Which Machining Services are Right for You?
Machining is a manufacturing concept that refers to various technologies and processes that extract material from a workpiece using power-driven machine tools to transform it into a desired shape or design. During the manufacturing process, most metal components and parts need some machining. Other products typically manufactured using machining processes include plastics, rubbers and paper goods.
Types of Machining Services
Machining services offer a variety of technologies and processes to cater to a specific customer need. With that, here are some of the more well-known types of machining services:
A milling tool is a tool that uses a rotating cutting surface with several blades. Milling uses a rotating cutting surface to create non-circular holes or cut unique designs out of a chosen material.
A turning tool rotates a workpiece on its axis while a cutting tool shapes it to form. The most popular form of turning machines is a lathe.
Drilling uses drill bits to make cylindrical holes in solid materials, making it one of the most critical machining processes. The holes made are often used to help in assembly. Drilling is the first step in making finished holes, which get tapped, reamed, bored, and so on, to make threaded holes or put hole dimensions within suitable tolerances.
Drill bits will normally cut holes larger than their nominal size and holes that may not be inherently straight or round, owing to the drill bit’s versatility and propensity to follow the path of least resistance. As a result, drilling is often defined undersize and accompanied by a machining operation to bring the hole to its final size.
Forming or Bending
Forming is a metalworking process that involves deforming metal parts and objects mechanically. The workpiece gets reshaped and transformed without adding or removing material while retaining its mass through forming or bending.
Grinding is a technique for removing tiny quantities of material from flat and cylindrical surfaces. More specifically, surface grinders feed work from a table into a grinding wheel in a reciprocating motion.
Lapping and Polishing
Lapping is a machining process that involves rubbing two surfaces together with an abrasive between them, either by hand or by machine. As the abrasive rolls between the two surfaces and extracts material from both, microscopic conchoidal fractures form.
Welding and Post-Weld Machining
Welding machines, welding arms and welders are among a welding professional’s most important equipment. Welding machines produce heat, which melts metal parts and allows them to join together. The best single welding machines differ depending on the type of project.

Multi-Axis Machining Services
As established, milling is among the foremost and most essential processes in any machining service. Milling removes material from a workpiece by feeding it at an angle to the tool’s axis with rotary cutters. A milling machine’s axes decide the type of work performed and where you can do it on the workpiece.
With that, here are the most common types of Milling:
3-axis machining is a milling process that operates on three axes — the X, Y, and Z axes — and originated from the technique of rotary filing. In 3-axis milling, the workpiece remains stationary while the cutting tool mills the component along the three axes. 3-axis machining is still one of the simplest and most common methods for producing mechanical parts, and you can use it to mill slots, drill holes, and cut sharp edges in a back to front, side to side or up and down fashion.
Furthermore, 3-axis machining is suitable for most machining projects, depending on the scale of the production run, the workpiece specifications, accuracy and finish constraints, materials used, and holding capabilities.
The processes involved in 4-axis machining are the same as in 3-axis mmachining, but with an additional axis. 4-axis milling rotates around the X-axis, the fourth axis known as the A-axis, in addition to 3-axis milling’s X, Y and Z axes.
Milling comes in handy when holes and cut-outs are needed on the side of a piece or around a cylinder, 4-axis. They can produce accurate results with fast and efficient work based on computer numerical inputs.
5-axis machining encompasses all the axes in 4-axis machining, with an additional rotational axis — the B-axis — which rotates around the Y-axis. With its capability of producing precise and intricate parts for a wide range of items and pieces, 5-axis milling machines have earned the reputation of the best CNC milling machines today.
The B-axis’s unparalleled precision, finish and pace in creating a piece are attributable to its multidimensional rotation and tool movement. Furthermore, 5-axis machining allows for the development of highly complex, intricate components.
You can turn any component and multi-axis milled in a single setup thanks to the nine working axes. The removal of manual loading and secondary fixtures is the most significant advantage of this machine.
A fully finished product can get produced on a 9-axis unit. Thus, it achieves the highest level of precision by obviating the need for additional operations, resulting in an actual “done-in-one” output.
Machining Using Horizontal Milling
Horizontal milling machines help when precision is not a big factor, the material is challenging to work with, and grooves need to be thicker or deeper. Horizontal milling machines can work faster than vertical milling machines, and their finished products have smoother surfaces. Gravity also assists with taking the chips out of the material. This aid is due to the configuration of a horizontal milling machine, requiring less fabrication at the end of the work.
Machining Using Vertical Milling
A vertical milling machine has a wide range of applications. These devices can easily be modified and maneuvered to cut a wide range of shapes, allowing them to work on a wide range of projects. While manual movement is still needed to cut in various directions, vertical milling has several advantages, including low maintenance and high functionality.
