Band Sawing: Key Ter

https://stankotorg.ru/guide-m42-vs-m51-vs-m71-vs-tct.htm

QuestionAnswer
Blade run-in A new blade works at reduced feed (30–50 % lower) for the first 20–40 minutes.
Blue chip dust Sign that the blade speed is too high or there is not enough coolant.
Curled chip without burning Usually a sign of normal cutting conditions.
Typical emulsion start concentration About 5 % (1 L concentrate to 20 L water), then adjusted to the material.
Emulsion for stainless, heat-resistant steels, titanium About 6–12 % concentration.
Refractometer Instrument for measuring emulsion concentration; the coolant's refractometer factor must be taken into account.
Cut drift The cut line deviates from the intended path; causes include tension, guides, dull teeth, wrong TPI, feed overload and clamping.
Out-of-square cut Constant angle error caused by vise, stop or workpiece seating geometry rather than by blade guidance.
Blade breakage at the weld Typical causes: impact on entry, over-tension, excessive feed on a new blade.
Blade coming off the wheels Typical causes: low tension, oil on the wheels, sudden braking, wrong tooth direction.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
