The steel is heated to a temperature above the critical range, after which it is cooled in still air to produce a generally fine pearlite structure. The purpose is to promote uniformity of structure and properties after a hot-working operation such as forging or extrusion. Steels may be placed in service in the normalized condition, or they may be subjected to additional thermal treatment after subsequent machining or other operations.

A servo motor is an engine that controls the operation of the mechanical components in the servo system. Servo motor can make the control speed, position accuracy is very accurate, can be converted to torque and speed voltage signals to drive the control object. Servo motor rotor speed by the control signal input, and can respond quickly, in the automatic control system that is used for the implementation of components, and has small electromechanical time constant, high linearity, initiating voltage low characteristic, the received signal is converted into the motor shaft angular velocity or displacement output. DC and AC servo motor is divided into two major categories, the main feature is that when the signal voltage is zero without rotation, speed with the increase of torque and uniform decline.  Click to download

A large number of reduction in the number of tooling, the processing of complex shape parts do not require complex tooling. If you want to change the shape and size of parts, only need to modify the parts processing procedures, suitable for new product development and modification.

The machining quality is stable, the processing precision is high, the repetition precision is high, and the processing request of the aircraft is adapted.

The production efficiency of multi varieties and small batch production is higher, which can reduce the time of production preparation, machine tool adjustment and working procedure inspection, and the cutting time is reduced by using the optimum cutting quantity.

The conventional method of processing complex can be difficult to process the surface, even some can not observe the processing parts processing.

The disadvantage of CNC machining is that the equipment is expensive and requires the maintenance personnel to have a high level.

CNC turret is to realize the automatic exchange of cutting tool and the transmission of 
rotary power tool. As a result of high technical content, has been the trend of professional developmentProduced. So the research and development of CNC turret and the application of CNC machine tool industry has attracted attention. Typical numerical control turret turret is generally powered by Source (motor or cylinder, hydraulic motor), mechanical transmission mechanism, pre graduation mechanism, positioning mechanism, locking mechanism, detection device, interface circuit,Tool mounting table (Dao Pan), power tool holder and so on. The action cycle of the turret of the numerical control turret is as follows: the T command (for the change of the cutter instructions -- the cutter head rotation -- the tool bit check Pre - Test - cutter - precise positioning locking - end signal.  Click to download

NC programming is one of the main contents in the preparation of NC machining process, which usually includes the analysis of part drawings and the process of machining process;The calculation of the tool path, the tool bit data, the preparation of NC machining program; production control media; proof reading program and the first test.There are two methods of manual programming and automatic programming. In a word, it is the whole process from the part drawing to the numerical control machining program.
