USE HIGH TEMPERATURE TO CLEAN BURRS

High temperature to clean burrs.

Principle of high temperature burr free:

First place the parts to be deburred in the tight sealing chamber, and then send the mixture of hydrogen and oxygen with a certain pressure. After the spark plug ignites, the mixture will explode instantaneously, releasing a large amount of heat, and the instantaneous temperature is as high as 3300 ℃.
Due to the short explosion time, the burr of the part is burned out, while the other parts of the part are too late to change. In case of explosion, the high-pressure gas is all pervasive, and all the burr of inner hole, cross hole, groove, deep hole, etc. of parts can be burned off. Special high temperature deburring machine is needed.

Application scope of high temperature burr free:

This method is suitable for deburring of metal partplastic and rubber parts with any structural shape, especially for parts with complex shape and difficult to be deburred by hand.

Principle and method of high temperature burr free:

In the process of operation, according to the materials of different parts, choose the appropriate mix ratio of hydrogen and oxygen (refers to the molar mass ratio of hydrogen and oxygen in the sealing chamber). Steel, alloy steel and copper are not sensitive to the mix gas. The mix ratio of hydrogen and oxygen can be in the range of 2:1 ~ 2:2, and the mix ratio of aluminum alloy is slightly higher than 2:1.
Secondly, the inflation pressure (referring to the mixture pressure in the sealing chamber) should be selected. Generally speaking, the inflation pressure of steel and alloy steel is high, followed by brass and aluminum alloy.
Before deburring, the parts must be cleaned and dried; after deburring, they shall be neutralized in phosphoric acid mixed solution to remove the oxide film.

CNC MACHINE BE CLASSIFIED BY SERVO CONTROL MODE

Servo control mode to classify CNC machine tool. (1) open loop control CNC machine tool The feed servo drive of this kind of machine tool is open-loop, that is, there is no detection feedback device. Generally, its driving motor is a stepping motor. The main feature of stepping motor is that every time the control circuit changes the command pulse signal, the motor will rotate a step angle, and the motor itself has self-locking ability. The drive circuit is controlled by the pulse distributor, which controls the coordinate displacement by changing the number of pulses, the displacement speed by changing the frequency of pulses, and the direction of displacement by changing the distribution sequence of pulses. Therefore, this control mode is characterized by convenient control, simple structure and low price. The command signal flow from the CNC system is unidirectional, so there is no stability problem of the control system, but because the error of the mechanical transmission...

Tapping failure reasons analysis

After the first metal part be tapped, we always to check it: if pass the thread gauge inspection? The inspection result is OK, we can do mass production. If it fails, We should consider which reasons cause tapping faiulre. KYLT provide Metal Machining services for:  WEDM, EDM, DRILL, TAPPING ,  CNC LATHING ,  CNC MILLING ,  ALUMINUM / MAGNESIUM / PLASTIC RAPID PROTOTYPES MAKING . 1PCS ORDER IS ALLOWED. Aluminum CNC machined workpiece Normally, the following reasons may cause screw thread faiulre: 1) UNQUALIFIED TAP Tap is wear or bad 2) QUALIFIED DRILLING HOLE (BEFORE TAPPING) If the hole is too small, because of friction, will increase the difficulty of tapping, while tapping faster wear, and vice versa, the hole is too big, it can easily tap into, but the quality of teeth is very poor, because the diameter of teeth will become larger, relative to the screw nut bonding force is insufficient, easy to slide teeth. In M3 *0.5, the correct hole (general...

SELECTION PRINCIPLE OF CUTTING PARAMETERS FOR SCREW THREAD TURNING

Because the pitch (or lead) of the thread is specified by the drawing, the key to choose the cutting parameters when  turning  the screw thread is to determine the spindle speed n and the cutting depth AP. 1) SELECTION OF SPINDLE SPEED TO DO SCREW THREAD TURNING According to the mechanism that the spindle turns 1 and the cutter feeds 1 lead when turning the thread, the feed speed of the CNC lathe is determined by the selected spindle speed. The thread lead (which is the pitch when the thread is single head thread) instructed in the thread processing program section is equivalent to the feed speed VF VF = n f (1) expressed by the feed rate f (mm / R) From Formula 1, it can be seen that the feed speed VF is proportional to the feed amount F. if the spindle speed of the machine tool is selected too high, the converted feed speed will greatly exceed the rated feed speed of the machine tool. Therefore, when selecting the rotation speed of the main shaft for turning the threa...
