HANDLING AND INSTALLATION OF THE TX7+
TX7+的搬运和安装
1. 简介 Introduction
我们向尊贵的客户提供此现场准备指南以确保您能迅速安装完毕 ANCA 的TX7+机
床并在最短的时间内开始生产。
These site preparation guidelines are provided to our valued customers,
in order to ensure that the installation of your ANCA TX7+ is
accomplished promptly, and is ready for production within the shortest
time frame.
2. 现场选择指南 Site Selection Guidelines
在安装期间，须检查以下各方面以确保高精确度和性能。
At installation, the following points should be checked in order to
ensure high accuracy and performance.
安装现场应尽量远离任何振动源，如冲压/压制设备，或者刨床类机床。
The installation site should be far as possible away from any sources of
vibration, i.e. stamping/press equipment, or planar type machine tools.
应避免与高频发电机，放电机或电焊机连在同一配电板，这样引起的干扰有可能导
致计算机数控系统产生故障。
Attaching high-frequency power generators, electric discharge
machines or electrical welding machines to the same power board
should be avoided, this should be avoided as interference may cause
the CNC to malfunction.
理想的操作环境要求周围环境的温度为 20°C (68°F)，湿度在 40% 到75%之间。
The ideal operating environment calls for an ambient temperature of
20°C (68°F) with humidity between 40% and 75%.
和所有高精度磨床一样，热膨胀会影响 TX7+的精确度。为了保持静态下的磨削精
度并优化性能，TX7+应安装于不易受气流影响的区域。厂区不一定需要安装空调系
统，但建议周围环境的温度应在 17°C (62.5°F) 到25°C (77°F)之间。12 小时内的温
差应小于 2 °C。这样可以将磨床的热膨胀减小到最低程度。
As with all precision grinding machines the accuracy of the TX7+ can be
affected by thermal expansion. In order to maintain static grinding
accuracy and optimum performance, the TX7+ should be installed in an
area, which is not largely affected by airflow. Air conditioning of the
factory area is not essential, but an ambient temperature between 17°C

TX7+现场准备手册 TX7+ Site Preparation Manual
6
(62.5°F) and 25°C (77°F) is recommended. The temperature should be
maintained consistently between +/- 2 °C deviation over a 12-hour
period. This will minimize thermal expansion on the grinder.
当周围环境的温度超过 30°C 时，应考虑使用冷却液冷却装置，为达到较高的精确
度，冷却液的温度应与周围环境的温度保持一致。
A chiller unit for the coolant should be considered where ambient
temperatures exceed 30°C, for greater accuracy the coolant
temperature should be maintained at ambient temperature.
3. 地基要求 Foundation Requirements
TX7+应安装于坚固平坦的钢筋混凝土地面，厚度应超过 150 毫米（6英寸）。
The TX7+ should be mounted on a flat solid foundation of
reinforced concrete of at least 150mm (6”) in thickness.
地基处应与地面其他区域隔离。
The foundation should be separate from the rest of the floor.
4. TX7+的置放 Placement of the TX7+
TX7+抵达时，应固定于一托板上。托板尺寸为长 2900 毫米，宽 2300 毫米。机床和
托板的最大高度约为 2700 毫米。总重量（机床＋托板＋附件）约为 7500 公斤。木
质托板和 TX7+只可使用叉车从前方（即 B面）进行升降。请参考图 0。
The TX7+ will arrive fixed to a wooden sled. The size of the sled is
2900mm (length) x 2300mm (width). The maximum height of the M/C
