Raptor work holding 5-axis fixtures have a dovetail design which quickly locks the part in place eliminating traditional clamps and vices and providing CNC access to all five faces of the material. Raptor 5-axis Fixtures are available to buy in several sizes for any machining or milling application.
Oct 25, 2014· Principle of the Surface grinding machine • Surface grinding is used to produce a smooth finish on flat surface. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles cuts chips of metallic or non-metallic substance from a work piece, making a face of it flat or smooth.
The work holding devices are used to hold and rotate the workpieces along with the spindle. Different work holding devices are used according to the shape, length, diameter and weight of the workpiece and the location of turning on the work.
Surface grinding is a finishing process that smooths the surface of metallic or nonmetallic materials and gives them a more refined look. The surface grinder is comprised of an abrasive wheel, a work-holding device known as a chuck, and a reciprocating table.
Tools Primarily Used in Grinding Vises / Sine Plates / Magnetic Squaring Blocks / Wheel Dressers / Magnetic & Mechanical Chucks. Also used in grinding yet found under other areas of use are: spin & indexing units, v-blocks, 5C collet chucks, dovetail fixtures, expanding collet pins, magnetic chucks, mechanical chucks, and surface gauges.
Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces.
The tolerances that are normally achieved with grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.
A work-holding device for use with grinding machines having a grinding Wheel and a base with a post in parallel relation to the axis of the wheel, a base bracket, means for adjustably clamping the base bracket on said post for adjustment at its free end toward and from the grinding wheel, a supporting bracket pivotally mounted upon the free end ...

Apr 18, 2013· Surface Grinding Work Holding Question ... My CNC grinding experience was limited to work held in collects and chucking devices so I am not referring to use my finger rule for CNC magnetic application but with a good program and with feeds set low it should work there also.
Apr 19, 2013· Still another work holding device I used was a lay down short flat thin bar that had raised rails of 1/16 and 1/16 x .020 deep undercuts along the length. I would lay it flat on the chuck and skim off just a few tenths and then a very close job would set on the bar rails rather then directly on the chuck.
Aug 16, 2011· One of the most established and yet least understood methods of cylindrical workholding is in the centerless grinding process. Primarily known for its use grinding stock into precise rounds, centerless grinding is accomplished by feeding stock between a fixed guide blade and rotating regulating roller and a rotating grinding wheel.
• Magnetic workholding systems give continuous 5 face machining – no need to stop and re-position • Magnetic chucks give excellent access for through machining, cutting and drilling • Improved safety – failsafe magnetic technology guarantees a secure hold
Dec 03, 2016· Work-Holding Devices • Work must be held in vise, held on V-blocks or bolted directly to table for some surface- grinding operations • Most of ferrous work ground on surface grinder held on magnetic chuck – Clamped to table of grinder 25.
Workholding devices — Almost any workholding device used on a milling machine or drill press can be used on surface grinders. However, the most common workholding device on surface grinders is a magnetic chuck. Cylindrical grinding Cylindrical grinding is the process of grinding .
