VHT vertical turning and milling combined machining center was undertaken by Dalian Machine Tool Group Co., Ltd., and carried out modular design, dynamic and thermal compensation research, dual function turntable (torque motor hydraulic brake), A-axis swing head (mechanical swing) The development and reliability of the electric spindle) completed the development of three prototypes of Φ800mm and Φ1000mm, and preliminary application verification.
The research and development of large chain tool magazines and high-speed disk magazines and automatic tool changers was undertaken by Dalian Machine Tool Group Co., Ltd., and system design research, key parts processing technology and reliability test were carried out. 18 test benches and large tools were built. The library can be configured with 40-120 tools, with a single tool weighing 30kg and a tool change time of 5-10s. The high-speed disk magazine can be equipped with 30-48 tools and a tool change time of 4.5s. Dalian Machine Tool Group has formed a mass production of tool magazines and self-supporting capabilities of the group.

A prototype was developed to complete the key part of the heavy-duty marine diesel engine of Shaanxi Diesel Heavy Industry Co., Ltd.
Description:Braided Packing includs many kinds such as PTFE,Graphite,Kevlar fiber,Carbon fiber etc,they are the perfect material for door seals or caulking for ovens, furnaces and boilers, expansion joints, cable or pipe wrapping, high temperature seals or gaskets. These products have been widely used in welding, foundry works, aluminum and steel mills, boiler insulation and seal, exhaust systems, shipyards, refineries, power plants and chemical plants. Braided Packing are also used as the core in tadpole gaskets. The three different styles are designed to fit different application needs: twisted rope is a soft rope, while square and round braid are more dense and solid.
PTFE Braided Packing especially suitable for sealing flange connections, pip systems, hydraulic and pneumatic systems, etc. In addition, it's a good ideal for seals in glass, enamel and plastic flanges, vessels and special shaped sealing surface.Features
Clean, non-contaminating and Long maintenance free service life
Minimal shaft wear and leakageSave money and time.
