眾所周知，數控開料機不止質量要過硬，后期的使用中以及使用后的保養也尤為重要。很多操作手對保養并不熟悉，日常的一些習慣也往往存在誤區，長時間下來，往往對設備造成了損傷，維護保養，除了對機械、電氣設備的檢查、調整、緊固以外，重要的工作就是潤滑。下面介紹一下數控開料機，封邊機等機械設備潤滑保養中的的常見誤區。

　　1、盲目添加要出事

　　潤滑并不是這么簡單，它是綜合運用流體力學、固體力學、材料學、應用數學、物理化學等基礎理論，來研究潤滑原理、潤滑材料和潤滑方式，控制有害摩擦、磨損的一門科學，加油僅僅是潤滑之中的一環而已。

　　一臺設備的潤滑，其實從它的設計階段就開始了，并且貫穿于整個設備使用壽命始終。

　　2、過量添加 弊大于利

　　事實并非如此，簡單地說，人們把潤滑油加到兩個摩擦表面之間，目的是在兩個摩擦表面形成薄薄的油膜，避免直接接觸，從而減少磨損。

　　但是，考慮到加潤滑油的某些副作用，就必須嚴格控制加油量，例如在減速器中，為了減少齒輪運動中阻力和油的溫升，浸入油的齒輪深度以1～2個齒高為宜，轉速高的加油量還應少些。

　　3、隨意加油使不得

　　設備潤滑油的選擇，根據機器的工作條件、工作環境、摩擦表面具體特點和潤滑方式的不同，選用的潤滑油的種類、牌號也不相同。

　　轉速高、形成油楔作用能力強的設備，應選用粘度低的潤滑油;設備摩擦表面單位面積的負荷大時，應選用粘度大、油性較好的潤滑油;

　　設備工作環境溫度較高時，應采用粘度較大、閃點較高、油性較好、穩定性較強的潤滑油或滴點較高的潤滑脂;

　　設備摩擦表面之間的間隙越小，選擇潤滑油粘度應越低;摩擦表面越粗糙，選擇潤滑油粘度應越大，若選擇潤滑脂工作錐度應越小;壓力循環潤滑中，油溫較高，應使用粘度較大的潤滑油。

　　不同型號的數控開料機的潤滑油是嚴格根據上述原則和實驗結果選擇的。一般情況下不能替換使用，如果任意替換使用就會破壞設備潤滑環境，使機器設備受到磨損，造成經濟損失。

As we all know, not only should the quality of CNC cutting machines be excellent, but the maintenance in later use and after use is also particularly important.Many operators are not familiar with maintenance, and some daily habits often have misunderstandings. Over a long period of time, it often causes damage to the equipment. Maintenance, in addition to the inspection, adjustment, and fastening of mechanical and electrical equipment, the important job is lubrication.The following describes the common misunderstandings in the lubrication and maintenance of mechanical equipment such as CNC cutting machines and edge banding machines.

　　1. Blindly adding will cause an accident

　　Lubrication is not that simple. It is a science that comprehensively uses basic theories such as fluid mechanics, solid mechanics, materials science, applied mathematics, and physical chemistry to study lubrication principles, lubricating materials, and lubrication methods to control harmful friction and wear. Refueling is only one part of lubrication.

　　The lubrication of an equipment actually begins from its design stage, and runs through the entire service life of the equipment.

　　2. Excessive addition does more harm than good

　　This is not the case. Simply put, people add lubricating oil between the two friction surfaces. The purpose is to form a thin oil film on the two friction surfaces to avoid direct contact and thereby reduce wear.

　　However, taking into account some of the side effects of adding lubricating oil, it is necessary to strictly control the amount of refueling. For example, in a reducer, in order to reduce the resistance of the gear movement and the temperature rise of the oil, the depth of the gear immersed in the oil should be 1 to 2 teeth high, and the amount of refueling at high speeds should be less.

　　3. Feel free to refuel

　　The choice of equipment lubricating oil depends on the working conditions of the machine, the working environment, the specific characteristics of the friction surface and the different lubrication methods, and the types and grades of lubricating oil selected are also different.

　　For equipment with high speed and strong ability to form oil wedges, low-viscosity lubricants should be used; when the load per unit area of the friction surface of the equipment is large, lubricants with high viscosity and good oil properties should be used.;

　　When the operating ambient temperature of the equipment is high, lubricating oil with high viscosity, high flash point, good oiliness and strong stability or grease with high drop point should be used.;

　　The smaller the gap between the friction surfaces of the equipment, the lower the viscosity of the lubricating oil should be selected; the rougher the friction surface, the greater the viscosity of the lubricating oil should be selected, and the smaller the working taper of the grease should be selected; in pressure circulation lubrication, the higher the oil temperature, the higher the viscosity of the lubricating oil should be used. Lubricating oil.

　　The lubricants of different types of CNC cutting machines are selected strictly according to the above principles and experimental results.Under normal circumstances, it cannot be replaced. If it is replaced arbitrarily, it will damage the lubrication environment of the equipment, cause wear and tear on the machinery and equipment, and cause economic losses.
