| CNC Lathe |
| Performance Introduction |
| SPINDLE: |
| The front and back of the spindle adopts the original Japanese NSK high precist slant-angled ball bearings. |
| To it proper pretightening force is given,matching with the optimum skip distance and the box-type |
| spindle box. Thus the spindle has high rigidity and is capable to operate at high speed. |
| TAILSOCK: |
| The rotary arbor-type tailstock with high speed and high precision guarantees the turning centering.The |
| arbor bearings are all imported from NSK in Japan.The sleev can be expanded and contracted by |
| program control. The taistock can be wholly moved by the saddle pulling. |
| 60° SLANT BED: |
| The bed and the base are block mold. 60 slant bed ways can bear larger load area. It has better rigidity |
| and absorption of vibration. It can keep the high precise turning and excellent precision. |
| Main Features |
| ◇ DL-20M CNC Lathe is our latest production,with is 2-axis parallel,half-closed loop NC lathe.The |
| NC system is FANUC 0i-TA. It is driven by AC servo motor. It is ideal for turning of various |
| shafts(within 260mm) and discs(widthin 380mm) |
| ◇ Precise,rapid,longitudinal and transversal driven: The machine adopts the THK ball screw and plastic |
| skin guideway which are efficient,precise and good axial rigidity. It eliminates the clearance of return stroke |
| and makes the tool carriage move rapidly and steadily. It also has high positioning accuracy. |
| ◇ Independent chip convey and cooling systems |
| ◇ Sold Spindle supported by Hi-speed angular bearings make an ideal design for heavy duty high |
| speed turning．The powerful spindle motor can perform full-power cutting from medium to high speed |
| at top speed of 3500 RPM．High speed cutting can be performed with the newest technology tooling such |
| as ceramic or cremet． |
