Ordinary countertop (fixture, T-slot countertop) T-slot table

Advantages: Made of high-quality aluminum profiles that are resistant to high temperatures, oxidation, and corrosion. They are mainly used for materials that are not easily adsorbed, hollow, thick or thin, and irregular materials. They are inexpensive, sturdy, durable, and have good fixing effects.

Disadvantages: Manual fixation, low efficiency, and limited processing area.

The T-shaped groove platform uses high-strength cast iron HT200-300 with a working surface hardness of HB170-240. After two manual treatments (manual annealing at 600-700 degrees and natural aging for 2-3 years), the working surface of the T-shaped groove platform adopts scraping technology. The working surface of the T-shaped groove platform can process V-shaped, T-shaped, U-shaped grooves, round holes, long holes, etc., which can be used to fix power machinery equipment. The use of this product has stable accuracy and good wear resistance. The working surface of the T-groove platform is processed with T-grooves, which are mainly used to fix workpieces. They are the basic working surface used by fitters to debug equipment, assemble equipment, and maintain equipment

Lathe fixture

Lathe fixture refers to a fixture used on a lathe to process the inner and outer rotating surfaces and end faces of workpieces. Most lathe fixtures are installed on the spindle; A few are installed on the bed saddle or bed body.

1. Centering lathe fixture: On the centering lathe fixture, the workpiece is often positioned with holes or outer circles, and the fixture adopts a centering clamping mechanism.

2. Angle iron lathe fixture: When machining the rotating end faces of parts such as shells, supports, levers, joints, etc. on the lathe, due to the complex shape of the parts, it is difficult to clamp them on a universal chuck, so a special fixture must be designed. This type of fixture is specifically shaped like an angle iron, so it is called an angle iron lathe fixture.

3. Flower disc lathe fixture: The fixture body of this type of fixture is called a flower disc, with several T-shaped grooves on it, and auxiliary components such as positioning elements, clamping elements, and indexing elements are installed. It can process the outer circle and inner hole of complex shaped workpieces. This type of fixture is asymmetrical and requires attention to balance.

Vacuum Table

Adopting PVC countertops with high cost-effectiveness, high hardness, high temperature resistance, corrosion resistance, small deformation, and no need for manual fixation of materials. Absorbing material automatically. More efficient than T-grooves, requires connection to a vacuum pump. The countertop is divided into multiple areas, and operators can switch from full processing to small processing. The area can be easily closed through the control valve in front of the machine.

Background: In the process of mechanical processing, it is often necessary to fix the processed object on the workbench for processing convenience. In order to fix the processed object on the machining table, fixtures are often installed on the workbench to fix the processed object. In some machining processes, setting fixtures can bring certain convenience to machining production, but in some machining processes, it can make the entire machining process more cumbersome, leading to low production efficiency.

With the continuous development of the woodworking industry, the demand for carving equipment in the woodworking market is also increasing. In some carving processes, the carved parts need to be fixed on the carving machine workbench. The existing woodworking processing equipment generally involves setting vacuum suction holes on the worktable, generating vacuum suction on the worktable to create negative pressure between the workpiece placed on the worktable and the worktable, thereby ensuring that the workpiece can be firmly fixed on the worktable. However, due to the unstable adsorption of workpieces on existing workbenches during actual use, they are prone to shaking during the processing, which cannot guarantee the quality of product processing and carving. Therefore, in view of this, it is particularly important to find a vacuum table structure that is simple in structure, stable and reliable in operation, and can generate stable adsorption force.

Regarding the selection of woodworking carving machine countertops (special case)

Firstly, in terms of material fixation: the woodworking carving machine for ordinary aluminum profiles uses fixtures to fix the material. After loading, technicians fix the four sides of the board with multiple fixtures, so that there will be no shaking during carving, resulting in carving errors. However, for woodworking carving machines with vacuum suction countertops, as long as the material is pushed onto the countertop, it is not necessary to worry about it. When cutting, only a gentle push is needed to cut the material. One major advantage of using a vacuum adsorption woodworking carving machine is its convenient loading and unloading, which saves time.

Secondly, in terms of price: as the cost increases, the price naturally becomes higher. The vacuum adsorption woodworking carving machine has an additional vacuum pump and a plywood table, and the spindle motor power has also increased, resulting in an increase of several thousand yuan in price. Of course, if you want to make wooden doors, cabinets, doors, and wardrobes, using a common table woodworking carving machine is definitely not feasible. You must choose a vacuum adsorption woodworking carving machine. Finally, in terms of power consumption: compared to woodworking engraving machines with aluminum profiles, it is obvious that vacuum adsorption engraving machines consume more power. Therefore, when considering style selection, everyone should also take this into consideration. The above three points are the main differences between these two models. If it is mainly used for hollowing and relief, and in a situation of tight economic strength, the editor recommends choosing a woodworking carving machine with a regular countertop. If it is mainly used for wooden doors, cabinet doors, and whole house customization, it is necessary to choose a woodworking carving machine with a vacuum adsorption countertop.
