Common sense about CNC engraving machine, do you know how much

Driving system introduction

At present, the engraving machine drive system is mainly divided into two categories of stepping system and self-service system, the stepping system dominates this reason to affordable to meet the general customer requirements, the stepping system belongs to the semi-closed-loop system accuracy to step angle calculation, the self-service system belongs to the closed-loop mode within the measurement feedback system, so the accuracy of the relatively high, high power, smooth operation, high demand for the customer can choose the self-service drive system The machine (price is a little expensive). Currently on the market also appeared in the half-private service system, is an improved version of the stepping system, please pay attention to customer selection of machines. (divided into domestic and imported)

Control system:

Currently to the Weihong, DSP operating system, mach3 for the leading less, imported Taiwan Bao Yuan and new generation control system.

Mapping software:

General use, Wentai, fine engraving, TYPE3, artcam.

Engraving machine transmission mode:

At present, the engraving machine is divided into three transmission methods, screw drive, rack and pinion drive and synchronous belt drive.

Screw machine advantages and disadvantages:

Screw drive is the origin of the engraving machine transmission mode, characterized by high precision, slow running speed, high environmental requirements, relatively short service life, Y-axis single screw is not easy to be too long (models can not be too large), high-speed operation is easy to jitter, if the installation of low precision Y-axis screw will be thrown off for a long time running the possibility of breakage. If the requirement of high precision can be Y axis double screw structure to meet the requirements, general processing speed of about 7 meters. (Mainly applicable to advertising, wood products, small crafts, lighter stone according to different tools can be processed any carving material)

Rack and pinion machine advantages and disadvantages:

Rack and pinion machine is both the upgraded version of the screw machine, between the screw machine can not meet the requirements of high-speed processing and the newly developed models, fast speed, environmental requirements are not harsh relative to the long service life, precision relative to the screw machine is a little lower, rack and pinion machine Y-axis X-axis for the rack and pinion drive, Z-axis is generally driven by the screw, the accuracy requirements are mainly based on the guideway and rack and pinion mesh precision to decide. Machine size and length can be large enough, easy maintenance is generally equipped with manual oiling system, the proposed processing speed up to about 15 meters. (Mainly suitable for woodworking products processing, paint-free doors, cabinet doors, solid wood doors, screens and other panels cutting, hollowing relief can also be processed advertising also stone, marble and other materials specifically according to the tool selection).

Synchronous belt drive:

Synchronous belt drive is mainly used for laser engraving machine and plasma cutting, light weight, high precision, good maintenance, time is easy to relax affect the processing accuracy and other characteristics. (Laser machine is mainly used in advertising, crafts engraving, cloth, leather, glass, stone, crystal and other non-metallic materials such as shadow carving line carving can also be processed in a few metal materials, the price range and the power of the laser tube).
