Overview :

In today’s competitive market, you need rodust CNC turning centers with un-copromised performance and specifications to produce world class products quickly accurately and with minimum non productive time LARGE Series is really a feather in the cap for Macpower since it gives rigidity and performance to the optimum level.

Structure & Frame :

The rigid base and 45° slant bed are made out of 25 grade cast iron for more stability. It is heavily ribbed to provide rigidity and least distortion during heavy cuts and faster production, with virtually no vibration. Structure also facilitate easy chip flow.

Tailstock :

The tailstock consists of a hydraulically operated quill, which moves inside the housing. The quill and body are independently moveable. The tailstock is supported on V and flat guide ways. Programmable quill is provided as a standard feature

Carriage Assembly :

X and Z Slide are mounted on precise four circuits linear motion blocks with high load carrying capacity, designed to support increased acceleration and deceleration rates as well as cutting pressure.

Guarding :

Equipped with the advantage of an ergonomic design. The machine comes with a full guard that enables a clean premise throughout the operation. These features prevent contamination being spread on to machine slides, switches and other electrical devices.

Spindle :

The spindle is of cartridge type design and uses 3 super precision angular contact bearings at front and 2 angular contact bearings at rear end. The bearing configuration gives high stiffness to the spindle assembly in both axial and radial direction.

Precise Linear Guideways :

All axes are furnished with precise and heavy load capacity re-circulating ball guide ways enabling high acceleration-de acceleration and hence batter productivity

Double-Anchored Ball Screws :

Ball Screws are directed by direct coupled AC servo motor with flexible coupling. This greatly improves positioning accuracy, and provides more accurate threading and contouring. Ball Screws are anchored at both ends and inspected for parallelism with axis guide. Pre-loaded ball nuts eliminate backlash.

Turret :

Bi-directional turret in either direction for minimum possible induction time they are robust and completely enclosed with complete lubrication

Advance Inspection Technology :

Laser Calibration is carried out to insure the linear accuracy, providing accurate compensation for pitch and backlash. The machine facilities the attainment of positional accuracy up to 0.010 mm / 300 mm and repeatability accuracy up to 0.007 mm.
