Micromachining uses traditional material removal processes combined with state of the art milling and turning technologies, thus resulting in extremely small parts. Micromachining technologies can work with a variety of materials. Metals are most commonly used for micro precision parts, with typical part features of less than 1mm!
Micromachining Case Study
- Material: Pt/w (92/8)
- Units: Inches
Micro-Turning & Micro-Milling
Micromachining works generally the same as traditional machining, but does this at an extremely small scale. Micro-turning removes material from a part by rotating about an axis, and thus makes micro cut out features that are symmetric about that axis. Micro-milling is a process that moves material into a rotary cutting bit, hence creating cut out features by material removal. Multi-axis micromachining allows for cutting of extremely precise features about multiple axes, and as a result can produce parts with extremely small and complex geometries. Surface finishes are typically as machined (0.80 Ra µm), however can be precision polished upon specification. We provide material certification and certification of compliance upon request.
Micro-EDM & Femtosecond Laser
Micro EDM (Electrical Discharge Machining) works by using electrical discharges to remove material from a substrate. Due to its the use of tiny electrical discharges by custom made electrode, this process is used to create intricate shapes and features on conductive materials, such as sharp inside corners. Femtosecond laser machining goes beyond Micro EDM in terms of micro machining features and capabilities. This technology uses ultra fast laser beams to machine away material with resolution on the scale of 10µm and smaller. This technology is hence used for the most intricate of features.
Micro Scale Dimensions and Tolerances
We hold micromachined tolerances as low as ± .0001″, with typical part tolerances of ± .0005″. We specialize in parts that are extremely small, and hence are able to best serve customers with part features on a scale of under .010″, and as small as .001″.
Micromachined parts can be made from a variety of metals and plastics, such as:
300 series stainless steel is a common material of choice. For less common material, you may also choose to source your own bar stock of material for machining. Bar stock is ideally 1mm in diameter, with a minimum 500mm in length, and must additionally be very straight in order for proper machining.
