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 phi160 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) finely milling: finely 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
Technical field
The present invention relates to field of machining, be specifically related to a kind ofly eliminate the processing method that the large plane of fixed form connects cutter micro-section of difference.
Background technology
Fixed form is the firm banking for installing during nuclear power generating equipment, high to the required precision of large plane, and the flatness form and position tolerance of large plane is 0.03mm, and require in whole large plane without milling cutter to connect cutter section poor.Because fixed form material is spheroidal graphite cast-iron QT450-10, cannot eliminate that trickle in large plane to connect cutter section poor completely all the time, have influence on horizontal accuracy when equipment is installed fixing.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of eliminates the processing method that the large plane of fixed form connects cutter micro-section of difference, effectively can eliminate that to connect cutter section poor, and ensure the level and smooth light of large plane, 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 cutter micro-section of difference, comprises the following steps:
Step one: 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, point two cutter processing, 6mm rough milled by the first cutter, and 3mm rough milled by the second cutter, and cutting linear velocity is 95 ~ 105m/min;
Step 3: half finish-milling: half finish-milling remains 0.05mm, cutting linear velocity is 115 ~ 125m/min;
Step 4: finish-milling: finish-milling light face 0.05mm, cutting linear velocity is 190 ~ 210m/min.
As preferably, in described step 4, during finish-milling, adopt one-way feed, from lower to upper feed.Avoid back and forth two-way or add the cutter that shakes producing resistance man-hour and cause from top to bottom.
As preferably, the cutting linear velocity rough milled in described step 2 adopts 100m/min.Avoid because cutting the too fast tool damage caused.
As preferably, in described step 3, the cutting linear velocity of half finish-milling adopts 120m/min.Because cutting output reduces, promoting cutting speed, when ensureing that cutter does not damage, improve production efficiency.
As preferably, in described step 4, the cutting linear velocity of finish-milling adopts 200m/min.Cutting speed increases substantially, and improves operating efficiency, ensure that the uniformity of plane.
Beneficial effect:
The present invention adopts technique scheme to provide a kind of and eliminates the processing method that the large plane of fixed form connects cutter micro-section of difference, effectively eliminates that to connect cutter section poor, and ensure that the level and smooth light of large plane, feel is poor without section.
Detailed description of the invention
