数控钻床和小型加工中心选购指南

数控钻床和小型加工中心是现阶段五金加工中一种重要加工设备，该设备价格相对加工中心价格便宜，有大部份小件加工产品是可以代替加工中心完成零件加工，选用数控机床不但对于操作、工艺设定和维护包括对于生产产品的质量要求都重要。针对这些要求在选购数控机床的数控钻床和小型加工中心有几大方面是需要注意或了解的：

Nc drilling machine and small machining center is an important processing equipment, metal processing the equipment prices relatively cheap processing center, with most of the small processing products can be instead of machining center parts processing, selection of nc machine tool not only for operation, process setting and maintenance including for production product quality requirements are very important. According to these requirements in the choose and buy of nc machine tool nc drilling machine and small machining center has several big aspects need to notice or understand：

1.数控钻床和小型加工中心工作台面的刚性和稳定性。

6.钻床在使用时要注明操作规程：

Drilling machine when use to indicate the safety operation procedures

（1）。同时清理工具，做好机床保养工作。

At the same time cleaning tools, machine tool maintenance

（2）。钻攻小的工件时，要用台虎钳，钳紧后再钻。

When drilling and tapping small artifacts, use your vise, clamp tightly before drilling

（3）。操作前要穿紧身防护服，或围布于身上，防止机器绞伤，不得穿裙子、拖鞋。

To wear tight protective clothing before operation, or throughout the body, prevent the machine from ground, may not wear a skirt, slippers

（4）。机床开动后，严禁戴手套操作，铁屑要用刷子，禁止用嘴吹。

After the machine start, it is forbidden to wear gloves operation to remove iron filings with the brush, blow with the mouth is prohibited

（5）。严禁用手去停住转动着的钻头。

It is strictly prohibited to use hand to stop the rotation of the drill bit

（6）。钻床床面上不要放其他东西，换钻头、夹具及装卸工件时须停车进行。

Don't put anything else on drilling machine bed, bit change, clamp and when loading and unloading workpieces must stop

（7）。开车前应检查机床传动是否正常、工具、电气、防护装置。

Should check whether the machine tool drive is normal before driving, tools, electrical, safety protection device

（8）。带有毛刺和不清洁的锥柄，不得装入主轴锥孔，装卸钻头要用楔铁，严禁用手锤敲打。

With burr and don't clean the taper shank, shall not be loaded into the spindle taper hole, loading and unloading drill with wedge iron, it is forbidden to use hammer knock

（9）。工作完毕后，应切断电源，卸下钻头，主轴箱靠近端，将横臂下降到立柱的下部边端，并刹好车，以防止发生意外。

After the completion of work, cut off power supply, the drill bit, spindle box must be close to the end, will fall to the bottom of the column beam end, and brake the car, in order to prevent the accident
