Frequently Asked Questions
What is CNC Machining?
CNC machining is the intersection of computer science, material science, and manufacturing engineering. CNC machines are computer controlled machines used to cut and shape plastics and metal (and wood and much more!). They can be used to machine highly complex individual parts, or large quantities of parts. CNC machines are fast and powerful, allowing parts to be manufactured in a cost effective way. They are also highly versatile, able to be configured to cut features such as grooves, holes, threads, pockets, shafts, and almost anything else you can think of. CNC machines run on a language called G-Code, which allows us to program the machines to cut shapes and features based on customer specifications.
What's Your Minimum Order Charge?
Our minimum charge is $70. Having a minimum means that we’re able to deliver consistent quality and attention to every order, no matter how small.
Do You Bend Metal?
Sometimes! We build stamping dies which can bend, and cut metal, and we run presses in house - but a custom die typically only makes sense for larger quantities of parts (500+). If you have a smaller quantity of simple, bent parts, we’d be happy to connect you with the correct professional to perform that service. Or, if you have a bent part that requires other machining or is part of an assembly of machined parts, we’d be happy to source a turnkey product for you.
Do You Weld?
Not typically. We weld some internal projects, but advanced welding is a wide and deep knowledge base which we prefer to leave to other professionals. If your welded part involves other machining, we’d be happy to work with our trusted vendors to provide a complete product solution for you.
What Sort of Files Can You Quote To?
PDF drawings with dimensions and tolerances are the easiest thing to work with. Universal CAD files such as DXF or STP can also be very useful. CAD package file types like DWG, SLDDRT, IPT, or SLDPRT can require translators to be read by everyone - conversion to universal file types is preferred. If a CAD file is provided without tolerances, we may assume certain tolerances, or ask for more clarification on intended functions.
How Do I Send Files?
Email is the best method to get files to us. You can send them to quotes@jacobsmachining.com, and we’ll review them ASAP. If you’re local, we also welcome visitors! This means you can bring samples for us to review, if applicable.
What is Wire EDM?
Wire EDM (electrical discharge machining) is a non-traditional machining process which uses electricity to precisely erode conductive materials. Cutting takes place with a small diameter (as small as .006”) brass wire, which allows for nearly sharp corner through features to be cut (.003” corner radius). Wire EDM does require all features to be through (no blind holes or pockets) because the wire is fed from the top and recaptured on the bottom. But because of the nature of the cutting action, extremely tight tolerances can be held and features which cannot be machined traditionally are possible. Additionally, high hardness materials such as carbide can be cut with wire EDM - the only requirement is that the material be electrically conductive. This means materials such as carbide or hardened tool steel can easily be cut with wire EDM.
What is "Design for Manufacturability"?
Certain physical parameters limit how something can be manufactured. These are things like material warpage, cutting tool shapes, material hardnesses, and cutting tool access. Generally speaking, almost anything can be manufactured, but not all things are cost effective. Design for manufacturability reviews can help to reduce the cost of a manufactured item by assessing these physical constraints relative to the needs of the part. Sometimes, something as simple as changing a hole size or pocket shape can drastically reduce parts costs. While we understand that the design of the part may not be able to be adjusted, when cost is a concern, we’re happy to provide suggestions to reduce manufacturing expenses.
What is G-Code?
G-Code is a nearly universal language that is used to program industrial machines. Everything from 3D printers to large industrial robots run on G-Code. We can either write this code manually, or use software called CAM software to generate the code for us. Your part design is evaluated from a process perspective, and then the appropriate code is produced to manufacture the part in our CNC machines.
