切入鋸中的刀片有多薄


2

我最近購買了一把斜鋸和鋸片。鋸是Mac Allister MSPS1200,它是英國的泰坦牌,與許多廉價的類似。刀片是一個很好的弗洛伊德1.7毫米切口。

我現在檢查了鋸的手冊,上面說要使用鋸齒,鋸齒的切角範圍為2.2至3.5毫米。

我想知道,最糟糕的情況是什麼?是否由於刀軸螺母未正確鎖定而導致極限?可以用0.5mm的墊圈固定嗎?

我還沒有修剪賽道碎片保護罩,所以這不是問題。

First and foremost, please note this warning from the manual:

Fitting of other purpose or different sized blades will void the warranty.

Needless to say, you are doing this at your own risk.

With the above out of the way, I have run all the tests that I needed: the blade is fixed and has no play (which suggests that the harbour nut is fully threaded as suggested by jdv). The saw has no riving knife so that is not an issue. It does have an anti-kickback mechanism which is a mechanical lock on the plate-rail connection so it still works.

From my tests, the kerf that the new blade leaves behind is 1.7mm along the whole cut (checked with a caliper). The harbour seems perfectly locked in place, there is no vibration and the cuts are straight and square. I must say it seems a weird limitation but I guess it is just that they did QA with a limited set of blades and they don't want to take responsibility over use outwith range.

I have been using the saw with the thinner blade for a while now and it performs beautifully, leaving straight clean cuts every time.
