green green laser pointer are more expensive than red ones

Generally, green  green laser pointer  are more expensive than red ones.   To make the site is always in a tight and secure with the state, the event of a crash of the key loose coupling, the coupling cushion should be replaced immediately and key. The band gap for a long time to change back will make the shaft keyway deformation Da. 4, the control of the online cable between the cabinet and the machine, mopping the floor some have a lid or plastic sheeting to protect, is not free to stampede the cable in a relaxed free state, not external pull cable plug, not force, not to cable corrugated sheath fracturing crushed.
There is only a small number of manufacturers who produce green  green laser pointer . Console (cabinet) when it is moved to light-light, greasy hands Do not plug or unplug the touch connectors or keyboard. Any part of the bed surface are not allowed to knock smashing or collision, especially not to make a wire rack and bed interference, it would be serious damage to machine parts or precision due to overtravel movement. 7, we should always pay attention to the conductive block in the insulation between the good electrical conductivity and bed, workbench pads must bed insulation, stepper motor delay line in a free state.
 the stepper motor to ensure that no dirty water intrusion. WEDM common knowledge Q & A (first-line cutting common quiz) you know the wire cut? Wire cutting machining born late 1960s, the initial development in the 1970s, popularity of the 1980s, has now been to end the era of on the steps.   Hence, the cost of green  green laser pointer  is higher than red ones. Many people, especially mold expect the industry has long been a means, as the wire saw cutting wood cutting steel is quenched hardness. To solve the problem of complex shapes, but also to resolve the sharp corners and clear inside and outside the root problem.
Fifties, EDM beginning to be recognized, EDM into the processing area, though it was only solve the hardness, playing some sort of tap drill. But this is the beginning of the popular EDM in the mold industry. When people have come to realize if the wire saws plus the "spark", "Saw" has a hardness of hardened steel, it should be possible. Thus, a large number of the axis Chu copper wound round by the two guide wire shaft to another storage, placed between two guide rollers workpiece, the workpiece. The red laser module technology adopted in red  green laser pointer   is relatively mature. 
 then the RC power of positive copper wire connected to the negative terminal of the RC power supply, it spark cutting. Although the two storage wire axis films disk replacement, tension wire was made by all kinds of friction was the rust-proof deodorant grinder coolant working fluids, after all, a "wire electrode spark cutting . " The early sixties, some military enterprises and mold industry is the backbone plant began manufacturing the form of technological innovation, home-made personal use of the "wire cutting". Mostly with copper wire, wire-speed of 5 m / min,   The materials for making green  green laser pointer  are better.
