5. Shaping of T-slots

T-slots are machined according to the following working steps:

- recessing of a rectangular groove
- cutting of a horizontal recess
- cutting of the opposite horizontal recess


Figure 19. Working steps when machining a T-slot

(1) recessing of a rectangular groove, (2) cutting of a horizontal recess, (3) cutting of the opposite horizontal recess, 1 feeding movement

· Work with the machine vice.

· Make sure that the workpiece is accurately aligned.

· When using supports, apply only strips which are parallel ground.

· Recess the rectangular groove to the depth of the T-slot to be produced and finish-machine the upper width.

· Premachine wide slots.

· Premachine and finish the horizontal recesses with a T-slot cutting tool.

| Special attention during work is necessary, as the cutting operation can be watched only partially.

What is to be understood by the term “slot width”?
