Our CNC Machining Services

If you need custom machined parts with complex geometries, or get end-use products in the shortest possible time, Kesu Hardware is good enough to break through all of that and achieve your idea immediately. We operate over 100 sets of CNC machines, CNC Lathe, CMM, and offer different types of materials and surface finishes, guaranteeing quick turnaround and quality of one-off prototypes and production parts.

What is CNC Machining?

CNC, or computer numerical control machining, is a widely used manufacturing process that uses automated, high-speed cutting tools to form designs from metal or plastic stock. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. Machines may vary in how CNC parts are cut—the workpiece may remain in place while the tool moves, the tool may remain in place while the workpiece is rotated and moved, or both the cutting tool and workpiece may move together. 

Skilled machinists operate a CNC machine by programming tool paths based on the geometry of the final machined parts. The part geometry information is provided by a CAD (computer-aided design) model. CNC machines can cut almost any metal alloy and rigid plastic with high precision and repeatability, making custom machined parts suitable for nearly every industry, including aerospace, medical, robotics, electronics, and industrial. Kesu Harware provides CNC services and offers custom CNC quotes on over 40 materials ranging from commodity aluminum and acetal to advanced titanium and engineered plastics like PEEK and Teflon.

Advantages and Challenges of CNC Machining

Advantages of CNC Machining

CNC milling and turning are highly accurate and repeatable processes. Tight tolerances between +/-0.001″ – 0.005″ can be achieved, depending on specifications. Machines can be programmed to reliably run for 24 hours, 7 days a week if necessary, so CNC milling is a good way of getting parts produced on demand.

Using standard tooling, a CNC machining service is particularly valuable for creating one-off parts, custom CNC parts, i.e., for replacing legacy components or delivering a specialized upgrade to a customer. It is also conceivable to scale single-part production to runs exceeding 10,000 units. Depending on the unit number, size, and complexity, the turnaround for CNC machined parts can be as short as one day. With shipping and delivery, deadlines can be met within a week.

Another primary advantage of CNC technology is its achievable mechanical properties. By cutting away from bulk material, rather than thermally transforming it as in injection-molding or additive manufacturing, all desirable mechanical properties of the metal or plastic of choice are retained. More than 50 industrial-grade metals, alloys, and plastics can be machined using CNC milling and turning. This selection includes aluminum, brass, bronze, titanium, stainless steel, PEEK, ABS, and zinc. The only material requirement for CNC machining is that the part has an adequate hardness to be fixtured and cut.

Challenges of CNC Machining

One trade-off when taking advantage of the high performance of CNC machining processes is that geometric complexity comes at a cost. Simple, chunky parts are the best designs for CNC milling and turning. There will always be some design limitations due to tool access, although the degree of this effect is relative to the number of axes on the machine. In other words, the more axes used, the more complex the features can be achieved.

Another trade-off is that start-up CNC machining costs can be expensive. It is necessary to have a trained professional perform the setup, tool loading, and programming on CNC mills and lathes. Luckily this cost is fixed, so by taking advantage of the same setup for multiple parts, it becomes more economical. Saving money is also achieved by keeping part repositioning to a minimum. Machining at 5-axis and above can sometimes be more economical on multi-faceted geometries because it eliminates the need to manually reposition the part.

The wire EDM method of machining can be slow and expensive relative to other processes, and the range of materials that can be used is shortened as they must be electrically conductive.

Kesu Harware works with leading manufacturers from different industries to support growing demands and streamline their supply chain. The digitalization of our custom CNC machining services helps more and more manufacturers bring their idea to products.
