CNC Automatic Marble Polishing Machine
Model: CB/BMF2-2M-20/16 (Upgraded Version)
Difference between one beam and two beamsThere are 7 pieces of abrasives fixed on small polishing plate and 9 pieces of abrasives fixed on big polishing plate. In general, it is more efficient for rough grinding with small plate with 7 pieces of abrasives and the crossbeam swing in slower seed. It is suitable for polishing to fix 9 pieces of abrasives on big polishing plate and the crossbeam swing fast to get perfect polishing gloss. In this way, if there is only one beam for the machine, no matter to fix 7or 9 pieces of abrasives for polishing. It cannot get good polishing effect.We choose the best way to make the machine with two beams for rough grinding and polishing separately. It also can adjust the swing speed of the crossbeam. This design also solves the problems for the polishing plates in different size. With so many years of the efforts and satisfaction from the user, it was proved that two beams are the best way for polishing.
The electric control cabinet fixed in front of the machine, it can get bigger space for electric cabinet and better heat dissipation. It also improved the function of waterproof. For the dust, it adopts the closed cover to prevent the dust and prolong the lifespan of electric component. It is more reasonable to put whole circuit system on steel shelf. This new layout for the electric control system, it is easier for operator to make daily maintenance, solve problem quickly, save time and improve productivity. Electric component passed international certification, to ensure the machine run in efficient, safe and stable. It is easy for customer to get these electric component in the market.
The slab detection unit1）Adopts the ultrasonic to detect and memorize the thickness of slabs without any contact. 2）Combine the mechanical device with sensor to memorize the slab profile.3）Adopts resistance ruler to measure the height of the grinding spindle.4）According to the slab profile and thickness, the detection system can control the heads automatically to lift and fall for polishing, and ensure the crossbeam in accordance with the slab profile to move front and back automatically.In addition, automatic detection of the abrasive consumption for each individual plate, with messages on touch screen to operator and alarm before the abrasive is completely consumed. Minimal raising of the plates and subsequent rapid lowering ensuring a better polishing of the slab sides.
Crossbeam bearing the weight of the polishing heads. The crossbeam built in special design with strong structure and hardly deformation to ensure the quality of grinding products. Each crossbeam fixes 10 pieces of polishing plates. The Maxi. working speed of crossbeam achieves to 60 m/min.
Rough Grinding plate
Each rough grinding spindle unit is equipped with the high efficiency of grinding plate with diameter of 510mm and suitable to fix 7 pieces of abrasive, to ensure high efficiency stability for rough grinding. It is also equipped with special shock-proof and shock absorption unit, suitable to work different stone and get good grinding efficiency.
High efficiency - rough grinding spindle unitRough grind spindle unit is whole cast-iron casting, with high reliability, simple maintenance, good stability. A couple of cylinder fixed in side of casting to control the shaft to lift and fall.For the daily maintenance, automatic laborsaving lubrication system can add oil to prolong the lifespan of the machine. And the water supply which placed above spindle units can feed the water to machine while working.The appearance designs simply, easy to maintain. With tested in recent years, it can achieve the fast speed and high efficient for rough grind with plate of Φ510mm, holding 7 pieces of abrasive.
High brightness-Polishing spindle unit
Polishing spindle unit is whole cast-iron casting, with high reliability, simple maintenance, good stability. For the polishing plate, it is suitable to fix plate of Φ600mm, holding 9 pieces of abrasive. It proved that ensures the higher efficiency and high brightness.
Each polishing spindle unit is equipped with polishing plate with diameter of 600mm and suitable to fix 9 pieces of abrasive, to ensure high uniformity and brightness for polishing and solve the problem for the shadow on polished slabs. It is also equipped with special shock-proof and shock absorption unit, suitable to work different stone. It can reduce the abrasive wastage and reduce the production costs.
The tableThe table is the support structure of the machine, to ensure the flatness and high rigidity in run. Adopt wear resistant steel plate on the table.The thickness of the table increased from 400mm to 450mm to improve the strength of table structure and make table more stable. It can reduce the vibration while machine in run. The conveyor belt slides upon a thick steel table to transport the slabs with perfect flatness, to ensure quality.
Automatic lubrication system
Adopt automatic lubrication system to add oil to the machine in fixed time with fast speed, to save time and troubles for operator, control the usage of lubricating oil, ensure the regular lubricant in the fixed time, effectively achieve the purpose of maintenance, reduce the machinery abrasion and extend lifespan.
Crossbeam transmission systemCrossbeam transmission is controlled by servo system, two pieces for each crossbeam, total 4 pieces. There are advantages as below.1）High precision: achieve closed loop control of the location, speed and moment, make the control more precise.2）Rotation speed: more stable and high speed without distortion.3）Adaptability: ability for overload-resistant is strong, and can bear large torque load;4）Stability: low speed working with stability, little vibration and low noise.5）Timeliness: motors speed up and down with fast response and high accuracy.6）Comfort: motor run with lower heat and decreased noise.
The control and display of spindle
Choices switch to control the lift and fall of the spindle by manual or automatic. It can adjust the fall pressure with adjusting knob and pressure will display on pressure gauge to each spindle unit separately. It is convenient for operator to check and control the lift and fall of the spindle.
Operation panel and touch screenThe operation panel combines press buttons with touch screen, easier for operator to operate and understand. It includes power on/off, program stop, alarm clear, control to beams and belt, waterproof cover lift/fall and emergency stop.Touch screen in 10.1 inch, convenient for operation.
Touch screenOperator can know clearly the functions about the machine with the touch screen. Its functions list as under.User adjustor，Up/down adjustor，Parameter setting，Diagnosis functions，Fault list，Main menu. It can know clearly for all information with above menus, such as the position of polishing plates, abrasive consumption, slabs thickness, alarm for the problem, etc. It is easier for operator to solve the problem quickly.
Adopt single-arm automatic loader with 12 pieces suction cups for loading slabs with fast speed, to improve productivity, improve good work environment and laborsaving job for workers. Suction cup is in diameter of ?250mm, 4 pieces per row, total 3 rows. The rated load weight is 0.5 ton.
Slab width detection
There are 4 sets of detection components in front of the table. When slab move and touch detection components, it can detects the slab widths automatically and put the slab to the motorized rotation A-Frame at safe, efficient and fast speed.
Motorized rotation A-frame
Slabs can be placed on both sides of the motorized rotation A-frame. While the motorized rotation A-frame is full with slabs, it will rotate 180 ° to load and unload slabs continually. The complete polishing line can work without stop, to improve the production effciency.
