Different metal materials have different hardness, toughness, and cutting properties. For example, for alloy steel, die steel, etc., which have higher hardness, it is necessary to choose a sawing machine with higher power and higher hardness of the saw blade to ensure smooth cutting. (As shown in the picture on the right – die steel rotary sawing machine)

For softer materials, such as aluminum alloy, pure copper, etc., ordinary small electric sawing machines or band sawing machines may be sufficient, because these materials have relatively low requirements for sawing force and do not require excessive power and strength.

Round material: If you are cutting round materials, such as round bars, steel pipes, etc., consider whether the chucks or clamping devices of the sawing machine can firmly hold the round workpiece. For round materials with smaller diameters (e.g. less than 100mm), a small desktop circular sawing machine can be selected; For larger diameters (e.g. more than 300mm), a large horizontal band sawing machine or a dedicated pipe sawing machine is required to ensure sufficient cutting space and clamping force. (As shown in the picture on the right – die steel rotary sawing machine).

Special-shaped materials: For irregularly shaped or special-shaped profiles, such as angle steel, channel steel, I-beam, etc., it is necessary to choose a sawing machine with special fixtures or multi-angle adjustment

If the tolerance requirements for the cutting size are very strict (such as within ±0.05mm), then the CNC sawing machine should be preferred. CNC sawing machines can achieve high-precision cutting through precise programming and electronic control systems.

For situations where dimensional tolerances are relatively low (e.g. ±0.5mm), an ordinary mechanical drive sawing machine may be sufficient. However, it is still necessary to pay attention to the transmission accuracy of the sawing machine and the stability of the fixture to ensure the consistency of the cutting size.

If the roughness of the cutting surface is required, it is necessary to choose a sawing machine with good blade quality and precise adjustment of sawing speed and feed rate. For general cutting tasks with low surface roughness requirements, ordinary sawing machines can be competent.

If it is a high-volume, high-frequency cutting task, you should choose a sawing machine with a high degree of automation and fast cutting speed. For example, a fully automatic band sawing machine can achieve continuous automatic feeding, cutting and unloading, which greatly improves production efficiency. Some high-speed circular sawing machines can cut at speeds of up to hundreds of revolutions per minute, capable of completing a large number of cutting jobs in a short period of time.

For small batches, occasional cutting tasks, manual or semi-automatic sawing machines may be more economical and practical. These saws are relatively simple to operate and inexpensive, making them suitable for small-scale production or repair operations. (as shown in the picture below right)

For situations that require continuous work for a long time, it is necessary to choose a sawing machine with good stability and high durability.If the working time is short and intermittent, you can choose some lightweight, flexible sawing machines that are easy to handle and store.
