Abstract
The invention discloses a processing method of high-hardness rolls, comprising the following steps: (1) the roll with the hardness of 86HSD to 99HSD is placed on a lathe, a CBN polycrystalline blade is used as a lathe tool for carrying out rough machining to the roll at the cutting speed of 50 to 90m/min, the feed amount is 0.7 to 1.2mm/r, and the cutting depth is 0.5 to 1.5mm; (2) the CBN polycrystalline blade is used as the lathe tool for carrying out semifinishing machining to the roll at the cutting speed of 100 to 180m/min, the feed amount is 0.35 to 0.5mm/r, and the cutting depth is 0.2to 0.5mm; and (3) the CBN polycrystalline blade is used as the lathe tool for carrying out finishing machining to the roll at the cutting speed of 200 to 250m/min, the feed amount is 0.15 to 0.3mm/r,and the cutting depth is 0.1 to 0.5mm. The method has short processing time, high efficiency and low cost.
Description
Technical field
The present invention relates to a kind of processing method of roll, be specifically related to a kind of processing method of high-hardness roller.
Background technology
The processing of roll mainly is grinding at present.But the hardness of the roll after quenching can reach 86HSD～99HSD usually, for the roll of high rigidity like this, adopts grinding length consuming time, and also very big for the consumption of emery wheel, and processing cost is higher.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, a kind of processing method of processing weak point consuming time, high-hardness roller that cost is low is provided.
The technical scheme that realizes the object of the invention is: a kind of processing method of high-hardness roller, have following steps: the hardness after 1. will quenching is that the roll of 86HSD～99HSD is placed on the lathe, carry out roughing as lathe tool with the cutting speed breaker roll of 50～90m/min with CBN glomerocryst blade, its amount of feeding is 0.7～1.2mm/r, and cutting depth is 0.5～1.5mm; 2. with CBN glomerocryst blade as lathe tool with the cutting speed of 100～180m/min again breaker roll carry out semifinishing, its amount of feeding is 0.35～0.5mm/r, cutting depth is 0.2～0.5mm; 3. with CBN glomerocryst blade as lathe tool with the cutting speed of 200～250m/min again breaker roll carry out fine finishining, its amount of feeding is 0.15～0.3mm/r, cutting depth is 0.1～0.5mm.
The present invention has positive effect: the CBN glomerocryst blade (CBN refers to cubic boron nitride) that (1) the present invention adopts is the superhard cutter that is polymerized under HTHP with the CBN micro mist, it has high red hardness, high tenacity, good chemical inertness and low-friction coefficient, can make Roller Machining surface heat transfer amount very little like this, thereby can not influence the roll product surface quality.(2) the present invention adopts turning processing to replace original grinding to process the roll of high rigidity, and make and process weak point consuming time, the efficient height, cost is low.(3) mode of employing syllogic of the present invention processing is carried out machined to high-hardness roller, has improved work efficiency greatly, and the used time need only 84min among the embodiment 1; And process on the M1380 grinding machine as if same roll is placed on, then need 490min just can finish, consuming time longer.
The specific embodiment
(embodiment 1)
The hardness of the roll after the quenching that present embodiment adopts is 95HSD, and barrel length is 1450mm, barrel diameter φ 380mm.The lathe that adopts is the C61125 lathe.
Processing method is: 1. this roll is placed on the lathe, carries out roughing as lathe tool with the cutting speed breaker roll of 60m/min with CBN glomerocryst blade, its amount of feeding is 1mm/r, and cutting depth is 1mm; 2. again with CBN glomerocryst blade as lathe tool with the cutting speed of 120m/min again breaker roll carry out semifinishing, its amount of feeding is 0.5mm/r, cutting depth is 0.5mm; 3. again with CBN glomerocryst blade as lathe tool with the cutting speed of 210m/min again breaker roll carry out fine finishining, its amount of feeding is 0.3mm/r, cutting depth is 0.10mm.Whole process only needs 84min to finish, and roller surface UT detects and EDDY CURRENT all shows normally.
(embodiment 2～embodiment 5)
The processing method of each embodiment is substantially the same manner as Example 1, and difference sees Table 1.
Table 1
(Comparative Examples)
This Comparative Examples is ground processing for adopting the M1380 grinding machine to the roll of embodiment 1, and see Table 2 its process time.
Table 2
| ? | Comparative Examples |
| Roll hardness (HSD) | 95 |
| Roll barrel length (mm) | 1450 |
| Barrel diameter (mm) | 380 |
| Corase grind machines the time (min) | 150 |
| Half correct grinding machines the time (min) | 160 |
| Correct grinding machines the time (min) | 180 |
By table 1 and table 2 as can be seen, Vehicle Processing total consuming time be 84min, and mill processing always consuming time be 490min.The rough turn time of machining/corase grind time of machining is that 18.6%, the half finish turning time of machining/half correct grinding time of machining is 18.1%, and the finish turning time of machining/correct grinding time of machining is 5%.Therefore Vehicle Processing is compared with mill processing weak point consuming time, efficient height.
Claims (1)
1. the processing method of a high-hardness roller, it is characterized in that having following steps: the hardness after 1. will quenching is that the roll of 86HSD～99HSD is placed on the lathe, carry out roughing as lathe tool with the cutting speed breaker roll of 50～90m/min with CBN glomerocryst blade, its amount of feeding is 0.7～1.2mm/r, and cutting depth is 0.5～1.5mm; 2. with CBN glomerocryst blade as lathe tool with the cutting speed of 100～180m/min again breaker roll carry out semifinishing, its amount of feeding is 0.35～0.5mm/r, cutting depth is 0.2～0.5mm; 3. with CBN glomerocryst blade as lathe tool with the cutting speed of 200～250m/min again breaker roll carry out fine finishining, its amount of feeding is 0.15～0.3mm/r, cutting depth is 0.1～0.5mm.
