Heat Treatment of Precision Turned Parts

Heat treating a precision machined component is a controlled heating and cooling process that alters the physical properties of the metal to achieve a specific requirement.  In many cases, heat treatment is used to increase strength, hardness, and wear resistance. However, depending on the material and process involved, it [...]

NADCAP Certification and How It Applies to the Precision Machining Industry

NADCAP is an acronym for the National Aerospace and Defense Contractors Accreditation Program.  This accreditation is focused on setting quality standards for special processes like plating, heat treating and coatings.  This accreditation is intended for organizations doing business in the aerospace industry, where there is an extreme focus on [...]

Classes of Steel Commonly Used in Precision Machining

Steel is one of the most commonly used materials in CNC Swiss machining and CNC turning.  The main element of steel is iron (coming from iron ore) which is mined in over 50 countries around the world.  Currently most the world’s iron ore (over 75%) comes from Australia, Brazil, [...]

Measuring Surface Finishes on Precision Machined CNC Swiss Turned Components

Pioneer Service produces turned metal components to meet a wide variety of surface finish requirements.  Some finishes are available “off the machine” and others will require additional finishing processes. The part geometry and the chosen material will affect the surface finish that may be attained during machining on a [...]

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 [...]

Foreign Object Debris (FOD) Prevention in a Precision Machine Shop

Maintaining a clean production facility has many safety and health advantages. But for manufacturing, it can have a significant impact on the reduction of production delays, product quality and even damage to a company’s reputation. A precision machining company that implements a foreign object debris (FOD) prevention program has [...]

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 [...]
