In many different industries from parts and components for firearms to robotics and medical devices, precision is critical. Not only is precision important for the functioning of the device or system, but it is also required for safety, long life cycles and perhaps even for life-saving technology.
The best companies that specialize in precision machined parts understand the importance of quality control the production of the final component. They see this as not just a certificate or an ideal that represents the company publically, but rather as the central and driving force throughout the production process.
Training and Certification
When the company is focused on manufacturing precision machined parts, there is a focus on training of the staff in quality control. Most of these top companies will move forward with ISO 9001 certification, which is specific to developing a company-wide approach to quality.
Additionally, companies producing medical devices and orthopedic or dental implants will also have ISO 13485 certification, which is specific to medical device production. A few companies may also have additional certification, including AS9001C. This is granted by the NSF-ISR and applies specifically to the production of aviation, space and defense quality management system certification.
Bottom Up Quality Control
A unique approach to quality control offered by the best companies manufacturing precision machined parts is the bottom-up, company-wide quality control system. This means that everyone in the company is focused on quality control and is aware of the appropriate inspections and requirements that are in place.
This allows each employee to be responsible for quality management, rather than depending on line managers or final product inspection to detect a problem. With this continual observation by employees combined with CNC equipment and continual data collection, the process is maintained to the quality standards set by the company.
Precision machined parts can be costly, but it doesn’t have to be, if you think outside the box. Taking the time to make clear drawings and design templates for the manufacturing company you choose to do the machine work for, can make all the difference. Additionally, choosing a manufacturing company that has extensive experience in the creation and assembly of precision machined parts will definitely help stay within your company’s budget.
Moreover, if you are not completely sure as to the kind of precision machined parts your project needs, speaking with experienced designers, machinists or knowledge management team members, like the ones at Aztalan Engineering, Inc., can help guide you to the right direction.
Drawing and Design
When designing a precision machined part, there are some elements you should consider. For example, creating shapes that are simple and small or that don’t waste material can help keep the overall project cost down. Think about the following factors:
- Eliminate the need for sharp inside and outside corners, or if you cannot eliminate them, increase the radius of inside and outside corners.
- For 3D parts, reduce the number of different hole diameters, or instead of using 3D parts, use 2D parts made from sheet material, which you can bolt or bend together to make 3D shapes.
- Avoid fine details in shapes such as long protrusions, thin shapes, shapes with lots of material removed, etc.
- Avoid the need for complex work-holding, as shapes with complex outer shapes are the most time consuming to setup for holding.
Precision Machined Parts Materials
There are several other ways to reduce the cost of your parts, including checking the pricing on different materials. For instance, it may help your company’s bottom-line to know that at times, harder materials tend be more expensive to use in manufacturing. Therefore, if you use a softer material such as aluminum, you can reduce the cost of the final product significantly.
Make sure to talk about your options with one of Aztalan Engineering’s experts during your design phase in order to work with the most cost-effective solutions for your product, rather than going back and trying to change everything later.
At Aztalan Engineering, we have been making high quality precision machined parts for more than thirty years, and our business continues to grow. Why? To put it simply, it’s because precision machining is the absolute best method in which to get top of the line products affordably and quickly. A wide range of industries trusts our machining services, including the medical, aerospace, defense, and energy markets. Keep reading to learn about some of the reasons why precision machined parts are the best way to go.
The best feature of parts made via precision machining is undoubtedly that they are typically error-free. First of all, machine production will always be more accurate than human production. More importantly, however, most CNC machines contain some sort of internal quality assurance detectors. The minute an error is detected during the manufacturing process, the machine will shut off to prevent making further mistakes. This saves you money on material that could have been wasted on unsatisfactory parts, as well as precious time.
Precision machined parts can be produced much faster than those by even the most skilled worker. The machines not only move faster, but also do so by simplifying the process and do in one step what workers would have to do in multiple steps. Since workers aren’t involved in the process, the whole timeline speeds up, since machines are able to work around the clock. With CNC machining, you’ll get your product in your hand as quickly as possible.
Precision and Less Waste
At Aztalan Engineering, our precise manufacturing method ensures that waste production is decreased, which means less ruined material headed to the dumpster. More so, with such a streamlined process, every last piece of material is utilized, meaning that no scraps go to waste.
A lot of CNC machines come with built in assembly features, meaning that we take care of another step for you! Without manual assembly, the time between when you place your order and when you receive your finished product are significantly reduced. You’ll be able to tackle larger, harder projects now!
