*Standard accessories shall be subject to the quotation.
- 1. The slide way and ball screw can be lubricated automatically by central lubrication system. Oil flow and lubrication frequency can be set as desired. An alarm occurs in case of lack of oil.
- 2. The coolant system delivers high pressure coolant to flush chips and extend tool service life.
- 3. Mechanical and electrical are designed all in one.
- 4. FC-30 steel are used for main structures like base, spindle, saddle and tailstock, which are annealed and have no deformation.
- 5. The structure of bed is adopted high toughness Meehanite cast iron; stabilize properly parallel precision. Bed ways are induction hardened and ground.
- 6. One -piece casting base for processing capacity to be more stable.
- 7. HEADSTOCK -Spindle 4-step speed auto change
- Photo shown headstock with spindle bore 152mm(6").
- The spindle bore diameter 4” or 6 “ are supported by precision heavy duty bearings at three points.
- Equipped with hydraulic cylinder for automatic speed change, with four-speed gears speed change, each speed can be output at full horsepower, and can achieve high-precision and heavy-duty cutting.
- Gear and shaft are made of super alloy material with NSK bearings to offer durable cutting and low production noise.
- Sealed oil bath lubrication system with enforced oil supply by mechanical pump to achieve better lubrication effects.
- 8. Tailstock
- Photo shown Option : Tailstock with hydraulic quill.
- Tailstock extended quill match up with H4 turret or V8 hydraulic turret can do cutting of long workpiece.
- Depend on the requirement of client, tailstock quill can be changed to optional hydraulic quill and tailstock base with hydraulic lock bolt.
- Standard with saddle-tailstock device makes the tailstock body move smoothly and the operation is labor saving.
- Optional function of tailstock base moving motorized is available.
- 9. High quality control components
- The control circuit in the electrical cabinet consists of high-quality electronic components, featuring maximum stability of control performance and long service.
- The electrical cabinet is equipped with a heat exchanger to ensure constant temperature.
- Photo shown Option : Boring attachment
- Special customized boring attachment and boring bar can be installed on the cross slide, and the diameter and depth of the boring hole can be controlled by programming.
- Special customized bushings can be produced for different processing requirement to install different sizes of boring bars.
- According to customer needs, it can be equipped with a cooling system with coolant through center.
