What This Machine Does
The 2M9120A is a multi-grinder: one machine with both the characteristics of a universal cylindrical grinder and those of a tool and cutter grinder. It handles external grinding, internal grinding and light surface grinding, and it sharpens general cutting tools including milling cutters, reamers, pinion cutters and straight fluted hobs. Taper grinding is within its range as well, so a tapered shank or a cone seat is done on the same machine. For a small plant that is the point: rather than buying a cylindrical grinder, a tool grinder and a small surface grinder, one machine covers all three and a shop fitter only has to learn one set of controls. Machine weight is 1285kg with overall dimensions of 1630x1173mm, so it fits a normal workshop bay. Typical estimated build time for a single unit is 30 days, with larger quantities negotiated. It is aimed at small machine plants, tool workshops, repair workshops and research institutes.
Why Buyers Choose This Machine
- One machine covers external internal taper and light surface grinding plus tool sharpening
- Sharpens milling cutters reamers pinion cutters straight fluted hobs and turning tools in house
- Removes the need to buy and floor three separate grinding machines in a small plant
- Taper grinding included so shanks and cone seats are ground without a second setup
- 1285kg machine in 1630x1173mm of floor so it fits an ordinary workshop bay
- Single set of controls for the operator to learn instead of three machines
- Estimated 30 days build time for a single unit so a shop can plan around it
Where 2M9120A Universal Cutter Tool Grinder Earns Its Place
Problems It Solves
- Sending cutters out for resharpening costs money and takes tools off the shelf for days
- Three grinding machines need three lots of capital floor space and operator training
- A dull cutter run on for too long wrecks the surface finish on the parts it makes
- Taper work has to be jobbed out when the shop only has a plain cylindrical grinder
- Occasional light surface grinding does not justify a dedicated machine
- A small plant has no way to grind an internal bore without a separate internal grinder
Who It Is For
- Small machine plants that cannot justify three separate grinders
- Tool workshops sharpening their own cutters
- Machine repair workshops handling varied grinding jobs
- Research institutes of science and technology
- Distributors supplying universal grinders to small and mid-size workshops
Application Scenarios
- Resharpening milling cutters and reamers instead of sending them out
- Grinding turning tool geometry in a toolroom
- External and internal cylindrical grinding of small components
- Taper grinding of shanks and cone seats
- Light surface grinding jobs in a shop without a dedicated surface grinder
- Teaching and research work where one machine has to show several grinding methods

- Internal grinding spindle specification matched to your bore sizes
- Manual and machine markings prepared in your working language
How It Compares With the Alternatives
| M1320 and M1420 cylindrical grinders | Those are dedicated cylindrical machines with more capacity and rigidity for production diameter work; the 2M9120A trades that for the ability to sharpen cutters as well |
|---|---|
| M7120 to M7140 surface grinders | Those are built for flat work all day; the 2M9120A handles light surface grinding as one of several jobs |
| Sending cutters out for resharpening | An outside sharpening service ties up spare tooling and adds days; grinding in house means the cutter goes back on the machine the same shift |
| Buying three separate grinders | One machine and one set of controls costs less capital and floor space, at the price of not being able to run three jobs at once |
Running the Machine
Step 1
Select and fit the wheel and the holding fixture for the operation you are doing
Step 2
Set up the workhead or tool fixture and check the swivel setting against the scale
Step 3
Dress the wheel before starting the component or cutter
Step 4
For tool sharpening index the cutter and take a light first pass to confirm the geometry
Step 5
For cylindrical work rough to within allowance then spark out on the final passes
Step 6
Keep coolant on the contact where the job calls for it
Step 7
Check the ground tool or component before running the rest of the set
