Si Da Precision will exhibit new products for spindle moving automatic lathe

Sida Precision has developed a new product for spindle-moving automatic lathes - "ECAS-20T typeA" and "ECAS-20T typeB". It will be exhibited at the "EMO Hannover 2007" (Hanover International Machine Tool Show) held on September 17-22, 2007, and is scheduled to be launched in March 2008. The machining diameter is up to 20mm and the movement of the spindle table is up to 350mm. The number of spindle revolutions is 10,000 rpm.

The front and rear spindle motors of the ECAS-20T have the same output power, both of which are 3.7 kW (continuous). In this way, it is possible to perform simultaneous turning, milling, beveling, and deep hole machining using an oil hole drill on the front and back sides. In addition, the typeB can also control the rear spindle table up and down with respect to the center of the spindle, so that the eccentric complex shape component can be grasped.

The front of the new product is equipped with a tower-type tool magazine controlled by the left and right 2-axis (X/Y axis) of the spindle center. The left and right hexagonal rotors can be used for simultaneous turning and milling. In addition, the tower type magazine on the back side can also be processed by 2-axis (X/Y axis) control, so the processing time of the front and back sides can be shortened. The front and back turrets can be equipped with a total of 8 tools including ferrules, sleeves and rotary cutters.

The fast feed rate is 30m/min, which is 1.7 times that of the old model. The use of the CNC function reduces the calculation time of the spindle, thus shortening the non-cutting time. In addition, the switching time and calculation processing time between the control systems are shortened. In this way, the processing time is 30% shorter than the old model "ECAS-32T".

The new product is equipped with a spindle cooling unit that suppresses thermal deformation caused by heat generated by the spindle. By using the cutting oil cooling device, thermal deformation caused by the heating of the rotary cutter and the temperature rise of the cutting oil is suppressed. In addition, by using an energy-saving hydraulic device, the standby power consumption is reduced. Compared to the old model, the energy consumption per unit component is reduced by up to 37%.
