Turning
Parts:
Turning the workpiece in a lathe using the
method of cutting tool rotation processing workpiece. Turning processing
cutting is mainly composed of workpiece and not provide tools. Turning is the
most basic, the most common method of cutting, occupies a very important
position in the production. Turning for processing rotary surface, a large part
of workpiece with rotating surface turning method of processing can be used,
such as the external cylindrical surface, inside and outside the cone face, face,
groove, screw and rotary forming surface, the tool is mainly used tools.
Turning precision is generally it11-it7, some can reach IT6, surface roughness
Ra 12.5-08um. can be achieved by Turning Parts, we call turning parts, there
are many kinds of turning parts, most famous is via hard turning to maintain
the thermal stability of the parts.
Category:
Based on different facilities(CNC facility)
to do the turning process,CNC turning parts included Lathing Parts,milling
parts,Grinding Parts;
Basically,we can realise it on different
raw material,like copper alloy,steel,and aluminium alloy.
Concerned
Factors:
(1) The biggest problem is to use or
without cooling liquid. For interrupted cutting parts such as gears, the best
use of "dry turning", otherwise the thermal shock feed and withdrawal
knife is likely to cause the blade to rupture. As for the continuous cutting
knife head, high temperature produced in dry turning process to toughening
(softening) the pre cutting area, thereby reducing the hardness of the material
to make it easy to cut. This phenomenon shows that the stem cutting speed
increase is good. At the same time, no coolant cutting method has obvious cost
advantages. (2) Layer whitening whitening scald layer (heat affected zone)
"may be a dislike to appear in hard turning and grinding operation, namely
in the material surface to form a layer of invisible to the naked eye is very
thin (typically 1 m) crust. The formation of albino layer in the hard turning
process, usually because of blade Passivation causes too much heat to the inner
parts. Often whitening on bearing steel form, and it is very harmful to the
bearing ring like need to withstand high contact pressure parts, with the
passage of time, the albino layer may stripped and lead to bearing failure.
(3) Machine:stiffness determines precision
hard turning. Nearly 15 ~ 20 years of manufacturing machines in the almost all
have good rigidity, enough to withstand hard turning. In many cases, the
overall condition of the machine is largely over the use of life is more
important, the general maintenance The opening of the bed can also be used for
hard turning. In order to increase the rigidity and damping characteristics for
hard turning machine, hatey characteristics of many advanced machine tool for
the machining center, including polymer composites reinforced with a spring
clip (the spindle support near the workpiece) is directly matched with the
spindle and hydrostatic guideway system. The maximum rigidity means a tool to
reduce vacant, and extending parts out, and cancel the adjustable gap plate and
gasket, its goal is to keep all parts as close as possible to the turret.
(4) Process:because of the heat generated
by hard turning most chips away, before and after the processing of chip
inspection You can find the whole process is coordinated. Continuous cutting,
the chip should be blazing orange, and like a ribbon like flowing out. If the
chip after cooling by hand pressure fracture, shows that cutting heat is
normal.
(5) Blade:cubic boron nitride (CBN) inserts
the price is expensive, but the most suitable for the hard cutting blade
CBN.Cbn blade can keep unchanged in the positioning of intermittent cutting
process, to provide a safe tool wear rate in continuous cutting process. When
using the hard turning process reasonable, except in the control of CBN blade
diameter tolerance is not better than grinding, other properties are second to
none.
