1. BRIEF INTRODUCTION of EZCNC ROUTER GR SERIES
With innovation design of dual ball screw with driven nut, EZ CNC Router GR Series have high speed, high precision and high stability. The perfect combination of innovative technology, professional design and high quality accessories achieves the classic, perfect and professional CNC routers.
(1) Innovative Dual Ball Screw With Driven Nut Technology
EZ GR series adopt innovative dual ball screw with driven nut technology. Ball screw is a product what converts the rotary motive into a linear motion or a linear motion into a rotary motion. The ball screw was widely used in industrial machines and precision instruments. Because the ball screw would support some advantages, such as slowing wear resistance, improving high transmission efficiency, making transmission smoothly, improving precision, making temperature rising slowly. GR series can make accuracy error less than 0.01, speed up to 30m/min.
(2) Driving System
EZLETTER GR series adopted Japan imported YASKAWA digital servo. Comparing with step motor drivers, it is more precise than step motor drivers. So that each turn of the servo motor to the servo drive and CNC control system output 16384 pulses for feedback control. The use of servo systems can be overloaded, which means higher speed, faster acceleration and greater cutting force.
GR series gantry machining center adopted dual ball screw technology, it would largely enhance shock resistance, reduce the vibration about ten times. Adjusting dynamic characteristic, the acceleration of 3 axes will be increased to 1G. According to adopt innovation dual ball screw, the gantry and the spindle will be keeping balance when the machine is working. It is a great way to enhance stability, precision, speed.
HSD 3HP Spindle
Power: 380V/9kW
Spindle Speed: 24000rpm
Air cooled
Advantage:
1. Adopting high speed chunk and nut with working stability, high speed.
2. Passing strict dynamic balance, and satisfy requirements of high speed
3. It contained the function of automatic tools changer
(3) Fagor Controller
Fagor Automation offers an integral solution to high performance machining centers and production lathes because of our large selection of features. Our CNC systems meet the most demanding requirements. The range of CNC's goes from conversational programming CNCs for short production series that require quickness to high-speed CNCs with nanometric accuracy for machines of high technological value or CNC systems for specific applications such as Laser cutting, etc.
Fagor CNCs are designed for all kinds of machines with additional benefits:
-Easy programming. There is no need to know ISO programming language.
- Algorithm that provides the best performance, speed and accuracy in
the machining process.
- Ergonomic and functional design (touch-screen, easy navigation,
integrated manuals, sms communication, high-resolution graphics,
keyboards and monitors with the highest level of sealing protection,
etc.)
- Interface customizing tools.
- Free software download with no time limit to work at any PC.
- Axis position control (position loop) every 250 s.
- Technological features like Look-Ahead. The CNC analyzes in advance the changes in the
movements of the axes providing high speed machining. Our CNCs analyze 2,400 blocks in
advance and block processing time is 0.25 ms.
(4) Carrousel Tools Changer
GR Series adopt carrousel tools changer, comparing to linear tools changer, this technology will be better because it could contain 8 knives. The route is shorter that the linear tools changer. The ATC would save much time in tools changing. Then, we add dust cap on the equipment, dust will be isolated to knife and the durability of knife will be expanded. Considering some situation of tools collision, this equipment was installed a reliable air collision avoidance system.
(5) Vacuum Table
Vacuum system can materials on the table surface, comparing to the traditional manual clamping, it will improve production efficiency. The material is adsorbed on operation table, the middle of the material will not appear shifting. At the meanwhile, each partition is a separate part, the seal was made from special materials with waterproof and oil resistance.
(6) Automatic Tool Sensor
Auto calibrate tool sensor, it can write all tool parameters into the system through automatically calibrate and save much time comparing with traditional manual calibration. For presetting the tool length with an accuracy of 0,01mm.
(7) Software
GR Series can work through some software which will output G code, for example: Wentai engraving software, Jingdiao engraving software, Type3, ArtCAM, AlphaCAM, AutoCAD, Cimatron, MasterCAM, Enrouter. According to the customer requirement, we also can support V-Carve Pro software service.
(8) Compressed Air Specification
To ensure proper operation of devices installed on the machine that use compressed air, and in particular the spindle, the compressed air supplied must comply with the following characteristics
Inject compressed air with a purity rating complying with ISO 8573-1, types 2, 4, 3,
i.e:
- Type 2 for solid particles: size of solid particles < 1 m.
- Type 4 for humidity: dew point < 3°C (37.4°F).
- Type 3 for total oil: oil concentration < 1 mg/m3
