1. Frame type sand saw (row saw or saw) can be divided into upper swing type (or pendulum type sand saw), translation type and compound swing type according to the movement path of the saw frame. (1) Upper pendulum sand saw Basic structure: as shown below 
Figure 1 Pendulum type sand saw main motor, flywheel, connecting rod, crank, saw frame cantilever, saw frame, saw blade, four-column frame, screw, lifting motor auxiliary equipment: mortar pump, sprinkler, steel sand adder, steel Working principle of sand separator, hydraulic tensioner and waste trolley: The motor drives the large connecting rod to push the saw frame for simple reciprocating pendulum movement, so that the steel saw blade drives the steel sand abrasive to squeeze, grind the stone and complete the saw Cutting work technical performance: Advantages: thinner saw blades (4.2-4.8mm) can be used, low energy consumption, low sawing consumption, high yield, simple movement, less equipment wear and low maintenance costs. Disadvantages: large proportion of empty travel (3/4~4/5), low efficiency (10~20mm/h) (2) translational frame saw (diamond frame saw and translational sand saw) Horizontal and vertical, the horizontal frame sawing machine has its saw blade for horizontal movement, while the vertical frame saw machine has its saw blade for vertical movement. Basic structure: less saw frame cantilever, more saw frame guide main motor, flywheel, connecting rod, crank; saw frame, saw frame guide, saw blade, four-column frame, screw, lifting motor auxiliary equipment: mortar pump, slurry truck , steel sand adder, steel sand separator, hydraulic tensioner, block trolley. Working principle: The motor drives the connecting rod to push the saw frame along the saw frame guide rail for horizontal reciprocating linear motion. During the movement, the saw blade always squeezes the steel sand to grind the stone, and there is no invalid air travel. Technical performance: Disadvantages: Thicker saw blade (6mm) should be used, high energy consumption (requires larger power main motor drive), high saw consumption, high cost and low yield. Advantages: fast sawing speed, no air travel, high efficiency (30 ~ 40mm / h).

However, due to the complicated structure of the swinging system, the wear is large and the maintenance workload is large.

The number of saw blades can be single or multiple. 4. Diamond wire saw 
Figure 10 Single rope diamond wire saw 
Figure 11 Multi-rope diamond wire saw 1 Basic structure: body frame, beaded rope drive wheel, guiding theory, beam frame lifting drive and guiding system, beaded rope tensioning system, electronic control system, etc. 2 Working principle: Using the beading Diamond particle cutting stone 3 Technical performance (compared with frame saw) a. The structure and installation foundation of the sawing machine is relatively simple, the auxiliary equipment is less, the floor space of the workshop can be reduced by 1/2~2/3; b. The sawing efficiency is high , sawing medium-hard granite plates, can be sawed 250m2 a day, equivalent to the efficiency of two large frame saws with 120 saw blades; c. Easy to operate, high precision sawing, multi-rope diamond bead saw It can quickly change the thickness of the processed sheet; d. The sawing surface of the sheet is flat, and the possibility of the steel sand residue being embedded in the sawing surface of the sheet is eliminated, so that the grinding and polishing time is reduced by 20%; e. The sawing noise is small, work Good environment; f. Low energy consumption, about 30% lower power consumption compared with frame type sand saw; g. Consumable materials are greatly reduced, and environmental pollution is small. The frame saw consumes 3kg of steel grit, 1.5kg of saw blade and 2kg of lime per sawing of granitic granite slab, while the diamond wire saw consumes only 0.01kg of diamond rope. It is roughly estimated that the use of frame saws will require the disposal of 325,000 kilograms of waste mortar per year, which is conceivable for the seriousness of environmental pollution. Taking granite slabs with an annual output of 50,000 m2 as an example, the waste slag produced by the diamond wire saw is only about 1.5% of the frame type sand saw, and the waste slag has a single component and convenient external treatment. Therefore, the diamond wire saw is an environmentally friendly mechanical device for sawing stone slabs. 5. Diamond Band Saw: Small-sized stone sawing of precious stone The basic shape of the diamond band saw is similar to the woodworking band saw of sawn wood. The difference is that the diamond band saw is welded with diamond sawtooth on one side of the steel strip. The two ends of the steel strip are welded and integrated to form a closed loop belt, so it is called a band saw. The main difference between it and the gang saw is that the base is a flexible steel strip, which requires diamond welding, strong bonding, and can be bent and bent like a belt. Band saws are generally very thin (thickness 1.0 to 2.0 mm) and very long (about 5 to 8 m), mostly made by electroplating. Saw width 3mm, can cut 2mm thick plate 6.

Diamond circular saw machine (tube saw) The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow.
