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.

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.

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

Moving Tanker for Coolant 

Water cooling Spindle : Quality 5.5kw water-cooling spindle performs powerfully and stably. We offers different spindle options which available with 220V-2 Phase-50-60Hz or 220V-3 Phase-50-60Hz or 380V,3Phase-50-60Hz.Series of tools are available,for example, diameter 3.175mm,4mm,6mm,8mm and 12.7mm.

Linear Guide: 30MM Linear Guide from THK,it is an ultra-heavy type that achieves a deep grooved raceway with its diameter more approximate to the ball diameter and has high rigidity, vibration and shock resistance, and damping characteristics.Beside,it is mounted on the upper surface of the steel pipe for greater loading bearing and more steady motion. 

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.

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

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.

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

Photoelectric Limit Switch: Un-touching ,more sensitive and durable than traditional mechanical switch,maintenance-free for long term use.

Spray Head:Multiple spray head to cool the Tool from different sides.
