CNC milling or turning fixtures are common in devices or workpieces that are used in manufacturing to resist large cutting forces, hold and position the piece, guide the tool when cutting, make sure operation goes smoothly, and produce continuous exchangeability and convenience in parts. Fixtures are mostly outlined of two constituents, one is fixed to the machine and immobile, and the other is a movable clamp or sometimes clamps. These fixtures for CNC machines are made of stainless, mild, and alloy steel materials that have various sizes and designs. Our main goal is to boost the economy.
The backbone of structured machining is the correct use and selection of CNC fixtures. Before deciding on the CNC clamp, we must acknowledge the features of mechanical filtering and the fixtures’ types. The mechanical production involves multiple varieties, small, single-piece batch, and less variety large batch. CNC fixtures exist in many types, and the main ones are Modular fixtures, hydraulic or pneumatic fixtures, or electromagnetic fixtures.
To begin with, a modular fixture contains a chain of machine tool components with a standard design with various sizes and purposes. You can gather many types of modern fixtures following the processing conditions that will save time for designing and constructing. This modular fixture will make the preparation and construction cycle shorter and enhance production efficiency. It is very convenient for small-batch products with complicated shapes because of its clamping compatibility, accurate positioning, and reusable characteristics.
Also, there’s a hydraulic/pneumatic fixture that is a work-holding tool that needs air or oil pressure as the source of power, and it uses its components to support, compress and locate the workpiece. The clamps of the hydraulic/pneumatic fixture can determine the workpiece position between the tool and cutters in a quick and precise way, making sure the machining and positioning are accurate.
Moreover, the clamping and positioning are fast, saving precious time. It also has a dense structure, available in automatic control, fast cutting, and multi-point clamping that is convenient for CNC machining centres with large processing scales.
Furthermore, the electromagnetic fixture has benefited from its multi-position clamping that’s easy to realise, quick, reliable, and stable clamping, multiple surface processing that saves a lot of energy, and automatic control. It is convenient for both small and large batch production.
