kako fixtures, German kako models, kako prices

kako 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 a 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 because it can no longer be used. 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 correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices, etc.

kako Fixture Introduction

Vacuum suction cups are one type of actuator 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 equipment, such as in construction, paper industry, printing, glass, and other industries, to perform tasks of holding and transporting thin and light items like glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally speaking, using vacuum suction cups to grasp products is the most economical method. 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 grasping products with rough surfaces; polyurethane suction cups are highly 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. Typically, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

kako Fixture Structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. According to the motion of the fingers, they can be divided into translational and rotational types. According to the mechanical clamping method, they can be divided into external clamping and internal expansion types. According to the mechanical structural characteristics, they can be classified as electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps the workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is completely released during movement, dwelling, and loading processes. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

kako Fixture Maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerances, it can be repaired by grinding; if the baffle, pin, or positioning tapered pin wear exceeds tolerances, they can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication maintains the life of synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so proper lubrication is essential. After machining, be sure to clean the body and slide ways of the synchronous fixture 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 a thorough cleaning (at least every two months when machining cast iron or copper parts). Check parts for damage or wear, and replace with new ones immediately if severe. Lubricate thoroughly before assembly.
