Precision raug yog ib qho uas tseem ceeb tshaj txoj kev loj hlob kev taw qhia txog txhua yam raug, nws kuj yog ib lub cim rau ntsuas seb lub High School-tech ntawm ib lub teb chaws. Rau txoj kev siv tshuab cutting-edge thiab cov kws muaj txuj ci kev lag luam yog nyob ntawm precision nrhiav kom tau. Peb koom xab tshuab ua phaj siab npaumprecision xab seev, siv lug ntawm machinery raug, raug ntsuas, kev lag luam hauv, industries aerospace thiab lub teb chaws kws muaj txuj ci. Daim ntawv thov granite hauv peb coordinates xab twb paub tseeb hais tias kom ntxov li ob peb xyoos dhau los. Tsis muaj lwm yam khoom siv uas yog ib qho zoo tshaj granite uas ua haujlwm los ntsuas yuav tsum yog muaj.

Nta:

Kev faib ua feem: 3.07

Elastic modulus: 128Gpa

Compressive zog: 262.2Mpa

Lub zog: 374.8Mpa flexure

Dej haum: nquag 0.5 ~ 0.7%

Kev tawm expansion: 55 coefficient ~ 73 × 10-6℃

Ntug dej hardness: 79.8(Amount to HRC>55)

Zoo:

1. zoo stability. Tom qab ib plhom leej puas xyoo laus tej kev kho mob, kev nyuaj siab nrog muaj lawm eliminated. Cov koom haum no tsis txav chaw, uas yog yuav luag tsis muaj deformation, tus neeg yuav nyob ruaj khov rau ib lub sij hawm ntev.

2. yooj yim ua. Los ntawm kev sib tsoo, polishing, nws yuav yooj yim precision siab thiab roughness deg. Tseem tsis rhiab rau qhov kub thiab txias. Coefficient ntawm thermal conductivity and coefficient ntawm thermal expansion coefficient yog me, txawm nyob hauv ib qho chaw hlakub ib puag ncigyuav muaj neeg. Nyob rau hauv cov khoom precision, cov distortion uas yog kub yuav feem xyuam rau txoj laij. Tiam sis granite muaj tsis rhiab rau qhov kub thiab txias, tiam sis sov yog so, vim li no thiaj ncav precision yooj yim dua.

3. yooj yim nkawm. Nyob rau hauv cov mob los ntawm qhov chaw kom huv, lub granite muaj kuj yooj yim dua, tsis deformation, ces nws yuav tsis muaj feem xyuam rau tus neeg.

4. zoo kev co haum. Kev co yog lwm yam unfavorable txoj kev ntsuas precision.

5. cov-txoj, diamagnetic.
