Operation Manual for Turning Machine CK500

Introduction

Welcome to the CK500 CNC Lathe! This manual is designed to help operators quickly understand the machine’s basic functions, safety procedures, and maintenance requirements. Whether you're a beginner or an experienced machinist, follow this guide to ensure safe and efficient operation.

1. Safety Guidelines

⚠️ Critical – Ignoring safety rules may cause severe injury or machine damage!

1.1 Personal Protection

Wear PPE: Safety glasses, steel-toe shoes, and fitted clothing (avoid loose sleeves or jewelry).

No gloves when handling rotating parts (spindle, chuck).

1.2 Machine Safety

Pre-start check: Verify oil levels, air pressure, and ensure all bolts are tight.

Emergency stop: Locate the red E-STOP button—press immediately if something goes wrong.

Keep clear: Never touch the workpiece or tool during operation.

1.3 Workspace Safety

Keep the area clean—excessive chips can cause overheating or slipping hazards.

Ensure proper grounding to prevent electrical hazards.

2. Machine Overview

3. Operating Procedures

3.1 Power-Up & Setup

Turn on the machine:

Switch the main power, wait for the control system to boot (check for alarms).

Home the axes:

Select "REF" mode, press X+ then Z+ until the home lights turn on.

Mount the workpiece:

Clean the chuck jaws, secure the part evenly (avoid imbalance).

Install tools:

Load tools into the turret, set offsets using a tool presetter (e.g., T0101).

3.2 Loading a Program

Manual input: Type G-code commands (e.g., G01 X50 Z-20 F0.2).

USB transfer: Insert a USB drive, select "Program Edit" → "Load File".

3.3 Test Run

Dry run:

Use "Single Block" mode, run at low speed to check for collisions.

Tool setting:

Jog the tool close to the workpiece with the handwheel, set Z-zero (e.g., G50 Z0).

3.4 Production Run

Switch to "Auto" mode, press "Cycle Start". Monitor:

Chip color (silver = normal; blue = excessive heat).

Unusual vibrations? Pause immediately.

4. Troubleshooting

Problem Likely Cause Solution

Spindle won’t rotate Emergency stop engaged / Drive fault Reset E-STOP, restart control

Tool chipping Feed rate too high / Hard material Reduce feed (F-value), use tougher inserts

Dimensional errors Wrong offset / Backlash Re-measure tool offset, adjust parameters

5. Maintenance

5.1 Daily

Remove chips, wipe down guides and ball screws.

Check coolant concentration (5–10% emulsion recommended).

5.2 Weekly

Lubricate X/Z-axis rails with lithium grease.

Inspect hydraulic oil level (ISO VG32).

5.3 Long-Term Storage

Run the spindle for 10 mins weekly to prevent rust.

Cover the machine with a tarp to block dust/moisture.

6. Best Practices

Never edit programs or adjust fixtures while the machine is running.

Back up parameters regularly (battery failure can erase data).

Simulate complex programs offline before machining.
