German HIFLEX workholding fixtures HIFLEX model HIFLEX price

HIFLEX 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 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 machine tool's machining motion during processing. It typically consists of positioning elements, clamping devices, tool-setting and guiding elements or devices.

HIFLEX workholding fixture 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 equipment, such as in construction, paper industry, printing, glass, and other industries, to perform the task of holding and transporting thin and light items such as glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally speaking, using vacuum suction cups to grab 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 grabbing products with rough surfaces; 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. 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.

HIFLEX workholding fixture classification

1) General-purpose fixtures: General-purpose fixtures refer to fixtures that have been standardized and can be used within a certain range to process different workpieces. For example, three-jaw chucks and four-jaw independent chucks on lathes, vise jaws, indexing heads, and rotary tables on milling machines. These fixtures are generally produced by specialized factories and are often provided to users as machine tool accessories. Their characteristics are wide adaptability and low production efficiency, mainly suitable for single-piece and small-batch production. 2) Dedicated fixtures: Dedicated fixtures 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. 3) General-purpose adjustable fixtures and group fixtures: Their characteristic is that some components of the fixture can be replaced, and some devices can be adjusted to accommodate the processing of different parts. Fixtures used for group processing of similar parts are called group fixtures. Compared with group fixtures, general-purpose adjustable fixtures have less clearly defined processing objects and a wider scope of application. 4) Modular fixtures: Modular fixtures refer to fixtures assembled from a set of pre-manufactured standard elements and components according to the processing requirements of the part. Manufactured by professional manufacturers, their characteristics are flexibility, strong versatility, short manufacturing cycle, and reusability of components, making them particularly suitable for new product prototyping and single-piece small-batch production. 5) Pallet fixtures: Pallet fixtures are a type of fixture used on automated lines. This fixture not only serves to clamp the workpiece but also moves as an integral unit with the workpiece along the automated line from one station to the next for different operations.

HIFLEX workholding fixture selection

When selecting pneumatic grippers and jaw designs, these are the main factors to consider: 1) Part shape, orientation, and dimensional variations: If the object has two opposing flat surfaces, a double-jaw parallel gripper can be used, which resolves dimensional deviation issues. For cylindrical objects, double-jaw grippers can also be used for clamping. Note that containment or enveloping gripping requires less force. 2) Part weight: The gripping force must be sufficient to hold the object securely while performing the required operations. The type of jaw design must be considered when calculating the required gripping force. Please note that safety factors should be taken into account when selecting the required force, and air pressure is also a factor to consider. 3) Accessibility: This relates both to the operation being performed and the spatial requirements of the gripper jaws. If external operations are to be performed on the object, internal gripping is required. Scissor-style grippers are usually lower in cost but require more space for jaw movement. 4) Environment: Grippers used in harsh environments or cleanrooms require corresponding designs. 5) Object retention: When air pressure is no longer supplied, the gripper will release its hold on the object, causing it to drop. For such applications, spring-assisted grippers can be used.
