Machine Description

This manual describes 4 JURA machines: JURA Micromotor, JURA Graver, JURA Graver Plus and JURA Graver Pro.

Micromotor
The JURA Micromotor is an advanced tool designed for high torque and precise drilling operations. It combines a powerful brushless micromotor with the slim NSK E Type hand piece to be able to work with hard metals like platinum and titanium. The JURA Micromotor includes a bench top holder for the cable, preven.ng the cable pulling and ensures a more comfortable working experience. The motor is rated at 7.8 N cm, enabling consistent low-speed drilling at the desired speed.

JURA Graver
The JURA Graver is a pneumatic graver with build in air compressor that powers the hand piece during the engraving. The hand piece can be quickly modified by switching out the piston to allow for a wide variety of engraving styles. The piece can be controlled through either the foot pedal or a rota.ng dial on the cabinet.

JURA Graver Plus
The JURA Graver Plus comes with both the brushless micromotor from the JURA Micromotor as well as the hand piece from the JURA Graver.

JURA Graver Pro
The JURA Graver Pro further expands on the JURA Graver Plus by adding both a cold air blower and a hot air blower. The cold air blower can be used to clean the work piece from dust while the hot air blower can be used for hea.ng and souring the Shellac kit and/ or Thermo-Lock®. A separate small compressor is with a minimum of 5 Bar air pressure is required to use both the cold and hot air blowers.

04| Although this equipment does not generate dust itself, the tools used in the hand pieces may do so. When sharpening tools, the user should take appropriate steps to avoid dust inhalation. Certain tool materials generate harmful dust while being ground or sharpened. Dust from Grinding/ Shaping Diamond/ Ceramic polishing Wheels and Inserts of any kind while opera.ng the machine will produce dust of potentially hazardous ingredients. The dust this product can cause nose, throat, skin and eye irritation and temporary or permanent respiratory disease in a small percentage of exposed individuals, possibly leading to disability or death.

Transport and Storage

During transportation and storage make sure to stay within the following characteristics:

• Temperature: 10 – 40 °C
• Atmospheric Pressure: 700 hPa to 1060 hPa
• Humidity : 30 – 75%

Humid air enters electric equipment, damaging wires and other components. Long-term condition with humidity about 65% will cause damage to the Machines. The device will struggle to function due to rus.ng and corrosion. Water droplets cause short circuits when they come in contact with the devices. In addition, when the machine overheats, it might break down.

Installation

Power off the machines and air supply when doing any connections, to prevent possible malfunctions.
Connect the machine: Insert the power cord into the receptacle on the back of the machine. Connectors vary per country. Always use the power cord with a properly grounded power outlet, using proper adapters as needed. Using it with an ungrounded system could expose the equipment to electrical damage.

Operating Instructions

Once all the previously mentioned steps are followed correctly the machine can be operated.

Power on: Put the speed control dial or the control box at ‘O’ Check the well-locked collet chuck turning the hand piece handle or pulling out the bur. Hold the hand piece by one hand and turn on the control box power by the other hand. You will hear a beep-sound, it lights green on the power switch and shows the numbers on the rpm display box.
Power off: The green light on the power switch and the lights of the bacons are gone off. The number of the rpm display box is disappeared.
Clock: Set the .me on the digital display, the hour with the leer boron and minute with the right boron. Hour display is shown from 01 to 24.
Display: The digital readout that shows rpm speed by the 1000 rpm. It also has a digital display for elapsed .me that is used in factory production work or whenever you need to know how much .me was involved in a particular task. Foot/Hand: Select whether controlling by hand or foot on the Hand/Foot Select boron as pushing each .me it changes by hand and foot. Depending on your selection, the speed will increase by stepping on the pedal or adjusting the speed with the volume boron on the control box.
Direction: Choose the rotation direction by right/leer select boron as pushing each .me, it switches between right and leer.
Speed: Although the brushless motor and the control box will allow speeds up to 50,000 rpm, the hand piece is rated for 20,000 rpm maximum. Caution must be taken to not exceed the maximum rpm for the hand piece. Put the volume dial at ’0’ and then press the hand/foot boron and motor boron at the same time. The speed can be changed within a range of speed pre-sets by the volume dial of the control box. The speed will increase by pushing on the pedal. When using for the first time, start at a low speed, and gradually increase to a high speed. Operate the speed control dial control box surly.

JURA recommends speeds for various applications as following:

• Cylinders & Tapered burs: 5000 – 6000 rpm
• Drills & Ball burs: 3000 – 4000 rpm
• Polishing: approximately 18,000 rpm

Memory: The Seung of direction and hand/foot selection are being memorized on turning off the machine. Therefore, be aware when turning the power back on.

MICROMOTOR HAND PIECES

JURA Tools offers the EQ.14.01 The JURA Slim Nose Pave Hand piece for Micro pave diamond Seung. The JURA Slim Nose Pave Hand piece Is the lightest and the shortest handpiece that reduced strengthening of your hand while making long hours doing the finest pave work. With max. 35.000 rpm, this hand piece is designed for delicate pave work with
recommended ball bur size up to 2mm. Jura recommends:
For Drill Bits & Ball Burs 3-4000rpm.
For Cylinders & Tapered Burs 5-6000rpm.
For Fine Polishing a. 15000rpm (Use only with well centered, high quality steel mandrills!)
For Seung Large stones and using ball burs from up 2mm, we recommend the EQ.14.02 JURA High Torque Handpiece.
By reducing the speed, this hand piece enables you max control and power while working with larger burs.
For polishing, we recommend the EQ.14.03 Heavy duty hand piece (included with the Micromotor).
To mount the bur, insert it into the chuck and turn the Bur Lock Ring in the direction of the mark [C] until it clicks and the Black Dots align (see Figure 4.3). To remove the bur, turn the Bur Lock Ring in the direction of mark [O] until it clicks.
Figure 4.3: Micromotor bur moun.ng instructions

Make sure that the position is always in the locked position when you start working. Pressing the pedal of the micromotor, without any drill/bur fixed in the hand piece chuck, will damage the hand piece bearings or cause possible injury. Please ensure, the hand piece chuck is completely locked when placing the drill/bur.
Do not drop the hand piece as it may get damaged or break. This might cause vibration of the bur, overhea.ng or damaged bearings. Replace the hand piece for a new in such case. Always use the Micromotor Top Bench holder to prevent the hand piece from falling or cable damage.
Hand piece might get stuck on the micromotor due to constant vibration. Disconnect the micromotor hand piece once a month from the motor and put it back on to prevent it from geeing fixed too tight. The hand piece disconnects from the micromotor by a quick pull. They do not screw together, they are a friction fit. Never connect or disconnect the hand piece until the motor has completely stopped.
Drills & Burs: The JURA Tools® Micromotor hand piece is suitable for drills, burs or mandrills with a diameter of Ø 2,36mm. We strongly recommend to use high quality drills, burs or mandrills for your micromotor. Cheap versions are not properly centered and will also cause damage to the bearings of your micromotor hand piece. The drill or bur might get stuck in the chuck if being used over a very long .me or high force. We recommend to take out the drill or bur regular and fix it back into the chuck. Use lubricant for extending life/endurance of your drill and burs.
The Micromotor can overload due;

• Using burs larger than Ø 2mm over a long period of .me.

• Not using prober lubricant for drills/burs

• Using wrong ally of drills/burs for the type of metal that needs to be worked on.

• Using cheap drill/ burs or mandrels.

ENGRAVING HAND PIECE

The “Power” boron on the control box regulates the stoke power of the engraving hand piece. The “Speed” boron is responsible for Seung a maximum speed depending on your work. Turn the power boron all the way to the leer for the finest Seung and power up slowly until the preferred power is reached. The rage is three complete turns. By pressing the pedal, the hand piece will start exhilara.ng strokes per minute from 0-up. Finding the right sarongs is very personal. Find the right power and speed for the chosen piston and spring for your particular kind of work. Many variations are possible!
Always use the Universal Hand piece holder to prevent the hand piece from falling or cable damage. Be careful not to drop the hand piece as it may get damaged or break.
Handpiece operation: Unlike traditional or push engraving where a firm grip and manual forward force is required, the JURA pneumatic hand piece requires only a light grip and guidance. Relax, allowing the engraving system to move the tool forward and through the material with guidance. Most graver slips are due to manual hand pushing and an overly firm grip on the hand piece. Holding the hand piece with the graver is similar to holding a dinner knife. For stippling,
hammering, or similar techniques, position the hand piece similar to holding a pencil.
Maintenance: Depending on the intensity of your work, once in a while the hand-piece must be cleaned with alcohol. Open the hand piece and clean the ways, piston and spring with a cogon stick and alcohol. Make sure all parts are dry before Phuong the parts together again. Do NOT use any lubricants inside of the hand piece!
Pistons & Springs: The set includes a 4 and 6 grams piston. 2x Ø8mm Spring 0,5 & 0,4mm wire, 35mm long. The 4 grams piston offers you the option to tune the power for finer engraving work. Meanwhile the 6 grams piston will allow you to do deeper cuing, working on harder metals and perform hammering. The spring regulate the force. Harder spring will naturally slow down the stroke. Simply replace the piston and or spring and reassemble. The piston has a round end. The round end MUST face the nose or it will NOT work properly.
Do not oil/lubricate inside of the hand piece and prevent greasy hands while changing the spring and/ or the piston!
Quick changes: The JURA Engraving Hand piece comes with a set of 10pcs of Quick changes. The Quick changes are designed for the most efficient working method. The included colour coding allows you to recognize your gravers by type. The Quick change organizer will allow you to keep them organized and easy to search for the graver you need while holding the organizer underneath the microscope. Insert the graver into the .p of the quick change and fix it with the supplied 1,5mm hex key to stay in place. Additional Quick changes are sold per set op 10pcs on www.juratools.com/shop.

A set of several O-rings are included for the hand piece and the quick changes for maintenance purpose.

Carbide gravers: The engraving hand piece is suitable for JURA original quick changes only and gravers with a diameter of Ø2,36mm. A properly sharpened graver or similar tool is required to cut through the surface of metal and other materials. The quality of the cut will depend on how well the gravers are sharpened, how well the machine is programmed, as well as the surface used to engrave on. Sharpening gravers is a very delicate job that requires professional skills and experience!
Set of Pre-sharpened Carbide gravers contains; Flat, 30º, 45º, 60º, 75º, 90º and 120º. The final shape of your graver depends completely on the type of your work. Shaping of the gravers must be done with Diamond Wheels offered on www.juratools.com/shop.
The JURA Carbide Gravers are made from a special grade of carbide for impact usage. This carbide will cut materials of greater hardness and toughness than hardened steel gravers and is also suitable for use on sorer materials. Even impact-resistant grades of carbide are subject to point failure and must be sharpened in a manner that produces a durable point.

It is recommended to use a set of diamond polishing wheels for shaping, polishing and gung of the gravers.

• SG.DP.YW: Yellow / Fine
• SG.DP.BE: Blue / Medium
• SG.DP.BK: Black / Rough
• SG.DP.CW: Cuing Wheel
  These polishing wheels can be purchased at www.juratool.com/shop
  

Grinding of any inserts will produce dust of potentially hazardous ingredients. Dust from grinding this product can cause nose, throat, skin and eye irritation and temporary or permanent respiratory disease in a small percentage of exposed individuals. Permanent respiratory disease can lead to disability or death. Coolant mist from wet grinding may contain dust.
