YK2212B數控弧齒錐齒輪銑齒機

Ⅰ．機床的主要用途

本系列機床集我廠多年研究開發弧齒錐齒輪銑齒機床及數控技術應用經驗，采用現代設計方法和機電一體化技術而研制的新型數控弧齒錐齒輪銑齒機。

本系列機床特別適用于加工小型減速機行業、摩托車及自行車行業中小規格弧齒錐齒輪及準雙曲面齒輪，同時也更適用于高檔電動工業縫紉機及電動工具等行業的小模數弧齒錐齒輪及準雙曲面齒輪。于成批生產，也可用于大量及單件小批生產，組線方便、操作簡便、穩定可靠。

Ⅱ．機床主要性能和結構特點

1．本系列機床系三軸數控弧齒錐齒輪銑齒機，即搖臺回轉（X軸）、工件主軸回轉（Y軸）、床鞍進給（Z軸）三軸聯動完成銑齒運動，刀軸的旋轉由主軸伺服電機控制，實現無級調速，噪聲低。

2．本系列機床調整方便，可根據不同切削方法的要求，對滾切、分齒、切深進給、銑刀轉速、搖臺正反向進行程序設定，同時可大大提高機床加工效率。

3．本系列機床用電子手輪對刀、調刀。Z軸設有軟、硬二重極限保護，具有安全保護功能。

4．機床搖臺傳動采用高精度圓柱齒輪副，工件箱傳動采用高精密蝸輪副傳動，運動平穩，保證了搖臺結構的高動態剛性，高速、高效及分齒傳動的高精密性，切齒精度均可穩定達到GB6級。

5．本系列機床采用德國西門子（SIEMENS）公司828D系統，同時根據用戶要求可配置日本法那克（FANUC）公司的數控系統，實現機床的自動循環控制、手動控制及故障診斷。

6．本系列機床具有獨立、密封的電氣控制柜，并配置空調。

7．本系列機床配置安全防護。

Ⅰ．Main Applications of Machine

These are a new series of CNC machines produced on the base of our experiences for developing spiral bevel gear generators and application of CNC technology in many years, with modern design method and integrative technology of mechanics and electronics.

This series of machines are suitable for cutting small size spiral bevel gears used for small size speed reducer, motorbike ａnd bicycle industries, ａnd for cutting fine spiral bevel gears used for top grade sewing machines ａnd power tools. It is most suitable for batch production as well as suitable for mass or jobbing production, The machine is easy for operation and the quality is stable and reliable. It’s convenient to arrange the production line.

Ⅱ. Main Performances and Structural Characteristics of Machine

1．This series of machines are designed to operate as three-axes CNC control spiral bevel gear generator, i.e. cradle roll (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by control system for cutting the gears. The rotation of cutter spindle is controlled silently by a servo motor for its stepless control..

2．This series of machines are easy to adjust, with setting up the procedure for generating, indexing, infeed, cutter speed and cradle return roll according to requirements of different cutting method, meanwhile the productivity of machine has a great increase.

3．Tool setting and adjustment of the machines are made through an electronic handwheel. There are soft & hard limits on the machine for the protection functions.

4．A high precision cylindrical gear pair is used for the cradle movement and the workhead is driven by means of a high precision worm and worm wheel pair. The smooth transmissions ensure the high dynamic rigidity of the cradle mechanism and high precision of high speed, high efficient indexing motions. The cutting accuracy of gears can reach Grade 6 of the GB Standard stably.

 5．This series of machines are equipped with CNC control system 828D (SIEMENS) or FANUC CNC to accomplish the automatic or manual control and fault diagnosis.

6．This series of machines are equipped with an independent close type electrical cabinet with an air conditioner.

7．An enclosure and an auto-chip conveyor can be available on this series of machines.
