The FAQ has been answered from the perspective of technical department.
What’s High Speed Steel?
High Speed Steel stands for high speed steal, which is common tool steal. There are 13 types of tool steels provided as 「JIS G4403」 on Japanese Industrial Standards(JIS). The tool steels are distinguished in this standards by 「SKH」. This took from the words Steel, Kougu (tool), High-speed. Their representatives are SKH2・SKH10・SKH51・SKH55・SKH59.
This is an alloy material consisted of carbon as main, and Chromium, molybdenum, tungsten, Vanadium, cobalt and so on.
The degree of hardness is generally 64～68 at HRC (Rockwell Hardness C-scale) . We can change the composition depend on the materials which are processed. This is universal tool steal which is applicable to general steel, aluminum, and stainless steel and so on.
What’s cemented carbide?
Cemented carbide is usually an alloy which is processed by powder metallurgy with tungsten and cobalt is said to be the third hardest after diamond, ceramic. The tools which are made of this cemented carbide is called Carbide tool. Cutting instruments, including our metal slitting saws, are the one of them.
The feature is resistant to abrasion and heat and enables you to shorten the time of cutting greatly with high-speed cutting from high hardness steel to cast iron.
Compared with High speed steel products, this is processed with high accuracy, so improve the result of the surface. Besides, this is so good at resistance to rub that you can decrease the cost with less number of changing tools.
To extend the tool life?
Adding to slowing down the cutting speed, we recommend that you have blades coated.
There is TiN-coating as a kind of coating. TiN-coating is much more resistant to heat, rub, and adhesion than base materials(High speed steel、cemented carbide). It will improve the performance of cutters and extend their life spans to process at higher speed.
Suitable cutting speed for a milling cutter?
There are standards for proper speed depending on your materials of blades and work materials.
First, please enter the specs which you are using, the number of rotation and so on in "Cutting conditions" on our website. Second, please calculate the speed of cutting.
Then, make sure the proper cutting speed on the same page.
How long is the delivery date?
It differs from the type of cutters, materials, and etc, it needs a week at the fastest speed. Regular rate is from two weeks to four weeks.
