Jskingston Full-Auto Surface Grinding Machine

The full-auto surface grinder adopts heavy-duty grey cast iron for its base, column and slide components, offering outstanding structural rigidity to suppress vibration and maintain stable machining flatness. It is fitted with an independent hydraulic station and GS-PLC touch control system, paired with a standard electromagnetic worktable, ideal for precision flat grinding of mould and mechanical parts with high cost performance.

X and Y axes are equipped with plastic-coated guideways to eliminate low-speed stick-slip movement. The longitudinal table uses V-flat composite guideways, while the cross slide adopts double-V guideways, ensuring reliable load bearing and excellent wear resistance. The spindle is equipped with clearance-free preloaded precision bearings for steady grinding output. The separate hydraulic unit comes with a built-in heat exchanger to control temperature buildup, eliminating thermal deformation and vibration during long continuous production

1.Three-Axis Motion System

The machine follows standard XYZ three-axis layout with differentiated drive designs for each axis:

Z Axis (Vertical Feed Axis)

Driven by an AC servo motor, the Z axis is the core of automatic cyclic grinding. It supports rapid vertical traverse and adjustable fine feed to control grinding depth accurately.

The automatic Z-axis grinding cycle works as below: the wheel descends rapidly and slows down when approaching the workpiece, then proceeds through rough grinding, fine grinding and spark-out finishing. Once the cycle finishes, the grinding head lifts automatically back to the starting position, with all processing steps configurable via touchscreen.

Y Axis (Cross Axis)

Motor-driven cross axis supports automatic reciprocating feed and manual fine-tuning via handwheel, enabling flexible lateral stock removal adjustment.

X Axis (Longitudinal Axis)

Hydraulically powered longitudinal table delivers smooth reciprocating motion for full-surface coverage. Limit stoppers are mounted on both ends to avoid accidental collision.

2. Touchscreen Control Operation System

The machine is equipped with Samsys SMART-panel IE V3 touch controller with fully visualized parameter setting, requiring no complicated programming.

Operators can freely configure core grinding parameters: rough grinding cycles & feed depth, fine grinding cycles & feed depth, and spark-out finishing times. It supports electronic handwheel magnification switching for precise manual positioning, as well as single-cycle and continuous-cycle grinding modes. One-click RUN and STOP buttons simplify routine operation.

3. Core Product Advantages

Low-friction coated guideways and reinforced V-type guide structure deliver stable load capacity and long service life.

Preloaded spindle bearing assembly reduces spindle runout, achieving consistent surface finish on steel, aluminium alloy and cast iron workpieces.

FAQ

Q1: What kinds of workpieces can this grinder process?

A1: It processes ferrous metals including steel and cast iron, as well as non-ferrous materials like aluminium alloy. It is widely used for mould plates, thin precision parts and standard mechanical components.

Q2: What is the advantage of servo motor on Z axis?

A2: The servo motor achieves ultra-fine vertical feed resolution, ensuring even material removal during rough and fine grinding, which greatly improves flatness precision for thin workpieces.

Q3: What role does spark-out grinding play?

A3: No vertical feed is applied during spark-out grinding. It removes residual grinding lines and releases internal machining stress, effectively reducing workpiece deformation after demagnetization and unloading.

Q4: How to avoid collision during automatic processing?

A4: Mechanical limit stoppers are installed on X and Y travel strokes. Operators can also set safe moving boundaries on the touchscreen to restrict the table’s moving range for double protection.
