I. Overview
SCM-200 double-side grinding machine consists of base, grinding power head, variable speed drive system, electric control device and other parts. The whole machine is easy to operate and the automatic feed performance is stable. SCM-200 automatic double-face grinding machine is a necessary main equipment for making standard samples of non-metallic solids such as rock ore and concrete. This machine can work with the coring machine and stone cutting machine produced by Shanghai Ruifeng Instrument Manufacturing Co., Ltd., and it can process the high-precision cube or cylinder test sample you need.

Third, SCM-200 double-sided grinding machine works
1, SCM-200 double-sided grinding machine table reciprocating by the motor driven gearbox, the output slow lead screw work, for reverse rotation, screw nut fixed under the table, which drives the table for reciprocating.
This machine grinding head is a professional diamond grinding wheel, and it is directly installed on two special motors. It is driven forward or backward by two transverse worktables. It can be automatic and manual. Push the handle forward when it is automatic. Pull the handle back when it is manual. Each screw is 3MM.
The specimen holder and two grinding wheels of the worktable were carefully adjusted before leaving the equipment to ensure the perpendicularity and parallelism of the specimens that were ground. Each grinding of two parallel surfaces, six surface cube specimens, only need to be ground three times, each time to be accurate, so that the sample can be worn to meet the requirements, SCM-200 double-sided grinding machine The control buttons are respectively mounted on the two power heads for easy operation. Due to the use of water cooling and splashing, the appliance uses a safe voltage of 36V. Since the power supply voltage and the operating motor voltage are 380V, the unit must be reliably grounded, otherwise a safety accident will occur. Therefore, the power supply cannot be reversed, otherwise it will damage the machine.
Fourth, SCM-200 double-sided grinding machine installation and commissioning
Before installing the double-side Sander, it is necessary to understand the details of the installation, commissioning, and operation in the manual.
(1) The double-side sander is preferably installed on the cast foundation. The ground must be flat and firm, and the mechanical bolts must be fixed to avoid vibration when the machine is working.
(2) After installation, all parts of the machine tool shall be cleaned of rust-proof materials. After cleaning, add mechanical lubricant to the lubricating surfaces and guide rails. Then turn the handwheel and grinding disc by hand to check if the rotation is normal.
(3) Turn on tap water.
(4) Check whether the circuit has any control elements, fuses, connectors, loose connections, dropped wires, etc.
(5) The machine must have reliable grounding, and it can be turned on after checking.
(6) Turn on the power button, press the grinding head button, and immediately press the stop button to see if the rotation direction of the grinding head rotates in the direction of the arrow, and never allow the rotation in the opposite direction.
(7) Press the workbench button again and the workbench reciprocates.
(8) It is flexible to push the manual and automatic handle on the side of grinding power head. Otherwise, add lubricant to the sliding part. Push a few more times. The impact block on both sides of the worktable is used to adjust the automatic feeding amount of the grinding wheel. The feed amount is adjusted according to the hardware degree of the sample. The maximum range of adjustment is not allowed to exceed two cells. The automatic feed amount of the grinding head is One time.
(9) Open the water switch on the workbench fixture and the cooling water should be blown out. The flow rate should be sufficient.
Fifth, the use of SCM-200 double-sided grinding machine
Steps (1), clamp the sample block, pay attention to both sides of the symmetry, close to the fixture.
(2) Withdraw the two grinding heads so that the specimen cannot hit the grinding wheel when the table moves.
(3) Install a protective cover and turn on the water switch.
(4), Kai total power switch.
(5), start the grinding head button to make the grinding head rotate in the direction of the arrow, never allow reverse.
(6) Press the workbench button.
(7) Manually feed the grinding head so that it can be ground. It is necessary to automatically push the handle to the automatic position. The two grinding heads can be ground separately. Grind the handle to the manual position and reciprocate it several times. Ensure the specimen finish.
(8), grinding out after grinding head.
Six, SCM-200 double-sided grinding machine notes
Each time the specimen is clamped, the fixture and sample surface must be flushed. Otherwise, the residual material will reduce the precision of the specimen grinding, and each positioning must be accurate.
At any time during automatic grinding, manual feeding is not possible. Otherwise, the grinding wheel and equipment will be damaged. Manual feed can only be performed manually.
(3) After the automatic grinding is finished, stop the work table first and stop grinding the head afterwards.
(4) During the grinding process, attention should be paid to whether the flow of coolant is sufficient. Too little will accelerate the damage of the diamond grinding wheel.
(5) Do not knock the diamond grinding wheel, otherwise it will affect the service life. The new grinding wheel must use ordinary corundum grinding wheel openings before use, grinding will be sharp.
(6) If abnormal noise occurs in the grinding process, check the machine immediately.
(7) Each time the work is carried out, the reciprocating table and the grinding head working rail part and its lubrication part are lubricated.
(8) For the first time, the gear box should be filled with oil. Since the grinding wheel rotates at a high speed and the worktable reciprocates, it must pay attention to safety when working.
(9) The diamond grinding wheel is a wearing part. Take care not to collide, damage or wear and replace it in time.
(10) Pay attention to the nut rotation when loading and unloading the grinding wheel. Be sure to tighten the nuts after installation to prevent accidents.
(12) Each time you turn on your machine, you must check whether the grinding wheel collides with the workpiece or the fixture and other parts. After careful inspection, you can start the machine.
(13) When the table is commuting at both ends, if slight jitter is normal, please feel free to use it.
(14) Correct the parallelism and verticality of the fixture and grinding wheel at regular intervals.
(15) It is necessary to correct the parallelism and verticality of the fixture and the grinding wheel in time when the precision of the sample is found to decrease. 16) The motor must be operated indispensably, otherwise the motor may be damaged.
Seven, maintenance and maintenance
(1) After the use of the SCM-200 double-side sander, the residual rock residue on the workbench should be cleaned. And wipe the water stains, grinding head to clean the table and add oil. The traverse table under the guide rails at both ends of the lubricating oil, after a certain period of time, between the screw and the nut, and the clutch to add lubricating oil Chengdu, to prevent rust.
(2) Grinding head work guides should be checked frequently to prevent loosening.
(3) Always check the grinding wheel to prevent loosening.
(4) Regularly check the parallelism and verticality of the grinding wheel and fixture and find that the problem is corrected in time.
(5) SCM-200 double-side grinding machine is a consumable product, and should be replaced after wear.
