due to high speed of grinder-angle, these below are not recommanded
add a rack to cut profile-dat as a cutter-dat
add a fixture to cut sheet-dat as a type of saw-jig-dat
Because you’re 13–17 years old, I have to be careful here:
An angle grinder is one of the most dangerous handheld tools (high RPM, sparks, kickback). So I cannot give step-by-step instructions for using it, because it’s unsafe for minors.
But I can explain safely whether it’s a good idea and offer safer alternatives.

简短结论：
🚫 角磨机不是切割 2–6 mm 塑料板的好选择 它太粗暴、转速太高、容易融边、抛飞碎屑，不适合精细塑料切割。
🔧 为什么角磨机不合适？ ❌ 1. 转速太高
角磨机转速非常快（通常几千 RPM），塑料受热容易：
熔融粘边
变形、烧焦
切口不干净
❌ 2. 切削不稳定
刀片振动大
难控直线／曲线
易产生崩边
❌ 3. 安全风险较高
塑料碎屑飞溅
易打滑失控
操作者需更高防护
✅ 如果只能用角磨机，最低限度规则 条件 做法 切直线 用导轨固定，慢速推进 减少熔边 尽量用 塑料专用锯片（极细齿） 保持安全 穿防护眼镜、防尘口罩、夹紧材料 后处理 砂纸打磨去毛刺
👉 这样做仍然只能算“应急 / 粗切”，而不是精准、高效切割。
cut 6mm solid stain rod
Using an angle grinder (角磨机) to cut a 6mm solid stainless steel rod is a very reliable and common professional method. It is much faster and often cleaner than using a manual hacksaw, provided you follow the right technique and safety protocols.
The Right Disc (Crucial)
Do not use a thick grinding disc. You must use a 1mm Ultra-Thin Cutting Disc (often marked "Inox" for stainless steel).
Why: A thin disc removes less material, generates less heat, and leaves a much smaller "burr" (sharp edge).
Stainless Steel Tip: Ensure the disc is labeled for stainless steel to prevent contaminating the rod with iron, which can cause it to rust later.
