Features
The GSK M7132 Hydraulic Surface Grinder Machine is designed for precision surface grinding of steel, iron, ceramics, non-ferrous metals and other industrial components. Available with 1000 mm, 1600 m and 2000 mm worktable lengths, the M7132 series covers different workpiece sizes while maintaining the same 320 mm table width and 350 mm grinding-head cross travel.
With a 5.5 kW spindle motor, 350 × 127 × 40 mm grinding wheel and 1440 rpm wheel speed, this hydraulic surface grinder is suitable for machine shops, mold manufacturers, automotive component production and general metalworking applications requiring consistent flatness and surface finish.
Under the specified machine conditions, the M7132 provides a processing accuracy of 0.015/1000 mm and a surface roughness of Ra 0.63 μm.
The lateral movement of the grinding head is driven by a hydraulic motor and can also be operated manually when required.
This combination gives operators the efficiency of hydraulic movement while retaining manual control for setup, adjustment and specific grinding operations.
For workshops processing repeated batches of flat components, the hydraulic system helps reduce repetitive manual operation and supports more consistent machining.
A dedicated 0.37 kW rapid-lifting motor provides quick vertical positioning of the grinding head.
The rapid lifting function reduces non-cutting adjustment time between setup and grinding, making the M7132 hydraulic surface grinder more suitable for regular workshop production than machines that depend entirely on manual vertical adjustment.
Fine grinding requires controlled wheel positioning.
The M7132 grinding head provides:
● 0.01 mm vertical movement per handwheel division
● 1.00 mm vertical movement per handwheel revolution
● 400 mm maximum vertical travel
This allows operators to make controlled adjustments when approaching the final grinding dimension or surface condition.
All three M7132 configurations use a 5.5 kW spindle motor with a 350 × 127 × 40 mm grinding wheel running at 1440 rpm.
Keeping the same grinding-head specification across the three models makes model selection primarily dependent on required worktable length, longitudinal travel, installation space and workpiece size rather than a completely different grinding system.
The machine screw is manufactured from special alloy steel and undergoes controlled machining and heat treatment.
The purpose is to improve wear resistance and support stable machine adjustment during long-term industrial use.
The lifting mechanism and triangular support use an eccentric design that facilitates adjustment and maintenance.
For production workshops, easier mechanical adjustment can help reduce maintenance difficulty and support longer machine service life.
GSK offers three M7132 hydraulic surface grinder configurations.
| Model | Worktable Size | Longitudinal Travel | Total Motor Power | Oil Pump Motor | Net Weight |
|---|---|---|---|---|---|
| M7132×1000 | 1000 × 320 mm | 1100 mm | 9 kW | 3 kW | 3500 kg |
| M7132×1600 | 1600 × 320 mm | 1700 mm | 10 kW | 4 kW | 3550 kg |
| M7132×2000 | 2000 × 320 mm | 2100 mm | 12 kW | 5.5 kW | 3600 kg |
Choose the M7132×1000 when a 1000 × 320 mm worktable and 1100 mm longitudinal travel are sufficient for your parts.
Its shorter machine footprint also makes it easier to integrate into workshops with limited installation space.
The M7132×1600 extends the table length to 1600 mm and longitudinal travel to 1700 mm.
It is a practical option for workshops processing longer molds, plates, fixtures and machine components while retaining the same 320 mm grinding width.
For long workpieces, the M7132×2000 provides a 2000 × 320 mm table and 2100 mm longitudinal travel.
Its oil pump motor increases to 5.5 kW and total motor power to 12 kW to match the larger machine configuration.
When requesting a quotation, provide GSK with your workpiece dimensions, material and required surface finish so that the appropriate M7132 configuration can be selected.
The M7132 metal surface grinding machine can be used for surface grinding of:
Steel components
Iron parts
Ceramic components
Non-ferrous metal parts
Mold components
Machine parts and fixtures
Grinding performance depends on the workpiece material, grinding wheel selection, machining allowance and required finish. These factors should be confirmed before production setup.

The M7132 is a hydraulic surface grinder designed around hydraulic and manual machine operation. It should not be confused with a CNC surface grinding machine.
Choose the M7132 when your priority is:
Reliable surface grinding for regular workshop production
Hydraulic grinding-head movement
Manual control for setup and fine adjustment
Three worktable lengths for different part sizes
Lower operating complexity than a full CNC grinding system
If your application requires programmable grinding cycles, CNC-controlled feed or a higher level of automatic process control, GSK also offers Hydraulic CNC Grinding Machines such as the MYK series.
This distinction is important when selecting a surface grinder: CNC automation should be chosen according to the actual production process rather than simply adding CNC control where conventional hydraulic operation is sufficient.

The M7132 is designed for precision surface grinding of suitable steel, iron, ceramics and non-ferrous metal components. Typical applications include machinery parts, automotive parts, fixtures, magnetic steel components and mold parts.
The main difference is worktable length and longitudinal travel.
M7132×1000 has a 1000 × 320 mm table and 1100 mm longitudinal travel.
M7132×1600 has a 1600 × 320 mm table and 1700 mm longitudinal travel.
M7132×2000 has a 2000 × 320 mm table and 2100 mm longitudinal travel.
All three models use a 5.5 kW spindle motor and 350 × 127 × 40 mm grinding wheel.
The specified processing accuracy is 0.015/1000 mm for all three M7132 configurations.
Actual grinding results also depend on workpiece material, grinding wheel, setup, machining allowance and operating conditions.
The specified surface roughness is Ra 0.63 μm.
The final result depends on the grinding process, wheel selection, workpiece material and operating conditions.
No. The M7132 is a hydraulic surface grinder rather than a CNC surface grinding machine.
For applications requiring CNC-controlled grinding cycles and programmable operation, GSK also offers Hydraulic CNC Grinding Machines in its MYK series.
Selection should primarily be based on your maximum workpiece dimensions, required longitudinal travel, available installation space and production requirements.
Send GSK your workpiece drawing or dimensions if you are unsure which model is suitable.
Yes. GSK supports OEM and ODM requirements. Project-specific details should be confirmed before production.
GSK provides an 18-month warranty for its machine tools.
