Dimensional changes in wood.
To compensate for small dimensional changes in assembled components.
Dimensional changes of less than 8μm over time in a wide machining range(actual data with room temperature change of 8°C[TAS-C applicable]).
Reduction of warping tendency and dimensional changes(during or after processing).
DIL 832 dimensional changes are detected and measured by an incremental optical encoder with a true resolution of 1 nm.
Low coating temperatures avoid shape or dimensional changes and the need for finishing work.
Machining dimensional changes over time from thermal deformation are also minimized with Okuma's unique Thermo-Friendly Concept.
Also, superior brilliance, stable hardness and small dimensional changes are its characteristics.
Dimensional changes over time are extremely low and thermal expansion/dimensional reproduction related to changes in temperature are very good.
However, that all happened in order to make those dimensional changes and have a balancing take place.
In the DIL 831, the dimensional changes are detected and measured by an innovative incremental optical encoder with a true resolution of 1 nm.
When both the above-mentioned characteristics and this limitation are considered, the dimensional changes caused by moisture and water absorption are not significant in general.
These dimensional changes open gaps between the blade tips and the casing in gas path systems and between the seal and housing in labyrinth seal systems.
In rotating equipment such as compressors, gas turbines, and turbochargers,thermal and mechanical operational effects cause dimensional changes between the rotor and stator.
Use of the Thermo-Friendly Concept makes it possible to keep dimensional changes to within 10 μm in room temperatures changes up to 8°C, maintaining stable machining accuracies over long times.
In addition to being highly heat-resistant with a continuous service temperature range of 200 to 240°C, PPS(polyphenylene sulfide) has chemical resistance comparable to fluororesins as no organic solvents can dissolve it at temperatures of 200°C and below,and undergoes virtually no dimensional changes from hydrolysis and water absorption the way polyamide does.
However, since polyamide is susceptible to strength degradation from hydrolysis and dimensional changes from water absorption, designers find it to be a very challenging material to use.
In contrast to humidity, dimensional changes brought about by fluctuations in temperature are extremely minimal and would pose almost no threat by themselves, which is not surprising given how few of these materials would be expected to appreciably swell or contract due to temperature alone.
Due to the increased tendency of polyimides to absorb moisture, it is advisable to seal theseparts with a vacuum barrier film to avoid dimensional changes to ensure very high quality and should be opened just before use.
When machining under changing ambient temperatures, machining dimensional changes are affected by expanding/contracting machine components as well as workpiece position with respect to the table in machining centers and workpiece size in lathes.
Realization of a powerful and rational structure based on sophisticated strength calculations, andapplication of Okuma's original Thermo-Friendly Concept to minimize machining dimensional changes over time that result from thermal deformation, enables highly efficient machining of large bearings or large-diameter flange-shaped parts.
Thermo Active Stabilizer- Construction(TAS-C) When machining under changing ambient temperatures,machining dimensional changes are affected by expanding/contracting machine components as well as workpiece position with respect to the table in machining centers and workpiece size in lathes. TAS-C, based on machine thermal characteristics, with appropriately placed temperature sensors and feed axis position data, will predict and accurately control thermal deformation in machine construction when ambient temperatures change. .
Machining power of 45 kW is achieved over the entire machining area. Moreover, with the Thermo-Friendly Concept,machining dimensional changes over time are one-fourth those of the previous machine, less than 20 μm(room temperature change of 8°C) over the entire machining area on the table.
The Thermo-Friendly Concept serves to maintainstable machining accuracy over long times with dimensional changes kept to within 10 μm as ambient temperaturechanges 8°C. Also available are the OSP-P300S with"Easy Operation" and the Collision Avoidance System that give users both good machining performance and ease of use.
Machining dimensional change over time of ø17 μm(LB35Ⅲ actual data).
Machining dimensional change over time 1/2(compared with previous model).
Please tell me about dimensional change of aluminum products after alumite treatment?
Figure 6-12: Dimensional change resulting from heat treatment.
Causes for dimensional change in S and E are described below.
With little or no dimensional change with processing temperatures of 60°C(and less than 5% dimensional change even at 100°C for 5 minutes).
