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...

SCREW THREAD MACHINING METHOD

In  Metal parts machining  works, screw thread (tapping) be required. The screw thread is mainly divided into: connecting thread and driving thread For  connecting thread , the main  machining  methods are: tapping, threading, turning, rolling, etc. For  transmission thread , the main  machining methods  are: rough and fine turning – grinding；whirlwind  milling  – rough and fine  turning , etc. CNC turned screw thread part The following describes the various screw machining methods: THREAD CUTTING Generally, it refers to the method of machining thread on workpiece with forming tool or grinding tool, mainly including  turning , milling, tapping, threading, grinding and whirlwind cutting, etc. THREAD MILLING On the thread milling machine, the disc milling cutter or comb milling cutter is used for milling. Disc  milling  cutter is mainly used for milling trapezoid external thread of screw rod, worm and o...
