Precision Machining

We know precisely what you

need when it comes to Precision Machining

Venturing into the 20th century, equipment and machines have become increasingly complex. Many high-precision parts are difficult to make with conventional processes. Manual machining can no longer fulfil the needs of the manufacturing industry. In 1952, the first CNC milling machine was developed, marking the birth of this amazing technology.

CNC (Computer Numerical Control) machining employs computer-controlled machine tools functioning under numerical control to create highly complex parts. Various aspects of the process (feed rate, machining location, speed and coordination) can be customized to meet specific requirements of a part. Our CNC workshops utilize a variety of 3-axis to 5-axis CNC machines, including Chinese made and imported machines from the US, Japan and Taiwan.

Materials

Aluminium, brass, magnesium, nickel, steel, zinc, titanium and many alloys, as well as wood, foam, fiberglass, plastics and polymers can all be CNC machined.

Tolerances

CNC machining tolerances may vary depending on the material and CNC machine type. Typical tolerance standard is set to ±0.005″/0.13mm, but most CNC processes can have even tighter tolerances. For more details on the tolerances of each CNC process, please refer to the sections below.

CNC machining processes we provide

As an all-round manufacturing service company, Omnidex provides a plethora of CNC machining solutions, including CNC Milling and CNC Lathe:

CNC Milling

CNC milling machines use rotating multi-point cutting tools to progressively remove unwanted material from a block of material. We use a range of 3, 4 or 5-axis industrial grade CNC milling machines for our CNC milling work. 3-axis machines can move the milling tool (or the workpiece) on the 3 linear X, Y and Z axes, while 4-axis and 5-axis machines add the rotating A and B axes to the equation.

• Maximum part size: 20 m x 4 m x 3 m
• Maximum machining area: 12 m x 3.5 m x 2.5 m

Why Choose CNC Milling Services?

CNC are applicable to a wide range of materials. Almost any engineering plastics or metals can be milled to make custom parts.

Milled parts are highly repeatable, highly repeatable, and possess high dimensional stability.

With high adaptability and flexibility, CNC milling is one of the most versatile machining processes.

CNC milled parts can be manufactured in several processes from a single set up; CNC milling can be performed at the same time on multiple surfaces.

CNC milling services are ideal for parts with complex shapes or tight tolerances, such as mold components or housing components.

CNC milling machines are very automated, producing high levels of efficiency, and can be run continuously 24/7, so production management can be automatized.

CNC milling with 3-Axis, 4-Axis, and 5-Axis

3-Axis is one of the most widely used techniques for milling parts. CNC mills typically have 3 axes, which allow the work-piece to remain stationary while the cutting tool moves along the X, Y, and Z axes.

3-axis mills can be used to drill holes, cut sharp edges, and mill slots due to the ability to work with all three axes. Despite its simplicity, this mill allows the material to be removed in 3 directions: backward, sideward, and upward.

The 4-axis mill is used to make parts that are more complex. The machine has the advantage of providing additional flexibility as it rotates on a vertical axis, allowing for more continuous machining.

This technique uses the same techniques as 3-axis milling, but milling takes place on an additional axis, i.e. A 4-axis CNC machine operates on the X, Y, and Z axes in addition to rotating on an X-axis (also called as the A-axis).

CNC mills with five axes are the most advanced and widely used. It can accommodate three axes traditionally used and two extra degrees of movement. A rotating spindle and worktable are used together. Its main advantage is that it can machine five sides of a workpiece in one setup, so it can be positioned in a variety of positions.

Five-axis machines are the most advanced in the market right now: they can be used for precise medical devices, aerospace parts, titanium pieces, and oil and gas machine parts. With this machine, you can easily machine CNC parts in one step, reducing your production time. Furthermore, it makes complex geometry easier to access and increases tool life.

We offer CNC machining services to support your production parts milling.

Metal or plastic parts milled from more than 30+ certified materials.
From prototype to production, get custom parts at consistently low prices.

CNC Lathe (Turning):

CNC lathe tolerances:

CNC lathe machines rotate the work-piece with a spindle while a fixed cutting tool slices the unwanted material away. This process is used to produce cylindrical parts that are symmetrical around the same axis.

•  Maximum part diameter: 2.5 m

Benefits of Precision CNC Machining

In comparison with manual machining, CNC machining can produce very precise and complex shapes. In addition to being more precise, also allows for repeatability, allowing the same product to be delivered with similar specifications time after time. Due to its repeatability, consistency and level of precision, it is used in the production of many three-dimensional shapes that are complex in nature. Additional benefits of CNC machining include:
Additional benefits of CNC machining include:

A CNC machine has the ability to perform the simultaneous motion, resulting in the ability to achieve three-dimensional contouring.

A high-pressure coolant helps to keep the cutting zone cool and clean, improving productivity.

Since CNC machining ensures consistent accuracy, it is possible to mass-produce identical parts since once a part has been produced, it can be repeated ensuring consistent product quality.

Once a CNC machine has been loaded for the first time, it is capable of automatically changing tools, increasing productivity.

Deep and large cuts can be produced by CNC machines.

We may offer other specialized CNC processes based on your requirement. Please consult our Sale Department for more information.

CNC machining is different from conventional machining processes in many ways. The use of computer software to control the machining tools adds a lot of benefits, and in many cases can negate the higher equipment and production costs, making them the ideal solutions for small production of precision parts or fast prototyping.
