Laser engraving on plastics and reflective metals

Miyachi Unitek's LMV1000G diode-pumped high speed precision laseris specifically designed for laser engraving or laser marking applications on plastics and reflective metals.

The LMV1000G yttrium vanadate (Nd:YVO4) laser marker features second harmonic generation (SHG) output using non-linear optical elements that emit a green laser beam in the visible spectrum. The green beam's focus spot diameter is 50 percent smaller, and the energy density is four times stronger than the 1064nm wavelength, enabling highly precise marking on a wider range of materials, including copper and gold, carbon and stainless steels, bare and anodized aluminum, titanium, and as acrylonitrile butadiene styrene (ABS), as well as lexan, other plastics, and resins.

Paperless Recorder KH200B-F Mini Blue

KH200B-F mini blue paperless recorder (72x72x105mm, up to 4 channels) is blue LCD display; universal input such as thermocouple, thermal resistance, current and voltage; adopts SMT technology, modular structure output functions such as alarm (max 2 outputs), auxiliary power supply for sensors output, retransmission, print and communication etc. Measuring data can be displayed in various types, such as graphic display as bar-graph, real-time trending, history trending memory, alarming state display; also can be printed in curve and data by mini printer through RS232 port. At the same time, it also provides features to check the data's of year, month, day, hour, minute, second directly. The recorder can be configuration with OPC server, SCADA system and other professional software with MODBUS-RTU communication protocol through RS485 and RS232 port, plug and play, easy and flexible. PC supported data analysis software can print the data in curve and output Excel format for further analysis.

The rapid production rewards of precision bearings

Today's motion control equipment faces tougher challenges than ever before. Conveyors, and packing, sorting, and other positioning equipment often operate 24 hours a day, seven days a week. As demand for faster product shipments increase, manufacturers have also turned up the speed of their equipment. Making these operational changes means hardware wears faster, loses positional accuracies and can also increase the noise levels in most factories, warehouses, and distribution centres with implications for production staff.

It is important to choose the correct bearing for the application. The shape, size, and the choice of ball material all have an effect on the performance and life of a bearing.
