The present invention relates to the technical field of material processing and provides a method for making a metal material composite, including: contacting a first surface of a first plate with a second surface of a second plate; placing the first plate and the second plate in a recess in a circumferential direction of a first roller such that a third surface of the second plate contacts a bottom wall of the recess in a circumferential, the third surface being opposite the second surface, the first plate having a greater hardness than the second plate; and controlling a first roller and a second roller to rotate, thereby rolling to combine the first plate and the second plate into a composite plate, where a fourth surface of the first plate contacts a surface of the second roller and the fourth surface is opposite the first surface during the rolling. According to the method for making a metal material composite in the present invention, flashings and burr on the side edges of a composite plate are avoided by placing the first plate and the second plate in a recess for machining.

A cell phone frame, and a method for manufacturing the same, includes a composite plate. The composite plate encloses an accommodation space for accommodating the cell phone. The composite plate includes a first plate and a second plate, a first side surface of the first plate having striations. The first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations.

The present invention concerns methods and apparatus for spreading beads in a tire. Particular embodiments of such methods include securing at least a portion of a first bead of the tire and positioning a tire spreader within the central opening of the tire, the tire spreader having a bead engaging portion for engaging a portion of a second bead generally opposite the secured portion of the first bead. Such methods may further include automatically translating the bead engaging portion of the tire spreader generally in an axial direction of the tire to displace the engaged portion of the second bead a desired distance to increase the distance between the opposing beads to form a widened interior cavity opening.

A double-station wheel burr removing device is provided, comprising clamping drive systems, lifting drive systems, a left burr brushing system, a right burr brushing system, a rotary switching system and the like. The double-station wheel burr removing device in use can simultaneously remove burrs on two wheels having different heights and different diameters at the end face of the upper rim, the valve hole, the lateral cutting position of the upper rim and the riser, so the production efficiency is very high; and simultaneously, the device has the characteristics of high automation degree, advanced process, strong generality, safety and stability.

An apparatus (100) for cutting workpieces comprises a clamping mechanism (2) adapted to be fastened to said workpiece (1) rotatably therearound. The clamping mechanism (2) comprises a frame element (5) and first and second arms (6, 7) extending therefrom. The arms (6, 7) are coupled at one end to the frame element (5) of the clamping mechanism (2) and each arm (6, 7) has its free end fitted with a contacting member (15, 16, 31, 32) configured to contact the surface of the workpiece. The apparatus comprises also two movable guiding members (28, 29) to which said arms (6, 7) are coupled so that when said guiding members (28, 29) are moved away from each other, the contacting member (15, 16, 31, 32) of the arms (6, 7) are configured to be moved away from each other and vice versa. The apparatus comprises also at least two supporting bars (50, 51) elongated through said guiding members (28, 29). The first supporting bar (50) comprises a first threaded portion (52) with a first coupling means (21), and the second supporting bar (51) comprising a second threaded portion (53) with a second coupling means (22). The first arm (6) and the first coupling means (21) are functionally coupled to each other by a first suspension arm (24), and the second arm (7) and the second coupling means (22) are functionally coupled to each other by a second suspension arm (25). The supporting bars are configured to be rotated at the same time.

The present invention discloses a device (100) for abrading or removing material from a joint or groove by means of at least one abrasive area (30) provided at a rib (20) associated with a main body (10).

A system for removing material from a workpiece comprising: a mounted-point grinding tool configured to move from a first position to a second position traversing at least a portion of a slot in a workpiece and removing material from a surface of the workpiece; and a first nozzle configured to deliver coolant to the mounted-point grinding tool, wherein the first nozzle is configured to move with the mounted point grinding tool from the first position to the second position so that the distance between the first nozzle and the mounted-point grinding tool remains substantially unchanged. A second nozzle can be mounted on the opposite side of tool from first nozzle, with the second nozzle also configured to move with the grinding tool so that the distance between the first nozzle and the mounted-point grinding tool remains substantially unchanged during grinding.

Systems and methods for conditioning blades are provided. A method may include, for example, obtaining a cutting device, measuring various characteristics of the cutting edge of the cutting device, creating a current edge profile based on the characteristics, creating a modified edge profile, and/or conditioning the blade. Conditioning may include grinding, buffing and/or polishing. One or more of the conditioning steps may be based on the modified edge profile.
