Overview
The Sharp SV-5128 ST vertical machining center is engineered to have unsurpassed quality and outperform all other machines in its category. This is an extremely rigid “C” frame design using hardened and ground box ways. It has an extra long cross travel (27.5”) that allows large work piece to be machined in one set up. All structural components are made of Meehanite casting with internal ribs running throughout each section. Precision hand scraping of each section provides near perfect alignment assuring long term accuracies.
- FANUC Oi-MD, 10.4” LCD color screen
- Travel X/Y/Z: 51.2” / 27.5” / 24”,
- Table: 59” x 25.6”
- Hardened and ground box ways
- Spindle: 10K RPM, CAT 40 Big Plus, Belt Driven, 25 HP Motor
- ATC: Side mount 24 Tools
- Positioning Accuracy X/Y/Z: (+/-0.0002”)
- Machine size w/o Chip Conveyor: W/D/H (126” / 111” / 122”)
- 4 guide ways are induction hardened and then precision ground
- Each axis is driven by a high precision double-nut ball screw that is centered between the guide ways.
- The ball screws are pretensioned and anchored at both ends with angular contact bearings. Ball screws using single nuts or ones that are not pretensioned will have much greater play and backlash which can lead to problems with chatter and accuracy
Features

Precision through Craftsmanship and Technology
Structural mating surfaces are precision hand scraped to increase the flatness and to improve geometric accuracy (straightness and squareness) of the whole assembly. This provides near perfect alignment assuring long term accuracy.
