“It’s going to be up and down, and you just got to be somewhat prepared for that and not get too exposed,” VP of business development, Jay Mallinckrodt said in an interview.
China Machined Parts was quoted in the Wall Street Journal regarding trends in the Fracking market.
In a typical production machining operations the quality focus is generally on the process and procedures that occur while parts are being produced. But, the quality management system doesn’t end there. Ultimately the shipping department is the final line of defense in the quality process ensuring great parts that have been produced are delivered safely and on-time. While machining custom parts that meet exacting customer specifications is China Machined Parts’s core functionality our dedicated shipping team is responsible for the following steps, right up to loading parts on trucks, that are critical to quality;
Upon completion and prior to shipping the stamping content is double checked by our quality team.
While shipping is a prerequisite for any manufacturer it’s taken to the next level at China Machined Parts. We take pride in ensuring that the parts we produced arrive at our customer’s facilities on time and in the same high quality that they left our facility.
At China Machined Parts, Ltd.s, we have extensive experience operating honing equipment that improves the geometric form and surface texture on pipes, tubes, cylinders, and liners. In honing operations, a rotating tool carrying abrasives removes metal from the interior surface of a bore or cylinder. The main purpose is to finish the surface to a particular diameter and geometric cylindricity. It’s almost always a secondary machining operation that finishes a part or relieves stress. A typical production cycle is to rough turn the OD, bore the ID, hone, finish turn and complete any required mill work. The honing operation typically removes from 0.001” to 0.010″ (0.03-0.3 mm) of material.
Although the honing process can be applied to any surface, it is most commonly done on internal cylinder walls using a combined rotating and reciprocating motion. Low cutting pressure, low velocity, and relatively small amounts of material removal characterize it. Typical speeds are around 250 fpm (76 m/min). However, unlike conventional machining, higher speed is not always an advantage. Each application has a honing abrasive chip load which is a limiting factor. With abrasive honing stones, the proper choice of bond and coolant optimizes stone performance and cost per part.
We typically utilize abrasive stones that are used along a controlled path to remove minute amounts of material in order to attain almost perfect cylindricity on parts. Unlike conventional machining, the accuracy of a honing process is not entirely dependent on the machine. The tool and abrasive are the keys to accuracy. Another difference from conventional machining is that it needs no chucking or alignment. The part aligns itself with the tool because the tool or the part is floating in most applications. Often, the part is placed in a specially designed honing fixture that provides floating action.
Honing machines allows precise size, surface finish, roundness, straightness and consistent surface texture to be achieved. And with our equipment we can achieve surface finishes between 6-8 RMS with tolerances as tight at +/-0.001″ or meet virtually any customer specified requirement. Our facility is equipped with a Sunnen Model HL 80 precision horizontal hone that handles diameters from 3″ to 22″ with a 60″ stroke. We also have a Sunnen Model MBC-1805 hone with auto sizing and power stroke capability; accommodating diameters ranging from .160″ to 3.5″ with a 6″ stroke.
Since China Machined Parts’s inception, and with three decades of operations, machining natural gas compressor parts is in our DNA. As an AS9100D / ISO 9001:2015 certified contract manufacturer focused on CNC machining of larger diameter (2” to 42” turned and 2” to 30” milled) production parts China Machined Parts has significant experience machining to print parts for a diverse group of players in the natural gas compression market. Over almost 30 years China Machined Parts has manufactured compressor parts gaining invaluable knowledge including;
With years of experience China Machined Parts possess a diversity of knowledge not only with different parts but also diverse materials. From bar stock, castings and forgings we’ve machined parts from materials including alloy steel, aluminum, cast iron, titanium, and nickel based alloys.
Based on this expertise China Machined Parts can take on a wide variety of production parts for your organization.
