機床沒有保質期 哈哈 只有保修期 過了保修期 如果當地有該品牌的服務團隊 只要不是大毛病 免費也是很正常的 一般保修期都是一年 過了一年之後 系統肯定不保修 需要維修一般都得交維修費的

Ⅲ 求人幫我翻譯一下這段機械類的專業英語 謝謝

有2種類型的光電測量系統，根據規模的光罩。首先，如果掃描光罩是磁碟，測量設備被稱為一個旋轉編碼器或只是一個編碼器。旋轉編碼器可用於angu-lar測量旋轉運動，如數控回轉軸，傾斜角測量或計量表。另一方面，如果掃描標線是線性刻度，測量設備是以線性編碼器或簡單的線性表。線性和旋轉編碼器可分為絕對和相對編碼器。絕對式編碼器使用規模畢業形成幾個刻度或代碼跟蹤每一個可能的位置創建一個獨特的代碼。因此，位置是直接讀取和有沒有需要找到一個參考位置。相對編碼器採用恆定光柵周期表，和位置測量相對於參考位置。該決議的相對編碼器的絕對值高於，是最典型的測量裝置的高精度的機床。

該決議的相對編碼器主要取決於期間的光柵尺。較小的期間的光柵結構的高解析度。此外，測量精度取決於安裝包容之間的掃描和刻度標線。實際上，典型的光柵周期小於20μ米，高精度應用，有線性編碼器4μ米光柵周期。此外，掃描光罩可以分為不同的掃描網格偏移有2種光電測量系統，根據規模的光罩。首先，如果掃描光罩是磁碟，測量設備被稱為一個旋轉編碼器或只是一個編碼器。旋轉編碼器可用於angu-lar測量旋轉運動，如數控回轉軸，傾斜角測量或計量表。另一方面，如果掃描標線是線性刻度，測量設備是以線性編碼器或簡單的線性表。線性和旋轉編碼器可分為絕對和相對編碼器。絕對式編碼器使用規模畢業形成幾個刻度或代碼跟蹤每一個可能的位置創建一個獨特的代碼。因此，位置是直接讀取和有沒有需要找到一個參考位置。相對編碼器採用恆定光柵周期表，和位置測量相對於參考位置。該決議的相對編碼器的絕對值高於，是最典型的測量裝置的高精度的機床

Ⅳ 何謂數控機床的控制介質

怎麼說呢，目前我國的數控機床屬於低端，若看客覺得不舒服，那我換個說法，中低端咋樣。我國的數控品牌設備，所謂的自主研發，系統上絕大部分是仿照FANUC和三菱，甚至西門子國內還沒有仿造的（或許是小的見識短淺，沒看到），機械部分只是采購國際品牌的零部件進行組裝，在宣傳樣冊上，標注的精度和關鍵零部件或許和進口設備一樣，或者還要高，但在使用壽命，剛性，尺寸穩定性，還是有相當大的差距的。我國目前數控行業發展的方向就在走價廉的路線（物美咱先放到一邊哈），其實用的零部件真心不錯，只是關鍵零部件大部分國內廠家沒有自主的研發，買個台灣的主軸，加上個德國的齒輪箱，換上義大利的刀塔，再買套日本的系統，拼起來就出售，看似國際的知名品牌，但是組合起來的效果確實不咋樣。
