Parts requiring precision machining come in a variety of materials such as iron, stainless steel, bronze, graphite, plastics, steel and other metals. Depending on the size of the application scenario and the materials involved, a variety of precision machining tools and techniques will be used. As a result, precision machine tool operators can use any combination of drilling machines, grinders, lathes, milling machines and even industrial robots to get the job done.

Precision machining is a process that produces accurate parts with high tolerances and excellent surface quality by removing material from the workpiece. Precision machining processes can involve turning, milling, drilling, gear cutting, grinding and other processes. Heat treatment is a special process such as carburising, quenching, tempering, etc., which may be employed for special needs during precision machining. Precision machining usually requires computer numerical control or CNC programming, which allows special designs to be converted into precise shapes through multiple dimensions

Features of precision machining

Reduced waste of raw materials, the introduction of advanced precision technology reduces the waste of part materials. Although a certain level of waste is expected in engineering and manufacturing, the application of precision machining will significantly reduce waste. This significantly saves manufacturing costs, protects the environment and maximises the use of expensive materials.

Precision machining improves productivity and precision engineering requires the use of machines with automated assembly capabilities. This means that production times are greatly reduced and large orders can be accepted at a given time. Precision machining maximises the use of advanced precision technology to speed up production. Precision machining provides customers with fast turnaround deliveries and reliable service. When the production cycle is faster, it does not mean that the quality decreases. Specialist precision engineers will maintain quality throughout all machining processes to ensure a finished product of the desired size is produced.

Precision machining allows for the machining of workpieces that require a high degree of accuracy. Precision machining is the ability of machinery and technology to accurately and precisely manufacture parts to exacting specifications. The ability of precision machining refers to the level of accuracy with which a supplier can manufacture parts, objects or assemblies, whether large, complex, tiny and with high accuracy requirements. Maintaining this level of precision across a range of different object sizes and shapes is essential due to the extreme level of precision and accuracy required to manufacture many parts.

What equipment is used for precision machining

There are many pieces of equipment used for precision machining, such as CNC milling machines, CNC machining centres, CNC drilling machines, CNC grinding machines and CNC lathes. The following section will briefly describe some of these CNC milling machines, which vary in size, axis configuration, feed rates, cutting speeds, milling feed direction, and other characteristics. However, in general, CNC milling machines use a rotating spindle to remove unwanted material. They are used to cut hard metals such as steel and titanium, but can also be used for materials such as plastics and aluminium.

CNC mills are designed for repeatability and can be used for everything from prototyping to high-volume production. High-end precision CNC milling machines are often used for precision tolerance work, such as milling fine moulds. While CNC milling can provide a quick turnaround, finishing after milling creates parts with visible tool marks. It can also produce parts with some sharp edges and burrs, so additional processes may be required if edges and burrs are unacceptable for these features. Of course, the deburring tool programmed into the sequence will deburr.

Precision CNC milling centres are available with multiple axes. 3-axis CNC milling machines utilize the X, Y and Z axes for a variety of tasks. With a 4-axis CNC milling machine, the machine can rotate and move the workpiece in both vertical and horizontal axes for more continuous machining.A 5-axis CNC milling machine has three conventional axes and two additional rotary axes that allow the workpiece to rotate as the spindle head moves around the workpiece. This allows machining of all five sides of the workpiece without removing the workpiece and resetting the machine.
