The Series is particularly suitable for workshops requiring reliable CNC turning of large and long components without the additional cost and complexity of a high-speed slant-bed turning centre.

Typical applications include:

• General engineering

• Mining maintenance

• Heavy industrial maintenance

• Hydraulic components

• Large shaft machining

• Heavy sleeves

• Large flanges

• Bearing-related components

• Agricultural and transport equipment repair

• Low-to-medium batch production

• Heavy workshop turning


CAK100 Series Positioning

The CAK100 Series is best understood as a large practical flat bed CNC lathe rather than a high-specification turning centre.

Its design priorities include:

• Large-diameter workpiece capability

• Long bed-length choices

• Rigid flat-bed construction

• Large spindle bore

• Heavy-duty turning capability

• Conventional tailstock support

• Manual or hydraulic workholding options

• Straightforward machine operation

• Practical maintenance

• Controlled capital investment

The CAK100 is particularly appropriate where workpiece size, shaft length and general heavy turning are more important than high-speed automated cycle performance.


Key Series Specifications

• Maximum swing over bed: 1000 mm

• Maximum cutting length range: approximately 1300–4800 mm

• Spindle bore: 104 mm on the main CAK100 models

• Main motor power: approximately 15 kW class, configuration dependent

• Recommended chuck size: approximately 500 mm class, configuration dependent

• Turret / tooling arrangement: Heavy-duty configuration, model dependent

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

• HNC alternatives may also be available depending on current factory configuration

• Workholding: Manual or hydraulic options depending on final package

• Tailstock: Manual or hydraulic configuration depending on selected machine

Final spindle speed, exact cutting length, chuck configuration, turret, tailstock, machine dimensions, machine weight and supplied equipment should be confirmed before quotation.


Rigid Flat-Bed Construction

The CAK100 uses a conventional horizontal flat-bed machine layout.

This machine concept is particularly suitable for:

• Large shafts

• Long shafts

• Heavy sleeves

• Large flanges

• Repair components

• Mining replacement parts

• Heavy maintenance machining

• General industrial turning

• Components requiring tailstock and steady-rest support

Compared with a production-oriented slant-bed turning centre, the CAK100 places greater emphasis on workpiece capacity, rigidity, simplicity and long-bed flexibility.


1000 mm Swing Over Bed

The CAK100 provides:

• 1000 mm maximum swing over bed

This allows the machine to accommodate substantially larger raw-stock diameters than the CAK80 Series.

Typical large-diameter work may include:

• Large flanges

• Heavy sleeves

• Couplings

• Bearing housings

• Large hydraulic components

• Large discs

• Industrial repair components

• Heavy fabricated or forged blanks


104 mm Spindle Bore

The current CAK100 Series specification lists:

• 104 mm spindle bore on the main models

This provides practical through-spindle capability for:

• Bar stock

• Tube

• Hollow shafts

• Long cylindrical components

• General industrial work

The workpiece diameter capability of the CAK100 comes primarily from its 1000 mm swing and large chuck capacity rather than an unusually large through-spindle bore.

Any larger-bore configuration should be confirmed separately and should not be assumed.


Long Cutting-Length Range

The current CAK100 Series specification lists an approximate cutting-length range of:

• 1300–4800 mm

This makes the machine suitable for:

• Medium-length heavy shafts

• Long drive shafts

• Hydraulic rods

• Long sleeves

• Industrial shafts

• Mining components

• Transport components

• Heavy repair work


Selecting the Correct Bed Length

The correct bed length should be selected according to the real workpiece requirement.

Consider:

• Finished component length

• Raw-stock length

• Chuck projection

• Tailstock position

• Tool clearance

• Steady-rest position

• Future workpiece range

The shortest bed that safely covers the actual workpiece is usually the most practical starting point.

Excessive bed length can increase:

• Machine footprint

• Installation requirements

• Workshop floor-space use

• Capital cost

without improving productivity on shorter components.


Automatic-Shift Headstock

The current CAK100 product information identifies an automatic-shift headstock design on the main models.

This provides a broad usable speed range for varied turning work.

The headstock arrangement is intended to support:

• Large-diameter turning

• Shaft machining

• Boring

• Threading

• General steel machining

• Cast-iron machining

• Heavy workshop cutting

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


15 kW Class Main Motor

The current CAK100 Series specification identifies:

• Approximately 15 kW class main motor

The exact motor specification depends on configuration.

Before quotation, the motor and spindle package should be checked against:

• Workpiece diameter

• Material

• Required depth of cut

• Tooling

• Spindle speed

• Production duty

• Roughing requirements


500 mm Class Chuck

The current CAK100 configuration guide identifies:

• Approximately 500 mm chuck class

This is appropriate for the larger workpiece diameter range of the CAK100 Series.

Manual or hydraulic workholding may be considered depending on the application.


Manual Chuck

Best suited where:

• Batch quantities are low

• Workpiece variety is high

• Large irregular components are common

• Manual setup flexibility is important


Hydraulic Chuck

Better suited where:

• Repetitive loading is common

• Production consistency is important

• Loading frequency is higher

• Reduced manual handling is beneficial

Final chuck size and hydraulic compatibility should be confirmed for the selected configuration.


Heavy-Duty Turret and Tooling

The CAK100 Series uses a heavy-duty turning-tool arrangement appropriate to the machine’s larger workpiece capacity.

Depending on final configuration, typical tooling may include:

• External turning tools

• Heavy boring bars

• Grooving tools

• Threading tools

• Drilling tools

• Facing tools

• Parting tools where appropriate

Final turret configuration and tool-section size should be confirmed at quotation stage.


Tailstock Support

The CAK100 can be configured with a conventional tailstock arrangement.

Depending on selected configuration:

• Manual tailstock

or

• Hydraulic tailstock

may be available.

Tailstock support is particularly important for:

• Long shafts

• Large shafts

• Hydraulic rods

• Drive components

• Components requiring centre support


Long and slender workpieces may also require:

• Steady rest

• Follow rest

• Suitable centres

• Controlled cutting parameters


Steady Rest and Follow Rest

Large and long workpieces often require additional support.

A steady rest can help:

• Reduce shaft deflection

• Reduce vibration

• Support heavy workpieces

• Improve machining stability

• Maintain dimensional consistency


A follow rest may be useful for certain long slender workpieces.

Support equipment should be selected from the actual component drawing.


Independent Oil Tank

The current CAK product information identifies an independent oil-tank arrangement.

This is intended to:

• Simplify maintenance

• Improve service access

• Separate lubrication-related systems from the main machine structure

• Support practical workshop operation


Coolant and Chip Management

The CAK platform uses a large waterproof groove and diversion-based enclosure arrangement.

This helps manage:

• Coolant

• Chips

• General workshop cleanliness

For higher chip-volume applications, a chip conveyor should be considered where compatible.


Typical Applications

The CAK100 Series is well suited to:

• General engineering

• Mining maintenance

• Heavy industrial maintenance

• Agricultural equipment repair

• Transport equipment repair

• Hydraulic repair

• Large shaft machining

• Sleeve machining

• Flange machining

• Large motor shafts

• Drive shafts

• Gear shafts

• Hydraulic rods

• Heavy sleeves

• Large bushes

• Large flanges

• Couplings

• Valve components

• Bearing housings

• Bearing rings

• Brake components

• Mining replacement parts

• Agricultural replacement parts

• Heavy industrial repair components


Material Capability

Depending on tooling, workholding and cutting conditions, the CAK100 can be used for common engineering materials including:

• Carbon steel

• Alloy steel

• Stainless steel

• Cast iron

• Aluminium

• Non-ferrous materials

Actual machining capability depends on:

• Material grade

• Workpiece diameter

• Workpiece length

• Depth of cut

• Tooling

• Workholding

• Tailstock / steady-rest support

• Spindle load

• Required tolerance

Key reasons to consider the CAK100 include:

• 1000 mm maximum swing over bed

• 104 mm spindle bore on the main models

• Cutting-length range approximately 1300–4800 mm

• Approximately 15 kW class main motor

• Approximately 500 mm chuck class

• Heavy-duty turret and tooling options

• Manual or hydraulic chuck configurations

• Manual or hydraulic tailstock options

• Long-bed configurations

• Suitable for large shafts and sleeves

• Suitable for large flanges

• Suitable for mining and industrial maintenance

• Practical for low-to-medium production volumes

• Straightforward machine architecture


CAK100 Compared with CAK80

• Maximum swing over bed: 800 mm

• Spindle bore: 104 mm

• Cutting-length range: approximately 1350–4850 mm

• Main motor: approximately 15 kW class

• Chuck: approximately 315–400 mm class

Best suited for:

• Large shafts

• Heavy sleeves

• Large flanges

• Long industrial components

• General heavy maintenance


CAK100

Current series specification:

• Maximum swing over bed: 1000 mm

• Spindle bore: 104 mm

• Cutting-length range: approximately 1300–4800 mm

• Main motor: approximately 15 kW class

• Chuck: approximately 500 mm class

Best suited for:

• Larger-diameter shafts

• Very large sleeves
