Handle 29, makes cuboid rock sample vertical with diamond wire 14, and rotary work-table advances handwheel 27, after adjusting cutting position, twists
Tight workbench back-up wrench, starts scroll saw motor 10, the end face of cuboid rock sample is cut it is desirable to both ends of the surface after being cut
The depth of parallelism is less than 0.1mm, after the completion of cutting, rotates scroll saw lifting handwheel 8, raises diamond fretsaw 1, and reversion workbench pushes away
Enter handwheel 27, the platform 2 take off cuboid rock sample of deactivating, clean surface landwaste, and as lower step rock sample to be cut 5.
2nd, rock sample cutting, refering to Figure 10,
A, the rock sample size empirically requiring, install round die block 23 and the locating groove of φ 50mm on cutting table 15
24, rotate the holder handle 25 of cutting table 15 upper end, fixed rock sample 5 two ends to be cut it is ensured that will not produce with round die block 23
Life is rocked and displacement, and rotary work-table advances handwheel 27, after cutting table 15 is moved to immediately below diamond wire saw 1, tightens
Workbench back-up wrench is so as to no longer move horizontally.
B, rotate scroll saw lifting handwheel 8, decline diamond wire saw 1 until diamond wire 14 and locating groove 24 away from
From less than 5cm, tightening fixing bolt in fixing threaded hole 9, rotate cutting table horizontal adjustment handwheel 18 and vertical adjusting handle 20,
Adjust the position of rock sample 5 to be cut, so that diamond wire 14 is contacted with rock sample 5 to be cut through locating groove 24, tighten cutting table water
Flat back-up wrench.
C, startup scroll saw motor 10, open cooling gas jets 13, the slow rotation vertical adjusting handle of cutting table 20, start
Vertical cutting is carried out to rock sample 5 to be cut, until diamond wire 14 is contacted with round die block 23, tightens cutting table level vertical solid
Determine spanner 21 so as to not produce vertical deviation.
D, uniform speed slow rotate the rotation hand wheel 26 of the device side that rotates in a circumferential direction, and start to carry out 360 ° of weeks to rock sample 5 to be cut
To cutting, close scroll saw motor 10 and cooling gas jets 13 after the completion of cutting, unclamp the vertical back-up wrench of cutting table 21 and work
Station back-up wrench, falls cutting table 15 height, removes locating groove 24, do not take off cylindricality rock sample.
3rd, rock sample polishing, refering to Figure 11,
A, rotary work-table propulsion handwheel 27, cutting table 15 are moved to immediately below polishing cylinder 32, tighten workbench and fix
Spanner is it is ensured that it no longer moves horizontally.

It is: the method that this rock sample preparation facilitiess of low-intensity containing weak interface prepare sample:
First, cuboid sillar cutting:
A, rock cutting machine is cut into fritter rock, be placed on the clamping rotating disk (16) of workbench, tighten and hold out against seat top
Spanner (31), fritter rock is fixed to clamp；
B, the bolt taking off in diamond wire saw steel bracket (7) fixing threaded hole, rotate diamond wire saw lifting handwheel (8),
Diamond wire saw (1) is risen to highest, rotary work-table propulsion handwheel (27), rotating disk (16) will be clamped and move to diamond wire
The underface of saw (1), rock sample angle according to needed for experiment, rotate clamping rotating disk handle (29), rotating disk (16) rotation will be clamped
To predetermined angular；
C, startup scroll saw motor (10), open cooling gas jets (13), rotate diamond wire saw lifting handwheel (8) and control gold
Diamond wire saw machine (1) declines, and sillar is cut into the cuboid rock sample of certain specification；
D, cuboid rock sample is fixed in clamping rotating disk (16), both ends of the surface is cut it is desirable to the both ends of the surface depth of parallelism does not surpass
Cross 0.1mm, after the completion of cutting, raise diamond wire saw (1) highly, reversion workbench propulsion handwheel (27), platform of deactivating
And take off cuboid rock sample, surface landwaste is cleaned out, as lower step rock sample to be cut；
2nd, cylindricality rock sample cutting:
A, empirically require, install round die block (23) and the locating groove (24) of corresponding size, rotate cutting table upper end
Rock sample two ends to be cut are fixed by holding handle (25) with round die block (23), and rotary work-table propulsion handwheel (27), by cutting table
Move to immediately below diamond wire saw (1), tighten workbench back-up wrench so as to no longer move horizontally；
B, rotation diamond wire saw lifting handwheel (8), decline diamond wire saw (1) until diamond wire (14) and positioning
Draw-in groove (24) distance, less than 5cm, tightens fixing bolt fixed diamond scroll saw (1) highly, rotates cutting table horizontal adjustment handss
Wheel (18) and vertical adjusting handle (20), are made diamond wire (14) be contacted with rock sample to be cut through locating groove (24), tighten
The horizontal back-up wrench of cutting table；
C, startup scroll saw motor (10), open cooling gas jets (13), rotate the vertical adjusting handle of cutting table (20), it is right to start
Rock sample to be cut carries out vertical cutting, contacts with round die block (23) to diamond wire (14), tightens cutting table level vertical solid
Determine spanner (21)；
D, uniform speed slow rotate the handwheel that rotates in a circumferential direction, and start rock sample to be cut is carried out with circumference cutting, after completing 360 ° of circumference cuttings,
Close diamond wire saw (1), unclamp the vertical back-up wrench of cutting table (21) and workbench back-up wrench, reduce cutting table high
Degree, removes locating groove (24), does not take off cylindricality rock sample；
3rd, cylindricality rock sample polishing:
A, rotary work-table propulsion handwheel (27), cutting table is moved to immediately below polishing cylinder (32), tightens workbench fixation and pulls
Handss；
B, startup polishing motor (34), rotate the vertical adjusting handle of cutting table (20), raise cutting table height until polishing cylinder
(32) with cylindricality rock sample contacts side surfaces, tighten the vertical back-up wrench of cutting table (21)；
C, rotate and rotate in a circumferential direction handwheel (26), make cylindricality rock sample carry out circumference polishing along round die block (23), after the completion of polishing,
Close polishing motor (34), unclamp the vertical back-up wrench of cutting table (21) and workbench back-up wrench, fall cutting table (15)
And platform of deactivating, take off the cylindricality rock sample preparing.
