See why our customers love us

Professional

I worked with another Chinese machine shop for eight years, and while the relationship was initially great, I eventually became disappointed by quality issues, late delivery and complete lack of communication. So I decided to give Leshine a chance with a small order. Not only did they deliver on schedule, they did it with 100% accuracy and attention to detail. It was the same with my next order.
Professional

I took a risk using Leshine, as I hadn’t used them before. I sent them some very challenging, high-tolerance, CNC machined parts (some with machining from six sides), with some really small details.
Hours Service

We have been ordering CNC parts from Leshine for over 5 years. Their quality and services are way better than what we can get from the other Chinese CNC machine shops. We always receive a fast quotation after we send through RFQs. Normally, within 12 hours or shorter which helps a lot.
Professional

We came across Leshine when the first time we try to outsource CNC machining parts from China. They came back with a price, lead time, and suggestions in 5 hours. Seriously, I was shocked by their fast reaction and professional idea to improve the design.

CNC Turned Parts

CNC lathes allow us to get high-speed turning of both plastics and metals from bar or block material. The turning process allows the production of complex external and internal geometries, including generating all kinds of threads. For any round shaped components, for example, shafts, worms, spheres, CNC turning is a more efficient method compared with CNC milling. Leshine’s turning capability can make prototypes all the way through mass production parts.

Applications of CNC Machining

Design & Rapid Prototyping

Regardless of the manufacturing process used to create the end-use part, CNC machining is widely used by designers as a means of creating early and late-stage prototypes with short turnarounds times. CNC prototyping allow designers to rapidly iterate ideas without tooling costs or waiting times. It is one of the best ways to create concept model and function prototype to verify the design. Compared with other rapid prototyping methods, CNC machining allows us to get tight tolerance prototypes in real materials.

CNC Prototyping is the preferred option to bring new design life among the other rapid prototyping methods, unless the products are designed for 3D printing or other methods only.

Mold Making

CNC machining and EDM are the main methods to fabricate metal tooling for injection molding, high pressure die casting, blow molding, roller molding, stamping, blending and so on.

High speed CNC machines allow us to make high precision copper patterns, mold cavities, mold base, lifter and other mold components in very short term. Moreover, with 5 axis milling machines, we can mill the deep pocket features in hours which take days to make by EDM in the past. That’s how we can speed up the mold making process significantly. Check out how rapid tooling works.

Aerospace

CNC machining has for several years been an integral part of aerospace manufacturing. That’s partly down to the extremely high precision of CNC machines, making the process suitable for safety-critical parts that will be used on aircraft.

Machinable aerospace parts include prototype engine components, fuel panels, landing gear components and engine mounts.

Automotive

In the automotive industry, CNC machining is the most popular way to create concept cars as well as the function testing components, such as lighting, engine, transmission & steering system. It is also widely used to produce high volume automotive parts and post-machining the die casting parts, investment casting parts.

It is especially useful for custom automotive parts, which may be required for repairs or for limited-edition luxury vehicles, since it is too costly to make few parts by molding process.

Medical

The machinability of many grades of titanium and stainless steel makes CNC machining a widely used process in healthcare, with the process regularly used to create implants, medical devices and surgical tools such as scalpels.

Tight tolerances and fast turnarounds are especially important for items such as titanium hip implants, which should be tailored to a patient’s anatomy.

Consumer Products

Though injection molding dominates the production of simple plastic parts, many off-the-shelf goods are created with CNC machining. Household goods and appliances often contain machined parts, while items like enclosures and fixtures are also suitable for the process. Goods like sporting equipment may also be CNC machined. The CNC machining of metal and plastic components plays a big role in the electronics industry. Items such as laptop casings, connectors and sockets can all be reliably made with a CNC machine.

Standard Tolerances

With high precision milling & turning machines, we are able to catch super tight tolerance for prototype machining & production. Parts will be made accordingly to our customers’ specification. If 2D drawings are not available, you can also indicate with ISO 2678. The table below is the ISO 2678 standard for your reference.

Tolerance Lever				Overall Dimension Range
Specifications	<<3, >0.5	<<6, >3	<<30, >6	<<120, >30	<<400, >120	<<1000, >400	<<2000, >1000
Tolerance Standard
F	±0.05	±0.05	±0.1	±0.15	±0.2	±0.3	±0.5
M	±0.1	±0.1	±0.2	±0.3	±0.5	±0.8	±1.2

Precision Machining

Aside from standard tolerance CNC parts such as ISO2678M or ISO2678F, 3ERP also offers high-precision CNC machining parts.

After being in the manufacturing industry for over 10 years, we discovered a simple formula to produce precision parts
Precision machines + Precision heart = Precision parts.

Leshine has a wide range of CNC machines and experienced engineers who never compromise with tolerance or part quality.

Plastic Machining

Many plastics are suited to CNC machining, and machined plastic parts can be superior to their molded or printed counterparts. At Leshine, we can machine parts from high-quality materials like POM, PEI and PEEK.

Machining is often the best choice for high-quality plastic prototypes with detailed features, both because of the technical advantages of the process and the material versatility associated with it.

All machined plastic parts are handled with care by our expert team of machinists.

Aluminum Machining

Aluminum is one of the most popular machining materials thanks to its workability, strength and versatility, while its low cost makes it perfect for prototypes and productions. From standard grades like 6061 to high-quality aerospace grades like 7075, we have an aluminum alloy for every aluminum CNC machining project.

Aluminum is not as hard as steel, so we can cut it much faster comparing steel or stainless steel when milling aluminum parts. On the other hand, 5 & 6 series of aluminum gives perfect result of anodized which is widely used for electronic appliance.

Our team has rich experience of aluminum machining, since more 70% of parts we are making is aluminum.

5 Axis Machining

5-axis machining is the best solution for complex and precise machined parts. When using 3-axis or 4-axis milling for parts that are designed with deep pockets or features that must be cut from multiple angles, we have to set up the machine many times. And the more we have to reload the part, the less accuracy we get. With 5-axis milling, we only have to set up the machine once or, at most, twice, and by using an on-site inspection system we can easily get the correct coordinates when we reload the part.

Most our engineers have over 5 years programing experience of 5-axis machining, which enable us to provide 5-axis machined parts in metals, plastics or other materials with fast turnaround.
