VMC Q Series Vertical Machining Center – High Rigidity, High Precision

SMTCL VMC850Q-A General-Purpose Vertical Machining Centre

The SMTCL VMC850Q-A is a general-purpose vertical machining centre designed for productive machining of automotive, new energy vehicle and general engineering components.

Developed from SMTCL’s proven VMC850Q platform, the VMC850Q-A combines a practical 850-class machining envelope with high-speed axis movement, roller linear guideways and a flexible production-oriented machine configuration.

The machine is positioned in the mid-market and is designed to provide a strong balance of machining capability, productivity, reliability and overall investment value.

With 850 / 500 / 540 mm X/Y/Z travels, a 1000 × 500 mm worktable, BT40 spindle and 48 m/min rapid traverse, the VMC850Q-A is particularly suited to workshops machining medium-size housings, automotive components, electric-drive components, connecting rods and other production parts.

The machine also incorporates a rear chip-discharge layout and internal twin-screw chip evacuation arrangement, making it well suited to automated production cells and integration with gantry loaders or industrial robots.

General-Purpose VMC-Q Platform

The VMC-Q Series is SMTCL’s mainstream general-purpose vertical machining centre platform.

The Q Series is positioned in the mid-market and is designed around:

• High machining speed

• Strong overall value

• Reliable production performance

• Good machining capability

• High dynamic response

• Broad application flexibility

• Automation compatibility

The VMC850Q-A is particularly suited to production workshops that require a capable and productive machining centre without moving into the more specialised high-efficiency H Series or high-precision P Series.


Designed for Production Machining

The VMC850Q-A is designed for everyday production machining rather than simply occasional job-shop use.

The combination of:

• 10,000 rpm BT40 spindle

• 48 m/min rapid traverse

• Roller linear guideways

• 24-tool automatic tool changer

• Production-oriented chip management

provides a practical platform for efficient component manufacturing.

The machine supports:

• Milling

• Drilling

• Boring

• Tapping

• Pocket machining

• Contouring

• Multi-operation component machining

This allows many components to be completed in one setup, reducing handling and improving production consistency.


High-Speed Axis Movement

The VMC850Q-A provides rapid traverse speeds of up to 48 m/min on X, Y and Z.

High rapid traverse helps reduce non-cutting time, particularly on components containing:

• Multiple holes

• Multiple pockets

• Separated machining features

• Repeated drilling cycles

• Repeated tapping cycles

• Multiple tool changes

This improves overall cycle efficiency in batch-production environments.


Roller Linear Guideways

The VMC850Q-A uses roller linear guideways on all three linear axes.

The guideway arrangement provides:

• High load-carrying capacity

• Good structural rigidity

• High-speed movement capability

• Stable axis response

• Reduced friction

• Good positioning performance

• Suitability for production machining

The roller-guideway structure provides a useful balance between speed and rigidity for general engineering and automotive component production.


Precision Feed System

The VMC850Q-A uses precision ballscrew feed systems with Ø40 mm-class ballscrews on the X, Y and Z axes.

The feed system is designed to provide:

• Stable axis movement

• Good positioning response

• Low transmission backlash

• Consistent machining performance

• High-speed positioning

The combination of roller guideways, precision ballscrews and high-response servo drives supports both productive machining and stable surface quality.


10,000 rpm BT40 Spindle

The standard VMC850Q-A spindle provides:

• BT40 tool interface

• 10,000 rpm maximum spindle speed

• 7.5 / 11 kW motor power

• 35.8 / 70 Nm spindle torque

The spindle configuration provides a useful balance between spindle speed and machining capability.

It is suitable for:

• Aluminium

• Cast iron

• Carbon steel

• General engineering materials

• Automotive components

• New energy vehicle components

• Housings

• Plates

• General production work

The 10,000 rpm platform is particularly useful where cycle time, drilling, tapping and moderate-to-high-speed milling are important.


24-Tool Automatic Tool Changer

The VMC850Q-A is equipped with a 24-tool automatic tool changer.

This provides sufficient tool capacity for many production components requiring:

• Face milling

• End milling

• Drilling

• Tapping

• Boring

• Chamfering

• Finishing

A larger tool magazine reduces the need for manual tool intervention and helps support unattended or semi-automated production.


Production-Oriented Chip Management

One of the important characteristics of the VMC850Q-A is its production-oriented chip-management arrangement.

The machine uses:

• Rear chip-discharge layout

• Internal twin-screw chip evacuation

This configuration provides advantages for:

• Centralised chip collection

• Centralised coolant systems

• Automated production cells

• Gantry-loader integration

• Robot integration

• Multi-machine production lines

The rear-discharge design can simplify machine arrangement where several machines are installed together in an automated cell.


Automation Integration Capability

The VMC850Q-A is specifically designed with automation integration in mind.

It can be incorporated into production systems using:

• Gantry loaders

• Articulated industrial robots

• Automatic loading and unloading

• Centralised chip management

• Centralised coolant supply

• Multi-machine cells

• Flexible manufacturing systems

This makes the machine particularly suitable for automotive and new energy vehicle component manufacturers where production volume and repeatability are important.


Structural Optimisation

SMTCL’s VMC850 platform has undergone structural optimisation aimed at improving machining performance, reliability and precision stability.

Structural improvements include:

• Increased bed support points

• Increased bed section thickness

• Improved bed rigidity

• Increased chip-discharge height

• Increased effective coolant-tank capacity

• Increased column thickness

• Improved structural rigidity

• Improved assembly consistency

• Increased saddle thickness

• Improved saddle load capacity

• Improved axis-motion accuracy

These design changes are intended to improve both machine reliability and long-term precision stability.


Manufacturing Consistency

The VMC850 platform incorporates greater standardisation of components including:

• Guideways

• Ballscrews

• Servo motor mounting components

• Bearing housings

• Spindle components

• Tool magazine components

• Machine auxiliary components

Increased component standardisation helps improve:

• Assembly consistency

• Serviceability

• Spare-parts availability

• Production reliability

• Long-term maintenance support


High-Quality Machining Capability

The VMC850Q-A is designed to provide reliable surface machining performance through a combination of:

• Controlled machine assembly

• Precision component manufacturing

• Structured assembly-process control

• System performance tuning

• Rigid mechanical structure

• Stable feed-axis performance

The objective is to minimise visible tool-transition marks and provide stable surface quality during production machining.


Fine Feed Control

High-resolution servo control combined with the rigid machine structure provides stable fine-feed capability.

This supports:

• Smooth contouring

• Stable finishing

• Fine interpolation

• Controlled tool movement

• Consistent surface quality

This capability is useful for automotive components, mould components and precision production work where both dimensional accuracy and surface quality are important.

VMC850Q-A Compared with VMC850Q

The VMC850Q-A and current VMC850Q belong to the same general-purpose Q Series platform but should not be treated as identical machines.

VMC850Q-A

• X / Y / Z travel: 850 / 500 / 540 mm

• Worktable: 1000 × 500 mm

• Maximum table load: 500 kg

• Spindle: BT40

• Maximum spindle speed: 10,000 rpm

• Spindle power: 7.5 / 11 kW
