At present, economical CNC machine tools are still the most demanding CNC machine tools in China. Utilizing the existing idle old machine tools and transforming them into a new high-efficiency and versatile economical CNC machine tool through numerical control, it is an effective method for revitalizing the stock funds and one of the roads to achieve automation at low cost. The CK6130 small CNC lathe we developed is the exploration and practice of this idea.
1 Working principle CK6130 small CNC lathe consists of two parts: the microcomputer numerical control system and the machine body. When machining the workpiece, firstly program the NC program of the workpiece, then input the CNC program that can be checked into the numerical control device, and then calculate the feed pulse sequence according to the program command by the numerical control device, and then the multi-function NC board performs pulse distribution, and the power amplifier or After the power is amplified by the driving power source, a control signal of the driving device is formed, thereby controlling the rotation speed of the machine tool spindle, starting and stopping, the moving direction, the speed and the displacement of the feeding system, and the selection of the tool, the start and stop of the cooling and lubrication, etc. The tool and workpiece and other auxiliary devices work strictly in accordance with the sequence, stroke and parameters specified by the NC program, thus processing the shape, size and precision to achieve a friendly human-machine interface.
3 Conclusion The CNC system is based on the general industrial control machine. It adopts the powerful motion controller PMAC to undertake real-time tasks such as interpolation calculation, position control and speed control, achieving two levels of openness, making the CNC system have special The system has better human-computer interaction capability and upper-level application system integration capability, which is convenient for manufacturers and users to customize and adjust the system functions, so that the system has better adaptability. The numerical control system has been applied to the development of the SKB2320A wall panel milling machine and has achieved good results.

• Excellent mold-making ability.
Our R&D team, with over 30 years` experiences, work with high quality mold-making equipment imported from Germany and professional mold analysis software that allow NEST to develop more precise molds.
• Injection molding in Class 10,000 and Class 100,000 clean rooms, with strict quality control.
10,764 ft2 Class 10,000 clean room and 32292 ft2 Class 100,000 clean room, all-electric high-speed injection molding machines imported from Japan, raw material which meet USP Class VI requirements. Production and quality control are performed strictly in accordance with corresponding SOP.
• Sterilization by electronic beam irradiation.
The Rhodotron TT200 electron accelerator which imported from the IBA company, Belgium. A world leader in the E-Beam sterilization industry. Sterilization process has been certified by the ISO 11137 quality system. Compared with sterilization by cobalt 60 or ethylene oxide sterilization, sterilization by electronic beam irradiation is more efficient and safer. It requires less time and will not produce any chemical residue.
Vacuum Filtration Systems
NEST Disposable Vacuum Filtration System is useful for large volume sample separation and sterilization for tissue culture media and other biological buffers. The units include PES or PVDF membrane filters with graduated filter tops made with polystyrene, and Acrylonitrile-Butadiene-Styrene necks with polystyrene receiving bottles. A separated sterile polyethylene cap is included. Filtration system is manufactured from raw material of high transparency polystyrene (PS) in three different volumes: 250mL / 500mL / 1000mL. They are available in three styles: complete filter/ Storage Bottle systems, bottle top filters, and receiving bottles only.
