CNC Machined Steel Hydraulic Valve Sleeve 40Cr 42CrMo 20CrMnTi SUJ2 Fluid Control Component
Polestar offers custom fittings for many diverse industries including electronics, instrumentation, automotive, computers, aerospace, medical and dental. We can manufacture bushings and sleeves with many features, such as precision holes, multiple holes and lubricating voids.
Bushings and sleeves are typically used in hydraulics and machine tools. Bushings offer complete protection for soft, brittle materials. They also enhance the strength and rigidity of the assembly in which they are used. Secure alignment of components can be obtained through our bushings and sleeves.
Bushings and sleeves are machined through rigorous milling and turning techniques. Our fittings can be manufactured to extremely precise specifications; with tolerances of ± 0.0001 inches and surface finishes to 16 micro. Secondary services like broaching, grinding, heat treating, plating, tapping, thread rolling and tumbling are offered to enhance and improve all bushings and sleeves.
Precise dimensions are achieved through the use of our Tornos Swiss Automatic Screw Machines, Tornos and Citizen Swiss CNC Turning Machines. Also, we use Statistical Process Control (SPC) throughout the manufacturing process. All custom machines parts are available in diameters ranging from 0.005 to 1.00 inches and lengths ranging from 0.005 to 10.00 inches. Other specifications include tight tolerance values down to ± 0.0001 inches and surface finishes to 16 micro.

Combining CNC Machining with Other Processes
CNC machining is a versatile manufacturing process, and its synergy with other complementary processes can unlock new possibilities in terms of complexity, precision, and material variety. In this exploration, we will delve into how combining CNC machining with other processes enhances manufacturing capabilities across various industries.
CNC Machining + Laser Cutting
Combining CNC machining and metal cutting laser cnc creates a powerful synergy in manufacturing. A metal cutting cnc laser provides precision and versatility in material processing, producing intricate patterns and fine details.
Integrating cnc metal laser cutting machine complements this by offering accuracy in complex features and surface finishes. The union of these technologies enhances design freedom, reduces material waste through optimized nesting, and enables the efficient production of components across various industries.
Metal cnc laser cutting machines result in a streamlined manufacturing process that achieves both intricate detailing and precision, making it a preferred choice for applications ranging from automotive components to electronics and consumer goods.
CNC Machining + Aluminum Extrusion
The method of cnc aluminium extrusion involves pushing molten material through a die’s opening to create an extended component with a continuous profile. Although cnc aluminum extrusion is a useful process for creating functional parts with high-quality surface finishes and intricate cross-sections, its use is restricted since the cross-sections must be uniform throughout the item.
Unless, of course, extrusion results in modifications to the component. The pieces produced by extrusion of aluminum can be post-machined, or cut in different ways, using a CNC milling aluminum machining center, because extrusion often involves malleable, ductile, and machinable grades of aluminum, such as 6061 and 6063. Creating strong products with intricate cross-sections and asymmetrical geometries is a terrific idea when combining extrusion and CNC machining.
