Product Description

 
 main structural features
1. The bed is made of high-rigidity cast iron, which is molded with resin sand and aged. The internal rib shape of the bed is reasonable and has high rigidity, which can fully guarantee the stability of the machine when cutting large diameter parts. The guide rail adopts medium frequency quenching grinding process, and the hardened layer is 2 to 3 mm deep and the hardness is above 52 HRC. In the sliding guide surface, the anti-creep rail plate and other technical measures are adopted to make the dynamic characteristics such as the stiffness and the friction damping coefficient of the feed system in an optimal state, thereby avoiding the occurrence of low-speed crawling.
2. The X- and Z-direction feeds the ball screw with high pitch and high-precision high-strength; the servo motor adopts flexible coupling and screw directly, which directly transmits the power to the high-precision ball screw, X and Z. The direction screw is sealed and sealed to ensure the cleanness of the screw and ensure the transmission and movement accuracy of the machine.
3, the use of domestic well-known brand four-station CNC vertical electric tool holder, with high precision, stable rotation, simple movement and so on.
4. The spindle head of the machine tool adopts a symmetrical structure to make the thermal deformation uniform and avoid the offset of the center of the spindle. The main motor transmits power to the main shaft through a shifting mechanism such as a belt or a gear. In the design of the headstock, taking into account the improvement of the precision of the spindle and the enhancement of rigidity, some effective measures have been taken, such as: the spindle is matched with the inner ring of the bearing, the hole of the box is matched with the outer ring of the bearing, and the spindle bearing is pre-tensioned. In addition, the gears in the spindle head are quenched and grounded to ensure accurate transmission and low noise. The well-assembled spindle has the characteristics of low temperature rise, small thermal deformation and high precision, which can keep the precision of the spindle relatively stable during long-term operation. Spindle box spindle bearings use precision spindle bearings. In order to reduce the thermal deformation of the machine tool, the heat dissipation measures are added, and the head box lubrication is lubricated by the oil bath.
5, the standard configuration provides a wealth of CNC functions, full-featured, easy to operate, accurate and reliable. Such as: LCD display, various cycle functions, tool compensation, program storage and editing, metric conversion.
6. It adopts advanced centralized automatic lubrication device, automatic intermittent lubrication with timing and quantity, and the work is stable and reliable.
7. The outer machine protection adopts semi-closed mechanism design, reasonable layout, pleasant appearance, safe and reliable, and good protection effect.
