2013-06-19 15:10Use and maintenance of engraving machine spindle

Engraving machine spindle is one of the key components to maintain good electrical engraving and milling machine spindle is to ensure the normal operation of the necessary conditions, so understanding the electrical axis of the structure principle, to acquire all parts (another) sports action is necessary.

First, the electrical spindle start preparatory work before:
1, check whether the spindle holding steady.
2, the cooling water is smooth.
3, the current is normal, the voltage must meet the requirements specified shall not exceed 10%.
4, the wiring is correct, pay attention to reversing the ground.
5, handle clip firmly, so that accuracy in the permitted range.
6, using a pressure cap, collet, knives are reasonable.
Second, the spindle running, you should always pay attention to its dynamic, unusual circumstances, measures must be taken to restore normal operation can continue.
Three, stator, bearing at non-damp, in particular, no flooding.
Fourth, the direction of rotation is counterclockwise, found the opposite direction when the thread simply put any two swap click.
V. Use of the spindle in the voltage, current, temperature, etc. as necessary to monitor the sound to operate within the normal range.
Six, the spindle can not long into overdrive, but it can slow down operation.
Seven, to keep the cooling water flow, water temperature not exceeding room temperature, flow rate of about 3-5L/Min.
Eight, the occurrence of the spindle can not continue to operate, the best fix my company mail, do not own overhaul.
Nine, the pressure cap, collet use.
1, the chuck into the pressure inside the cap, gently turn the retainer until the pressure cap eccentric portion recessed circlip groove, push evenly along the direction of the arrow retainer, you can mount pressure cap.
2, together with the retainer and the pressure mounted on the chuck body cap or machine axis, the cylindrical portion of the tool holder into the hole after wiping, use a wrench to tighten pressure cap were evenly, until the tool firmly until the clip before be used. (Note: Never in the solid state, the tool is not installed pressure cap to avoid damage to the chuck).
Three, tool, use wrench to loosen the pressure cap chuck and tool belt out direction of the arrow push hard retainer to quit, and then need to put other aperture retainer can be.
4, the pressure inside the cap and the shaft outer rib rib rib teeth are fine, must be cleaned before connecting, connecting the first two teeth feel relatively smooth rotation before tightening to avoid both the screw is not tight, but loose high, and even damage to the pressure cap shaft.
5, the event is not tight or loaded knife handle accuracy is not satisfactory, after repeated cleaning and re-loaded knife or invalid, it can only be replaced with new pressure cap, collet. Pressure cap, collet best matching, the use of complementary pressure cap, precision collet to be higher than normal.
6, the pressure cap, collet dimensions must be installed on each blade collet EXTENT PERMITTED specifications are as follows: ER8 Collet ≥ 1-5mmERIIT ≥ 1-7mmER16 Collet Collet Collet ≥ 1-10mmER20 ≥ 1-1.3mmER25 Collet ≥ 1-16mmER32 ≥ 2-20mmER Collet Collet Collet ≥ 3-26m/mER50 ≥ 6-34m / m.
