Hey there, folks! I’m a supplier of cold rolled steel, and I often get asked about the best cutting parameters for machining this stuff. Cold rolled steel is super popular because it’s got a smooth finish, tight tolerances, and great mechanical properties. But getting the right cutting parameters is crucial to ensure a high – quality cut and efficient machining process. So, let’s dive into the details. Cold Rolled Steel<\/a><\/p>\n

<\/p>\n

Understanding Cold Rolled Steel<\/h3>\n

First off, let’s quickly go over what cold rolled steel is. It starts as hot rolled steel, which is then further processed at room temperature. This cold – rolling process makes the steel stronger, gives it a better surface finish, and more precise dimensions. There are different grades of cold rolled steel, like 1010, 1020, and 1045, each with its own set of properties. For example, 1010 is relatively soft and easy to machine, while 1045 is stronger and has more carbon content, which can make it a bit more challenging to cut.<\/p>\n

Cutting Parameters<\/h3>\n

1. Cutting Speed<\/h4>\n

Cutting speed is all about how fast the cutting tool moves across the surface of the cold rolled steel. It’s usually measured in surface feet per minute (SFM). The right cutting speed depends on a few factors, like the type of tool you’re using and the grade of the cold rolled steel.<\/p>\n

For high – speed steel (HSS) tools, when machining a softer grade like 1010, you can start with a cutting speed of around 70 – 100 SFM. But if you’re using carbide tools, you can crank it up to 200 – 300 SFM. For a harder grade like 1045, HSS tools might work well at 40 – 60 SFM, and carbide tools can handle 150 – 250 SFM.<\/p>\n

If the cutting speed is too slow, the tool will rub against the steel instead of cutting it cleanly. This can lead to a lot of heat build – up, which wears out the tool quickly and gives you a poor surface finish. On the other hand, if the speed is too high, the tool can break or chip, and you might also get a lot of vibration during the cutting process.<\/p>\n

2. Feed Rate<\/h4>\n

Feed rate is how fast the workpiece moves relative to the cutting tool. It’s measured in inches per revolution (IPR) for turning operations or inches per tooth (IPT) for milling. A higher feed rate means you can remove more material in less time, but if it’s too high, it can put too much stress on the tool and cause it to fail.<\/p>\n

When using HSS tools on cold rolled steel grade 1010, a feed rate of 0.003 – 0.006 IPR for turning can be a good starting point. For carbide tools, you can go up to 0.006 – 0.010 IPR. In milling, for grade 1010 with HSS tools, an IPT of 0.002 – 0.004 might work well, and for carbide, 0.004 – 0.008.<\/p>\n

For a harder grade like 1045, you’ll want to lower the feed rate a bit. With HSS tools, try 0.002 – 0.005 IPR for turning, and with carbide, 0.005 – 0.008 IPR. In milling, for HSS on 1045, use 0.001 – 0.003 IPT, and for carbide, 0.003 – 0.006 IPT.<\/p>\n

3. Depth of Cut<\/h4>\n

The depth of cut is how deep the cutting tool goes into the workpiece. It’s important to choose the right depth of cut because if it’s too shallow, you might not be removing enough material efficiently. But if it’s too deep, it can put a lot of stress on the tool and cause excessive wear.<\/p>\n

For roughing operations on cold rolled steel, a depth of cut of 0.1 – 0.3 inches can be a good starting point for most grades. For finishing operations, you’ll want to go much shallower, like 0.005 – 0.015 inches. When using HSS tools, you might want to keep the depth of cut on the lower side to avoid overloading the tool. Carbide tools can generally handle deeper cuts because they’re more wear – resistant.<\/p>\n

Coolant and Lubrication<\/h3>\n

Using coolant or lubricant is also super important when machining cold rolled steel. Coolant helps to reduce heat generated during the cutting process. It can also flush away chips, which keeps the cutting area clean and prevents the chips from re – cutting into the workpiece.<\/p>\n

There are different types of coolants, like water – based and oil – based. Water – based coolants are great for general machining because they’re cost – effective and have good cooling properties. Oil – based coolants provide better lubrication, which can be beneficial when machining harder grades of cold rolled steel or when you need a really good surface finish.<\/p>\n

Tool Selection<\/h3>\n

The type of tool you use also plays a big role in the cutting process. As I mentioned earlier, HSS tools are cheaper and work well for low – speed machining of softer grades of cold rolled steel. They’re easy to sharpen, but they don’t last as long as carbide tools.<\/p>\n

Carbide tools are more expensive upfront, but they offer much higher cutting speeds and better wear resistance. They’re a great choice for high – volume production or when machining harder grades of cold rolled steel. There are different geometries of carbide inserts available, like triangular, square, and round, and you can choose the one that’s best suited for your specific machining operation.<\/p>\n
