Summary:

SJ-1370 vertical machining center has a strong overall structure and the machine structure has been optimized by finite element analysis for greater rigidity and structural stability. Ribbed head design: the internal ribbing is thickened and enlarged to enhance structural rigidity and significantly improve machining stability. Machining characteristics: with the full performance of both drilling and tapping centers, it is a composite machining center.

Introduction:

SJ-1370 vertical machining center’s X/Y/Z three axes are servo direct control semi-closed loop vertical structure, three axes are high rigidity rectangular guide rail, guide rail load, wide span, high precision, sliding surface paste plastic, spindle is a servo motor through the synchronous belt drive, can achieve a variety of discs, plates, shells, cams, moulds and other complex parts in one clamping, can complete drilling, milling, boring, expansion, reaming, rigid tapping and other processes processing, suitable for a variety of small and medium batch production, can meet the processing of complex, high-precision parts.

Machine Performance Features

• The machine tool casting adopts the Japanese casting process standard HT300, with high strength, low deformation, no resonance. The uniform density of the material and the reasonable distribution of reinforcement bars ensure the stability of the machine's steel and precision for long-term use. Three axes of roller line rail, Z axis six sliders (as shown), more enhanced cutting dynamic steel.

• High-precision spindle: Taiwan OKADA/KENTURN precision short-nose BT50 spindle, with high rigidity. The spindle and motor drive by belt, which can reduce the transmission noise and heat generation. The spindle adopts precision grade Japanese or German bearings, high speed, high precision and good heavy load performance. The spindle head has a built-in independent cooling system to control spindle heat and reduce spindle thermal extension, ensuring the accuracy of the machined workpiece.

• The three axes guide rail all adopt Taiwan HIWIN/PMI C3 grade high precision and high strength ball screw. High feeding speed, drive motor is directly connected to the screw through the flexible coupling, with small clearance, thus ensuring the positioning accuracy and repeat positioning accuracy of the machine.

• Adopt original Taiwan OKADA or TFD BT50-24T disc type ATC (Tool magazine). Fast tool change speed, good stability, safe and reliable

• Machine with enclosed full protection sheet metal for safe operation. The enclosed inner guard can effectively protect the ball screw, guide rail and extend their suing life.

• Adopt advanced FANUC MF absolute operation CNC system, adopt high power FANUC servo motor, absolute encoder, good stability, support four-axis linkage, fast computing speed, have hand wheel simulation function to prevent tool collision.

• Automatic lubrication system, the use of centralized pressure divider distribution oil injection, timing, quantitative automatic oil supply, to extend the service life of the guide rail screw.

• Accuracy inspection conforms to JB/T8771.2-1998 machining centre Part 2 geometric accuracy inspection and JB/T8771.4-1998 machining centre Part 4 accuracy inspection standards.
