John Prosock Machine, Inc. produces
precision threads with accurate location using
advanced CNC milling centers. By utilizing CNC
technology, we have the ability to consistently
achieve the same start point for the thread, so
that connection tees fit into the threaded holes
at the same location every time. Thread milling
provides John Prosock Machine complete control
over the quality of the threads with a reliable,
high-speed performance, precision machining process.
Computer Numerical Control (CNC)
machines function through automation programmed
by software, such as macros, to reduce setup time,
create clean cuts, enhance the precision of the
process, and eliminate errors that can result
from manual calculations. John Prosock’s
expert machinists are skilled in the latest software
for CNC milling machinery. In minutes they can
enter the type of thread, diameter, depth, and
group of work materials to be cut. Once programmed,
the software automatically generates the machine
code, recommends the best cutter for the job,
and selects the optimum cutting parameters. In
just one operation John Prosock Machine’s
thread milling forms both the hole and the thread,
which streamlines the process to meet quality
requirements and customers’ deadlines.
- Threads can be placed closer
to the bottom of a blind hole
- Leaves room for chips to fall
away
- Left- or right-handed threads
can be programmed
- High cutting speeds and feed
rates for efficient cycle times
- A single tool can give the same
pitch to a range of hole diameters
Maximum flexibility with a small
inventory of tools. A variety of holes can be
machined and a wide range of pitches can be fabricated
by simply programming the milling machine to run
at a specific cutting diameter. John Prosock Machine
offers a wide variety of hole-making operations.
Tools can drill the hole, chamfer the hole, machine
the thread, and cut away the incomplete portion
at the bottom.
Tapping
vs. Thread Milling
The two means of making a threaded hole are tapping
and thread milling. Tapping is an older technique,
and has primarily been used to make threads in
small holes. However, as technology improves it
is possible to threadmill smaller and smaller
holes. When compared to tapping, thread milling
produces far superior threads.
Since 1982, John Prosock Machine,
Inc. has been providing customers with high quality
parts for a wide range of industrial applications
on or before deadlines. We are constantly searching
for new ways to improve the precision of both
our process and the parts we machine. To maintain
our position as a leading machining company we
have invested in state-of-the-art CNC milling
machines capable of tight tolerance thread milling.
