Abstract

The utility model discloses a slicer mortar jar relates to lathe technical field, setting up a wall that is less than the casing wall top in the cylindrical cylinder body, cutting off the top and be equipped with a flat board, flat board, wall, cylindrical cylinder body form an airtight space. Reduce the capacity of original mortar jar, under the prerequisite that does not change new mortar change volume, improved the proportion of new mortar, reduced the mortar quantity, practiced thrift the cost, improved cutting ability and silicon chip quality.

Description

A kind of slicer mortar jar

Technical field

The utility model relates to machine tool technology field.

Background technology

Slicer is the thin and machinery of uniform formation's sheet of cutting, at present, cutting monocrystalline silicon is mainly with existing NTC-MWM442DM lathe, cardinal principle is: mortar is at cutting area, utilize the abrasive grains in mortar and silicon rod surface high-speed grinding, because abrasive grains has very sharp keen corner angle, and hardness is much larger than the hardness of silicon rod, so silicon rod can be ground away by mortar gradually.

In order to ensure cutting quality, require higher to mortar quality.Existing NTC-MWM442DM lathe mortar jar capacity is about 230L, and current mortar jar capacity is comparatively large, causes changing the timing of mortar amount one, the ratio of new mortar is relatively low, affects cut quality, if will ensure cutting power and quality simultaneously, require to change more mortar, cause cost to waste.

Summary of the invention

The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of slicer mortar jar is provided, reduce the capacity of original mortar jar, under the prerequisite not changing new mortar replacing amount, improve the ratio of new mortar, reduce mortar consumption, cost-saving, improve cutting power and Si wafer quality.

For solving the problems of the technologies described above, technical solution adopted in the utility model is: arrange a partition lower than casing wall top in cylinder block, and cut off top and be provided with a flat board, dull and stereotyped, partition, cylinder block form a confined space.

As preferably, the plan vertical distance cutting off distance from top circular cylinder body wall is 10cm.

As preferably, cut off high 30cm, wide 29cm.

As preferably, tight Container Volume of Methane 45L.

As preferably, cut off and dull and stereotyped employing corrosion resistant plate.

The beneficial effect adopting technique scheme to produce is: the utility model by arranging the confined space of a partition-type in original cylindrical mortar jar, reduce the capacity of original mortar jar, under the prerequisite not changing new mortar replacing amount, improve the ratio of new mortar, reduce mortar consumption, cost-saving, improve cutting power and Si wafer quality, significantly reduce stria, the ratio of the problem sheets such as tool marks.

In figure: 1, cylinder block; 2, dull and stereotyped; 3, cut off; 4, slurry adding port; 5, lid; 6, motor.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, for an embodiment of a kind of slicer mortar jar of the utility model, a partition 3 lower than casing wall top is set in cylinder block 1, the plan vertical distance cutting off 3 distance from top cylinder block walls is 10cm, cutting off the lower slightly of 3 settings, is to make mortar add smoothly.Cut off 3 tops and be provided with a flat board 2, flat board 2, partition 3, cylinder block 1 form a confined space, arrange dull and stereotyped 2 and can prevent mortar from flowing in partition 3, avoid waste.This use new structure is simple, can reach good effect.

Cutting off 3 high 30cm, wide 29cm, tight Container Volume of Methane 45L, significantly improve the new mortar ratio in mortar jar, thus the cutting power of mortar can be made to be significantly improved, therefore, when ensureing not reduce Si wafer quality, original mortar replacing amount can be reduced.

Cut off 3 and dull and stereotyped 2 and adopt corrosion resistant plate, conveniently draw materials, more firm wear-resisting.

Use procedure:

During use, cylinder block 1 installs a lid 5, lid is arranged slurry adding port 4, slurry adding port is in set dull and stereotyped 2 tops, lid 5 top can mounted motor 6, during work, if need to add new mortar, new mortar can be poured into from slurry adding port 4, mortar can flow in cylinder block 1 by nature.

After adopting technique scheme, for 442 lathes, it is the capacity that the mortar jar of 230L changes 180L into by former capacity, if constant according to original new mortar replacing amount, the words of 80L changed by every cutter 8 cun of monocrystalline, the ratio of new mortar then can become present 44.44% from original 34.78%, significantly improves the new mortar ratio in mortar jar, thus the cutting power of mortar can be made to be significantly improved.Therefore, when ensureing not reduce Si wafer quality, original mortar replacing amount can be reduced.When as kept new mortar constant rate, the mortar replacing amount of 8 cun, every cutter can be reduced to about 63L, thus significantly reduce production cost.Change the new mortar of 70L according to every cutter at present to calculate, new mortar can reduce 10L/ cutter, and new mortar ratio improves 4.1%, and processing cost can reduce by 0.077 yuan/sheet.
