Precision Engineered for Professional Machining

9" x 42" Table | 0.0002" TIR Spindle Runout | Variable Speed 60-4,500 RPM | Jig Bore Accuracy

When precision machining demands professional-grade accuracy and reliability, the Sharp Industries LMV-42 vertical knee mill delivers performance that sets new standards for its class. This isn't just another milling machine—it's precision engineering that transforms raw materials into components meeting the tightest tolerances your customers demand.

Jig Bore Accuracy in Production Environment

CNC ground quill with mirror finish and chrome plating achieves close to jig bore accuracy for quill downfeed operations. This precision construction, combined with maximum 0.0002" TIR spindle runout, enables machining tolerances typically requiring dedicated boring equipment.

ABEC-7 super precision spindle bearings ensure consistent accuracy throughout extended production runs while maintaining the surface finishes that precision work demands.

Professional-Grade Construction Features

Meehanite casting provides superior dimensional stability and vibration dampening compared to conventional gray iron construction. This premium material choice ensures long-term accuracy retention and smooth operation under demanding machining conditions.

Hard chromed ways deliver exceptional wear resistance for extended accuracy life, while tapered gibs allow precise adjustment to maintain tight tolerances as the machine ages.

Innovative Design Elements

Hand-scraped saddle bottom riding on knee ways provides superior oil retention and prevents dirt and chip contamination from compromising accuracy. This design reversal from conventional practice ensures consistent precision throughout the machine's operational life.

Dual clamps on knee and saddle lock components evenly to column and saddle, preventing skewing that compromises part accuracy. Adjustable handles accommodate 12 different positions for operator convenience.

Comprehensive Spindle Performance

Variable speed range from 60 to 4,500 RPM covers complete machining requirements from heavy roughing to precision finishing operations. R-8 spindle taper provides secure tooling retention with extensive compatibility across drilling, milling, and boring applications.

Self-lubricating motor shaft extends pulley life while dual cooling fans maintain optimal operating temperatures during extended production runs.

Substantial Working Envelope

9" x 42" table with generous travel ranges:

- X-axis (Longitudinal): 30" travel

- Y-axis (Cross): 12" travel  

- Z-axis (Vertical): 16" knee travel

- Quill travel: 5" with three automatic feed rates

- Ram travel: 12" for extended reach

Three T-slots at 2.5" centers with 5/8" width accommodate standard workholding while the substantial working envelope handles large components efficiently.

Advanced Head Positioning

360-degree head swivel with 45-degree tilt capability (left/right and up/down) enables compound angle machining without complex fixturing. This flexibility eliminates secondary operations while maintaining precision positioning throughout complex machining cycles.

Precision Feed Control

Three automatic quill feed rates (0.0015", 0.003", 0.006" per revolution) enable optimized drilling and boring operations while reducing operator fatigue. Unique double nut backlash eliminator ensures precise positioning in both directions.

Professional Maintenance Systems

One-shot lubrication system with backflow valve ensures consistent lubrication while preventing contamination. Front and rear way covers protect critical surfaces from chip damage while maintaining long-term accuracy.

Included backlash eliminator tool enables precise maintenance and adjustment procedures throughout the machine's operational life.

Extensive Expansion Capabilities

Comprehensive options include power feeds for all axes, digital readout systems, coolant systems, and specialized attachments. Auto lube pump, Kurt vises, right angle milling attachments, and complete clamping kits transform the basic machine into a complete machining center.
