 General
Q.Will you manufacture a
prototype lot or do you just do
large quantity production?
A.We will manufacture one piece or a million.
We prefer to work
with designers from the initial
concept through production and
frequently manufacture lots
from one to five pieces.
Q.How tight a tolerance
can you hold on a production basis?
A.This is very dependent on part geometry, material,
heat
treatment and plating (when
required). This question can
be best answered after a review
of the part drawings.
Q.Do you do assembly work?
A.Yes, very frequently. (Mechanical only, not
electrical)
Q.Do you enter into ship-to-stock
relationships?
A.Yes. After establishing a good track record
with a
customer we frequently enter
into this type of agreement.
Q.What is the largest part
you can handle? The smallest?
A.We can turn and grind up to a 10" (250mm) diameter.
We can handle a 24" x 36" (600mm
x 900mm) cube in
milling but weight and geometry
of the part are important
considerations. We have machined
parts under .040" (1mm)
in diameter to very tight tolerances.
Q.Do you machine carbide?
Ceramics?
A.Sorry. No to both.
Q.May we visit your facility
for a quality audit?
A.Please do. We welcome audits.
Q.What is the maximum capacity
of your Swiss type lathes?
A.20mm (.787") diameter.
Q.What is your typical lead
time?
A.This depends on the complexity of the part,
outside operations
such as heat treatment or plating,
and material availability.
Q.Will you submit a first
piece for approval prior to beginning production?
A.Yes, but depending on the complexity of the
part there may
be a charge.
Q.In what format can you
accept e-mail drawings?
A.DXF, DWG, IGES, PDF and WMF
Medical
Components
Q.Do you machine the implantable
grades of titanium and
stainless steel?
A.On a regular basis. Our secured material control
area has
been FDA approved.
Q.Can you offer design assistance
on medical devices?
A.We can only contribute to the design of a component
as it
relates to the manufacturing
techniques or the economy of
manufacturing. Insurance liabilities
do not allow us to give
pure design assistance.
Aerospace
Components
Q.Do you do high speed machining?
A.Our facilities (see facilities
list) allow us to do high speed
machining when the material
and the geometry are suitable.
Q.Do you machine some of
the more exotic aerospace alloys?
Titanium alloys?
A.Over the many years LaVezzi has been manufacturing
precision components, we have
machined almost every
alloy. LaVezzi annually spends
more on titanium stock than
all other alloys combined.
Sprockets
Q.I require some design
assistance on a sprocket drive.
Where do I start?
A.See our 'Design
Assistance Form.'
Q.I know exactly what I
need regarding a sprocket but I
am unsure
of the tooth form. Can you help me?
A.No problem. Send us what you have and upon receipt
of
your order, you will be advised of the proper tooth form.
Q.Do you make chain or timing
belt type sprockets?
A.Sorry, no. We can, but you can purchase these
much more
economically through a stocking
supplier.
TRU-POS™
Locators
Q.Why use a locator to determine
the location of a threaded
hole? Our current method is
cheaper and just fine.
A.Inspection methods must ensure that your parts
meet or
exceed specification. Checking
the hole location with a
gage pin, a steel ball, a screw
with a machined head, or
a probe tip is inaccurate since
the pitch diameter is not
referenced as specified in ASME
Y14.5M-1994.
Q.If my threaded hole is
oversize will the TRU-POS™ function
properly?
A.Yes! When the locator is seated, the upward
force exerted
against the thread flanks causes
the locator to position itself
on the centerline of the tapped
hole.
Q.Are TRU-POS™ locators
difficult to use?
A.No! TRU-POS™ locators are ground .0001"
under your go
gauge size for easy finger tight
insertion, thereby improving
productivity while eliminating
sore fingers. The knurled
surface is placed at the top
of the locator which makes it
easier to grip. TRU-POS™
is ground to the base of the locator
providing a more accurate measurement
of the tapped hole,
since the CMM probe will be
closer to the surface.
Q Why aren't your locators
split, like other designs?
A.Material fatigue, excessive installation force,
etc., play a
vital role in the repeatability
of locating gages. TRU-POS™
were designed to provide a reliable
method in which
repeatability is constant.
Q.Are special sizes or configurations
available?
A.Yes! Special sizes and configurations can be
manufactured
to meet your unique requirements.
Please call or e-mail your
specifications for a quote.
Q.Are certifications of
compliance or calibration available?
A.Yes. Please specify at time of order. TRU-POS™
locators can
also be recalibrated for a nominal
service charge.
Q.We already use locators.Why
switch to TRU-POS™?
A. Extensive availability of sizes
*Unified *Metric *Heli-Coli
*Pipe Thread *Tapered
Immediate Delivery
Special Configurations Available
Reliability
Repeatability
Improved Productivity
Better Accuracy
Q.Do
you make TRU-POS™
Locators for external threads?
A.Yes,
by special order, but please be advised that cost and
delivery
may be prohibitive.
Q.How much oversize can
the pitch diameter be?
A.It
really depends on the courseness of the thread and can
only be answered on a case by
case basis.
Q.How
repeatable are your locators?
A.Tests
at LaVezzi and a third party testing lab have proven
that
the straight locators are repeatable
within .0001" and
the
tapered locators are repeatable within .0002".
