Swiss Turning and 5-Axis Machining in Stockton: GC Machining

Some parts are small, some are complex, and some are both. Buyers in Stockton who source components for aerospace, semiconductor and other demanding fields often use terms that sound technical but have simple meanings. GC Machining, Inc. is listed here for CNC milling, CNC turning, 5-axis machining, Swiss machining, assembly and plastics machining, along with quality tags such as AS9100 and ITAR. This page explains those terms in plain language.

What Swiss turning is

A Swiss-type lathe holds a bar close to the cutting tool and feeds it forward as it is machined. Because the cut happens near the support, long and slender parts stay steady. Swiss machines are used for small screws, pins, shafts and medical or electronic components. If your part is small and round with fine features, ask whether Swiss turning suits it.

What 5-axis machining is

A standard mill moves a tool in three directions. A 5-axis machine adds two rotations, so the tool can approach a part from many angles in one setup. That helps with complex shapes and can reduce the number of times a part is moved and re-measured. Five-axis work is common in aerospace brackets, housings and impellers.

Horizontal machining

Horizontal mills turn the spindle sideways, which lets chips fall away from the cut and allows parts to be mounted on towers or pallets. They are often used for production. If you expect a large volume, it is worth asking how it will be set up.

What AS9100 and ITAR mean

AS9100 is a quality management standard used in the aerospace industry. A shop that lists it has a system for controlling documents, processes and records. ITAR is a United States regulation that controls certain defense related information and products. Buyers whose parts fall under it need to deal with shops that handle that restriction correctly. If your work is covered, say so at the start of your request.

Prototype through production

Many programs begin with a few prototype parts and later grow. A shop that can handle both can keep the same setup knowledge as the volume rises. Tell the shop what volume you expect so it can quote accordingly.

What to include with a request

• Drawing and 3D model
• Material and any certification paperwork you need
• Quantity and delivery schedule
• Any quality system requirement from your own customer
• Whether the part is subject to export rules

Plastics and assembly

Plastic parts and small assemblies often appear in semiconductor and instrument work. If your order includes assembly, list the purchased components and who supplies them.

A note on questions

Specialized work generates more questions than ordinary parts, and that is normal. A short list of what you know, what you need and what you are unsure about is the best way to start. Buyers in Stockton and elsewhere are welcome to ask general questions through the quote form.
