On-Demand CNC Machining Service
CNC machining, or Computer Numerical Control machining, is a manufacturing process that utilizes computerized controls to operate and manipulate machine tools. It involves the use of computer-aided design (CAD) software to create a digital model of the desired part or component, and then translates that model into a set of instructions that control the movement and operation of CNC machines.

CNC Milling
CNC milling is a subtractive manufacturing technique that utilizes a cutting tool to traverse and rotate, eliminating material as it progresses. CNC mills excel at cutting and machining operations involving diverse plastic and metal materials. It is applicable to any industry that demands accurate components and serves as an optimal instrument for crafting molds.
CNC Turning
CNC turning eliminates material by engaging a cutter with the rapidly rotating workpiece and is commonly employed to fashion cylindrical or tubular forms. The CNC turning process facilitates the creation of intricate external geometries and internal cavities, encompassing the machining of diverse threads.5-Axis CNC Machining
5-axis CNC machining enables the processing of intricate parts with multiple side features, allowing up to five sides to be worked on in a single setup. This can yield significant advantages in terms of enhanced machine utilization, decreased setups and cycle times, and improved quality. The versatility of 5-axis machining will render our CNC shop more economically viable for a broader spectrum of projects.Precision CNC Machining

CNC Plastic Machining
Over 30 engineering-grade materials can be utilized for CNC plastic machining. The machined plastic parts are fully functional and capable of undergoing mechanical testing.
CNC Metal Machining
Whether it is prototypes or final products, our expertise in CNC metal machining techniques enables us to achieve tighter tolerances, quicker turnaround times, and more demanding manufacturing projects.
CNC Machining Tolerances
Leland standard tolerance is applied to ISO 2768 (medium) for machined plastic and ISO 2768 (fine) for machined metals. Typically, we can hold a CNC machining tolerance from ±0.005″ (±0.125mm) to ±0.002″ (±0.05mm). If tighter tolerances are required, a 2D drawing with complete information will be necessary. Our engineering team will communicate with you the critical dimensional tolerances and provide the highest degree of precision possible.
Design For Manufacturability
A Quick Guide To Designing CNC Machined Parts
As large an internal radius as possible
Any internal cut will generate a fillet that is half the diameter of the tool used. Milling with smaller tools takes a long time and we recommend that the radius should be greater than 1/3 of the depth of machining. The best bet is to relieve internal corners or allow for as large an internal radius as possible on mating part designs and use the same radius on all inside edges so that the same tool can be used throughout the CNC machining processes.
Avoid overly deep cavities, grooves and holes
The depth of the cavity and groove is usually related to the diameter of the tool used to make the internal fillets, and a good rule of thumb is to keep the cavity depth 3 – 4 times the tool diameter or the groove depth less than 4 times the feature width. Whether blind holes or through holes, the recommended maximum depth is 4 times the diameter and the minimum hole diameter is 1 mm, and it is recommended to design standard size holes. With a standard drill, holes can be machined quickly and with high precision; for non-standard holes, using an end mill will increase costs.
Avoid thin walls
As with tall walls, vibration increases when machining thin features. As a guide, the minimum thickness of thin-walled metal parts should be 0.5-0.8 mm, and the minimum thickness of plastic parts should be 1.0- 1.5 mm. If the walls are for supporting action or taller features, the wall thickness should be increased to avoid vibrations during CNC machining processes.Avoid small or raised text
You may need to mark parts with part numbers or company names. Adding text looks really cool in the custom CNC machining, but is time-consuming to process; electrochemical etching or laser marking is usually better. If you must cut text, choose recessed rather than raised text whenever possible, keep it simple and large, with a font depth of no more than 0.3mm.

CNC Machining FAQs
We offer product developers parts machined from engineering-grade materials that are suitable for functional testing or end-use applications. Get the support you need on CNC machining and engineering information by reading the FAQ here.
What kind of CNC machining services do you offer?
CNC machining is also called computer numerical control machining. We do the following machining services: milling, turning, drilling, threading, tapping, EDM and wire EDM, custom surface finishing, prototype machining, low volume or one-off part machine runs, modification of an existing part, material sourcing assistance, limited material warehousing and parts dispatching.
From prototype to production, from 1 to 10,000 pieces, we offer fast turnaround CNC machining of your custom metal and plastic parts with as fast as 3-day delivery.
What are your CNC machining capabilities?
Leland has a 35,000 square foot CNC machining shop. With 60+ skilled employees and 16 high-performance CNC machines, maintain 24/7 operations and can deliver over 300 machining projects and 20,000+ machined parts per month in our CNC machining centers.
What is the typical cost of a CNC machined part?
Our engineering and sales teams will provide one-on-one quote support for your project. Typically, for similar parts, CNC lathes cost 15% less to machine than standard 3-axis CNC milling. In contrast, the cost of 5-axis machining increases, continuous 5-axis CNC milling typically costs over 20% higher than an indexed 5-axis machine (also referred to as 3+2 milling), and about double that of a standard 3-axis mill. To achieve the most cost-effective CNC machined parts, larger production runs are recommended to spread the cost of machine setup.
What are the maximum size ranges of your machine travel?
Maximum Dimensions (3-axis milling): 1270×508×635 (mm).
Maximum Dimensions (5-axis milling): 450×700×400 (mm), Worktable Diameter Φ400 mm.
What kind of surface finish does CNC machining leave?
Once the machining process is complete, the CNC parts surface will have slight visible tool marks, called “as-machined” or “as-milled” surface finish. Machined surface roughness (Ra) is standardized at 1.6-3.2 μm, and surface finish requirements can be increased to 0.8-1.6 μm or higher at 0.2-0.8 μm, however, this will require more operating time and higher costs.
