OPTIMAL STRUCTURE DESIGN Equipped with rotary table. The major structural parts are manufactured form Meehanite cast iron, hardened to hardness over HB190 The structural parts are tempered for stress relief that ensures deformation-free performance year after year. X, Y, Z axis are mounted with roller type linear ways, exhibiting extra high rigidity and loading capacity. Oversized column structure dramatically increases machining stability. Fixed column construction.

ROTARY TABLE HIGH ACCURACY The rotary table employs three-piece teeth plate for high accuracy indexing. HEAVY-CUTTING RESISTANCE The three-piece teeth plate combined with hydraulic locking mechanism allows full teeth engagement. This results in higher rigidity and increased heavy cutting capacity.

GEAR BOX This spindle running is transmitted through a gear box, making the machine excellent for heavy cutting applications. With the gear box, the spindle provides two speed changes. The low speed range is 40~1750rpm, and high speed range is 1751~8000 rpm. The wide speed range permits the machine to perform heavy cutting and fine fine finishing. All gears and bearings in the gear box are oil-bath lubricated.

COOLING THROUGH SPINDLE (OPTIONAL) Coolant circulates through spindle offer a direct cooling effect on tools, removing heat that occurs during machining. Combines with filter tank system (optional).

Each Pinnacle machine is subject to dynamic and static accuracy tests. Pinnacle Machine accuracy meets ISO 10791 VDI 3441, ISO 230, JIS B6388 and ASMEB5 standards.

Accuracy

Bi-directional Positioning	A:	0.025	0.003mm
Bi-directional Repeatability	R:	0.015	0.003mm
JIS B6336-4 shows the same value as ISO Standard; P value of VDI / DGQ3441 is equivalent to A of ISO10791-4, and PS is equivalent to R All values shown above are measured for machine in good air conditoned environments.

TWO SCREW TYPE CHIP CONVEYORS ON BASE There are two screw type chip conveyors provided at right and left side of the base. During cutting, the chips are delivered through these chip conveyors for exhausting chips outside of the machine. CHAIN TYPE CONVEYOR (OPTIONAL) The chip conveyor is available to be mounted at the backside of the machine. It removes chips efficiently.

40 TOOLS CHAIN TYPE MAGAZINE (STANDARD) The magazine is driven by a precision cam, featuring fast and accurate tool positioning. Tool selection is bi-directional and random for fast tool change. The magazine accepts ISO40 tool shank. The magazine is separately mounted from the cutting area combined with a protection door to protect tools from contamination from chips or coolant.

HYDRAULIC BALANCE SYSTEM The Z-axis movement is counter-balanced through a hydraulic cylinder. An accumulator is equipped in the hydraulic circuit. This counter-balance system will reduce spindle head vibration to a minimum, while significantly improving machining accuracy.

DUAL PITCH WORM / WORM GEAR SET The transmission mechanism employs high efficiency " Dual Pitch Worm / Worm Gear Set " for increasing teeth engagement percentage. This outstanding feature offers increased efficiency and wear-resistant capability.

HOLLOW BALL SCREW WITH COOLING SYSTEM

Three axes are transmitted through class C3 high precision high speed, no-noise ball screws. Ø36mm, ball screws are pretensioned and preloaded to minimize deformation. A laser unit is applied to calibrate the machine accuracy to ensure machining accuracy. Coolant through ball screws on X, Y, Z axis minimizes thermal deformation and backlash, while ensuring smooth motion during rapid traverse.
