Quality Commitment; Our double disk grinding wheels deliver outstanding life, which optimizes grinding time cycles and provides consistency over the 网页Double disc grinders are a fine grinding process and can achieve extremely close tolerances, often similar to what 网页Double-Disc Grinding is a highly efficient grinding method that reduces pre-machining costs up to 50% and provides dimensional tolerances, parallelism, and flatness up to ±.001″. 网页What is Double Disc Grinding? Double-disc grinding is an extremely efficient grinding process that uses abrasive wheels that oppose one another, grinding and removing equal amounts of stock from both sides of a blank. The result is a flat aluminum or stainless steel machine-ready blank with parallel tolerances to .0005” and finishes to 16 Ra 网页Double Disk Grinding. Double disk grinding is a fast, economical finishing process. Work parts are passed quickly through two rotating vertical abrasive wheels which can remove a large amount of material. Grinding is frequently used as part of a two-step process. Parts first go through a grinding process to quickly achieve approximate tolerances. 网页2020年6月14日 For example, double disk grinding can achieve surface finishes of up 16 Ra µin (0.41 µm) on aluminum and up to Ra 8 µin (0.20 µm) on ferrous alloys. 网页2022年1月1日 Double-disc (DD) grinding is a high-productivity, high-accuracy process used widely in the automotive, bearing, tooling and semiconductor industries for creating parallel surfaces on two opposing flat faces [1]. Although over 100 years old, very little fundamental analysis existed on DD grinding until the 1990s. 网页2023年3月4日 Work pieces are machined on the double-disc grinding machine using a through-feed, plunge-cut or oscillation process, depending on the respective 网页2023年3月4日 The latest generation of the Planet V machine series takes double sided grinding, also known as Double Disk Grinding, to a new level. The extremely rigid machine bed enables grinding of steel, sintered metal, non-ferrous metal, , ceramics and glass. Two powerful motors achieve stock removal of over 1mm at cycle times well below 网页Double-Disc Grinding is a highly efficient grinding method that reduces pre-machining costs up to 50% and provides dimensional tolerances, parallelism, and flatness up to ±.001″. (For even tighter tolerances, see our Surface Grinding process.) Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind two sides of the 网页2023年3月4日 Double disc grinding is a highly efficient grinding method that reduces pre-machining costs up to 50% and provides dimensional tolerances to ±.0002″, 网页Double Disk Grinding. Double disk grinding is a fast, economical finishing process. Work parts are passed quickly through two rotating vertical abrasive wheels which can remove a large amount of material. Grinding is frequently used as part of a two-step process. Parts first go through a grinding process to quickly achieve approximate tolerances. 网页What is Double Disc Grinding?

Double-Disc Grinding is a highly efficient grinding method 网页A vertical double-disk grinding machine is a grinding machine in which two grinding wheel shafts face each other vertically.There are a variety of machining patterns, from 网页2020年9月24日 Our service portfolio ensures that your double disc grinding solution benefits from a consistently high level of production quality and minimized downtime. Services range from consulting, sample part processing, and process development to operator training, repairs and inspections. Our 24/7 hotline and our service offices in 网页1995年12月1日 For example, a horizontal double-disc grinder can process a typical 6-inch connecting rod at a production rate of 1200 per hour, while a vertical configuration will be limited to approximately 300. On the other hand, vertical double-disc grinders often require less floor space and typically offer broader flexibility--for example, for changeover 网页2023年3月4日 Work pieces are machined on the double-disc grinding machine using a through-feed, plunge-cut or oscillation process, depending on the respective 网页2020年9月24日 Our service portfolio ensures that your double disc grinding solution benefits from a consistently high level of production quality and minimized downtime.

Our 24/7 hotline and our service offices in 网页2003年6月5日 Fig. 3 illustrates the surface grinding process. Grinding wheels are diamond cup wheels. The workpiece (wafer) is held on a porous ceramic chuck by mean of vacuum. The axis rotation for the grinding wheel is offset a distance of the radius relative to the axis of rotation for wafer. During grinding, the grinding wheel and wafer rotate 网页A vertical double-disk grinding machine is a grinding machine in which two grinding wheel shafts face each other vertically.There are a variety of machining patterns, from 网页2019年5月22日 Double or Dual Disc Grinding is a highly efficient method of removing equal stock from opposing faces of a part, normally symmetrical stock removal. The 网页Double-Disc Grinding. Grinding two sides of the part at the same time reduces costs by 50% and produces superior dimensional tolerances, parallelism and flatness to +/ 网页Double Disk Grinding. Double disk grinding is a fast, economical finishing process. Work parts are passed quickly through two rotating vertical abrasive wheels which can remove a large amount of material. Grinding is frequently used as part of a two-step process. Parts first go through a grinding process to quickly achieve approximate tolerances. 网页Thru-Feed Grinding is a production flat machining process that does almost everything a conventional double disc or vertical spindle grinder can do. Thru-feed grinding is the most efficient method known for high production surface grinding of small to mid size parts because it practically eliminates non-productive time. 网页Metal grinding is a key step in the process of many welding and fabricating operations, but oftentimes operators don’t receive proper training in grinding best practices or troubleshooting. Problems in the grinding operation can result in costly downtime, potentially holding up project timelines or slowing the movement of parts out the door.
