The perfect combination of the structure design technology of the thermal stability, whole machine’s thermogenic management technologies and thermal compensation technologies, has guaranteed the further improvement of the precision stability of the machine tool.

Indexing action is kept reliable and stable dependent on drive of large-diameter sliding surface and double gears 90°locating pins independently researched and developed by Dawei guarantees high precision. In addition hydraulic and T-bolts are used for solid clamp. Furthermore, backboard is used to prevent float of worktable under strong clamp of hydraulic and T-bolts.

The worm gear drive is used in the mechanical transmission part of the slewing table. Compact structure, stable transmission, vibration, shock and noise are small. The large transmission ratio can be obtained by single stage transmission, which is beneficial to the realization of the indexing requ9ired by the rotary table.

Automatic tool changer is composed of tool magazine and tool changing arms. Automatic tool changer is installed separately from machine tool with the purpose of preventing adverse influences of vibration during running of automatic tool changer and other reasons of precision. Tool selection adopts the method of fixed address in the shortest path. All tools return to original position, therefore, the problem of collision between large-size tools is only considered in initial installation. Two-way tool magazine adopts the shortest path.

Enlarge the speed regulation range to improve the energy saving effect. Use the ration pump and servo motor to reduce the noise greatly.

Maintenance items of machine tool such as lubrication control units are centrally installed at the back of machine tool with convenience for check during daily maintenance.

Widening pedals of operators and shortening distance between workpieces and operating panel are helpful for improving efficiency of aligning and clamping operations.
