Grinding and Milling
E. Jordan Brookes is closely aligned with each of the leading manufacturers of plastic product. This provides our customers assurance that they will receive the highest quality product produced to the tightest tolerances available. When customers want something even better we turn to a grouping of local shops that specialize in tight tolerance grinding or milling. These companies offer specialized processes and capabilities honed over decades of experience.
Centerless grinding is a machining process that uses abrasive cutting to remove material from the outside diameter of a rod resulting in a cylindrical surface with a fine finish. The rod is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material is removed from the workpiece. This process resolves issues relating to ovality and results in extremely tight tolerance dimension control.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth. Double disk grinding abrades top and bottom surfaces simultaneously producing parallel surfaces with smoother surfaces and tighter dimensional control than can be achieved by extrusion or in some cases milling
Fly Cutting is a milling process using rotary cutters to remove outside surfaces of plastic plate providing the customer with a near net shape from which to manufacture their final product. It produces smoother surfaces and tighter tolerance dimension control than can be achieved by sawing.
