PPAP (Production Part Approval Process) for Precision Turned Parts

The Production Part Approval Process (PPAP) is a valuable tool for establishing confidence in a component supplier’s production processes. The PPAP process was initially specified in the automotive and aerospace industries. Today, it has been integrated into the requirements of some medical and industrial customers. At Pioneer Service, we [...]

FAI (First Article Inspection) Reports for Precision Machining

Some Pioneer Service customers will require a First Article Inspection Report with the shipment of their first order on a new part.  This report provides a detailed verification that all specified requirements on a customer print have been consistently met in production. Years ago, FAI reports were most likely [...]

RoHS Compliancy in a Precision Machine Shop

“For machine shops like Pioneer Service, RoHS compliancy is often required by customers for the bar stock used to machine the components, as well as some finishing services like anodizing, plating, etc.” Karina Ramanauskas, Buyer and Planner at Pioneer Service. “Customer prints or purchase orders will state if this [...]

The Most Common Types of Finishing Services for Precision Machined Components – Part 2

Part 2: Finishing Services that Remove or Reshape the Component Surface There are several surface finishing techniques that “remove or reshape the surface layer” of a precision machined component.  These finishing techniques can be applied to a wide variety of materials, and provide increased durability, tighter tolerances, better aesthetics [...]

The Most Common Types of Finishing Services for Precision Machined Components – Part 1

Part 1: Finishing Services that Add to or Alter the Component Surface There are a variety of surface finishing techniques that add to or alter the surface layer of metal for a precision turned component.  These finishing techniques can be utilized for aesthetic reasons, to protect the part from [...]

Honing and Lapping Precision Turned Components

Approximately 30% of the components that Pioneer Service manufactures for our clients require grinding after the machining process.  Standard grinding (both centerless and centered) produces a finer surface finish and/or more precise dimensions than can be achieved during the turning process on a CNC Swiss or CNC Turning Center. [...]

Turning Vs. Milling: What’s the Difference for Precision Machining?

We have run into this question with many of our clients.  They say something to the extent of, “Help me understand what is turning and what is milling, because to me it is all machining.”  CNC turning and milling are two types of precision machining, but exactly what is [...]

Centerless Grinding of Precision Machined Components

To modify the outside diameter (OD) of a precision machined component, there are two types of cylindrical surface grinding operations that can be used: centerless and centered.  Grinding the OD of a CNC Swiss turned component offers several benefits: a smoother surface finish (Ra), a tighter OD tolerance (up [...]

The 5 Most Common Types of Precision CNC Machining

CNC machining is a general term used for a variety of machining applications.  "CNC" stands for Computer Numerical Controlled and refers to the programmable feature of the machine, allowing the machine to perform many functions with minimal human control. CNC machining is the fabrication of a component using a [...]
