Computer numeric control. This is a manufacturing technique using large automated equipment to form components to print.
Yes, INTA has very sophisticated equipment including a 7-axis Ganesh with auto-feeder. Other equipment includes Haas horizontal CNC centers, an Okuma vertical lathe and much, much more. INTA does not offer in-house EDM or welding instead outsourcing those operations along with black oxide and some other types of finishes including anodize. INTA also makes simple parts for low prices. Most of our work is custom and we will need engineering drawings to manufacture the necessary component or assembly. INTA Machining works with INTA Technologies to offer turn-key solutions and one-stop-shopping for customer seeking brazed assemblies, kits, plated parts and more.
INTA uses only high quality materials and believes in fair pay and benefits for employees but due to the long history, supplier agreements, high level of automation, superior management and planning, INTA is able to be very competitive and offer low priced solutions for many customers. INTA does specialize in high-end machining but also offers high volume, low priced runs.

On type of sustainable or environmentally friendly cutting fluid is the type based on vegetable oil. Cut-Max V500 from Houghton International is a popular brand.
Yes, some types of green cutting fluids have lower flash points than mineral oils which means that the need for costly CO2 fire blanket equipment may be reduced. Lower viscosity translates into extended tool life.
No, mineral oils or chlorinated additives are not contained most green cutting fluids.
Green cutting fluids help companies comply with environmental guidelines. Some vegetable oils maintain fluid longer and reduce dragout on swarf. Green cutting fluids can be more expensive. Also see the previous three questions.

ASME B5.54 is a machine tool body diagonal displacement measurement standard.
Similar to ASME B5.54, ISO 230-6 is also a common machine tool body diagonal displacement measurement standard.
Many kinds of components are manufactured by INTA Machining. Most of the items are custom made-to-order items. Many of the items are used in industries such as semiconductor processing, manufacturing, chemical treatment, aerospace, optics, lasers and more. We specialize in CuW, copper, aluminum and stainless steel.
Yes, INTA commonly makes custom-order parts.
Yes, prototype to production and anything in between.
Yes, INTA Machining manufactures plastic components but does not offer any type of injection molding in-house.
Yes, INTA welcomes large production orders.
INTA Machining is not currently NADCAP certified but plans to achieve the milestone in the future.
Yes, ISO 9001:2008 certified. NSAI is our registrar.
Yes, INTA Machining uses tools such as CMMs to inspect critical dimensions.
Yes.
Proper engineering of the three main features of the cutting tool provide force for the cutting edge and also allows chips and coolant to flow easily away from the work area. The three main angles are: Rake, approach or lead and clearance.
Pitch, or pitch of a thread, is the distance between threads. In the English system, the pitch is the reciprocal of the threads per inch.
UN Minor diameter = UN Major diameter 2 x 0.65 x pitch
The formula is valid for UN threads only. See below and/or contact INTA for information on other thread types contact@intatech.com
IOS are metric threads.
UN threads have the following features:
Angle of thread = 60 degrees (same as IOS)
Spacing between threads = pitch/8
Minor diameter = Major diameter - 2 x .65 x pitch
Acme threads have these features:
Angle of thread = 29 degrees
Spacing between threads = pitch/2
Minor diameter = Major diameter - 2 x pitch/2
Unified National.
Rounded crests.
Spacing between threads = pitch/2
Minor diameter = Major diameter - 2 x pitch/2
Thread angle = zero degrees
Spacing between threads = pitch/2
Minor diameter = Major diameter - 2 x pitch/2
Cut with a square profile
This type of thread has a stronger shoulder and is much more robust than a v-form thread.
Square threads are more expensive and more difficult to manufacture.
After the size (nominal in fraction form), a dash and TPI, next the designer identifies the series. Some common choices include:
UN
Acme
ISO
Square
Knuckle
Whitworth
Pipe
Trapezoidal
Buttress
Threads per inch.
Some common options are listed below:
UN
Acme
ISO
Square
Knuckle
Whitworth
Pipe
Trapezoidal
Buttress
See previous answer. The options contained in the list are offered by INTA.
C coarse thread
F fine thread
EF extra-fine thread
For ANSI (English) threads, after indicating the following:
General identification of fastener
Type of head
Classification of fastener
Nominal size in fractions
TPI
Series
Type of thread
Class of fit
Use the letter A after class of fit designation (1, 2 or 3 loose, average or tight) to indicate external threads.
For metric (ISO) threads, after indicating the following:
General identification of fastener and type of head or nut
Letter M metric designation
Diameter (mm)
Thread pitch (mm)
Length (mm)
Use only one of the following:
4g tight fit (external)
6g medium fit (external)
8g free fit (external)
For assistance, contact Blake Kneedler at INTA 408-748-9955 x113
See the previous answer for metric applications. For ANSI applications, follow the instructions in the previous answer and then place any qualifiers (optional) after the A for LH (left hand threads) or double (for double threads). Finally, the length goes last, measured in inches.
Here are two examples:
Screw round hd
M20 x 3.0 4g x 80
Screw hex hd machine
1/8 24 UNF 2A .20
The first example describes an 80mm long screw. The second example is for a 0.20 inch long screw.
See previous answer.
See How do I specify the length of screw or bolt on a drawing?
For ANSI (English) threads, after indicating the following:
General identification of fastener
Type of head
Classification of fastener
Nominal size in fractions
TPI
Series
Type of thread
Class of fit
Use the letter B after class of fit designation (1, 2 or 3 loose, average or tight) to indicate internal threads.
For metric (ISO) threads, after indicating the following:
General identification of fastener and type of head or nut
Letter M metric designation
Diameter (mm)
Thread pitch (mm)
Use only one of the following:
5H tight fit (internal)
6H medium fit (internal)
7H free fit (internal)
For assistance, contact Blake Kneedler at INTA 408-748-9955 x113
Four threads are added on.
For ANSI applications, use the same procedure shown in How does a designer specify internal threads? then add a depth symbol (omit for thru holes) and the depth in inches.
The lead is the distance needed to advance in one revolution. For normal threads, the lead is equal to the pitch. For double threads the lead is 2 x pitch. For triple threads, the lead = 3 x pitch.
The length is measured differently depending on the type of screw. If the screw has an angled head or a flat head designed to be countersunk then the length is measured from the top of the angled area to the bottom tip of the screw. Hex and round screws that are designed to have their heads extend above the material are measured from the bottom of the head. If counterbored, the height of the screw head is included in the specified length.
For metric (ISO) threads, indicate the following:
General identification of thread
Letter M metric designation
Diameter (mm)
Thread pitch (mm)
Length of thread (mm)
Use one of the following:
4g tight fit (external)
6g medium fit (external)
8g free fit (external)
5H tight fit (internal)
6H medium fit (internal)
7H free fit (internal)
See previous answer. __g and __H are the thread tolerances.
55 degrees.
