Full-Service CNC Machining, Swiss Turning and Wire EDM in San Jose at Cpk Manufacturing

Some buyers want a supplier that can handle many types of work, so they do not need to switch shops each time a design changes. Cpk Manufacturing, Inc. is a full-service San Jose CNC machine shop listed here as founded in 1997, doing precision machining from prototype to ongoing production, with precision CNC machining, prototype, production, engineering, 5-axis milling, Swiss turning and wire EDM, in aluminum and plastics. The listing shows ISO 9001:2015, as stated on the site. This page explains what full service means and how to prepare a request for CNC machining in San Jose.

What full service can include

Full service usually means one shop can do several processes. On this listing that includes 5-axis milling, Swiss turning and wire EDM, with engineering support. Each process fits a different type of part.

5-axis milling

Five-axis milling reaches many faces of a part in one setup, which suits complex shapes and angled features. It helps keep related features aligned.

Swiss turning

Swiss turning is made for small, long and slender round parts. A guide bushing supports the bar close to the tool, so the part does not flex while it is cut. Common examples are pins, small shafts and connector parts.

Wire EDM

Wire EDM uses a thin wire and electrical sparks to cut conductive metals. It is useful for sharp inside corners, narrow slots and delicate shapes, since the wire does not push on the work like a cutter does. It is a good choice for shapes that are hard to mill.

Engineering

The listing names engineering. This can mean help with design for manufacturing, process planning or advice on how to make a part more economical. When you ask for a quote, ask for comments on anything that looks costly. Small design changes can save real money.

Prototype to production

The listing says the shop handles precision machining from prototype to ongoing production. That is useful when a design is expected to grow. Prototype quantities show whether the design works. Production quantities are tuned for a steady price and repeatable quality.

Materials

The listing names aluminum and plastics. Aluminum is light, cuts quickly and suits many housings and brackets. Plastics are used for weight, insulation and chemical resistance. If you need another material, say so in your request and ask whether it can be arranged.

What Cpk means

The shop’s name echoes a term used in quality work. Cpk is a statistic that shows how well a process fits within tolerance limits. If it matters to your program, ask how the shop tracks process capability on critical dimensions. A shop that can show data on repeat runs gives you more confidence.

How to describe a mixed job

• Which features need 5-axis milling
• Which are turned, and the bar diameter
• Which shapes need wire EDM, and the plate thickness
• Where features must be related to each other
• What is allowed to change if the shop suggests a better route

What to include in an RFQ

• Drawing and model with revision
• Material and grade
• Quantity and reorder plans
• Critical tolerances
• Finish
• Inspection and document needs
• Delivery date

A shop founded in 1997

The listing says the shop was founded in 1997. That is a long enough period for a business to learn from many projects, though a sample or first order tells you more.
