Shark 420CNC HS是一款全自动数字控制的双立柱带锯床，适合0°切割，特别针对超硬的合金材料，不锈钢和实心体的材料，大切割范围为420×420 mm
这款设备也可以半自动工作，电路系统采用型的RISC 32 bit 200 MHz 控制系统。可以在设备上安装GSM卡（选装件），当设备不能够正常工作时，能够自动发送短信到编程好的号码上提醒紧急状态的原因。并且可以实现远程操控。
主要特点:
- 锯弓的上下限位可以根据锯切材料的大小通过控制键盘调整
- 机器可以储存300组不同长度和数量的程序。
- 机身整体铸件可以吸收震动保证锯切的平稳和更长的*寿命。
- 锯弓沿着线性导轨和丝杠上下，受伺服马达控制，并且液压补偿锯弓头
- 液压工作站给送料和卡钳夹紧提供动力
- 锯条的转速受变频器控制，连续可调

- 全自动模式下，短余料长度为120mm,可以选装特殊卡钳减少余料长度到25mm
- 送料卡钳可以在材料不是很直的情况下，自动寻找中心线
- 软件可以自动控制/评价/纠正：锯切力，锯切扭力，锯条涨紧力
- 可调整的硬质合金导向头，以及冷却液装置（可选油冷）
- 更换锯条时，可以方便的从键盘上调整锯条的涨紧力
- 前导向臂可以根据不同切割直径的材料自动调整位置
- 激光指示灯可以投影在材料表面，可以容易的找到需要切割的位置
- 锯条受力超过接受能力时，机器可能停机以保护锯条
- 电子伺服系统可以保证锯条上的涨紧力始终保持一致
- 声音和闪光会提醒锯床停止工作，
- 服务钥匙和指导手册以及零部件清单
MEP SPA introduces the NEW Shark 420 CNC HS, automatic double-column bandsaw for 0° cuts on structural, stainless and alloy steels,profiles and solid parts, with dimensions up to 420×420 mm.
This sawing machine also features a semiautomatic cutting cycle and uses latest generation technologies; indeed, Shark 420 CNC HS is equipped with a NEW controller with processor RISC 32 bit 200 MHz with integrated interface to:
- install a GSM card (OPTIONAL) to send an SMS to the programmed number notifying the type of emergency occurred while the machine was operating unattended.
- Connect to an Ethernet network for the remote assistance service.
- Get software updates and changes by , to be transferred on SD or MMC card and later on the control memory, through the suitable slot on the control console.
- Choose in the library (that can be extended by the user) the material type, geometry and hardness, the type of bａnd to be used and the control automatically sets the feed rate and the bａnd rotation speed.
OTHER FEATURES:
- The limits of the head stroke are programmed through the console, depending on the dimensions of the bars to be cut.
- CNC machine to store up to 300 cutting programs each with different quantity and length.
- Structure in sturdy cast iron, to absorb vibrations and give the machine a better cutting stability and longer blade life.
- Saw frame movement with a brushless motor and with recirculating ballscrews-nut, with hydraulic compensation of the cutting head.
- The head movement by means the linear guides with ball-recirculating pre-charged slides.
- Hydraulic power pack to supply the feeding and cutting vices.
- Infinitely adjustable cutting speed from 15 to 115 m/min by vector inverter.
- Bar feeder with recirculating balls screw/nut and stepper motor,(feeding length in one stroke 600 mm, that can be repeated in order to cut any length)
- Minimum bar remnant of 120 mm in automatic operation. (OPTIONAL feeder jaws to reduce the remnant to min. 25mm)
- Self-aligning feeder vice unit for feeding even strained bars.
- Driving and idler pulley locked by conical clamping ring to ensure a strong fastening .
- Software to control/assess/correct in real time: – cutting force – cutting torque and bａnd tensioning against the programmed values.
- Low voltage control panel installed on a rotating arm to reach the positions to operate safely stillkeeping the visual control.
- Soft thermo-shaped keyboard in polyester, with SMD miniaturized mechanical buttons integrated in the card, with sound signal when operating, 5.7″ colour display with self-diagnostics messages.
- Adjustable blade-guide heads in steel, with roller and carbide pads, coolant taps for the traditional lubrication and preset to install the mist lubrication (OPTIONAL).
- Idler pulley movement from the keyboard to replace the bａnd easily.
- Automatic adjustment of the front blade-guide head according to the dimensions of the bars to be cut.
- Laser projector to position the bar accurately to carry out non-standard or facing cuts.
- Bａnd rotation control with stop in real time in case of locked tool.
- Electro-mechanical servo-system for the blade dynamic tensioning.
- Coolant tank incorporated in the base.
- Two coolant pumps to ensure high cutting liquid quantities (120 l/min) to cool down the bａnd and wash up chips from the working area, so as to guarantee a longer blade life.
- Wash gun to clean the working area.
- Blade brush.
- Sound and flashing indicator for machine shut-downs.
- Machine preset for being handled also with lift truck.
- Bimetallic bａnd for profiles and solid pieces.
- Service keys and instructions manual, for maintenance and spare parts list.
