Meta Description

Learn how to choose the right CNC turret lathe based on turning diameter, machining length, bar capacity, spindle, turret, and tailstock configuration. Explore the main features and applications of the TCK-50 CNC Turret Lathe.

How to Choose the Right TCK-50 CNC Turret Lathe

Choosing a CNC lathe requires more than checking the maximum turning diameter. Workpiece size, material, machining length, bar capacity, tooling, accuracy, and production volume should all be considered.

The TCK-50 CNC Turret Lathe is a slant bed CNC turning machine designed for shaft parts, disc components, sleeves, flanges, hydraulic fittings, and bar-stock products.

1. Confirm the Turning Diameter

The TCK-50 provides a maximum turning diameter of 360 mm and a standard turning diameter of 240 mm.

The maximum value represents the machine limit under suitable clamping and tooling conditions. For continuous production, the standard turning diameter is usually a more practical reference.

When the workpiece diameter is close to the machine limit, a larger machine may provide better tooling clearance, rigidity, and clamping flexibility.

2. Check the Machining Length

The maximum turning length is 500 mm, with a Z-axis travel of 550 mm.

When selecting the machine, consider not only the total workpiece length but also:

Chuck clamping length
Tool overhang
Tailstock position
Drill or boring bar length
Fixture thickness

For parts close to 500 mm, the complete drawing and clamping method should be reviewed before confirming the machine.

3. Evaluate the Bar Capacity

The TCK-50 has a 65 mm spindle bore and supports bar stock up to 50 mm in diameter.

It can be combined with an automatic bar feeder for continuous machining of:

Round bars
Steel tubes
Stainless steel bars
Aluminum bars
Hydraulic fittings
Small shaft components

When the bar diameter is close to 50 mm, material tolerance, straightness, and surface burrs should also be considered.

4. Select the Correct Spindle Performance

The spindle speed range is 50–4,000 rpm with stepless speed control.

This range is suitable for machining steel, stainless steel, cast iron, aluminum, brass, and other common materials.

Lower spindle speeds are suitable for larger workpieces and heavy cutting, while higher speeds are useful for smaller parts and finishing operations.

The actual cutting capacity also depends on material hardness, cutting depth, feed rate, tool type, and clamping rigidity.

5. Confirm the Turret Capacity

The TCK-50 is equipped with an eight-station horizontal turret.

A typical tool arrangement may include:

Rough turning tool
Finish turning tool
Grooving tool
Threading tool
Drill
Boring bar
Facing tool
Parting-off tool

The turret is suitable for external turning, internal turning, facing, drilling, boring, threading, grooving, and parting operations.

For milling, side drilling, off-center holes, or keyways, a machine with driven tools and C-axis capability should be considered.

6. Check the Tailstock Requirement

The machine is equipped with an MT5 tailstock for supporting longer shaft components.

The tailstock can reduce vibration and improve machining stability. It may also hold drills, reamers, or centers for axial machining.

For long and slender shafts, a steady rest or follower rest may also be required.

Typical Applications

The TCK-50 CNC Turret Lathe is suitable for machining:

Shafts
Sleeves
Bushings
Flanges
Disc parts
Hydraulic fittings
Valve components
Motor shafts
Automotive parts
Engineering machinery parts
Bar-stock components up to 50 mm

It is suitable for single-piece production, small batches, and automated mass production.

When to Choose the TCK-50

The TCK-50 is a suitable option when your project requires:

Turning diameter below 360 mm
Standard machining diameter around 240 mm
Turning length below 500 mm
Bar capacity below 50 mm
Eight-station turret
Hollow hydraulic chuck
Tailstock support
Multiple turning operations in one setup

Information Required for Machine Selection

For an accurate machine recommendation, customers should provide:

Part drawing
Workpiece material
Raw material size
Finished dimensions
Workpiece weight
Tolerance and surface finish
Production quantity
Required cycle time
Bar feeder or automation requirements
Local voltage and frequency

Conclusion

The TCK-50 CNC Turret Lathe combines a 360 mm maximum turning diameter, 500 mm turning length, 65 mm spindle bore, 50 mm bar capacity, eight-station turret, and tailstock.

It is a practical solution for machining shaft, sleeve, flange, disc, hydraulic, automotive, and bar-stock components.
