precision machining - National Technologies, Inc.

Value
In the custom components industry, National Technologies' capabilities are second to none. Our management and supervisory team have logged over 225 years of hands-on experience. The result? Better engineering. Better quality. Better value.

Precision machining options. Given our breadth of experience and the great variety of the machines on our floor, we have the capacity to produce parts in many ways. Working with you, we choose the best process to meet your needs.

Vendor-certified work. Our work has been certified by some of the worlds largest OEMs, a distinction that sets us apart. We have sustained these certifications for many years - even as their requirements have become progressively more stringent.

Precision Machining - THE RESULT OF PRE-PRODUCTION PLANNING

Your order begins at a pre-production engineering meeting. Nothing at National Technologies is done "on the fly." Our engineers review your prints and decide upon the most efficient process for production.

Next, our engineering department issues process documents that highlight details important to each machinist. These drawings clarify specifications, secure conversions, and highlight critical dimensions. This extra step eliminates any potential for operator error as the part moves through production.

Plus, our pre-engineering protects the integrity of each part's critical dimensions in a second way - by anticipating distortions and preventing them. Processes, such as heat treating or plating, may affect material sizes. To offset a variance, like expansion, our process documents may tighten parameters on a first operation to allow for variances on a second. Our planning assures that your finished part or assembly conforms exactly to print specifications.

We can promise such precision machining because we are knowledgeable professionals with years of experience in the art of machining.

Quality - UPHELD BY RIGOROUS INTERNAL DISCIPLINES

We chart all critical features throughout the manufacturing process using our statistical process control program. Our disciplined approach guarantees a consistently good product.

For each machining sequence, operators complete a formal start-up report, ensuring that they understand their part of the process - and subsequent processing relevant to their operation. This report improves material flow and eliminates the potential for operator error.
Identification documents are attached to all lots ensuring complete traceability.
Each part is sampled by ASQ-certified inspectors. If the part doesn't pass our AQL criteria (C=0 1.0 AQL), it doesn't leave the dock. Period.

EFFICIENCY - FOR ON-TIME DELIVERIES

24-hour access to our own in-house tool room. Our tool room experts and our EDM capabilities eliminate downtime in replacing damaged or worn tooling. An uncommon asset among today's machining companies, our tool-making capacity gives us improved efficiency, floor control, and quality you can depend on.
State -of-the-art CNC machinery. Complementing our 100+ conventional machines, we have more than 30 state-of-the art CNC turning and Vertical Machining centers. 60% of these centers are less than 3 years old. We invest only in the best: super-precision equipment built to perform.
State-of-the-art conventional equipment with add-on tooling. We select our conventional machines with great care. All operate with add-on tooling enabling us to produce parts to closer tolerances than standard turning machines. Zero-datum insertable tooling, along with high-capacity cut-off saws and other specialized equipment, increases our productivity - often eliminating the need for secondary operations.
EDM for speed and accuracy. Our tool room's EDM technology provides tooling which reduces the in-cut time to a fraction of that spent using conventional methods. This expertise also improves the quality of the part.

VERSATILITY - THAT GIVES YOU OPTIONS
Simple parts or intricate. Tough jobs or easy. Traditional parts or custom machining. Small runs and large. In everything from tough steels to alloyed steels to brass, bronze, aluminum or plastic. We do it all. Everything from tough steels to alloy steels to brass, bronze, aluminum or plastic.

A WELL-TRAINED WORKFORCE - FOR EXPERTISE AT ALL STAGES OF THE OPERATION
To standardize the expertise of our machine operators, we require all newly hired machinists to attend classes in our Training Department. Instructors from local technical colleges teach these classes, and all employees must pass the final examinations.

We encourage our people to improve their skills:
Supervisors and leadmen are required to take advanced courses. We reimburse employees for any classes taken outside the company that will improve their performance. When employees are reviewed, their participation in outside education helps determine merit increases. By rewarding extra efforts, we encourage our people to take pride in their work.

STRONG TECHNICAL SUPPORT - TO EXPEDITE YOUR ORDER
