Key Benefits
Why Workshops Buy This Machine
Keeps the Work In House
Operations that would otherwise be sent out stay on your floor, which is what removes parts sent out for finish grinding after every heat treatment batch.
Parameters You Can Plan Around
The published data for this model lists max.grinding size(lxwxh) of mm 1000*200*400 100*320* 400 1000*400*400 1000*500*500 and table longitudinal travel of mm 1050 1050 1050 1300.
Documented and Supported
The machine ships with an operation manual and a named contact who answers on WhatsApp, so commissioning questions do not go unanswered.
Matched Tooling Available
Chucks, arbors, vises and measuring equipment from the same supplier, quoted with the machine instead of chased separately.
Application Scenarios
Where the Surface Grinding Machine M7120/M7130/M7140 Earns Its Place
- Finishing shafts after heat treatment
- Surface grinding of dies, plates and fixtures

Problems It Solves
Three Situations This Machine Fixes
Subcontracting Delay
Sending this operation out adds days to every job. Running it in house on the Surface Grinding Machine M7120/M7130/M7140 removes the queue you do not control.
Parts No Longer Available
When an original part cannot be bought, the only route left is to make or restore it, which needs the capacity this machine provides.
Unpredictable Quality
Work done on improvised equipment varies between operators. A purpose built machine with published parameters makes the result repeatable.

Materials Manufacturing and Quality Control
How the Machine Is Built and Checked
Casting and Machining
Beds, columns and housings are machined in the group's production workshop on conventional and CNC equipment.
Assembly
Assembly is done in a dedicated workshop rather than on the production floor, which keeps swarf away from fitted surfaces.
Inspection
The inspection department checks components and assemblies before the machine goes to paint. Test records per machine are TBC on request.
Paint and Packing
Painting is done in house, then the machine is rust protected, crated and prepared for the container.
Certification scope for this model is marked TBC. We attach the certificates that actually apply to the machine and destination instead of publishing a blanket claim.
Customization Options
What Can Be Changed Before Production
- Motor voltage and frequency to match your supply, stated with the order
- Tooling and workholding packages selected for your first jobs
- Model variant chosen against your maximum workpiece size
- Documentation and marking requirements for your destination, TBC per country
Send a drawing of the part you need to produce. We select the model against that drawing rather than pushing the largest machine in the range.
