1. What is CNC milling and turning?
CNC milling and turning are subtractive manufacturing technologies that use cutting tools programmed to remove material from solid blocks. The difference is that the workpiece remains stationary in milling operations, whereas it's in rotation in turning operations.
2. What is tool offset in CNC milling?
Tool offset refers to the allowance made by a milling machine to design the cutting tool and shift its position. It ensures the CNC machine is operating on the right part of the workpiece.
3. How does CNC milling work?
CNC milling is the process of removing materials from metal, plastic, or ceramics with a rotating cutting tool. Our 3-axis, 4-axis, and 5-axis processes allow for high-precision machining at high speed.
4. What can you make with a CNC milling machine?
If you can design it, you can mill it. CNC milling can be used to create any shape, no matter how complex the geometries.
5. What is electrical discharge machining?
Electrical discharge machining, or EDM, is a subtractive process where the material is removed using thermal energy and is excellent for machining hard materials like titanium and complex geometries.
6. What does FDM stand for?
FDM stands for Fused Deposition Modeling, also referred to as Fused Filament Fabrication (FFF), and is the most common type of 3D printing.
7. What is FDM 3D printing?
FDM 3D printing is an additive manufacturing technique that fuses layers of materials in a pattern to create the desired model. A plastic filament is melted and deposited in layers on the print bed.
8. What is ISO 13485?
ISO 13485 specifies the quality management system requirements a manufacturing entity needs to demonstrate to prove its ability to provide safe and compliant medical devices.
9. What does it mean to be ISO 13485 certified?
An ISO 13485 contract manufacturer has ensured that their QMS processes meet the legal and regulatory requirements for medical devices.
10. What is laser sintering?
Selective laser sintering (SLS) is a method of additive manufacturing that uses a CO2 laser to sinter thermoplastic powder into a solid structure based on a 3D model.
11. What is a Swiss screw machine?
A Swiss screw machine is an automatic lather that allows for high volume production with more accuracy and less downtime.
12. What is a punch press machine?
A punch press is a CNC-controlled machine used to cut holes in material by applying pressure to a die in which a workpiece is held.
13. How expensive is injection molding?
Injection molds can cost anywhere between $1000 for simple, single cavity, low-volume plastic molds to $80,000+ for complex, multi-cavity, high-volume steel molds. But these costs are distributed among hundreds of thousands of parts, making injection molding affordable.
14. What causes flow lines in injection molding?
Flow lines are defects caused by variations in the cooling speed of the plastic as it moves through the mold. But, they are easily prevented by making adjustments to the injection molding process.
15. Can you injection mold EPDM?
Yes, EDPM can be injection molded by feeding the rubber material into a heated barrel and forcing it into a mold cavity for curing and hardening.
16. How does plastic injection molding work?
The molding machine heats the pastic until it liquefies, at which point it’s injected under pressure into a closed metal mold tool, where it cools and hardens into shape.
17. What is a CNC Machine?
CNC are machine tools that use Computer Numerical Control programming to cut or move metal. A CNC machine can refer to a range of complex machinery that includes mills, lathes, grinders, and routers.
18. What does a CNC machine do?
A CNC machine takes raw materials and shapes them into desired specifications through cutting, grinding, drilling, turning, or milling. A CNC machine removes material from a workpiece through the actions of its cutting tools.
19. How does a CNC machine work?
CNC machines are operated via computerized numerical control. Desired cuts are programmed into the machine, which cuts out the dimensional tasks to achieve the desired shape.
20. What does a CNC turner do?
A CNC turner is responsible for the manufacturing of precision parts to desired specifications through CNC milling and turning. Some of their responsibilities include monitoring machining processes, inspecting finished products, and leading test runs.
21. What is a CNC Mill operator?
A CNC mill operator is a machining professional responsible for setting up, operating, and tending to CNC milling machines. Part of their role includes positioning and securing workpieces on machines, observing milling machine operation, adjusting controls, and selecting cutting speed feed rates.
22. What is a CNC milling machine?
A CNC milling machine utilizes computerized controls to progressively remove material from workpieces to produce a custom-designed component. CNC milling machines are used to produce high accuracy, high tolerance custom parts.
