| The newly developed Double Spindle Vertical Grinder from Sigma is an innovative design concept for precision grinders. |
|
Bridge-type structure features high rigidity and stability. |
|
Double spindle configuration |
|
German IMT high speed spindle |
|
Advanced CNC control |
|
Linear guideways on 4 axes |
|
Servomotor drives on 4 axes |
|
|
| |
| Rigid Bridge-type Construction |
|
The bridge-type machine construction guarantees the maximum stability for grinding operation. |
|
The structural parts are manufactured from high quality Meehanite cast iron with scientific rib reinforcement, and stress relieved for optimal rigidity and stability. |
|
Wide space in the machine working area increases convenience of workpiece loading and unloading. |
|
Fully enclosed splash guard. |

 |
| Direct Drive on Three Axes |
|
The X, Y and Z axes traverses are driven by servo motors which directly drive ball screws via couplings. These assure outstanding positioning accuracy. |
|
|
 |
| Z, A Double Spindles |
|
The Z, A- axis are individually driven by 3.5 kW motors. The specially designed double-spindle configuration greatly upgrades machining efficiency and accuracy. |
|
|
 |
| Table |
|
4 T-slots on the table allow for mounting jigs. Upon request, the manufacturer can design and manufacture jigs to meet customers' specific parts requirements. |
|
Jigs are optional equipment. |
|
|
 |
| Three Blocks on Z Axis |
|
Each linear guideway on Z-axis is equipped with three blocks to effectively upgrade stability of wheel head during grinding. |

 |
| Double Vertical Wheel Spindles |
|
The double vertical spindles can be mounted with internal and external grinding wheels. This permits inside and outside diameters of a workpiece to be ground at a time, thereby assuring highly accurate concentricity. |
|
Both spindles can be operated together or individually. |
|
All spindle motions are controlled by computer for convenience and efficiency. |
|
|
|
| |
 |
| Horizontal Vertical Spindles |
|
The vertical spindle is quickly converted to a horizontal spindle. |
|
The horizontal vertical spindle is suitable for outside diameter, inside diameter, surface and form grinding. |
|
|
|
| |
 |
| German IMT Spindle |
|
The spindle speed is specified by customer. |
|
Maximum spindle speed is up to 140,000 RPM. |
|
|
|
|
| |
|
| |
 |
| C Axis Rotary Table (Optional) |
|
Suitable for various shapes of workpiece, such as circular and prismatic shapes. |
|
Rotary table diameter 170 mm. |
|
Min. setting unit : 0.001. |
|
|
|
| |
 |
| Rotary Table (Optional) |
|
Equipped with D.D. motor to ensure the best circularity and motion smoothness. |
|
Rotary table diameter 350 mm. |
|
|
|
| |
 |
| Heat Exchanger for Control Cabinet |
|
The control cabinet is equipped with a heat exchanger to ensure consistent temperature in the control cabinet, providing maximum stability of control performance. |
|
The heat exchanger also provides effective protection for electronic parts, controller and motor driver and extends the service life. |
|
|
|
| |
| Air Powered Spindle / Rotary Dresser (Optional) |
|
|
|
|
| |
|
| |
 |
| End Face Touch Probe (Optional) |
|
The touch probe is used for fast and convenient measurement for reference point of end face. |
|
|
|
| Water-cooled Cooler (Optional) |
 |
|
|
| |
 |
| Movable Coolant Tank |
|
The front mounted, movable coolant tank is easy to clean or replace coolant. |
|
The coolant system employs a special high pressure coolant pump, featuring excellent cooling and chip flushing. |
|
|
|
| |
 |
| Swing-type Control Panel |
|
The control panel can be swung to any angle and moved to any position for maximum operational convenience. |
|
|
|
| |
 |
| Control System Meets European Standards |
|
The control system consists of top quality electronic components which comply with European safety requirements. |
|
The interior of control cabinet is dust-proof and fluid-proof. |
|
The control system has a self-diagnostic function and warning light for clear identification. |
