How can a woodworking engraving machine not be damaged by the knife?

The first is the parameter setting problem. When the carpenter engraving machine is positioned in the Z axis, it is not to let the knife touch the data surface, but to remove the data so that the knife directly touches the table. It can be encountered, not deep, in this local Z The axis is first zeroed, and then the corresponding height is raised according to the cutting depth set in Venter. Here, the Z axis is zeroed again. This is the origin of the Z axis. According to the depth of the setting of Wentai, the lowest point of the engraving machine is the place where my family returned to zero, which is just above the countertop, thus ensuring that the information is thoroughly penetrated without hurting the engraving machine.
Secondly, it is better to add a protective plate on the surface of the engraving machine. For example, the carpenter engraving machine with vacuum adsorption table can put a thin Ozon plate on the table. The looseness of the Ozon plate itself will not affect the vacuum adsorption, and it is also useful to avoid The tool damage and table problems caused by the ban on the origin setting.
Even if the above-mentioned treatment of the carpenter's engraving machine is used in the long-term application, it will inevitably show scratches and scratches. This time, it is necessary to start the milling platform from the head. When the electric board or PVC on the table is too thin, it can You can build a layer from the top. Another requirement is that when the machine leaves the factory, in order to prevent the damage of the countertop in the logistics transportation, it is generally required that the after-sales personnel can adjust the time of the door-to-door device.

Choose three process / pneumatic three-head tool changer engraving machine will you?

Now with the development of the decoration profession, the promotion of the real estate profession, the interior door, the sliding door, the sliding door, the demand for the cabinet door are greatly increased, and the demand for the CNC engraving equipment for the carved wooden door is also greater, so how to choose the wooden door carving machine, It is the three-step carving machine, the pneumatic three-headed knife-cutting machine or the active tool-cutting machine, you can first understand the composition of the carving machine and the characteristics of the three-step carving machine:
     When selecting the rack drive wood door carving machine, after the spindle motor is determined, the three-step carving machine must use the genuine Weihong system. Then the difference is in the selection of the drive motor. The drive motor has a stepper motor and a servo motor (the servo motor has a servo imported from Japan, a domestic servo, and a Raytheon communication servo motor).
1) Stepper motor is commonly used in Changzhou Chuangwei brand, the type has 86 series commonly used, 450B, 450C; 110 stepping motor 86 is the stepper motor diameter 86mm; 110 is the stepper motor diameter 110mm, attributed to the large type . The matching driver can be the Raytheon 860, or the 2811 large driver.
The use of bad, the noise is a little bigger, may occasionally lose the pace within a year, but the price is cheap, so the use rate is very large, if the carved material is more expensive, it is best to use the servo motor. Single-head 1325 is commonly used as a stepper motor.
2) Leisai communication servo motor (closed loop motor): affordable, more expensive than stepper motor. It is attributed to a simple hybrid servo motor.
3) Domestic servo or Japanese servo motor: all pure servo motor, low noise, high power, no lost step, the price is slightly higher 1
More than a million.
In general, four sets of servo motors are used in the XYZ axis of the single-head carving machine.
