is optional.
1. Main material and stiffened plate layout
(1) Castings: bed, worktable, column, cross beam, Y axis carriage,
ram etc. are made of high strength, low stress casting iron and
resin sand molding process, and after heat treatment, the internal
stress is eliminated, to get good overall stable structure. With
the characteristics of high strength, good rigidity, small heat
effect and excellent seismic performance, machine’s overall
precision is guaranteed for a long time. To prolong the service
life.
(2) Stiffened plate: Use FEM 3D finite element analysis technology
to optimize the design and arrange the reinforcement plate
reasonably, so as to maintain the overall stability of the
structure for a long time, so as to ensure the overall accuracy and
prolong the service life of the machine in long term.
2. Spindle unit
(1) Spindle drive: FANUC high power, high torque generalized
spindle motor, and high precision Taiwan spindle synchronous belt
drive.
(2) Spindle rigidity: Spindle is located at the center of the Z
axis ram, and the core rod grinding process with the ram inner hole
has excellent rigidity to meet the strong cutting. Spindle tool
loosen and broach: Use a special hydraulic cylinder to complete the
spindle automatic tool loosening, spindle automatic broach is
completed automatically by the butterfly reed.
3. CNC axis servo drive and guide track composition
(1) X, Y, Z axis direct connection drive: FANUC AC servo motor, and
large torque synchronous belt pulley, and high precision JIS-C3
ball screw (ball screw and nut to take pre tightening, full travel
check, clearance elimination) transmission structure, to realize X,
Y and Z three way feed.
(2) X, Y axis guide rail: Use high rigid roller linear sliding
guide rail, has the advantages of good dynamic characteristics,
large load bearing capacity, high running accuracy, no crawling at
low speed, and small friction resistance.
(3) Z axis guide rail: Hard guide rail. Through the high frequency
quenching heat treatment process on the slideway guide rail
surface, the surface roughness and surface hardness are obtained
through rail grinding, and then the sliding guide is made with the
Y axle trailing board (polytetrafluoroethylene PTFE).
FANUC system can open AICC high speed, high precision, five axes
