KE55

Vertical Machining Center Makino KE55

Introduction

A key issue on the shop floor today is how to machine small parts and with high accuracy. Backed by the latest in mechanical and electronic technology, the operator-friendly KE-55 represents the next generation of operations, including oblique and circular cutting as well as tapping, can be executed accurately without using attachments or worrying about centring. As a result, operators are freed from troublesome setup world, allowing them to concentrate on their main job-machining. When producing single part runs, the KE-55 out-performs the competition in every aspect, including speed, accuracy and machining reliability.

STRUCTURE

Innovative Machine Construction
The machine proper continues Makino’s proven ram and knee type design that allows superior accessibility. X and Y axis travels in the ram and Z axis travel in the knee provided by the innovative axis design. Because the tool moves exactly as indicated on the part drawing. Machining operation are easy to understand and operate

 
Superb Accuracy Assured By Square Guideways
Guideways are bonded with Turcite B to create a smooth sliding surface. Square guideways and double end gibs assure superb accuracy. An automatic lubricant supply system works to assure long hours of smooth operation.

USER FRIENDLY

User Operation
Dual mode (CNC and Manual) is able to allow school to teach both conventional machining and also CNC machine. ’2′ in ’1′. Therefore, the institute is able to reduce the conventional mill required and so as the class room. Every thing is able to maximize.
 
The only choice to treasure the operators skill & CNC power
 
PERFECT BALANCE BETWEEN MAN AND MACHINE COORDINATION
