Product Description

Double Column Series are longitudinal by hydraulic, cross feed axis and vertical axis by AC servo motors.

Product Feature

Optimized Structure

All major parts are manufactured from high tensile cast iron, tempered and stress relieved for best rigidity and stability. Structural parts are rib reinforcement for outstanding rigidity.

Precision Spindle Design

The spindle runs in a class P4 high precision angular contact bearing, assuring run-out accuracy in 2 μm. The cartridge-type spindle is completely sealed and lubricated for long working lifetime, providing high accuracy grinding and a long service life.

Turcite-B on Slideways

The X slideways is coated with Turcite-B for stable movement and long term accuracy.

M.P.G. Handwheel

The Cross & Vertical feed controlled by an M.P.G. handwheel instead of a conventional handwheel. Feed is drivn by an AC servomotor for effortless operation and high accuracy.

Heavy Duty Linear Guide Ways on Cross feed

Slant beam construction. This provides outstanding load distribution on the entire beam surface, assuring maximum stability during heavy duly grinding. The beam surface is equipped with two heavy duty linear guide ways with great span for extra smooth movement and high rigidity.

Precision Feed on Vertical axis

The vertical axis is equipped with high precision, preload linear guideways combined with high precision ball screw transmission, assuring outstanding feed accuracy and maximum stability.

Variable Table Speed

The variable feed speed is controlled by a proportional hydraulic valve, allowing for feed speed adjustment according to the workpiece type for increased convenience of operation.

Automatic Circulated Lubrication System

The entire machine is lubricated by an automatic circulated lubrication system. It provides lubrication to all slideways and transmission parts, ensuring high accuracy and long service life.

NC Auto Down Feed System (AD5 type)

NC auto down feed system (AD5) is standard, to greatly increasing operational convenience.

NC Auto Parallel Dressing & Compensating System (Option)

The optional NC auto parallel dressing & compensating system is available to equip with an optional NC auto down feed system (AD5 type), greatly increasing the grinding efficiency.
