CNC lathe spindle box is a key component of the CNC lathe system, and its dynamic characteristics are the main factor affecting the machining accuracy and processing efficiency of machine tools. In this paper, CK61125 CNC lathe spindle box model was established by simplifying its structure. Then modal analysis of the spindle box was done and extended to 6-order modes with the platform of co-simulation environment in ANSYS Workbench, and the natural frequencies and vibration modes for lathe spindle box were obtained. The weak links in the spindle box were found, and the improvement schemes are proposed. Finally the lathe spindle box was improved, the modal analysis of the spindle box was made again, and the results showed that the lathe spindle box dynamic performance was improved. All of these results are beneficial for optimization and re-design of the lathe spindle box so that it has better dynamic performance.

With the rapid development of science and technology, Lathe will be sure to develop in the direction of high speed, high precision and high stability as the most basic and important production equipment in industry. The spindle is the one of important component in the lathe, of which static and dynamic characteristics is directly related to the machining precision and machining stability, and the performance of spindle system directly affects the overall machine specifications. Through the analysis of the characteristics of spindle, the ways and means of the spindle analysis are studied. For the requirements of static and dynamic characteristics analysis in the process of spindle design on high-precise CNC lathes hydrostatic, direct-drive spindle motor mode is used. Three-supporting structure is adapted in the layout of spindle bearing in order to improve the accuracy and stability of the spindle drive. The rolling bearing is used in auxiliary support, the front and rear radial bearing is used in master hydrostatic bearing. Thrust bearings are located on both sides of the former type of radial bearing to complete the selection of the spindle material and the design of the structural primary dimensions. It is meaningful to improve the specifications of CNC lathes, guide the design, generation and modification of the high precise CNC lathe and enhance static dynamic characteristics of the spindle and improve accuracy and stability of the machine tool processing.

In the paper the problem of reasons elucidation in the matter of lathe instability at groove cross turning and boring is solved. As a tool for the analysis of a structure state there are used potentialities of modal monitoring, and in particular, a correlation of modal parameters, sets of proper characteristics of an elastic system (self-frequencies, modal coefficients damping and own forms of vibrations) of lathes designs with the state of bearings in spindle units. The application of a modal approach to the evaluation of a lathe design state or an elastic system is a new section in a dynamic analysis and may be called modal diagnostics. From the analysis of the modal parameter values of a lathe one traces their tie with the lathe design characteristics, and in particular, with the existence of sever rigidity anisotropy of a spindle unit front bearing and also with its insufficient tightness. Reasoning from the information mentioned of the modal parameters connection with the rigidity of a spindle unit front bearing and a state of bearing design the authors draw a conclusion of the technological state of a spindle unit design. In such a way, by the example of the design of two lathes in the paper there is shown a possibility of transition from experimental frequency characteristics through a procedure of modal diagnostics to the evaluation of the technological state of a spindle unit.

A conventional manual lathe electric motor drives the multi-stage gearbox transmitting torque to the spindle so that the workpiece makes contact with the machine tool at a given speed. The cutting speed is proportional to both the diameter of the workpiece and the spindle speed, however, the increments in spindle speed are limited. Manual lathe machines cannot be regulated at the optimum cutting speeds for all diameters. An innovative modernization of the main driveline of a TSB16 manual lathe is proposed in this paper, allowing for a cost-effective system for digital control of spindle speeds using an inverter. The inverter is controlled using an 8-bit AO (analog output) converter with special software developed with Visual Basic. The results of the analysis and various test runs with this new system for automated control of spindle rotation, showed that the required cutting speed can be achieved for any workpiece diameter. The deviation of cutting-speed of the upgraded system for any turning diameter is greatly reduced in comparison with the deviation of cutting-speed of a manual lathe. Finally, tests on this versatile system demonstrated a cost-effective method for modernizing the drive system of conventional lathe machines.

Verktygsmaskiner möjliggör tillverkning av materiekroppar med olika form. Svarvar är de vanligaste maskinerna för att bearbeta runda detaljer. Man kan säga att en svarvspindeln möjliggör hela skärprocessen och att den därför är den viktigaste komponenten i en svarv. En svarvaxel, eller en spindel, bearbetar det roterande ämnet med ett stationärt skärverktyg, och materialet tas bort vid skärverktygets kontakt med ämnet.Det här arbetet syftar till att konstruera en spindel som uppfyller en given kravspecifikation. Specifikationen innehåller prestandakrav, som rotationshastighet och kraft, geometri och dimensionskrav, som storlek och håldiameter, samt vilka komponenttyper som ska användas, som t.ex. motorn.I enlighet medprestandakravet definieras maximalt lastscenario. Med givna svarvningsparametrar beräknas skärkraften på materialet vid dess kontakt med skärverktyget. En inbyggd motor som är tillräckligt kraftfull och uppfyller hastighets- och effektkraven väljs och en preliminär konstruktion skapas med valda lager, lagerordningar och axelmaterial.Beteendet av den preliminära spindelkonstruktionen, under påverkan av skärkrafter och rotation analyseras statiskt och dynamiskt med hjälp av FEM och analytiska modeller. Inom ett givet område optimeras avståndet mellan lagren, vilka utgör spindelns stöd.Genom verifikation och optimering av den preliminära konstruktionen skapas den slutliga detaljkonstruktionen. Slutkonstruktionen innefattar alla nödvändiga detaljer och viktiga krav beaktas och balanseras, som att vara tillverkningsbar och monterbar, tätningssystem, ett system för hastighetsmätning och lägesmätning, kabelvägar och andra nödvändiga punkter. I slutänden konstrueras en spindel som uppfyller den definierade kravspecifikationen.
Machine tools enable the industry to shape almost any material by a variety of methods. Lathes are one of the most common machines to cut circular parts with precision and accuracy. And the spindle of a lathe can be entitled as the most critical mechanical component which makes the cutting process possible. A lathe spindle rotates the workpiece to be cut against a stationary rigid cutting tool, therefore removing material through the contact edge. In this thesis, a spindle is aimed to be designed which complies with a set of specifications defined. These specifications consists of performance requirements such as speed and power, dimensional constraints for space and bore diameter, and component types which must be used, such as for the motor.Based on the performance requirements, a maximum loading case with cutting parameters is defined. With these cutting parameters, cutting forces acting to the material from at the contact point with the cutting tool are calculated. A built-in motor with sufficient power and speed specifications is selected based on the maximum cutting forces and speed requirements. A preliminary design is made up by selecting bearings, bearing arrangements and shaft material.With static and dynamic analysis conducted on the preliminary design through analytical models and FEM, the behavior of the spindle is investigated separately under the cutting forces and during the rotation. Within an allowable range, optimization is made on the bearing span distances which are the support locations for the spindle.Following the verification and optimization of the preliminary design, the final detail design of the spindle is made. The final design includes the design of all the necessary parts, by taking the manufacturability, assemblability, sealing design, a system for speed and position measurements, cable paths and more necessary points into account. Ultimately, a spindle which meets the requirements and specifications successfully is designed as the expected outcome of this thesis.

The Lauxaniidae are one of the largest families of acalyptrate Diptera (series Schizophora) and are distributed in all the major zoogeographical regions of the world. Early taxonomic work on the family began in Europe and some notable studies were done during the late 19th and early 20th centuries. Since then few significant revisions on regional faunas have been undertaken. There are 142 recognized genera and about 1550 described species in the world fauna of Lauxaniidae as compiled from available references (Shewell 1965, 1977, 1986, 1987; Stuckenberg 1971a; Miller 1977a,c, 1980; Papp 1984a, 1984b; Yarom 1986; Evenhuis and Okadome 1989; Hirashima 1989; Broadhead 1989; Sasakawa and Pong 1990; Colless and McAlpine 1991; Sasakawa 1992; Silva, pers. comm.). The family has been divided into two subfamilies distinguished principally by the costal form: Homoneurinae Stuckenberg 1971 having a homoneuriform costa (its spinules stop abruptly at or just before the apex of R4 + 5) and Lauxaniinae Shewell 1977 with a sapromyziform costa (the spinules stop well before the apex of R4+ 5).

This paper discusses the modeling and analysis of an example medium speed medium precision lathe spindle. This and few other similar topics have been assigned as term projects in an introductory senior undergraduate/graduate level finite element analysis course taught at Kettering University. The experiences and the general feedback from the students of the class show satisfactory organization of the course material that includes modeling and analysis of real life examples. With reference to the specific topic on design of machine tool spindles, it is not a new area, however, it is generally taught at the graduate and research levels. Use of modern computational tools to perform iterative design and analysis calculations of such spindles make the senior undergraduate and/or graduate master students aware of the implications of modeling a real life system using the 1D and 3D finite beam elements and to validate those results by a CAE tool. Final course projects such as this serve as a good learning tool to the graduating engineers. Sample results obtained from various CAE tools such as UG-NX 7.5 are presented in the paper and discussed.

A new CNC lathe with a pipe frame bed has been developed. One requested improvement for machine tools is their downsizing by minimizing the number of mechanical parts. Some researchers aim to construct a desktop factory. This trend has been attracting a lot of attention lately in the industrial field. When a machine tool bed is designed using castings and/or welded steel plate structures to comply with this request, it is difficult to ensure space for chip evacuation because of the space limitations of solid body components. This led us to develop another type of structure for machine tools. A pipe frame bed has the ability to solve this problem. As represented by bridge trusses and flexible space structures, truss structures are traditional and fundamental in their design. This structure is expected to have enough space between the truss bars to solve the space problem. However, rigidity is the most significant issue for machine tools. Therefore, the desired rigidity is ensured by the use of diagonal braces. Based on this design concept, a CNC lathe whose frame consists of pipes, joints, and diagonal braces has been developed with enough rigidity and space utility for chip evacuation. From the viewpoint of machine tool usage, the rigidity and stable dynamic characteristics of the structure must be obtained. Then, real-time vibration control theory is applied to the relative displacement between the tool post and the spindle. Active vibration control is used to suppress specific relative vibration modes. In this paper, the effects of vibration control are evaluated by comparing the relative vibratory motion between the tool post and the spindle. Over 50% suppression has been achieved by applying vibration control to the target vibration mode. Additionally, using this control, the machined profile has been improved, and the roundness and harmonic analysis of the workpiece showed over 30% improvement.
