Features and Application
Features
-- Bed Type structure with fixed column
-- X and Y Axis go through cross moving table
-- Each linear motion axis use imported rectilinear rolling guide, ball screw and
servo motor.
-- Enlarge the span of guideway on Y axis furthest, eliminate the gravity tips during
X axis moving, so that ensure the stability and rigidity of machine;
-- The column is herringbone to enlarge the section size, and ensures the
construction and combination rigidity.
-- ATC system is fixed on the column, realizing automatic tool change.
-- High quality specialized bearings are used to main spindle, and all components
of spindle are no rotation vibration after strict motion balance. Tool storage uses
steel ball collet and disk spring to get tools tied and untied. Pulling force is from
disk spring. Unclamping force is from cylinder.
-- The synchronous dentiform belt is transferred between spindle and motor, the
transmission ratio is 1:1;
-- Various combination of shanks and rivets can be used to spindle
-- The guide way and ball screw are lubricated automatically by thin oil;
-- Two automatic chips conveyor, interior and exterior and are applied. Interior
screw chip conveyor, which makes machine body structure reasonable and
ensures construction rigid. Exterior chip conveyor is raddle type placed in the
rear part of machine.
-- The machine surface is equipped with closed protective cover with cocoon and
dual-door. Stainless steel shield are used on all guideways.
-- Two electric cabinets are combined with main body of machine as one,
unnecessary to disassemble during transportation or installation.
-- Modularization structure design guarantees flexible configuration with kinds of
special options.
-- Various sensor, closed loop control laser scale and rotary table can be installed
optionally;
Application
BV55 serious vertical machining centers use CNC system provided by professional
suppliers. Each linear motion axis, spindle as well as additional rotation axes are
driven by servo motors, 3-axis ganged, milling, boring, drilling and rigid threading,
which is suitable for light and general processing. Digital precision positioning can be
achieved. With motion axes plugging and ganged, processing large screw and
curved surface can be realized. Various working procedure of rough and précised
machining can be achieved with one-time clamp on the same machine tool.
Meanwhile, multiple typical cycle program is installed in the NC system as options
during processing. Pre-set program controls cutting, coolant supply, and tool change,
etc. In the process of tool change, air will be blown from spindle center automatically
to keep shank and taper-bore clean. Clips produced by cutting can be cleaned to the
chip collecting cart through interior and exterior chip conveyor.
