Features of the machine tool performance and structure
Adapted to features of usage demands of domestic users, B2-K1015 and B2-K1014 CNC (universal) cylindrical grinding machines are universal and economic CNC products adopting mature functional modules and parts. They are characterized by compact structures, convenient operations, reliable quality, high cost efficient performance and etc. The machines are suitable for usages in workshop dedicated for batches and small & medium-sized volume of productions, and they basically meet the requirements of high accuracy, high efficiency and flexibility needed for modern production.
With the structural layout of mechatronics and a working area protection shield or an integral protective cover (B2-K1015), the machine tool is convenient for maintenance and in conformity with human engineering requirements.
With a structure of sleeve type large-taper hydrodynamic shafting adopted for the grinding wheel spindle, the machine tool features on its adoption of the immerse oil type lubrication, high rotary precision and good rigidity.
With two-axis linkage movement, the machine tool is equipped with worktable (Z axis) and a wheel head (X axis) driven by AC servomotor and ball screws.
The machine tool adopts a pre-fixed diamond dresser, thus realizing precise CNC dressing and automatic compensation.
The machine tool is provided with an imported or a domestic active measuring device, thus realizing the closed-loop control of grinding process.
The machine tool adopts an imported or a domestic CNC system and fully absorbs advanced technologies for modern NC typecylindrical grinding machines.
