German maw workholding fixtures maw model maw price

maw workholding fixtures are devices used on machine tools to clamp workpieces and guide cutting tools. They refer to fixtures specifically designed for a particular operation on a specific workpiece. Their characteristics include compact structure, rapid, convenient, and labor-saving operation, ensuring high machining accuracy and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes obsolete and is scrapped due to inability to reuse. It is only suitable for production with fixed products and large batch sizes. It contacts the positioning datum of the workpiece to determine the correct position of the workpiece in the fixture, thereby ensuring the relative correct position between the workpiece and the cutting tool and machine tool motion during machining. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

maw workholding fixture requirements

Whether gripper-type or suction-type, the robot end-effector must also meet the repeatability accuracy required for the task. The structure of the robot end-effector should be as simple and compact as possible, with light weight, to reduce the load on the arm. Dedicated rather than general-purpose robot end-effectors have simpler structures but high work efficiency, and can perform various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structure and high cost. Therefore, it is advocated to design and use serialized and standardized dedicated robot end-effectors that can be quickly replaced. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation problems. For cylindrical objects, double-jaw grippers can also be used for clamping. Note that containment or enveloping gripping requires less force.

maw workholding fixture applications

Fixtures are process devices used to rapidly secure workpieces during machining, maintaining the correct relative positions among 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 jigs. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces in any process step 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, often simply referred to as fixtures. When machining workpieces on machine tools, to ensure that the surface of the workpiece meets technical requirements such as dimensions, geometric shape, and mutual positional accuracy with other surfaces as specified in the drawings, the workpiece must be properly positioned (located) and firmly 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 working conditions for workers and ensure safe production; helps expand the process range of machine tools, achieving "multi-purpose use of one machine". Fixtures typically consist of positioning elements (to determine the correct position of the workpiece in the fixture), clamping devices, tool-setting and guiding elements (to determine the relative position between the tool and workpiece or guide the tool direction), indexing devices (allowing the workpiece to complete machining at several stations in one installation, including rotary indexing devices and linear movement indexing devices), connecting elements, and fixture bodies (fixture bases), etc. The use of fixtures in electronics manufacturers is also very high. 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.). The actual applications in electronic manufacturing plants are very extensive. Since they are non-standard custom-made, the possibilities are limited only by imagination.

maw workholding fixture selection and usage

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters; among the performance parameters, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of the load allowed to be lifted under specified operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with an electromagnetic chuck, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, T-shaped screws can be screwed in for lifting. They are fixed to the workbench using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then perform a precision grind on the upper surface of the chuck to ensure the parallelism between the upper surface and the bottom surface. When holding workpieces, sufficient positioning holding force can be obtained by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons.
