I've been in contac with Shanny form JCUT and its been very imformative. the following is the spec for the machine:
Large Wood CNC Router machine JCUT-1530B (59''x118'')
Features: Optional(vacuum table and dust collector)
1) Machine body: Whole cast iron
Ask for photos of the underside during manufacture as mine was covered in slag and sand from the casting, it still vibrates off a little now and then on mine! This appears to be very common with most vendors.
2) Guideway: XYZ-axis use linear guideway
Good!
3) Driving mode: Rack
Sure it's rack? Mine was indicated to be rack but turned out linear, which i'm happy with actually. I thought rack was more suited to a closed loop system like servos? Recommend you find out the specs of the rack to check quality.
4) Work dimensions: 1, 500mm x 3000mm x 150mm
5) Body dimensions: 1, 900mm x 3700mm x 1, 650mm (with bracket)
6) Z-axis working area: 80mm(or 150mm)
I would consider 80mm a complete waste on a machine this size, unless you are only ever going to machine sheets of MDF or similar. 80mm travel really limits the possibilities badly.
7) Max. Feeding height: 120mm or bigger
Apparently these specs can change at any time, I'd pin them down on what YOU'LL get!
8) Cut thickness of material: ≤ 40mm
Foam maybe, but this is a meaningless figure anyway, the construction of the frame, the steppers and controller used, and the spindle is what determines this according to the material.
9) Max. Speed: 25, 000mm/min
10) Working speed: 0 - 8, 000mm/min
Wow!
11) Mechanical precision: 0.01mm
There's a fairly good chance being a beefy and very heavy machine the manufacturing tolerance will do this resolution. If I tweak and work on mine I would get that kind of res easy, your's will be much more robust than mine i'm guessing.
12) Software: Type 3 software, Artcut software, Artcam software
Ahem...cough...warez...cough!
13) Max. Power consumption: 3kW
As powerful as you could possibly want it, 0.8kw machines aluminium fine as a comparison.
14) Power source: AC 220/50/60Hz (or 110V/60Hz)
15) Driver type: Stepper motor(XZ-85BYG, Y-axis use two 85BYG motors)
85BYG denotes a range of steppers, I'd strongly suggest they provide the EXACT spec of the stepper on each axis, as well as the drivers used, and the power supply specs. There was massive confusion with my machine as to what the motors were, and I only was sure when the machine arrived and I checked what they were. Two I feel are somewhat underpowered for the machine.
16) Memory: Without or (DSP)
17) Spindle: 2.2kW( 100mm) variable speed, water cooled motor (3kW, or bigger)
I far prefer water cooled, but others here have argued against them.
18) Spindle speed: 0 - 24, 000rpm/min
19) Blade diameter: 3.175mm, 4mm, 6mm (or 8mm, 10mm, 12mm, 12.7mm)
20) Control system: (NCSTUDIO) or DSP (USB interface) (chosen NCSTUDIO)
Once you get used to it NCstudio is not completely horrible, it is the official software for all these machines and is very stable and functional I have found. Still not as good or feature rich as Mach3 though IMHO.
21) Command: G code, u00, mmg, plt
22) Running circumstance temperature: 0 - 45° C
23) Relative humidity: 30% - 75%
Packing:
Pack dimensions: 1, 750 x 3500 x 1, 750mm
Net weight: 1100kg (with bracket)
Gross weight: 1300kg
I'm from the UK and was hoping if you can help me decide whether this machine would be money well spent. Could I ask shanny to make any amendments to this specification before purchase?
How much?
Thanks
