Introduction

Tired of long workpiece vibration, misalignment issues, or tailstocks that lack durability? As a professional machine tool accessory manufacturer, Shenzhen Metalcnc Tech presents our high-performance Lathe Tailstock Assembly – engineered for both CNC and conventional lathes to deliver stable workpiece support, pinpoint accuracy, and long-lasting reliability. Below is a concise guide to help you choose, use, and maintain the tailstock effectively.

How to Choose the Right Lathe Tailstock

Match Lathe & Workpiece Specs: Compatible with lathes with bed width 200-400mm and spindle center height 80-150mm (custom solutions for non-standard models available). Opt for the heavy-duty model (reinforced cast-iron housing, 150kg load capacity) for workpieces >500mm or >50kg; standard model suffices for lightweight parts (≤20kg).

Prioritize Precision Features: Our tailstock features ≤0.002mm runout for concentricity, precision-ground Acme thread lead screws (0.01mm micro-adjustment), and 500-800N clamping force – ensuring stable positioning without damaging the lathe bed.

Align with Machining Needs: Standard model (MT3/MT4 Morse taper center) for basic support; multifunctional model (removable center + drill chuck adapter, MT2-MT5 compatible) for drilling/reaming/tapping. Housing: HT200 cast iron (heat-treated); spindle: 45# steel (quenched and tempered) – avoid deformable aluminum housings.

Factory Direct Advantage: Competitive pricing with no middlemen. Every unit undergoes 3-stage quality inspections (concentricity, load, wear resistance) – request test reports for verification.

Quick Operation Guide

Installation & Alignment: Slide the tailstock onto the lathe bed, align with spindle center (deviation ≤0.003mm via dial indicator), and lock the bed clamp evenly. Use live centers for rotating workpieces, dead centers for stationary tasks; keep Morse taper clean and lubricated.

Workpiece Setup: Position the center 10-15mm from the workpiece end for thermal expansion. Use brass-tipped centers for soft materials (aluminum/copper) and carbide-tipped for hardened steel. Add a steady rest for workpieces >1m to prevent vibration.

Multifunctional Use: For drilling/reaming/tapping – remove the center, insert MT3/MT4 drill chuck adapter, secure the tool, and feed slowly (1-2mm/rev for steel, 3-5mm/rev for aluminum). Clean the adapter after use.

⚠️ Safety & Maintenance Tips

Critical Safety Rules

Do not exceed load capacity (standard: 50kg; heavy-duty: 150kg).

Wear safety goggles and gloves when adjusting the tailstock.

Confirm the tailstock is locked and debris-free before starting the lathe.

Maintenance Schedule

Frequency Tasks

Daily Wipe lead screw, taper, and clamp; remove chips/debris.

Weekly Lubricate with ISO VG32 machine oil; retighten loose bolts.

Monthly Inspect center wear (replace if runout >0.005mm); clean taper.

Quarterly Test clamping mechanism; adjust tension bolt if loose.

Common Troubleshooting

Drift: Tighten lead screw lock nut or replace worn screws (genuine spare parts available).

Concentricity issues: Clean taper/center; check lathe bed alignment.

Hard adjustment: Apply more lubricant – do not force the handwheel.
