The equipment for sawing acrylics is quite different from ordinary woodworking saws.
Nowadays, the small-scale enterprises in the acrylic industry generally use laser cutting to carry out the material. The larger ones use woodworking equipment to carry out the material. In fact, there are still many misunderstandings.
Acrylic sheets, PS sheets, all have similar physical properties. There are also differences in melting point and hardness. The tool should also use different mechanical indexes during the cutting process. In selecting the tool and tool speed, cutting speed All should be changed. In addition to the use of special saw blades, the speed of the saw blade must also be adjusted to adapt to different materials, different thicknesses of different melting points and the sharpness of the saw blade. If these contradictions cannot be solved, the problem of the sol will inevitably occur frequently. The saw blade is stuck and the equipment is damaged, resulting in unnecessary waste of the product. However, the reciprocating saws in the woodworking industry are mostly on the market. Even the highly automated electronic cutting saws rarely meet the requirements, and the problems are inevitable.
Everyone noticed that many electronic cutting saws and blanking devices have gaps on the table to avoid mechanical grippers. However, this design has a fatal problem when sawing acrylic type materials, because the position of the gap cannot be processed. The product produces a perfect compacting effect. After machining, the opposite workpieces in the pressing device and the notch of the table will have a rough cross-section, the crevice and the film are detached, and the effect of the thin plate is particularly poor. These conditions are relatively low in industries requiring less The lighting industry problem is not very prominent, but it is unacceptable if it is a light guide plate and a diffuser plate. Therefore, internationally, as early as Japan’s later Taiwanese equipment, the design of the board was pushed instead of the mechanical gripper structure. One is that the gripper will cause damage to expensive materials, and the second is that the press device and the countertop are all designed to Guaranteed high quality after processing. It should be noted that the occurrence of a crevice in the diffuser of the light guide plate and the detachment of the film into the dust means waste.
There is still a fatal problem in the processing of acrylic sheets with woodworking equipment. The quality of a certain thickness of acrylic sheet is very large, and a large friction force is generated during the processing, so that the film attached to the sheet will inevitably be damaged. The waste is caused. In fact, many plate manufacturers are at the expense of the bottom plate, so the loss will be a very large amount for many years. The foreign-style pneumatic pontoon design is adopted, which can minimize the friction between the workpiece and the equipment and avoid unnecessary loss. At the same time, the flat workbench also ensures the smoothness of the workpiece processing, which ensures the accuracy and quality.
So why do many companies now use woodworking machinery to process acrylic sheets? I think it may be that many companies use woodworking reciprocating saws in the early days. The price is relatively low. Later, using electronic cutting saws is also a continuation of thinking. Woodworking equipment is rarely used in relatively high electronics industries such as the television industry.
