KURAKI Technology

Kuraki's Advanced Technology Results in Superior Machines

SPINDLE DESIGN

• Dual Structure - Long size, large diameter and mass

• Boring spindle and milling spindle rotate together

• Large size bearings in front, center and rear - 3 point support

• Realize large inertia moment (10X more than HMC)

• Tool live = 2X or more

ROTARY TABLE DESIGN

• Standard Full B axis (0.001 degree indexing)

• Large diameter slide ways for Rigidity & High Accuracy

• Hand-scraped slide ways (center and outside)

• Double pinion gear drive (no backlash)

• Kuraki-original mechanical locate pin at every 90 deg. for high indexing accuracy

• Back plates to prevent table lifting motion

• T-style hydraulic table clamp bolts

SPINDLE HEAD AND COLUMN DESIGN

• Box-shaped spindle head and solid column

• Realize a thick column

• Spindle bar is built in thick bearing housing and solid basket shaped spindle head, maintaining rigidity at spindle extension

BED AND SLIDEWAY DESIGN

• Hardening, grinding & wide box ways

• Trapezoid bed with V style rib structure for high rigidity & stability

• Kuraki has 3 different lubrication system based on feed rate & table load

• Scraped connected surfaces of both X & Z axis beds improve rigidity, reduces vibration and Stable X & Y straightness accuracy

FANUC CONTROL

• Fanuc 31i-Model B5

• 15” Color LC

• Centralized pendant panel for both manual and NC operation

• USB memory & CF card interface

• Centralized Pendant

• Mono-lever Type Each Axis Feed Switches

• Portable Manual Pulse Generator

• One-Touch Key Functions (ATC Tool No. Display, Maintenance Display)
