YKD2280数控弧齿锥齿轮铣齿机
YKD2280 CNC SPIRAL BEVEL GEAR GENERATOR
一．机床用途及使用范围
YKD2280型机床为精密数控弧齿锥齿轮铣齿机，可用于加工直径800毫米，模数15毫米范围内的各种格里森齿制的弧齿锥齿轮、准双曲面齿轮和等高齿齿轮。
本机床刀具装在摇台上（圆导轨），该结构整体刚性强，工作平稳，精度高。亦可用于硬齿面刮削，该摇台结构式齿轮机床经久耐用，正常使用寿命可达数十年。
本机床的性好，适合大批量生产粗、精加工中、重型卡车、矿山机械、工程机械、船舶齿轮。
本机床采用西门子828D数控系统和交流数字伺服系统，具有三个数控轴：工件（Y轴）、摇台（X）轴、床鞍（Z轴），可实现三轴联动，刀具主轴（S轴）采用交流变频调速，使机床无需改变任何挂轮可实现切削运动，操作更方便，柔性强，使只具有机械铣齿机操作调整经验的人员能将常用的YT2250（或Y225）、Y2280等机床调整卡的有关参数转换为本机床的相应参数使用。
二．机床主要特点：
采用交流变频电机作主驱动动力源，而摇台和工件主轴都由伺服电机驱动，床鞍进给由伺服电机通过滚珠丝杠驱动，简化了传统的机械结构，无需更换挂轮减少了机床调整时间，缩短了传动链，不但提高了机床精度，而且使操作更为准确、方便。本机床可配置安全防护罩和自动排屑器。机床的密封电气控制柜可配置空调。

Ⅰ. Applications of Machine
Model YKD2280 machine is a precision CNC Spiral Bevel Gear Generator, which is designed for roughing and finishing Spiral Bevel Gears and Hypoid Gears ａnd Equidepth gears of the Gleason system with the diameter up to 800mm and module 15mm.
On this machine, the cutter is mounted on the cradle (circular guideway). The integral structure is rigid, highly accurate ａnd working stably. The cradle-type gear cutting machine, which is also possible for hard surfacing, is durable and the service life will be several dozens of years under normal operating conditions.
The machine is with universal features and it is suitable for roughing and finishing, in mass production, gears used for medium & heavy load trucks, mining machineries, construction machineries and shipbuilding industry.
The machine is equipped with a CNC control system 828D (SIEMENS) and designed to operate as a three-axis machine, i.e. cradle rotation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by the CNC control system to cut gears. The rotation of cutter spindle (S axis) is controlled by an A.C. frequency-variable motor for its stepless control. Therefore, no change gears will be used on the machine for cutting gears. The machine operation is easy and flexible. The clients who have the conventional machines can convert the machine settings used for YT2250 (or Y225) and Y2280 machines into the machine settings for the YKD2280 machine.
Ⅱ. Main Features of Machine
An A.C. frequency-variable motor is used as a main driving power source while the cradle rotation ａnd work spindle rotation are driven by the servo motors. The sliding base movement is driven by a servo motor through a ball screw. All of these features of the machine are for the purpose of simplifying the conventional mechanical structure, reducing the machine setup time and shortening the transmission train because of the change gears elimination. In this case, not only the machine accuracy is increased, but also the operation is easy and convenient. Safety guards and an automatical chip conveyor may be provided on the machine. The machine is equipped with a sealed electrical cabinet which is with an air conditioner.
