Details:
A, the main purpose of the horizontal machining center, and use scope:
Mainly through horizontal machining center CNC system, servo drive based motion control of machine tools, the main characteristic of the structure is the main shaft level Settings, random equipped with rotary knife library, workpiece in machining center after a clamping, machine tool numerical control system can control, according to the different processing working procedure, automatic selection and replacement of cutting tools, automatically change the spindle speed, feed rate and the trajectories of all meet relative to the workpiece and other auxiliary functions, complete the multistep automatic processing, especially suitable for box and complicated structure processing, can be widely used in machine tools, automotive, aerospace, Marine and other industries more bottle parts processing. Machine tool appearance figure is shown in figure 1.

Three, horizontal machining center of the drive system is introduced:
1, the machine tool main drive system
The machine tool main drive spindle motor through the synchronous belt wheel synchronous belt attached directly to the main shaft synchronous belt wheel. Using ac spindle motor spindle motor. Machine tool main drive system structure diagram as shown in figure 3.

2, feed drive system
X, Y, Z three coordinates of feed movement driven by servo motor, will directly by elastic coupling motion is passed to the screw, again by ball screw lieutenant rotation movement into linear motion. The axial feed transmission structure and bearing section as shown in figure 4.

Four, the installation of the horizontal machining center:
Machine installation location should avoid direct sunlight, away from heat and dust concentration bigger place, at the same time must have a strong solid foundation. If the installation location near a large source of vibration, response to take appropriate measures of vibration isolation. When the machine installation based or concrete can be directly mounted on the ground, also can use anchor bolt fastening in the base or the base concrete on the ground. If land bolt fixed machine, the installation of anchor bolt refer to shown below (figure 6). Machine after the installation, use clean petrol or kerosene soaked cotton yarn, carefully wipe antirust oil, and then coated with a layer of oil.
Five, horizontal machining center of maintenance:
1, daily
Horizontal machining center machine tool use:
The machine can be used in aerospace, automobile, internal combustion engine, electrical appliances, general machinery, precision machining,
More suitable for parts working face milling, drilling, boring, reaming, tapping, more than two dimensions, such as machining,
Has a complete enclosure in a clamping hole the good performance of system and graphic processing, is particularly suited to body hole, switching boring processing

The main structure:
The machine for single mast fixed, table structure. Is mainly composed of lathe bed, column, beam, transverse sliding table, table, spindle, screw, lubrication system, cooling system, CNC operation panel and electric control system and other parts.
1. The main components of the optimization by finite element analysis, the main cast iron with high strength cast iron microstructure stability, after aging, sandblasting, tempering process ensure the stability of precision machine tools use for a long time.
2. Across gantry type structure, the structure of three-dimensional variable diameter optimization, reduce the powerful when cutting vibration of machine tool, machine rigidity is better.
Beam the ladder form design, strong rigidity structure suitable for strong cutting.
3. High speed high rigid spindle spindle unit combined with servo motor; X/Y/Z adopt servo motor with high torque.
4 X/Y/Z adopt Taiwan high precision ball screw with high strength Japan NSK ball screw pair dedicated bearing with high precision imported lock.
5. X/Y guide line trajectory design adopt Taiwan roller rail line of silver (4 X axis line rail), Z axis for rail, fixed surface using ultra high frequency quenching process after precision grinding; Sliding surface with high strength wear resistant material plastic belt post processing.
The model for the column type horizontal machining center machine (budget) 24 t disc knife library.
Standard configuration:
Taiwan new generation system disk knife library Taiwan screw domestic horizontal back workbench.
Japan NSK bearing pressure cylinder lock nut and other Taiwan Taiwan linear guide nitrogen balance system.
