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 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 [...]
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, [...]
Oil & Gas Industry Parts China 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 [...]
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 Oil & Gas Industry Parts China, we [...]
Some Oil & Gas Industry Parts China 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 [...]
“For machine shops like Oil & Gas Industry Parts China, 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 Oil & Gas Industry Parts China. “Customer prints or purchase orders will state if this [...]
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 [...]
Approximately 30% of the components that Oil & Gas Industry Parts China 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. [...]
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 [...]
