A scarfing machine includes a base and a pair of platens adjustably positioned on the base. The pair of platens are configured as an upper platen and a lower platen such that the upper platen is fixed to the base and the lower platen is adjustably positioned on the base, to receive and support a member for scarfing. Also, at least one platen of the pair of platens is hollow and is defined with an inlet port and an outlet port. The scarfing machine further includes a scarfing tool, extending from either side and along a length of at least one of the pair of platens, to scarf the member supported between the pair of platens. The scarfing machine also includes a cooling circuit, fluidly connectable to the inlet port and the outlet port of the at least one platen of the pair of platens.

This disclosure relates to a belt grinder includes frame and first grinding assembly. The first grinding assembly includes transmission roller set, grinding belt and adjusting assembly. The transmission roller set includes driving roller and driven roller. Both the driving roller and the driven roller are rotatably disposed on the frame. The grinding belt is installed over the driving roller and the driven roller. The adjusting assembly includes rotatable component and contact rollers. The rotatable component is rotatably disposed on the frame. Rotation axis of the rotatable component is parallel to rotation axis of the driving roller. The contact rollers are rotatably disposed on the rotatable component. Contact rollers are different in shape. The rotatable component is rotatable with respect to the frame so as to force one of the contact rollers to contact or to be separated from the grinding belt.

A grinding or sanding machine for grinding or sanding a surface of a workpiece includes a transportation device for transporting a work piece, a revolving grinding or sanding belt, and at least one pressure beam for exerting a pressure toward the transportation device. A plate is provided that is movable in a plane perpendicular to the direction in which pressure is exerted. The plate is disposed between the belt and the pressure beam. A drive device randomly moves the plate in plate movement directions in terms of either or both direction and speed.

A flexible display production apparatus of the present disclosure includes: a stage (520) for supporting a flexible display supporting substrate (10), the flexible display supporting substrate including a glass base (11) and a synthetic resin film (12) provided on the glass base; a polisher head (535) configured to approach a selected region of a surface (12s) of the synthetic resin film (12) and polish the region so that a polish recess (12c) is formed in the surface (12s); and a repair head (536) for supplying a liquid material (20a) to the polish recess (12c) formed in the surface (12s) of the synthetic resin film (12) and heating the liquid material (20a), thereby forming a sintered layer (20) from the liquid material (20a).

The invention relates to a method for producing a gear worm (12) which is located in particular on an armature shaft (14) of an electromotive drive unit (10), wherein firstly a worm gear (20) having screw flanks (22) axially opposite one another on a longitudinal axis (18) is formed by means of a rolling tool, and subsequently a groove structure (24) which is concentric about the longitudinal axis (18) is formed on the screw flanks (22) by means of an additional process step. The invention also relates to a gear worm (12) produced according to the method according to the invention, and to a transmission drive unit (10) containing such a gear worm (12).

The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

The polishing apparatus has a polishing unit capable of polishing a peripheral portion of the substrate to form a right-angled cross section. The polishing apparatus includes: a substrate holder that holds and rotates the substrate; guide rollers that support a polishing tape; and a polishing head having a pressing member that presses an edge of the polishing tape against the peripheral portion of the substrate from above. The guide rollers are arranged such that the polishing tape extends parallel to a tangential direction of the substrate and a polishing surface of the polishing tape is parallel to a surface of the substrate. The substrate holder includes: a holding stage that holds the substrate; and a supporting stage that supports a lower surface of the peripheral portion of the substrate in its entirety. The supporting stage rotates in unison with the holding stage.

A flexible display production apparatus of the present disclosure includes: a stage (520) for supporting a flexible display supporting substrate (10), the flexible display supporting substrate including a glass base (11) and a synthetic resin film (12) provided on the glass base; a polisher head (535) configured to approach a selected region of a surface (12s) of the synthetic resin film (12) and polish the region so that a polish recess (12c) is formed in the surface (12s); and a repair head (536) for supplying a liquid material (20a) to the polish recess (12c) formed in the surface (12s) of the synthetic resin film (12) and heating the liquid material (20a), thereby forming a sintered layer (20) from the liquid material (20a).

A wheel grinding device consists of a lower lifting rotary system, spoke grinding units, a center hole grinding system and an upper lifting and clamping rotary system. The wheel grinding device not only can be used for grinding the center hole of a wheel of any size, but also can be used for grinding the back of wheel spokes of different sizes and shapes via the actions of brush belts.
