Lathe Milling Attachment is a mechanical device installed on aa 4.5 feet Lathe through which any numbers of flats can be done on the OD of the component right from 2 to 12 numbers cut in one stroke without any indexing (either straight or in tapered fashion). Also slots on face can be cut. This attachment can be mounted on any general purpose centre lathe of 4.5 feet bed length without any geometrical change in origin of lathe.
In general when we do milling the job is fixed and tool rotates and we index the job for multiple flats. On lathe job rotates and tool is fixed while round turning. This attachment is a combination of lathe and milling machine by which many advantages can be achieved.
Making even number of flats:
If we mount one cartridge on the pocket provided on cutter it will strike the job twice in one rotation as such one tool will make two flats in one stroke without indexing. The size of A/F can be achieved by giving a desired dept of cut by moving cross slide just like lathe. Length of flat can be done by using auto feed or manually of longitudinal travel.
Similarly if we mount two tools then directly a square will be cut in one stroke.
For Hex – mount three tools.
For octagon- mount four tools.
Like this up to 12 nos. of flats can be cut in one stroke without indexing.
Slots on Face:
To make slot on face special groove tool is used which can be mounted on face of cutter.
In this case job is brought at the centre of the face of slot tool and plunge for depth of slot. If we put one tool it will be one straight slot on face. Like that two or three slots can be made at a time.
Uneven number of flats:
Uneven number of flat like one flat, triangle (3), Pentagon (5), heptagon (7) is cut in one stroke without indexing.

These attachments are supplied as per requirement. We provide this with Collet chuck as well.
