Abstract: The transformation of ordinary machine tools are CNC machining of small and medium enterprises to improve the accuracy of a way to reduce the auxiliary processing time is now shorter processing time is a major means of automatic rotary tool holder so the transformation

is the main part of NC.

Keywords: CNC turret rotation transformation of the Hall element

1 Introduction

Machine is the basis of equipment manufacturing industry, which directly affects the level of technology manufacturing industry. Currently, the processing center as the representative of the NC machine tool commonly used by developed countries has become a modern industrial manufacturing plant processing unit. From the development of general machine tools to CNC machine tools, machine tool structure in the transmission and a leap forward with this adaptation, CNC machine tools in its structural design will surely require new design methods and theories to guide.

China as a developing country, the CNC machine tools are expensive, some SMEs unable

to acquire CNC machine, so the general transformation of NC machine tools is a better and more economical way, a CK6140 needs funds 115,000, while the CA6140 CNC Lathe 2.7 million renovation needs.

Machine tool holder is one of the main components, but also one of the objects need to transform NC. Turret accuracy, rigidity and reliability of a direct impact on machine performance, in the deadly machine analysis, the deadly turret is the highest degree, digital control system to issue commands, the turret does not turn position, knife switch bit errors, misplaced turret, turret alarm, turret tool change and a series

of failures can not be normal so that the machine will not work properly. This paper briefly describes the economic CA6140 Machine Tool CNC turret part of the transformation of the transformation of design.

The need for reform knife, according to the modified object to determine the main processing machine. If using a knife to complete the processing on this machine, there is no need to transform the knife. For multi-knife, such as lathe modified take three or four knives to complete all the sewing process, we must transform the turret components. That removed the original manual turret, fitted with electric or hydraulic drive controlled by the numerical control device of automatic knife.

Turret lathe is mainly used for holding the cutting tool used, so a direct impact on the structure function of the cutting lathe and cutting efficiency, according to the type of machine tool holder, properties and use the occasion of the comprehensive comparison, the specific use by the Changzhou Wang of CNC equipment factory production L D4-CK6140 four-station automatic rotary tool holder. The turret has shifted fast, high positioning accuracy, the advantages of tangential torque, sending translocation by the Hall element, long life. Rotating turret with automatic replacement of ordinary knife, remove the original turret and small slide plate, put LD4-CK6140 electric knife.

2, the turret control design

2.1 The process of tool change

Rotating turret tool change, the first cutter release (lift), cutter knife near translocation arrived at the designated position, the last cutter reset (drop) clamping. When the control
