What Are Precision Machining Services?
Precision machining is often used for parts that require a close tolerance. Using a computer numerically controlled machine or specialized lathe, a precision machinist can manufacture complex parts with precise specifications.
Precision machining is used on a wide variety of metals including steel, aluminum, and brass as well as other materials like ceramics and plastics. Depending on the raw material, various machines are used. A machinist may need to use lathes, drill presses, milling machines, and high-speed robotics to remove material from the workpiece.
Most machining today is completed with computer numerical controls (CNC) machines and computer-aided design (CAD) software such as AutoCAD. The machine shop may also use computer-aided manufacturing (CAM) programs.
Most designs rely on CAD/CAM programs. However, the designs typically start as sketches in the initial development phases. The software allows machinists to take hand-drawn sketches and convert them into three-dimensional diagrams.
Precision CNC Machining
Advanced high precision machining often involves the use of a CNC machine. A computer numerical control machine automates various processes, improving the degree of accuracy compared to manual processes.
CNC machining allows for three-dimensional cutting using a single set of commands. Our CNC machines include three-axis, four-axis, and five-axis milling machines.
A five-axis milling machine allows for the milling of parts along the x, y, and z linear axes. The five-axis machines include two additional axes for milling from any direction. These machines are used to produce more complex shapes. With a five-axis machine, you also reduce cycle times by nearly one-third compared to a three-axis machine.
Screw Precision Machining
Screw machining is a process that was originally used to manufacture screws using a turret lathe. With improvements to the turret lathe, machinists were able to use the machine for a wider variety of processes.
The introduction of drum cams helped automate the machine’s movements. At The Federal Group USA, we utilize precision Swiss CNC lathes, multiple-spindle CAM automatics, and CNC multi-axis machining centers.
The desired cuts are entered into the CNC machine, which may utilize a variety of tools and processes. For example, a CNC machine may be used for turn machining using a lathe. The lathe is controlled by the computer, rotating the workpiece into a machine tool.
Swiss screw machines are automated machines with a guide bushing and a sliding headstock. The workpiece secures to the headstock and rotates with the spindle. Cutting tools move to trim the shape and diameter to the specifications of the part.
Multiple-spindle screw machines include multiple spindles to rotate several workpieces. These machines are often used for high-volume runs that require greater accuracy.
Benefits of Precision Machine Products
Precision machining involves multiple processes to complete a finished product. The designs often need to be entered into a CAD or CAM program. However, after programming the machine, the fabrication process is often more efficient compared to other fabrication methods.
Along with greater efficiency, machining provides many advantages:
- Reduces risk of human error
- Produces less material waste
- Provides greater consistency
- Creates more functional prototypes
Automating machining processes helps reduce the risk of human error. The commands are entered into the CNC machine, which controls the various lathes and milling machines.
Compared to manual machining, precision CNC machining reduces material waste. Precision machining involves the reduction of material, which does generate waste. However, CNC machines limit waste created by human error by the CNC machinist.
The automated processes provide greater consistency across parts. Each part should match the exact specifications of the blueprint, limiting the need for additional machining.
Precision machining may also provide a viable option for prototyping. With a CNC machine, you may produce functional prototypes.
With faster production cycles for large runs, this is a suitable solution for a variety of projects.
