MIAN FEATURES

The model YKA4220 is a 2-axis controlled plunge-in-cut gear shaving machine of novel design and unique structure arrangement. The machine is featured in fixed work position, excellent rigidity, constant working accuracy, nice adaptability and versatile functions. It is designed and manufactured according to ergonomics principle, and its shaving operations are comtrolled by a computer and displayed on a CRT. Integrated with the function of self trouble diagnosis, it is a new generation gear shaving machine of high precision, high efficiency and high automation.

Main performances:

The model YKA4220 is specially designed for performing plunge-in-cut gear shaving operations. When a proper cutter is used, the machine is able to shave crowned gear and little tapered gear. It is able to implement continuous shaving operations from roughing go finishing, and the shaving cutter can be moved back by a microfeed. The machine is automatically lubricated at regular intervals and the workpiece is clamped and released automatically. The machine is automatically lubricated at regular intervals and the workpiece is clamped and released automatically. The machine is equipped with an automatic chip conveying mechanism.

Main features:

The vertical guideways (Z axis) are inserted with steel strips and coated with teflon.

The primary motion of the machine works at an infinitely variable speed.

The main drive is transmitted to the cutter via the universal joint of equivalent angular velocity and the roll spline shaft. Only one pair of gears is adopted for the whole transmission chain, which ensures the machine’s smooth running and low noise

Reliable pre-loading measures have been taken at the joint area between the cutter head and the vertical slide plate to improve the work rigidity and minimize the error caused by the self weight of the cutter head.

The heated cutting oil runs around the machine bed and then goes back to the oil tank. The hest exchange inside the machine bed has ensured the machine; s thrmal balance and thus further improved its thermal stability.

Either of Mitsubishi system, fanuc system, Num system and Siemens system can be equipped on the machine according to the user’s request.

Command for switching a shaving mode and cutting parameters are all inputted to the computer by the keyboard.

A windrow-type automatic work loading and unloading device can be installed on the machine to realize the automation of a single independent machine. Two different types of workpieces can also be put together on the loading device for an automatic cutting operation.

The machine is fully enclosed to prevent the cutting oil from splashing out so as to create a clean work area.
