It is arranged in parallel, the termination of the horizontal component of L-type coolant guide passage 13 is constituted to the diamond wires band being made up of diamond wire 18
The nozzle 15 of coolant is sprayed on 16.Coolant mainly has 3 effects：One is cooling effect；Two be lubrication；Three be to rinse
Effect.
A kind of course of work of multi-rib grinding processing unit (plant) of the present invention：
Before processing for the first time, or after actinobacillus wheel diamond wire is used up, installation work is carried out.First control take-up pulley and
The synchronous slow rotation of actinobacillus wheel, left guide wheel, right guide wheel and contact wheel, by line as the rotation of each wheel is slow around up.Buddha's warrior attendant
Stone line by strainer enters grinding system after being come out from take-up pulley, by diamond wire be put into first of left guide wheel it is U-shaped recessed
In groove in (if desired, the aids such as scriber can be used), first U-shaped groove for sequentially entering right guide wheel, contact wheel
First V-type groove in.Diamond wire will enter line displacement when turning again to left guide wheel, be wound in the U-shaped groove of Article 2, so
Circulation is gone down, directly around last first U-shaped groove of right guide wheel, on the wide line rows of an about 80mm, eventually passes back to receive
Line wheel.Diamond wire passes through strainer during wiring, but it does not work.Cutting speed is run from the zero slow 5m/s that increases to
For a period of time, after diamond wire is stable, cutting speed is gradually stepped up until reaching 20m/s, the cutting of increase both sides
The tensile force of line is until reaching 33N.
Bar is fixed on workbench sliding block, workbench moves closer to contact wheel until workpiece connects with diamond wire row
Touch, grinding is carried out according to feed speed is preset.
After the completion of grinding, workbench leaves contact wheel, and decelerating through motor is simultaneously static, and workpiece is taken out from workbench sliding block.
Next bar is reloaded to be processed.
When diamond wire is that diamond wire will be used up on running stores, take-up pulley, it should change in time.In order to reduce during thread-changing
Between, take-up pulley directly is changed with the wheel hub for filling new line, take-up pulley actinobacillus wheel reversion when processing again, when the last time is processed
Take-up pulley is as actinobacillus wheel, and actinobacillus wheel during last time processing carries out ensuing processing as take-up pulley.
