Description
Technical field
The present invention relates to a kind of for the alloy cutter of milling high-speed steel roll and milling process method, belong to Machine Design
And maintenance technique field.
Background technology
Recently as the change of the demand in market, various new roller materials continue to introduce new, and forge high speed steel
Matter roll also comes into being.The application of high-speed steel roll is the important component of modern Rolling production development, is steel and iron industry
Another major transformation in development history after microalloying, Controlled Rolling And Controlled Cooling.High-speed steel roll, also known as high carbon high-speed steel
Composite roll, for the working layer of roll using high carbon high-speed steel, the core material of roll uses spheroidal graphite cast-iron more.High-speed steel rolls
Containing alloying elements such as substantial amounts of V, W, Cr, Mo, Nb in roller, there is higher room temperature hardness（HS82~90）, while have good
Good high temperature red hardness feature still ensures that more than HS78 at more than 500 DEG C, therefore has excellent high temperature abrasion resistance, at present
It is widely used in Rolling production.With high-speed steel roll substitution ferrosteel roll, high-chromium iron-cast roller, high-nickel-chromium molybdenum infinitely is chill
Roll and Needle-like ductile iron roll, for improving amount of rolling, extending the roll change cycle with good effect.
In the preparation process of high-speed steel roll, since high-speed steel roll has high rigidity, high tenacity and high abrasion in itself
Property, and it requires have the pre- allowance of larger processing in heat treatment process, therefore extremely difficult carry out Milling Process.If with
Conventional tool carries out Milling Process, and milling process can generate very high heat, and the cutting edge abrasion of cutter is very fast, easily makes alloy cutter
It bursts apart or even generates knife phenomenon, cause quality accident, and the loss of cutter is fast, the service life is low；Moreover, by conventional tool milling
It cuts that the roller surface quality of processing is poor, and then affects the performance of high-speed steel roll.Since conventional tool is by cutter sheet
Body geometric angle and material limitation, there are chip breaking difficulty, knives during the high-speed steel roll with high rigidity, high tenacity is processed
Tool cutting edge quick abrasion, point of a knife burst apart phenomenon, cause processing efficiency low.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of alloy cutter for milling high-speed steel roll and milling
Method.
In order to solve the above technical problems, the technical solution used in the present invention is：
A kind of method for milling of high-speed steel roll including rough milling, finish-milling process, rolls high-speed steel using machine folder alloy cutter
Roller carries out milling, the gear bits platform of 1.2~1.8mm of protrusion is provided on the knife face of the mechanical clamped cutting tool, cutter tool cutting edge angle is 82 °；
The cutting parameter for rough milling process is：Linear velocity Vc=10-12m/s, bite f=2-3mm, feed speed ap=5-
10mm/min, the cutting parameter of finish-milling process are：Linear velocity Vc=14-18m/s, bite f=1-2mm, feed speed ap=0.1-
1mm/min。
Further improvement of the present invention is：Rough mill flat face allowance 1mm, keyway allowance 1mm after process.
Further improvement of the present invention is：The height of the gear bits platform is 1.5mm, and the distance of cutting edge to gear bits platform is
The angle of 1mm, gear bits platform and vertical direction is 56 °.
By adopting the above-described technical solution, the technological progress acquired by the present invention is：
Method using the present invention can improve the efficiency of milling high-speed steel roll, reduce the abrasion and damage of cutter.This
Invention is by designing gear bits platform, the change to tool geometry angle and material so that roller surface after milling is smooth, turning is fast
Degree is fast, and cutting edge roundness is not easy to wear, bursts apart, and service life of turning cutting tool is by original every 0.8 roll raising of tool sharpening
1.2 rolls can be processed to single blade tool, significantly reduce the loss of cutter.Method using the present invention solves high-speed steel and rolls
Chip breaking problem is difficult to when surface milling is cut, a large amount of tool changing is saved, whets a knife the time（At least tool changing 4 times originally of every roll, reconditioning cutting edge 2
Secondary, the saving time is no less than 40 minutes/）, method using the present invention must when milling process is no longer because iron filings winding cutter
Removal must be shut down and twine bits, blade durability improves 50%, completely solves safety in production, the hidden danger of site environment management.Using this
During the method processing of invention, the continuous length of the iron filings milled out does not exceed 20mm.
The present invention makes the milling process processing during forging high-speed steel roll by being optimized to processing and milling parameter
Efficiency improves more than 50%, and the time processing qualification rate of roll product reaches 100%.

Specific embodiment
The present invention is described in further details below in conjunction with the accompanying drawings：
A kind of method for milling of high-speed steel roll including rough milling, finish-milling process, rolls high-speed steel using machine folder alloy cutter
Roller carries out milling, rough mills flat face allowance 1mm, keyway allowance 1mm after process.The cutting parameter of each Milling Process process is as follows：
The cutting parameter for rough milling process is：Linear velocity Vc=10-12m/s, bite f=2-3mm, feed speed ap=5-
10mm/min；
The cutting parameter of finish-milling process is：Linear velocity Vc=14-18m/s, bite f=1-2mm, feed speed ap=0.1-
1mm/min。
Machine folder alloy cutter is box-shaped molding cutter used in milling, in the centrally disposed mounting hole 1 of cutter block, in cutter block
Four angles are point of a knife 3, and the radius of corner of point of a knife 3 is R3, and four sides of cutter block are cutting edge 2, cutter tool cutting edge angle（Cutting edge and water
Square to angle）For 82 °（The tool cutting edge angle of general cutter is 75 °）, so as to improve reduction radial cutting force, make cutting light
Soon, vibration cutting is reduced.On the knife face of cutter block, the inside of cutting edge 2 be provided with gear bits platform 4, gear bits platform 4 height of projection be
1.2~1.8mm, preferably 1.5mm.The distance at cutting edge to 4 edge of gear bits platform is 1mm, gear bits platform 4 and the folder of vertical direction
Angle is 56 °.The tool life is high, chip breaking is brisk, improves Milling Process efficiency, reduces processing cost.
Since high-speed steel roll contains the alloying elements such as substantial amounts of V, W, Cr, Mo, Nb, itself has high rigidity, high tenacity
And high-wearing feature, and it requires have the pre- allowance of larger processing to prevent from deforming in heat treatment process, rough mills rear flat
Face 1mm, keyway allowance 1mm are rough milling process for surplus is big, characteristic of high tenacity is added using cutter shown in Fig. 1, Fig. 2
Work.Since the hardness of roll body of roll is big, CBN tool sharpening of the material for FBC9000 is used.The present invention passes through processing and milling
The optimization of parameter makes the milling process processing efficiency during forging high-speed steel roll improve more than 50%, the one of roll product
Secondary passing rate of processing reaches 100%.
