CNC Machining




Amfas offers a wide range of CNC machining capabilities. The precision and accuracy of any machining is a function of the equipment, fixturing, cutting tools, and of course skilled machinists. Amfas’ use of the best people and equipment for the job at hand allows for tight tolerances in any production part that we fabricate.

Milling

CNC milling is a process in which the cutting tool rotates and moves into the workpiece to remove the desired material. Milling is categorized into vertical and horizontal orientations, as well as the number of axes of motion. Amfas has a wide range of milling capabilities to suit your exact need. 

  • 3-,4-, and 5-axis capabilities 
  • Extensive material selection of plastics and metals
  • Rapid Prototyping to high-volume manufacturing

Turning

Amfas can accommodate almost any size and type of turning application. Most work fits within a 50mm (2 inch) diameter capability.  Larger diameters typically move to chuck type lathes or short-bar automatic machines.  


Swiss screw machining is a specialty at Amfas. Modern screw machines under 25mm typically use swiss type cutting and holding methods.  This method was developed many years ago by Swiss machinery builders which allows the bar stock to move in/out of the cutting area using a sliding headstock.  The headstock is the collet that supports the bar material.  The cutting of material is done immediately at the collet support to minimize the flex of the bar material.  This allows long thin parts to be cut with great precision.  Amfas uses the latest machine and tooling technology to provide cost effective screw machine parts.

Electrical Discharge Machining (EDM) 

EDM also known as die sinking or wire burning is a process in which metal is removed from the workpiece by electrical discharges between two electrodes, separated by dielectric fluid. Imagine an electrically charged hair thin wire that will melt away tiny particles of metal. Wire EDM processing can hold incredibly tight tolerances, create complex and intricate shapes, work with extremely hard or soft materials, and make tiny parts. Advantages of EDM are: 

  • Can hold incredibly tight tolerances
  • Create complex and intricate shapes that would otherwise be impossible with conventional machining 
  • Work with extremely hard or soft materials 
  • Very good surface finish may be obtained
  • Extremely hole small holes are possible
