Purchasing a GWeike or Shenhui Laser
Dear members of the forum,
I've been following the forum now for some time and it has really helped me out greatly with getting to understand the ups and downs of purchasing and working with a Chinese laser engraver/cutter. Thanks for everyone sharing their info here!
This week I want to purchase a G Weike or Shenhui laser with the following specs:
Laser power: 80W or 100W RECI tube
Power supply: AC220 - 50HZ
Working area: 1200x900mm
I want to include the following features/spares:
- Cooling Chiller CW5000
- auto up and down platform
- red dot
- auto focus
- honeycomb table
- aluminium knife table
- spare mirrors
- spare laser tube 80W/100W RECI brand
- spare power supply
- stepper motor for XY
- stepper motor for Z
- stepper driver
My purpose for the machine is to do laser cutting of multiplex/plywood/MDF up to 12mm and precise engraving of text.
My questions are:
1. From what I get from the forum, G Weike and Shenhui are both good value for money. Any reason to go for one or the other?
2. How much power does the laser need to cut up to 12mm multiplex/plywood/MDF?
3. In my understanding precise engraving requires you to sometimes change lenses, which size lenses should I include in my purchase?
4. Are all of the spares/features necessary, or should I remove/add some?
I hope you guys can help me with the above questions!
Thanks in advance!
