Abstract

The invention provides a machining method for eliminating fine knive-connecting section difference on large planes of a fixed template. The machining method comprises the following steps of: (1) selecting a high-accuracy four-axis coupling horizontal boring and milling machining center, and adopting a knife disc and a blade; (2) roughly milling: distributing the rough-milling cutting amount, machining by twice milling, roughly milling by 6mm for the first milling, and roughly milling by 3mm for the second milling, wherein the linear speed for cutting is 95-105m/min; (3) semi-fine milling: carrying out semi-fine milling, leaving by 0.05mm, wherein the linear speed for cutting is 115-125m/min; and (4) finly milling: finly milling a finish surface by 0.05mm, wherein the linear speed for cutting is 190-210m/min. The machining method provided by the invention has the advantages that the knife-connecting section difference can be effectively eliminated, the smoothness and the brightness of the large planes are guaranteed and no section difference is felt by hands.

Description

A kind ofly eliminate the processing method that the large plane of fixed form connects little section difference of cutter
Technical field
The present invention relates to field of machining, be specifically related to a kind of processing method that the large plane of fixed form connects little section difference of cutter of eliminating.
Background technology
Fixed form is the firm banking when nuclear power generating equipment is installed, and high to the required precision on large plane, the flatness form and position tolerance on large plane is 0.03mm, and require on the whole large plane without milling cutter to connect the cutter section poor.Because the fixed form material is spheroidal graphite cast-iron QT450-10, can't eliminate fully all the time that trickle on the large plane to connect the cutter section poor, the horizontal accuracy the when equipment that has influence on is installed fixedly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing method that the large plane of fixed form connects little section difference of cutter of eliminating, and can eliminate effectively that to connect the cutter section poor, guarantees the level and smooth light on large plane, and feel is poor without section.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind ofly eliminate the processing method that the large plane of fixed form connects little section difference of cutter, may further comprise the steps:
Step 1: select the four-axle linked horizontal boring-milling center of high accuracy, and adopt Cutterhead and blade;
Step 2: rough mill: distribute and rough mill cutting output, minute two cuttves processing, the first cutter is rough milled 6mm, and the second cutter is rough milled 3mm, and cutting linear velocity is 95~105m/min;
Step 3: half finish-milling: the residual 0.05mm of half finish-milling, cutting linear velocity are 115~125m/min;
Step 4: finish-milling: finish-milling light face 0.05mm, cutting linear velocity is 190~210m/min.
As preferably, adopt one-way feed, from lower to upper feed in the described step 4 during finish-milling.Avoided back and forth two-way or added from top to bottom producing the cutter that shakes that resistance causes man-hour.
As preferably, the cutting linear velocity of rough milling in the described step 2 adopts 100m/min.Avoided because cutting the too fast tool damage that causes.
As preferably, the cutting linear velocity of half finish-milling adopts 120m/min in the described step 3.Because cutting output reduces, promote cutting speed, in the situation that guarantee that cutter does not damage, improved production efficiency.
As preferably, the cutting linear velocity of finish-milling adopts 200m/min in the described step 4.Cutting speed increases substantially, and has improved operating efficiency, has guaranteed the uniformity on plane.
Beneficial effect:
The present invention adopts technique scheme that a kind of processing method that the large plane of fixed form connects little section difference of cutter of eliminating is provided, and has eliminated effectively that to connect the cutter section poor, has guaranteed the level and smooth light on large plane, and feel is poor without section.
The specific embodiment
A kind ofly eliminate the processing method that the large plane of fixed form connects little section difference of cutter, may further comprise the steps:
Step 1: select the four-axle linked horizontal boring-milling center of high accuracy, and adopt Cutterhead and blade;
Step 2: rough mill: distribute and rough mill cutting output, minute two cuttves processing, the first cutter is rough milled 6mm, and the second cutter is rough milled 3mm, and cutting linear velocity is 95~105m/min;
Step 3: half finish-milling: the residual 0.05mm of half finish-milling, cutting linear velocity are 115~125m/min;
Step 4: finish-milling: finish-milling light face 0.05mm, cutting linear velocity is 190~210m/min.
Adopt one-way feed in the described step 4 during finish-milling, from lower to upper feed has effectively solved back and forth two-way or has added from top to bottom and produced the cutter problem of shaking that resistance causes man-hour.The cutting linear velocity of rough milling in the described step 2 adopts 100m/min.The cutting linear velocity of half finish-milling adopts 120m/min in the described step 3.The cutting linear velocity of finish-milling adopts 200m/min in the described step 4.Eliminated effectively that to connect the cutter section poor, guaranteed the level and smooth light on large plane, feel is poor without section.
Specific embodiment described herein only is to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or replenish or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
