NEW SMTCL CAK63 Series Flat Bed CNC Lathe

The SMTCL CAK63 Series is a practical and rigid flat bed CNC lathe platform designed for larger shafts, flanges, sleeves and general heavy workshop turning.

With a 630 mm maximum swing over the bed, 104 mm spindle bore and cutting-length configurations covering approximately 600 to 2850 mm, the CAK63 provides substantially greater workpiece capacity than the smaller CAK36, CAK40 and CAK50 platforms.

The Series is intended for workshops requiring reliable CNC turning without the additional cost or complexity of a full slant-bed turning centre.

Typical applications include:

• General engineering

• Mining maintenance

• Agricultural equipment repair

• Industrial maintenance

• Hydraulic components

• Shafts and sleeves

• Flanges

• Bearing components

• Small-to-medium batch production

• Heavy workshop turning


CAK63 Series Positioning

The CAK63 Series is best understood as a practical flat bed CNC lathe rather than a high-specification turning centre.

Its design priorities include:

• Rigid flat-bed construction

• Straightforward machine architecture

• Large spindle bore

• Broad workpiece-length capability

• Conventional tailstock support

• Practical four-position turret

• Manual or hydraulic workholding options

• Easy serviceability

• Controlled capital investment

The CAK63 is particularly suitable where conventional turning capability, workpiece size and machine simplicity are more important than high-speed automation.


Key Series Specifications

• Maximum swing over bed: 630 mm

• Maximum cutting-length range: approximately 600–2850 mm

• Spindle bore: 104 mm

• Main motor power: approximately 11 kW class, configuration dependent

• Recommended chuck size: approximately 315 mm class, configuration dependent

• Tool turret: Vertical 4-position turret

• CNC control: FANUC, Siemens or GSK depending on selected configuration

• Workholding: Manual or hydraulic options depending on final machine package

• Tailstock: Manual or hydraulic configuration depending on order

Final spindle speed, exact chuck size, bed length, workpiece length, machine weight, dimensions, rapid traverse and supplied equipment should be confirmed for the selected CAK63 configuration before quotation.


Rigid Flat-Bed Construction

The CAK63 uses a conventional horizontal flat-bed structure.

This machine concept is particularly suitable for:

• Larger shaft work

• Flange machining

• Sleeves and bushes

• Repair components

• Maintenance machining

• Low-to-medium production quantities

• Workpieces requiring tailstock support

Compared with a high-speed slant-bed turning centre, the CAK63 places greater emphasis on simplicity, rigidity and practical general-purpose use.


Large 630 mm Swing Capacity

The CAK63 provides a maximum swing over the bed of:

• 630 mm

This gives the machine substantially more diameter capacity than smaller CAK models.

The larger swing is useful for:

• Large flanges

• Brake and coupling components

• Large bearing housings

• Larger sleeves

• Hydraulic components

• General heavy workshop work

• Components with large raw-stock diameter


104 mm Spindle Bore

One of the key advantages of the CAK63 Series is its:

• 104 mm spindle bore

The larger spindle bore increases flexibility for:

• Large-diameter bar

• Tube

• Hollow shaft work

• Longer components passing through the spindle

• Heavy industrial components

This is a significant step up from the smaller CAK50 platform.


Broad Cutting-Length Range

The current CAK63 Series specification lists a cutting-length range of approximately:

• 600–2850 mm

This allows the machine to be selected around the actual workpiece requirement instead of purchasing unnecessary bed length.

Shorter configurations are more suitable where:

• Workshop footprint is limited

• Components are relatively short

• Large diameter is required but long shaft capacity is unnecessary

Longer configurations are more suitable for:

• Long shafts

• Hydraulic rods

• Sleeves

• Drive components

• Mining and industrial replacement parts

• Components requiring tailstock and steady-rest support


Select the Correct Bed Length

The correct CAK63 bed length should be selected according to:

• Finished component length

• Raw-stock length

• Chuck projection

• Tailstock clearance

• Tool clearance

• Steady-rest position

• Future workpiece requirements

Excess bed length increases:

• Machine footprint

• Installation space

• Capital cost

without necessarily improving machining capability for shorter workpieces.


Automatic-Shift Headstock

The existing CAK63 product information identifies an automatic-shift headstock design on the main models.

This provides a broad usable spindle-speed range for different machining conditions.

The headstock concept is intended to support:

• General steel turning

• Cast-iron machining

• Aluminium machining

• Large-diameter work

• Shaft turning

• Boring

• Threading

Final spindle-speed range should be confirmed against the selected machine and CNC package.


Vertical Four-Position Turret

The CAK63 uses a vertical four-position turret.

This simple and robust turret arrangement is suitable for general turning operations.

Typical tool positions may include:

• External turning tool

• Boring bar

• Grooving tool

• Threading tool

The four-position turret is particularly appropriate for jobbing and maintenance work where simple tooling arrangements are sufficient.


Main Motor

The current CAK63 Series specification lists:

• Main motor power: approximately 11 kW class

The exact spindle motor depends on final machine configuration.

Before quotation, motor specification should be confirmed against:

• Workpiece diameter

• Material

• Depth of cut

• Cutter or insert selection

• Required spindle speed

• Production duty


315 mm Class Chuck

The current CAK63 Series configuration guide identifies:

• Approximately 315 mm class chuck

as a typical machine configuration.

Depending on the application, manual or hydraulic chuck arrangements may be available.

Manual chuck is generally appropriate where:

• Production volume is low

• Workpiece variety is high

• Operator loading time is not critical


Hydraulic chuck is more appropriate where:

• Repetitive loading is common

• Cycle consistency is important

• Production quantity is higher


Final chuck diameter and compatibility should be confirmed before order.


Tailstock Support

The CAK63 can be configured with a conventional tailstock system.

Depending on final configuration:

• Manual tailstock

or

• Hydraulic tailstock

may be available.

Tailstock support is particularly useful for:

• Long shafts

• Slender components

• Hydraulic rods

• Drive shafts

• Components requiring centre support


Long slender components may also require a steady rest or follow rest.


Independent Oil Tank

The CAK63 product information identifies an independent oil-tank arrangement.

This design is intended to:

• Simplify maintenance

• Improve service access

• Separate lubrication-related systems from the main machine structure

• Support practical workshop operation
