German Chiaravalli workholding Chiaravalli model Chiaravalli price

Chiaravalli workholding is an electromagnetic fixture that secures the workpiece being machined by means of the suction force generated by the chuck body when the electromagnetic coil is energized. An electromagnetic chuck consists of several parts, including a core, coil, faceplate, and bracket. The electromagnet, formed by the coil and core together, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Electromagnetic chucks were initially used on grinding machines to replace clamping plates and bolts for securing workpieces to be ground; such electromagnetic chucks are relatively simple and can only secure flat plate-type workpieces. This is the traditional electromagnetic chuck, and its application has significant limitations. With industrial development, enterprise demand for electromagnetic tools has grown increasingly large, and the requirements put forward have become higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

Chiaravalli workholding introduction

Vacuum suction cups are one of the actuators for vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices, such as in construction, papermaking, printing, glass, and other industries, to perform tasks of holding and transporting thin and light items such as glass and paper. Vacuum suction cups are also known as vacuum lifting fixtures and vacuum suction nozzles. Generally speaking, using vacuum suction cups to grab products is one of the most inexpensive methods. There is a wide variety of vacuum suction cups; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grabbing products with rough surfaces, and polyurethane suction cups are very durable. In addition, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing the suction cup. Usually, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

Chiaravalli workholding applications

Fixtures are process devices used to quickly fasten workpieces during machining, maintaining the correct relative positions of the machine tool, cutting tool, and workpiece. In other words, Workholding tooling fixtures are indispensable components in mechanical machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent, and environmentally friendly directions, fixture technology is moving towards high precision, high efficiency, modularity, combination, universality, and economy. Fixtures are also called clamps. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces in any operation of the process can be called a fixture. Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures. Among these, machine tool fixtures are the most common and are often simply referred to as fixtures. When machining workpieces on a machine tool, in order for the workpiece surface to meet technical requirements specified in drawings, such as dimensions, geometric shape, and mutual positional accuracy with other surfaces, the workpiece must be properly located (positioned) and firmly clamped (clamped) before machining. The application of machine tool fixtures helps ensure machining accuracy of the workpiece and stabilize product quality; helps improve labor productivity and reduce costs; helps improve workers' labor conditions and ensure safe production; and helps expand the process range of machine tools, achieving "multi-purpose use of one machine". Fixtures usually consist of locating elements (to determine the correct position of the workpiece in the fixture), clamping devices, tool-setting guide elements (to determine the relative position of the tool and workpiece or guide the tool direction), indexing devices (to allow the workpiece to complete machining at several stations in one installation, including rotary indexing devices and linear motion indexing devices), connecting elements, and the fixture body (fixture base). Fixtures are also used extensively by electronics manufacturers. In production, to improve production efficiency and product quality, tooling fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (capable of assembling fixed shapes and heights, etc.). Their actual use in electronic manufacturing plants is very broad; because they are non-standard custom-made, the possibilities are limited only by imagination.

Chiaravalli workholding maintenance

1) Before use, check whether the limit dimensions remain in the correct position. 2) If stop pins are worn beyond tolerance, they can be repaired by grinding; if baffles, pins, or locating taper pins are worn beyond tolerance, they can be reassembled, offsetting the worn areas for continued use. 3) After use, anti-rust oil must be applied. Regular long-term lubrication maintains the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and seizing, so correct lubrication is essential. After machining, be sure to clean the synchronous fixture body and slide ways with an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while opening the main jaws to their widest position, to easily clean accumulated chips inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new parts immediately if severe. Lubricate thoroughly before assembly.
