterprise, evaluating the quality of the decisions taken to improve this property, and forecasting the expected quality of the functioning have been developed.

The study of the formation process of the operation quality of a transport firm is the most topical, since this process significantly determines the dynamics of its evolution. The paper presents the concept of the product and service quality, describes the difference between the service and the product, as well as a step-by-step scheme of quality development. The history of quality management development is also discussed on the example of three leading regions of the world: USA, Japan and Western Europe.
Methods for assessing the quality of products and services have been established, which are somewhat different from each other and are of great importance for assessing the activities of a transport enterprise.

History of gradual increase of elements of artificial intelligence is resulted in the process of creative thought at creation of on principle new structures and charts of clamping cartridges on the example of cangovykh. Thinking process on on the lasts of peat-time of application of artificial intelligence presented as a binary koda and waves of frequency impulses, reminding cerebration.

The original design of a cavitator is a volute (snail) with a tangential inlet connected to the pump and an axial outlet which is attached to the body in the form of a cylindrical tube, which ends with a braking device and a central hole connected to inlet of the pump.
Proposal: 1) to equip cavitator with axial gas extractors in the volute (snail) and at the output from the body, 2) exclude the snail (volute) from the construction and control the interaction of flows by dividing stream leaving the pump into two parts and then merge them in the camera in front of body, 3) organize an axial jet in body with the required structure by using ring nozzles, 4) reduce a vortex component of the current by installing a second straightening snail (scroll) before the body, 5) design the pump as an active generator of elastic vibrations of useful frequencies while maintaining its primary function; – separate it with antivibration bushing.
