Optional Attachment for M-40
1. Face Mill Grinding Attachment
This attachment comprises a base, swiveling horizontally with respect to the table and w workhead swivelling at 15 degree angle. This construction simplifies greatly the setting of elevation and depression angle. Furthermore, rugged design gives the M-40 the capacity for grinding large cutters and tools.
| Capacity | |
| Max. dia. of cutter | 457mm |
2. Radius Grinding Attachment
This is ideal for sharpening the radii of ball end mills and styli. In consists of the two slide bases, each with micrometer adjustment and a workhead having a MT No. 5 or No. 12 taper hole spindle. Indexing of straight flute cutters is possible using an index plate mounted on the back of workhead.
3. Radius Grinding Attachment
This is suitable for corner radius grinding of face mill and shell end mills. The position for grinding start is set by the micrometer to eliminate grinding error.
| The grinding capacity | 0 through 1″ radii (0 through 25mm) |
| Radius | 0~15mm |
| Max dia. of cutter | 300mm |
An accurate radius on the corner of teeth can be ground.
4. Cylindrical Grinding Attachment
This attachment is most suitable for straight or taper cylindrical grinding and for face grinding of various tools.
| Capacity | |
| Swing | 10″ (250mm) |
| Main spindle speed | 370rpm |
| Motor 1/4 HP (0.2kw) | |
5. Helical Grinding Attachment
This attachment is suitable for grinding the relief and rake angle of spiral cutters or the straight teeth of hobs, end mills and center drills. The work spindle is possible to be turned twice at Max. for the lead of 0 through infinity.
| Taper hole of work spindle | MT No. 4. |
| Lead | 0-8 (stepless) |
| Spindle turns twice at max.index | 24 (standard) |
| Grinding length | max. 12.5″ (320mm), when helix angle is 0° |
| Module (Hob) | Max. 8 |
| Helix (Hob) | Max. ±8° |
6. Internal Grinding Attachment
This is generally used with the Cylindrical Grinding Attachment. Of coure, it can also be used for grinding internal tapers.
| Capacity | |

7. Workhead Indexing Attachment
Accurate indexing can be made quickly and easily by mounting the Indexing Attachment on the standard workhead. This eliminates the need for a tooth rest which is normally required for grinding cutters. If not specified, workhead indexing attachment is provided with a plate of 24 equally spaced slots. Includes 24-notched index plate, other index plates... please specify number of notches required.
8. Extended Grinding Wheel Spindle
This attachment comes in handy when the longer reach of an extended spindle is required. The spindle is a cartridge spindle that is readily interchangeable with standard spindle. Spindle extension is 3″ (75mm).
9. Surface Grinding Attachment
This attachment is also called "Universal Vise" and ideally suited for grinding bits as well as surface grinding. It consists of swivel vise and base. The intermediate support permits the vise to swivel 360 degrees horizontaly and vertically.

11. Lathe & Planer Tool Grinding Attachment
This attachment facilitates setting cutters for grinding rake and relief angles. The large work support provides an outstanding grinding capability. This attachment is ideally suited for grinding cutters for lathes and planers.
| Capacity | 3/8″ ~ 1 1/2″ (10 ~ 38mm) |
Convenient for grinding rake face and relief angles.
12. Spring Collet Chuck
This chuck can be mounted directly in the taper hole of the workhead (ASA No. 50). This is an indispensable attachment for small cutter grinding. Spring Collet Chuck for larger size cutters or adapter for 5C collets are also available.

13. Wet Grinding Attachment
This is a coolant supply system used for cylindrical, internal, surface grinding and various cutter grinding operations.
| Coolant pump motor | 1/8 HP (0.1kw) |
14. Dust Collector
The dust collector protects operator safety and health by collecting dust particles flying off the grinding wheel during grinding operations. The compact size of the dust collector requires a minimum of floor space.
