Relevant accessories

Base Frame: The base frame is made of heavy-duty tubular steel that is welded, precisely machined by gantry milling machine and stress relieved by vibration device,the gantry supports are enhanced so that the foundation remains true and steady over the operational life of the machine.

Guide and Gear Rack: we use precision gear racks,carefully installed and regulated by experienced worker with special purpose instrument ,this assures smooth motion and long term reliability. Quality 25MM linear square guide from with high rigidity, vibration and shock resistance, and damping characteristics.

NC Studio Controller: PC based NC Studio Controller with more friendly human&machine interface/HMI,fully executed with computer. It well realizes high-speed and high-precision motion control.Better anti-interference performance due to control signal adopting differential signal input&output,featured as power failure protection function,linear interpolation, circular interpolation, intelligent look-ahead, reverse cutting, backlash compensation, breakpoint memory and block skip, etc.

Electric Cabinet:All the electrical components are housed and wired in a mobile,doubled-doored electrical enclosure. This allows for easy access and service when needed. Every wire is tagged so that when service is required, the customer can easily navigate the cabinet.

Water Cooling Spindle : 5.5kw Quality spindle performs powerfully and stably. Series of tools are available,for example, diameter 3.175mm,4mm,6mm,8mm and 12.7mm. With Spray Head to cool the Tool from different sides.

Ball Screw:Quality TBI Anti-Backlash center driven ball screws with 25mm diameter and 0.01mm repositioning accuracy. The combination of ball screw and gear rack offers accuracy and high speed machining.

Balance Cylinder:they stop dropping of Z axis in case of electricity cutting,which can protect spindle,tool and material.

Contact Roller:They are high strength and wearable rollers which help you to load heavy stone easily.

Central Lubricator: Easier to lubricate the Guid units regularly,just pull it gently and oil will go when it is needed.

Servo Motor: AC Panasonic Servo motor for more smooth motion and triple working speed,and they require no regular maintenance.

3D Scanner: A fast and easy to operate device for massive production based on complicated three-dimensional samples.Good for woodworking,small molds,  
plastic products, shoe last and soles mold, sculpture, artifacts, toy, tooth, jewelry design, core carving, fine pieces design, small toy parts, etc.
