A method of making a longitudinal reinforcing structure for a wind turbine blade. The method comprises a) providing an elongate master strip (62) of reinforcing material having substantially flat first and second surfaces, the distance between the first and second surfaces defining the thickness of the master strip; and b) dividing the master strip transversely to form a first strip and a shorter master strip, the respective strips being arranged end to end such that a trailing end of the first strip is located adjacent a new leading end of the master strip. The step of dividing the master strip comprises removing material from a dividing region extending through the entire thickness of the master strip, wherein the dividing region is shaped such that a chamfer (19c) at the trailing end (19b) of the first strip is created and a chamfer (63a) at the new leading end (63) of the master strip is created when the master strip is divided.

A method for treating a surface of a rod of a piston, the rod being made of high mechanical strength alloy with a minimum hardness above 45 HRC, includes a grinding procedure, and a polishing procedure performed until a mean roughness Ra?0.2 ?m is obtained. This results in a surface finish allowing the dynamic sealing requirements of the piston to be maintained without requiring chrome plating.

The present disclosure provides a method of detecting and preventing grind burn from developing on a gear. The method includes performing acoustic emission testing while the gear is being ground during a grinding operation. The grinding wheel is evaluated during an eddy current test to detect material buildup on the grinding wheel which could cause grind burn. In addition, the method includes collecting swarf from the gear during the grinding operation and inspecting the swarf for an indication of grind burn.

Described is a method for grinding workpieces, which comprise at least one cylindrical and profiled portion each, on one and the same grinding machine. The workpiece is ground initially in a first grinding operation in a first clamping in the grinding machine, said first grinding operation being followed by a second grinding operation once the first clamping has been released and then, before the start of the second grinding operation, a second clamping has been generated.

A device for grinding pre-milled and hard metal-tipped teeth of saw bands, is provided. The device comprises a feed device for feeding a temporarily formed workpiece in a timed manner, wherein the temporarily formed workpiece is formed from a plurality of saw bands which are parallel to one another. The device further comprises a clamping device which clamps the plurality of saw bands against one another, and a grinding unit for simultaneously grinding a plurality of teeth. The grinding unit comprises a grinding wheel with a plurality of grinding profiles. A corresponding method is also provided, where the grinding unit grinds both the tooth backs and the tooth faces to final dimension in exactly one linear movement.

The present invention relates to a composite wheel deburring device, which is composed of a stand, servo motors, guide rails, a first brush system, a second brush system, and a synchronous clamping rotary system. During use, the first servo motor drives first brush to rotate, and a second servo motor drives a second brush to rotate; the second brush starts to remove rim corner burrs at flanges of the wheel; right servo electric cylinder enables the first brush to move to an appropriate position, and jacking cylinder enables the first brush to perpendicularly come in contact with window rim corners at the roots of the flanges by a second guide rail, so that rim corner burrs at the position can be well removed; and upper servo electric cylinder adjusts the angle of the second brush to an appropriate angle, so that rim corner burrs of wheel rims are removed.
