How to use thread gauge

Screw thread gauge usage : to be used to check thread after machining to meet machined parts manufacturing tolerances.

The usage of thread gauge (sub-screw, and screw coil)

A. UNDERSTANDING THREAD GAUGE STRUCTURE

1) The T (through) end is usually longer than the Z (stop) end.
2) There is a ditch in the middle of the British system.
3) Generally hardened (quenched) steel grinding, very brittle fall on the ground will break;
4) After long-term use, it will wear and tear. Generally, it needs to be re-examined more than 1000 times.

B. USAGE OF SCREW THREAD GAUGE

Only those who pass the quality assurance inspection or qualified labels (attached to boxes) can be used.
Long-term use must be used about 10,000 times (can be estimated) after inspection qualified reuse.
When use screw thread gauge check the machined parts thread hole. With the gloved thumb, index finger clamping light rotation, avoid vigorous, then T (through) end is qualified, Z (stop) end into 1 ~ 2 teeth, no longer qualified, must not use vigorous, after using the thread gauge, must be clean with clean soft cloth thread gauge (sample ring or column) to be wiped, coated with rust-proof oil back to the box.

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...

MEASURES TO IMPROVE THE MACHINED PARTS SURFACE QUALITY

Measures to improve the surface quality of  machined parts Improve operator skills The operator must master the technology of tool fixing and tool setting. Tool fixing and tool setting is an important and very difficult basic work in  CNC machining . The good and bad of tool loading and tool setting will directly affect the programming of machining program and the dimensional accuracy of  machining parts.  Only mastering the technology of tool setting and tool setting can guarantee the machining quality. The tool setting is generally divided into manual tool setting and automatic tool setting. At present, the vast majority of CNC machine tools use manual tool setting, and the commonly used tool setting method is trial cutting. It can get more accurate and reliable results. KYLT Stainless steel cnc turning service The simulation system of CNC lathe is used to check the program: after the program is input in the machine panel, the program must be simulated fir...
