Stainless Steel KF Vacuum Flange
Stainless Steel KF Vacuum Flange is a component or assembly manufactured by machining. Stainless steel is a hard and viscous material. Regarding processing complexity, it is about three times superior to softer metals, like aluminum. This means that to make a part from stainless steel, the machine must make three times as many passes. And the tool, which performs processing, wears out faster. But this is not a problem for us.
The ISO-KF system is a modular, building block method of creating a piping system. There are several advantages to the use of Stainless Steel KF Vacuum Flange. Since component dimensions are standardized, elbows, tees, crosses, or valves for a given size may be interchanged. These KF-50 90-degree elbow vacuum fittings follow ISO-KF standards and have a flange size of NW-50. They are commonly used to build fireline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges (please see top right figure – click to enlarge). The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of corrosive-resistant stainless steel.

Possibility of replacement by other materials
It is not an easy task to find a material that would not be inferior to stainless steel in terms of aesthetic qualities, strength, and corrosion resistance. Carmakers usually use carbon fiber, while manufacturers of equipment for restaurants – use alloys of non-ferrous metals. We recommend you consider making Stainless Steel Turned Parts from less expensive grades of steel or aluminum, together with the subsequent anodizing.

Frequently Asked Questions
The following parts are a good fit for CNC turning:
Rotary parts with high precision requirements.
Rotary parts with complex surface shapes.
Rotary parts with lateral machining.
Ultra-precision and ultra-low surface roughness parts.
Parts with special threads.
The main costs related to CNC machining can be divided into machining time, start-up cost, material cost, and feature cost. To reduce costs, you need to understand the impact of these factors on costs.
– The best way to reduce machining time is to design features that can be processed quickly, such as by selecting the correct inner corner radius, reducing the cavity depth, increasing the wall thickness, limiting the thread length, and designing holes of standard size.
– The material cost can be reduced by considering the size of the required blank and the cost and machinability of bulk materials (softer alloys process faster).
– Start-up costs can be reduced by reducing the number of part rotations or repositioning required to complete the part, such as dividing the geometry into multiple parts that can be assembled later.
– Using tolerances only when strictly necessary, deleting all text and letters, and avoiding multiple surface treatments can reduce feature costs.

CNC turning is used for creating a variety of parts, including auto parts, knobs, tubes, gears, toy parts, flywheels, crankshafts, hubs & disc cams. It is most often used to manufacture CNC parts online for automotive, aerospace, medical, and other industries.
CNC turning center, the equipment or machines for CNC turning service, is a computer-controlled 3, 4, or 5-axis machine that has capabilities of turning, drilling, tapping, and milling, using live tools with powered rotary tool turret, dual spindles, Y-axis, and multiple turrets. While the CNC lathe machine is a simpler 2-axis with one spindle, basically composed of headstock, carriage, tailstock, and bed.
– CNC turning centers have more complex structures than CNC lathes.
– CNC turning centers have higher production capabilities and versatility than CNC lathes.
– CNC lathes are generally flat-bed type while turning centers are usually slant-bed type.
– There are only minimal protective enclosures around the lathe while the turning center is commonly equipped with full enclosures to keep chips and coolant splashes within the machine.
Heat treatments can be applied on precision CNC turned parts to improve their key properties such as hardness. Heat treatment can be applied to metal parts throughout the manufacturing process.
– Hardening: used to harden the material and make it stronger, also decreases the ductility.
– Annealing: heats metal parts to a very high temperature and then slowly cools to achieve the desired microstructure.
– Normalizing: used to relieve internal stresses that were created during machining service.
– Quenching: heating the metal to a very high temperature, followed by a rapid cooling step.
There are many types of CNC turning operations for CNC lathe services that can be performed on a live tooling lathe in CNC turning factory, including Hard turning, Parting, Facing, Boring, Reaming, Taper turning, Drilling, Knurling, Threading, Grooving, etc., comes in varying tools, cost and set-up time.
– Tapered turning: produce a cylindrical part of which diameter decrease from one end to another.
– Hard turning: suited for materials with a Rockwell C hardness greater than 45, typically performed after heat treated.
– Spherical generation: create a spherical finished surface, turning around a fixed rotary axis.
– Facing: a turning operation in which the workpiece is machined to its center.
– Parting: create deep grooves that remove a completed or part-complete component from its parent stock.
– Grooving: similar to parting, but only cut to a specific depth from outside or inside of the workpiece.
– Drilling: remove materials to drill holes from the inside of a workpiece with drill bits held stationary in the tailstock or tool turret of the lathe. Boring: enlarge or smooth an existing hole.
– Knurling: cut a serrated pattern onto the surface of the workpiece with a knurling tool, to change or enhance the visual effect or hand grip.
– Reaming: remove a small volume of materials from a drilled hole, for highly accurate diameters.
– Threading: turn standard and non-standard screw threads, which generally means single-point threading.
– Polygonal turning: non-circular forms machining operation without interrupting the rotation of the raw material.
