Overview

The Sharp KMA-CNC series was engineered for easy, simple, hard metal removal. This is an extremely rigid “C” frame design using hardened and ground box ways and 18 speeds gear head spindle to do the cutting. There is no Automatic Tool Change (ATC). This series has 3 sizes equipped with 10,15 HP motor, 1,500 rpm, CAT 50 spindle. Machines weight from 13,000 lbs to 19,000 lbs

Features

4 Box way design

The 4 slide ways are hand scraped, hardened and ground. Box ways have superior vibration damping capacity than linear ways and can be used on severe machining applications. During a crash, they are less susceptible to damage due to large contact surface.

Gearhead High Precision Spindle

The gearhead spindle delivers greater torque output for heavy duty machining. The high quality gears are hardened and ground for durability, high accuracy and minimum noise. The gear box has circulating type filtration system to keep the lubricating oil clean. It has 18 speeds ranges from 45 rpm to 1,500 rpm
