The
advent of modern machining centers allows for simultaneous
multi-axis machining. This permits thread milling operations
to be completed easily with the use of helical interpolation
programming and economically with modern tools and methods.
The
Stellram® system includes solid carbide tools for threads
from M6 or 1/4" UNC and the world patented indexable insert
system with single insert, twin insert and four inserted tools
for ultimate flexibility.
The
Stellram thread milling system is 100% full thread form on
inserts and solid carbide tools.
They
produce a thread to within 1 pitch of the bottom of blind
or counterbored holes. No undercuts are required, therefore
no pre-work and fewer tools required. Thread mills produce
a thread to any size or tolerance in a predictable and consistent
manner. Right hand or left hand threads can be produced with
the same tool.
Stellram's
thread mills complete a thread in one machine set up. Tools
with NPT, NPTF, BSPT, BSW thread forms produce internal, external,
right hand and left hand threads with the same tools. They
produce easy to handle chips, minimize power requirements
and interrupted cuts and casting mis-match is no problem.
Excellent surface finish eliminates deburring operations.
Multi-start threads are easy to produce and there are no
broken taps to remove.
