Problem

Electrical terminals, sanitary fittings and connector parts are made in large volumes on sliding-head (Swiss-type) and automatic lathes. Space around the part is limited, cycle times are short, and the knurl must be identical on every part for assembly and appearance.

Solution

Compact holders matched to the machine's tool block keep knurling inside the normal cycle.

Cut knurling holders with an adjustable head are the usual choice for brass: low force, little diameter growth, clean chips.
Form knurling holders suit steel parts and press-fit knurls.
Straddle holders support thin parts from both sides; special holders are made for non-standard tool positions.
