Features:

Rigid Machine Structure
．The machine structure is manufactured from high quality Meeharite cast iron, heat treated and stress relieved before machining.
．Sideways are high frequency hardened and precision ground. Maximum material stability for deformation-free and outstanding wear resistance.
Precision Spindles
．The grinding wheel spindle and the regulating wheel spindle are precision machined from Nickel Chromolybedenum alloy steel (SNCM-220). Also, they are subject to various treatments such as: normalized, tempered and carburized hardening. Then, the spindles are thru sub-zero treated – under zero degrees, precision ground and precision machined.
．The inside of spindle is tempered to hardness HRC 25°~30°, while surface hardness reaches over HRC 62. The precision ground spindle is excellent for heavy-duty machining and features powerful torque, long service life, deformation-free and maximum wear resistance.
Slide Table
．Upper slide swiveling is easy and accurate to adjust for making the machine suitable for infeeding grinding. Also, it allows grinding for a varied diameter fo workpieces. The Upper slide with +5°~-5° swiveling allows taper grinding by using infeed grinding mode.
．With thrufeed grinding, the Upper slide provides a surface contact adjustment between the workpiece and grinding wheel. Swiveling adjustment range is +5°~-3°.
．Dovetailed slideway on the upper slide features smooth and accurate feeding and is lubricated by a centralized lubricator.
．The bottom slide moves on “Λ” shaped and double-wedged ways.
The slideways are hardened and precision ground. They feature smooth movement and properly protected to prevent dust from entering. Micrometric feed adjustment unit is 0.001 mm to meet high accuracy requirements for all workpieces.
Feed Screw
．The feed screw is manufactured from Nickel Chromolybedenum alloy steel (SNCM-4). It is also normalized, high frequency hardened treated and precision ground.
．Specially-designed adjustable nut features easy adjustment, high feeding accuracy, smooth motion and excellent wear resistance.
Automatic Unloading Equipment for Thrufeed Grinding (optional)
．Designed for automatic unloading for round tube and bar stock, this equipment can avoid workpiece surface scratching. It is also suitable for online operation while performing two to three grinding processes. The conveyor is easy to adjust. Equipped with a parts tray for convenient parts collection after grinding.
Lubrication System
．The automatic lubricator provides lubrication to the grinding wheel spindle.
．All slideways are lubricated by a centralized lubrication system, ensuring proper lubrication and feeding accuracy.
Automatic Loading Equipment for Thrufeed Grinding(Optional)
．Suitable for automatic loading operation for round tube and bar stock.
．Equipped with a storage tray for automatic workpiece infeed.
．It eliminates manual workpiece infeed while enormously increasing total efficiency.
Pressure Switch
．When starting the grinding wheel and regulating wheel spindle, this pressure switch all ows starting only when oil enters into bearings thereby providing safety protection for the spindle bearings.
Hydraulic Cooling Device
．The lubrication system for bearings on grinding wheel spindle, regulating wheel spindle and hydraulic system are driven by the same hydraulic pump. A cooling fan is equipped for effectively reducing oil temperature.
Dresser for Grinding Wheel and Regulating Wheel
．Dresser structure is manufactured from alloy cast iron and is heat treated for wear resistance.
．Hydraulically operated dressing motion.
．Variable dressing speed.
．Dresser stand for regulating wheel can be adjusted to suit workpiece requirements, assuring high cylindrical accuracy.

PC-18S/1810S/1812S/20S

Features:

Feed Screw
‧The feed screw is manufactured from Nickel Chromolybedenum alloy steel (SNCM-4). It is also normalized, high frequency hardened treated and precision ground.
‧Specially-designed adjustable nut features easy adjustment, high feeding accuracy, smooth motion and excellent wear resistance.
Slide Table
‧Upper slide swiveling is easy and accurate to adjust for making the machine suitable for infeeding grinding. Also, it allows grinding for a varied diameter of workpieces. The Upper slide with +5°~ -5° swiveling allows taper grinding by using infeed grinding mode.
‧With thrufeed grinding, the Upper slide provides a surface contact adjustment between the workpiece and grinding wheel. Swiveling adjustment range is +5°~ -3°.
‧Dovetailed slideway on the upper slide features smooth and accurate feeding and is lubricated by a centralized lubricator.
‧The bottom slide moves on "Λ" shaped and double-wedged ways. The slideways are hardened and precision ground. They feature smooth movement and properly protected to prevent dust from entering. Micrometric feed adjustment unit is 0.001 mm to meet high accuracy requirements for all workpieces.
Dresser for Grinding Wheel and Regulating Wheel
‧Dresser structure is manufactured from alloy cast iron and is heat treated for wear resistance.
‧Hydraulically operated dressing motion.
‧Variable dressing speed.
‧Dresser stand for regulating wheel can be adjusted to suit workpiece requirements, assuring high cylindrical accuracy.
Automatic Loading Equipment for Thrufeed Grinding (Optional)
‧Suitable for automatic loading operation for round tube and bar stock.
‧Equipped with a storage tray for automatic workpiece infeed.
‧It eliminates manual workpiece infeed while enormously increasing total efficiency.
Automatic Unloading Equipment for Thrufeed Grinding (Optional)
‧Designed for automatic unloading for round tubes and bar stock. This equipment avoids workpiece surface scratching. It is also suitable for online operation while performing two to three grinding processes. The conveyor is easy to adjust. Equipped with a parts tray for convenient parts collection after grinding.
