Q: What is the difference between CNC turning and milling?

Both are types of machining. Turning refers to machining bar or tube stock (referred to as the “work piece”) with static tooling as it rotates while it is clamped by a collet. Milling refers to machining done to a static work piece with tooling that is moving or “live”. We refer to “turned parts” to include those that are turned with or with milled features. Our CNC (Computer Numerical Controlled) machines perform both turning and milling operations. This capability mitigates the need for costly secondary machining operations, and also allows parts to have features that need to be timed, or registered, to one another. Click to see several examples of turned parts we make.

Q: What is the difference between a lathe, a screw machine, a turning center, and a Swiss lathe?

In its simplest form, a lathe is a machine that makes turned parts from bar stock, but without any milling capability. Screw machines, turning centers, and Swiss lathes are lathes that have the ability to turn and mill parts. Turning centers and Swiss lathes can typically make more complicated parts, and hold tighter tolerances, than screw machines. And Swiss lathes can machine smaller parts and thinner, longer parts than other types of lathes. Pioneer Service has all three turning machine platforms to accommodate a broad spectrum of part designs.

Q: What type of parts does Pioneer Service make? What services do you offer?

Pioneer Service manufactures custom metal and plastic parts from bar or tube stock. The machining we perform includes turning and/or milling. In addition to machining, we also offer two types of centerless OD grinding. See the list of examples of part descriptions we manufacture.

Q: What industries do you serve?

Our customers range from OEMs to Product Development firms to Distributors to Contract Assemblers and are involved with almost every industry imaginable. A few of them are mentioned here.

Q: What type of inspection equipment do you have?

In addition to standard equipment, including optical comparators, plug gages, ring gages, and thread gages, we also two types of automated Visual Inspection Systems. The Oasis Vision System allows us to very quickly check parts and determine if dimensions are in spec or not with red/green/yellow indicators. Our Micro-Vu Vertex Measuring Center allows us to upload CAD files of parts so that we can measure either one or several pieces of a given part at a time, allowing us to transfer measurement readings into SPC reporting format. This allows our Quality Inspectors to verify First Article and in-process inspections as quickly as possible. Visit our Quality page for more information.

Q: Where are your customers located?

We have been serving our customers located throughout North America for over 25 years. We ship our customers’ product via any mode they want, including FedEx, UPS, and common carrier.

Q: What is the smallest quantity you make? What is the largest quantity you make?

We make parts in quantities ranging from 1 piece to over 1 million pieces per year, and everything in between. In other words, no quantity is too small or too large for us. We enjoy a mix of proof-of-concept, prototype and production parts, so you should consider us for any size job.

Q: What is the smallest part you can make? What is the largest part you can make?

The simplest answer to both questions is that it depends on several factors. In general, though, we are able to machine parts with minor ODs as small as 2mm (.080”) and major ODs as large as 200mm (8”). Rather than guess, though, we highly recommend that you contact our technical sales staff to review your part needs as early in the design cycle as possible.

Q: What information do you need to quote my part?

We understand that in many cases you may not have all the information at hand to quote a part. At a minimum, though, we would appreciate receiving:
• A fully dimensioned print, drawing, sketch (preferably in a pdf format) and/or CAD file (we work with SolidWorks.)
• The raw material(s) specified
• Any necessary secondary operations, including heat treating, plating or finishing specifications
• Any customer specifications that may apply; such as 1st Article Inspection, PPAP requirements, material and outside process certificates required
• The quantities you want us to quote
• Any other background information that would be helpful, including target pricing or lead-times required.

Q: Can you help me engineer my part?

Designing parts is technically outside the scope of our ISO registration as a contract manufacturer, but we offer and encourage our customers to rely on us for part Design for Manufacturability (DFM). Simply put, you understand the design intent of your part.

Q: How quickly can I expect to receive your quote for my part?

We understand that the proverbial “early bird gets the worm”, and so we work to be the first to provide you a quotation. In order to serve you best, let us know when you need to receive our quotation and provide your contact information in case we have any questions or recommendations.

Q: What is your standard delivery lead-time for prototype parts? For production parts?

There is no such thing as a “standard delivery lead-time” since every part number is inherently unique, but our Sales Team is available to quickly review your part to estimate how quickly we can machine and deliver it. Request a Quote
