Overview
The Makino MCD2516-5XB is the largest machine in the MCD ultra-precision series, offering expanded travel while maintaining the sub-micron accuracy that defines this product line. The 5XB trunnion configuration tilts the workpiece for optimal chip evacuation and consistent tool engagement, paired with the largest work envelope in the MCD family for handling bigger precision components.
Axis travel of 250 x 150 x 200 mm (9.8 x 5.9 x 7.9 in) on X/Y/Z provides the most generous envelope in the MCD series—66% more X-travel and 33% more Z-travel than the MCD1516. This additional reach accommodates larger mold inserts, multi-cavity tooling, and precision components that exceed the capacity of the smaller MCD variants while still requiring sub-micron accuracy.
The 40,000 RPM HSK-E32 spindle delivers 5.5 kW (7.4 hp), a power increase over the smaller MCD models that enables slightly more aggressive cutting parameters while maintaining finish quality. Positioning accuracy of 0.5 microns with 0.2 micron repeatability continues across the MCD lineup. The B-axis trunnion table tilts through 150 degrees (+120 to -30) with full 360-degree C-axis rotation.
The 250 mm (9.8 in) diameter trunnion table handles workpieces up to 60 kg (132 lb). A 30-tool magazine provides expanded tool storage over the smaller variants. Glass scales, temperature-controlled construction, and advanced thermal compensation are standard. The MCD2516-5XB competes with the Roeders RXP 600 DSC, Kern Micro HD, and Yasda YBM 950V in the precision 5-axis segment for medium-sized components.

Strengths & Limitations
Strengths
- Largest travel in the MCD series (250 x 150 x 200 mm) accommodates bigger precision components while maintaining sub-micron accuracy
- 5.5 kW spindle provides more cutting power than smaller MCD variants for slightly more productive semi-finishing passes
- 30-tool magazine provides 50% more capacity than smaller MCD models for complex parts requiring diverse tooling
- 60 kg table load handles heavier fixtures and workpiece materials than the smaller MCD variants
- Glass scales and thermal compensation deliver consistent 0.5 µm accuracy across the full travel envelope
- Trunnion B/C configuration optimizes chip evacuation for deep-pocket precision finishing
Limitations
- 250 x 150 x 200 mm travel is still small by general machining standards, limiting applicability to precision components
- 5.5 kW spindle power still restricts roughing capacity—pre-roughed blanks are recommended for hard materials
- Price range of $480K-$650K is significant for a small-envelope machine, reflecting ultra-precision engineering
- HSK-E32 tooling is specialized and less widely available than HSK-A63 or CAT40
- Requires temperature-controlled environment for optimal accuracy performance

Frequently Asked Questions
01
A new Makino MCD2516-5XB typically runs between $480,000 and $650,000 depending on configuration. As the largest MCD variant, it carries a premium for the expanded travel and increased spindle power while maintaining sub-micron accuracy. Full configurations with advanced probing, automation interfaces, and enhanced thermal packages reach the upper range.
02
The MCD2516-5XB offers the most travel (250 x 150 x 200 mm vs 200 x 150 x 150 mm for the 2016 and 150 x 100 x 150 mm for the 1516). It also gets a more powerful 5.5 kW spindle (vs 3.7 kW), a 30-tool magazine (vs 20), and 60 kg table load (vs 40-50 kg). All models share the same 40,000 RPM spindle speed and 0.5 µm accuracy specification. Choose the 2516 when your precision parts exceed the travel limits of the smaller models.
03
For precision finishing of small-to-medium parts requiring sub-micron accuracy, yes. The MCD2516-5XB delivers finishing quality that exceeds what conventional VMCs can achieve, making it ideal as a dedicated finishing machine downstream of a roughing VMC. Many shops pair an MCD with a larger conventional machining center that handles roughing and semi-finishing of blanks.
04
Cycle times vary dramatically based on part geometry, material, and finish requirements. A small mold insert with complex 3D surfaces might take 2-8 hours of finishing on the MCD2516-5XB. The 40,000 RPM spindle enables productive feed rates even with fine step-overs (0.01-0.05 mm), and the 5-axis simultaneous capability maintains consistent surface quality without manual repositioning between operations.
05
Yes, the MCD2516-5XB can be integrated with pallet changers and robotic loading systems for automated operation. The 30-tool magazine supports extended unattended runs, and the Makino Pro 6 control includes automation management functions. However, given the precision nature of the work, automation is typically limited to pallet-based systems with precise fixturing to maintain the sub-micron accuracy the machine is capable of.
