First thing to consider after-sales service:
Laser tube, lenses are consumable parts, their lives are certain, they need to be replaced after the expiration. This requires manufacturers to provide strong after-sales service, can timely provide these supplies. Some users for the sake of cheap, small plants from a very low price to buy laser engraving machine, half a year later, laser engraving machine need to replace the laser tube, and manufacturers a link and found empty.
Second, we must consider the quality of products
as the saying goes, watch amateur, professional and subtle. Is also a laser engraving machine, not the same parts used in the following example:
a) stepper motor: related to the precision of laser engraving machine, and some manufacturers choose to import the stepper motor, some joint-venture plant raw plant stepper motor, some no-name motor.
b) The laser lens: relationship of power to the Laser engraving machine the size of the lens sub-imports, domestic lens, the lens made of imported materials, which is divided into the production and use of domestic production of the two materials, the price gap between the great use of effects and life gap is also large.
c) Laser is the heart of the machine. As the import of expensive laser tube, usually in a few million, so most of the laser engraving machines is made used domestic laser tube. The laser tube is made good and bad, the price gap is large. Laser tube life is generally good in 3000 hours.
d) Mechanical assembly quality: some manufacturers to reduce costs, the use of thin metal shell making machine, the user generally can not see, but over time, frame deformation will occur, affecting the precision of laser engraving machine engraving. Good laser engraving machine frame structure should be used, the use of high-quality steel welded together and used to produce high-quality cold-rolled steel chassis.
Third, we must consider the machine’s features:
Some people who are familiar with laser engraver laments, laser engraving machine is now configured to increase so much. The following purchase of laser engraving machine from the uses to explain:
a) engraving rubber plates for printing the carton:
Most laser engraving machine can be used to rubber-carving board, you do not need to select those numerous, very fast machine, because the numerous features you rarely not on; engraving speed is irrelevant, because the sculpture rubber plate speed
Most laser engraving machine can be used to carving crafts, according to the requirements to select:
Carved bamboo, wood, small accessories: choose a small machine, such as 300X400 format, cheap, high precision carved wooden box, wine box: Select the 500X700, 600×900 format of the machine, and have a lifting platform, or a long wooden box to put do not go.
c) cutting acrylic sheet
Most laser engraving machine can be used to cut acrylic sheet, but I suggest or choose a dedicated laser cutting machine, laser cutting machine because it is optimized for the design of laser cutting, cutting effect is very good. If you still insist on enough to buy common laser engraving machine, it must have to choose a “bed knife” device laser engraving machine. Remember: Do not believe some manufacturers say 60w, 80w machine can cut 20mm thick acrylic, which is impossible, even if we manage to cut through, and that cutting edge is appalling. Normal values:
60w laser engraving machine can cut 8-10mm Acrylic, 80w laser engraving machine can cut 8-15mm acrylic.
d) clothing, leather carving cutting
Select the cutting speed and cutting platform with cellular laser engraving machine.
Choose our laser engraving machine is the right to determine.
