Product Performance：

DY-850L Vertical machining center adopts advanced design concept and is developed by our engineers with rich experience for many years, which is suitable for China manufacturing and processing industry with excellent cost performance. And after million times of testina, the equipment has gained market recognition and customer favor. 

1、 Precision resin sand casting： The casting is made of

HT300 precision resin sand and cast with high quality cast iron,

so that the machine tool can obtain high rigidity and long-term 

Stable precision.And after sufficient secondary processing (tempering, vibration aging) for the machine is not easy to

deform in the perennial use of the machine, can ensure the 

Stability of the machine.

2、Highly integrated intelligent electric panel：It is

developed and and uparaded on the basis of traditional electric 

cabinet. It has the advantages of simple wiring, strong dry

tightness  resistance, low failure rate, high reliabilitv and

high operation safety factor.

3、 Advanced numerical control system：This product adopts

FANUC of Japan system, Japan Mitsubishi system, 

Huazhong system, Xindai system and other well-known systems, 

the system uses modular structure control panel highly 

integrated,high reliability, simple and convenient operation.

4、 Famous spindle in Taiwan：The famous spindle imported from 

Taiwan is adopted, which has the advantages of high 

reliability,low noise, small vibration and high precision.It

is suitable for high precision,high rigidity and high speed

machining.

5、High-speed servo tool magazine：High-speed servo tool magazine realizes high-speed tool change, fast and stable, greatly reduces the non-machining period,and greatly increases the machining efficiency.  

 6、Guide rail and lead screw： Class C3 high-rigidity pre-tightening ball lead screw of famous brand in Taiwan is adopted, which can realize high-precision position control and ensure the stability of the machine tool.The linear guide rail adopts the P grade guide rail of Taiwan or Germany, which improves the axial running speed of the machine tool and ensures the positioning accuracy of the machine tool.
