Cutting zirconia through to titanium, the 52Max is Luhluh's floor-standing five-axis milling machine for dental laboratories. Capacity is a 27-station automatic tool changer. Blank formats are round discs and block materials, with automatic switching between wet and dry working. The spindle is rated at 2.5 kW, with no speed specified. The material list runs to zirconia, PMMA, wax, glass ceramic, titanium, cobalt chrome and composite, and the processing list to single crowns, bridges, veneers, inlays, abutments and screw-retained work. Throughput is not published, and neither are any dimensions, mass, electrical supply, air requirements, axis travel, or accuracy figures.

What a quotation buys here is a machine that cannot cut anything on its own. A wet-and-dry mill needs oil-free, dried compressed air at a stated pressure and flow, dust extraction for the dry side, and coolant supply and management for the wet. None of the three appears here, and none is stated as included. Two of the running costs are statutory rather than optional. Dry milling brings a duty under the Control of Substances Hazardous to Health Regulations, and any local exhaust ventilation fitted must be thoroughly examined and tested at least every fourteen months for the life of the machine.

Titanium and cobalt chrome both sit on the material list, and combustible metal dust can form an explosive atmosphere, which brings the Dangerous Substances and Explosive Atmospheres Regulations into the assessment. The sheet never says which materials run wet and which run dry. On a machine sold with automatic switching, that omission matters most.

No specification table accompanies this. Medigear.uk lists the 52Max for UK business buyers. Request the full specification, the conformity marking with its declaration, the air and extraction requirements, and the wet- and dry-material split from the seller before ordering.

The 52Max is for an operation that doesn't want to choose between a laboratory that takes prescriptions from several practices and a practice milling its own work chairside. A dry-only machine handles zirconia, PMMA and wax and stops there, and wet capability is what brings glass ceramic and metals into the same room. Anyone taking work across single units, bridges, veneers, inlays, abutments and screw-retained cases is quoting for all of those materials whether they can cut them or not, and the alternative to one machine doing both is sending part of the book out.

Blank format is the other half of the same argument. Discs suit batching, where a full tray of units is nested into one blank and run unattended. Blocks suit single cases turned round quickly, and the chairside-style work where one unit is needed now. A machine taking both lets the format follow the case rather than the equipment, which is what the sheet means by diversified production.

The constraint is what surrounds it. A floor-standing wet and dry machine needs a compressor, an extraction unit, coolant handling, and floor area for all of them, plus access for service. An operation already running dry milling has some of that. One moving from outsourcing to in-house has none of it, and the room has to be planned rather than found.

Buying runs through the usual routes. Private laboratories, dental groups, trust laboratories, teaching institutions, and practices milling chairside each apply their own procurement rules, and capital equipment like this clears health and safety and finance before anything else. The registration duty for custom-made devices works the same way in each of them. The manufacturer issues the conformity route documentation, and the seller provides it.

Wet and dry in one enclosure

Automatic switching between wet and dry working is the headline, and it is what puts zirconia, wax, glass ceramic and metals on the same machine. For an operation whose case mix shifts week to week, the practical benefit is taking whatever comes in without deciding which machine it goes to.

Discs and blocks from the same machine

Round discs suit nested batches run unattended overnight. Blocks suit single units wanted the same day. Accepting both means the blank format follows the case rather than the equipment, which is where the flexibility in this specification actually sits.

Twenty-seven tool stations

A large magazine makes unattended running possible, because a job needing roughing, finishing,g and detail tools per material cannot run overnight if someone has to change burs between stages. Twenty-seven stations hold several material strategies loaded at once.

A floor-standing format

Floor mounting takes the machine off a bench, which matters for a wet machine with a coolant tank underneath and for vibration isolation. It also means the footprint is the machine's own, and nothing else has to carry its mass.

A stated spindle power

Two and a half kilowatts is a real figure attached to the part that does the work. Power governs how much material you can remove before the spindle bogs down, and it separates a machine intended for metals from one intended for wax and polymers.

A mineral cast construction

The reference to integrated mineral manufacturing points to a mineral cast base. Mineral cast dampens vibration strongly, and on a machine cutting fine margins, that shows up directly in surface finish and tool life. Worth confirming, because it is a meaningful engineering choice rather than a marketing line.

One machine covers the published restoration list.

Single crowns, bridges, veneers, inlays, abutments, screw-retained work and crown and bridge are all named. An operation can read that list against its own order book and see immediately whether the machine covers what it actually quotes for.

The cost question is answerable in one email.

Air, extraction, coolant, tooling, blanks and the statutory examination interval are all knowable before an order is placed. None requires a trial or a site visit. What the supplier sends back, and how completely, is itself information about what kind of supplier they are.

Five-axis simultaneous machining

The machine is described as five-axis. No axis travel, rotation ranges, or simultaneous interpolation capability are published.

Automatic wet and dry switching

Switching between wet and dry working is described as automatic. No changeover time, coolant purge routine or drying cycle is published, and no statement is made about which materials use which mode.

2.5 kW spindle

Spindle power is published at 2.5 kW. No speed range, power curve, holder or collet type, runout figure, or replacement cost is provided.

27-station automatic tool changer

The magazine holds 27 tools. No shank diameter, tool length limit, detection method or changeover time is published.

Round discs and block materials

Both blank formats are supported. No disc diameter, disc thickness range, block dimensions, holder types or number of holders supplied is published.

Published material list

Zirconia, PMMA, wax, glass ceramic, titanium, cobalt chrome and composite materials are named. No hardness limits, recommended tool sets or material-specific cycle guidance is published.

Published restoration list

Single crowns, bridges, veneers, inlays, abutments, screw-retained work and crown and bridge are named. The list ends with an abbreviation indicating it is not exhaustive.

Integrated mineral manufacturing

Construction is described with this phrase, which in machine tool terms usually indicates a mineral cast base for vibration damping. The sheet does not explain it, and it provides no base material or damping ffigure

Floor model

The machine is floor-standing. No dimensions, mass, footprint, floor loading or levelling requirement is published.

Electrical supply not published.

No voltage, phase, frequency, current draw, or power consumption is provided for a machine carrying a 2.5 kW spindle.

Compressed air not publishe.d

No pressure, flow rate or air quality requirement appears, and the sheet does not say whether a compressor is included or separate.

Extraction and coolant not published

No extraction capacity or connection is described, and no coolant type, tank capacity, filtration arrangement or disposal guidance appears for the wet side. Neither is stated as included.

Accuracy not published

No positioning accuracy, repeatability, runout or test method is stated for a machine producing fitted restorations.

Control, software and conformity not publish.ed

No control system, software compatibility, file formats or connectivity is named, and no UKCA or CE marking, declaration of conformity, applied standard or guarding description appears anywhere.

The 52Max is described entirely in capabilities, not in specifications. It lists what it can cut, what it can make, and how many tools it holds. What it measures, weighs, draws and achieves are not. For capital equipment that reverses the usual order, the useful thing to do with this sheet is to turn it into a question set. Two of those questions are not optional. The conformity route is machinery rather than medical devices, which changes both the paperwork and the deadlines. The wet/dry split across a material list that includes titanium also determines what the dust assessment must cover. Medigear.uk lists the 52Max for UK business buyers and can arrange delivery, installation, commissioning, familiarisation and service cover. Request the full specification, the declaration of conformity, the air and extraction requirements, and the wet and dry split from the seller with the quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Three things, none of them on the sheet. Compressed air, because the spindle, the tool changer and the blank clamping on machines of this type all run on it, and the air has to be oil-free and dried, or it carries contamination straight into the spindle bearings and onto the work. Dust extraction, because the dry side produces respirable dust that has to be captured at source. Coolant supply, filtration and disposal for the wet side, because metal and glass ceramic swarf in coolant becomes a waste stream with its own handling. Ask whether any of the three is included, what the air pressure and flow requirement is, and what extraction capacity the machine expects.

Not stated, and it is the first question to ask. Zirconia, PMMA and wax are ordinarily dry processes; glass ceramic, titanium and cobalt chrome are ordinarily wet. A machine sold with automatic switching must handle both, but the buyer needs the split in writing because it determines the extraction duty, the coolant duty, and whether metal is ever cut dry. Request the wet and dry assignment for every material on the list, and ask explicitly whether titanium or cobalt chrome can be run dry under any circumstances.

Because combustible metal dust behaves differently from ceramic dust, finely divided titanium is a recognised ignition and explosion risk, and where a workplace can generate an explosive atmosphere, the Dangerous Substances and Explosive Atmospheres Regulations require the employer to assess it, eliminate or reduce the risk, and control ignition sources. That assessment covers the machine, the extraction unit and the collected dust together, not the machine alone. A wet process for metals removes most of the question. Get the manufacturer's written position on dry metal cutting before specifying anything.

A machinery mark, not a medical device one, and this is where specifications of this kind most often go wrong. A CNC machining centre placed on the Great Britain market is machinery, and conformity runs through the Supply of Machinery (Safety) Regulations 2008: a declaration of conformity, a technical file, compliance with the essential health and safety requirements, and instructions supplied in English. No MHRA registration, UK Responsible Person, or device classification applies to the machine itself. The sheet states that no marking is required. Ask for the declaration of conformity, which standards were applied, and the guarding and interlock arrangement.

Quite possibly, and for a different reason from the machine. Crowns, bridges and abutments made to a prescription for a named patient are custom-made devices, and the organisation that makes them is a manufacturer of custom-made devices with its own registration duty. That obligation attaches to the laboratory and its output, not to the milling machine, which is production equipment. It is worth separating the two clearly, because buying a mill doesn't create the duty, and not buying one doesn't remove it. A laboratory already producing restorations should already have this.

Unpublished, and power without speed says less than it appears. Spindle power indicates how much load the motor can handle before it stalls; spindle speed determines which tool diameters and feed rates are usable, and therefore what surface finish and cycle time the machine achieves. You need both figures to judge whether a given material and tool combination is workable. Ask for the speed range in rpm, the power curve if one exists, the tool holder or collet type, and whether the spindle is user-replaceable and at what cost.

Nothing published says. The station count is given, but no shank diameter, maximum tool length, tool detection method,d or holder type appears with it. Without the shank diameter, a laboratory cannot order burs, and without a maximum length, it cannot know which supplier's tools will clear. The changer count is the headline figure, but the tooling interface determines whether consumables can be bought competitively or only from the machine supplier. Ask for shank diameter, maximum and minimum tool length, and whether the tool magazine has breakage detection.

Not stated, which is fine on a machine making fitted restorations; that's a specification, not a detail. Marginal fit separates a usable crown from a remake, and it depends on machine accuracy, spindle runout, tool condition, and the material. Ask for positioning accuracy and repeatability with the test method named, spindle runout, and whether the figures are for a new machine or after a stated number of hours. Ask separately what calibration or verification routine the manufacturer expects and at what interval.

The phrase is unusual, and the sheet does not explain it. In machine tool construction, it normally refers to a mineral cast or polymer concrete base, chosen because mineral cast strongly damps vibration and improves surface finish and tool tilt. If that is what is meant here, it is a genuine engineering choice worth knowing about. Ask what the phrase refers to, what the base material is, and what vibration or thermal stability benefit is claimed for it.

Round discs and block materials, and no dimensions for either. A disc is described by diameter, thickness range and the step or shoulder that locates it in the holder, and a block by its dimensions and mandrel type. None of that is here. Ask for the disc diameter and thickness range, the block sizes and holder types supported, how many holders are supplied, and whether the machine accepts the blank formats the laboratory already stocks, because a mill that needs a different blank format changes the material bill as well as the machine bill.

Any laboratory expecting to switch it on from a single quotation, because the air, extraction and coolant are separate purchases and separate installations. Any buyer who cannot obtain the declaration of conformity, since machinery placed on the market without one should not be bought. Any operation intending to run metals and unable to get the wet/dry split in writing. And any laboratory whose CAM software has no post-processor for this control, because a mill that the existing software cannot drive is a very expensive paperweight. For a laboratory already running extraction and compressed air, with CAM that posts to it, the material range on offer here is genuinely broad.

Send it as one list. It covers the full specification with dimensions, mass, floor loading and footprint; the electrical supply with voltage, phase, frequency and current; the compressed air pressure, flow and quality requirement; the extraction capacity expected and whether a unit is included; coolant type, capacity, filtration and disposal; spindle speed range, holder type and replacement cost; tool shank diameter and length limits; axis travels and rotation ranges; positioning accuracy and repeatability with the test method; disc diameter and thickness and block formats; the control system and which CAM packages post to it; noise in decibels; the declaration of conformity with standards applied and the guarding arrangement; the wet and dry material split; and the warranty, service coverage and spares availability.
