high-density fiberboard (HDF) uses wood-based raw materials, particularly softwood, hardwood, and mixtures of different wood species. However, expected wood shortages, forestry regulations, and the presumed lower cost of non-wood materials have prompted MDF and panel-board producers worldwide to explore alternative sources of lignocellulosic fibers.

Get PriceSFM is a combination of diameter and the velocity (RPM) of the material measured in feet-per-minute as the spindle of a milling machine. The faster the spindle turns, and/or the smaller the diameter, the higher the SFM. The goal is to tool a job to run the SFM as high as possible to increase hourly part production.
Get PriceMaterial Smear and Its Removal Material smearing can have a very detrimental effect on an LPI inspection as defects that are normally open to the surface can be partially or completely covered over. Some of the processes that can cause material to smear include machining, honing, lapping, sanding, scraping, grit blasting, tumble de burring, and preening operations.
Get PriceThis effects the homogenization of the melt. It should not be set too high, owing to the shear sensitivity of the material. Injection Speed The correct injection speed is dependent on gating, wall section and flow. It should be kept as low as possible.

Get PriceUnlike milling in most other materials, coolant is always recommended to assist in chip removal, to control heat at the cutting edge and to prevent the re-cutting of chips. High-pressure coolant (70 bar (1,015 psi)) applied through the spindle/tools is always to be preferred instead of
Get PriceMaterials which machine with high shear zone angles tend to minimize built-up edge effects. These include the aluminum alloys, cold worked steels, free-machining steels, brass and titanium alloys. If surface finish alone were the chosen index of machinability, these latter metals would rate higher than those in the first group.
