Cylinder Block Grinding Machine

SM1500

The SM1500 series surfacers are the most advanced surfacing machine available today.The SM1500 model is designed for surfacing from the smallest to large heavy duty diesel heads and blocks.
The SM1500 machines combine cutting edge control technology with proven traveling column machine tool dry surfacing technology to give the world’s most advanced surfacing machines available today.
Traveling column design proven for decades in engine block machining centers reduces floor space requirements and improves accuracy of surface finish.
The programmable down feed with multiple passes is ideal when large amounts of material need to be removed in one set up.Angle milling and weld removal are also easily done in one cycle.
Direct Drive Ball Screws and Linear Roller Bearing Slideways on vertical and horizontal movements combine to give precise motion control resulting in precision surface finish.
Full Steel Enclosure surrounds the machine and keeps the work area clean and free of chips and protects operators from moving machine parts.
Electrical Enclosure mounted on the side of the machine allows the back of the machine to be installed against a wall reducing floor space requirements.

Features

Latest Clear Path Integrated Servo Control Technology – State of the art electronic controls make the SM1500 machines the most advanced dry cutting surfacing machines available today.
Increased Vertical Travel – the traveling column is mounted on linear roller bearing slideways and has extended travel 510mm eliminating the need for parallels while being able to surface a wide variety of jobs from small single cylinder heads to tall diesel blocks.
Linear Roller Bearing Slideways – the vertical and horizontal movements are by precision direct drive ball screens and on linear roller bearing slideways.
Super Fine Surface Finish – Direct Drive precision ball screws and linear slideways combined with infinitely variable speeds and feeds allows surface finish as low as Ra3.2.Today’s MLS(Multi Layer Steel)head gaskets require super fine finish to seal combustion pressure and oil and water.
Touch Screen Control – Today, the SM1500 Series Surfacing Machines incorporate the latest Clear Path Integrated Servo Touch Screen Control Technology into a Dry Surfacing Machine capable of surfacing a wide variety of materials and with features such as multi pass automatic machining.TOWNHERO touch screen control technology make the machine easy and fast to learn and operate.Touch Screen Control shows the operator at all times by digital display theexact positon of the vertical and horizontal movements accurate to 0.01mm.
Dry Cutting – the spindle and cutter head system is specially designed and developed for dry cutting with CBN and PCD cutting tools eliminating the need for coolant.Of course,you can also choose the SMG1500 with grinding function and coolant.
Chip Collection System – the base casting and machine enclosure is designed to catch chips and direct them down into a roll out chip bin making clean up fast and easy.
Reduced Floor Space – Traveling Column Design and compact,one piece base castings give the most compact surfacing machines available today reducing floor space requirements.
Folding Doors – the stainless steel doors fold down with one hand for access to the work area and fold up to protect the operator and keep the work area clean of any chips.
Universal T Slot Base – Large One Piece Mechanical Cast Iron Base with T – Slots allows mounting of any fixture and any job – jacks and clamps can be placed anywhere!
Program Length of Part – Input length of surface to be machined and the machine travels the exact distance then returns to home – not necessary for time consuming setting of end stops.
Fast Floor to Floor Time – Heads can be surfaced in a few minutes and a pair of angled V8 heads in less than eight minutes.
Surface scanning by Laser sensor – The SM1500 machines is defined as the”Smart Rurfacer”,thanks to its laser sensor that scans the cylinder – head surfaces,thus recording their profile and automating milling operations.

Hinged Door

Drop down hinged door for easy one handed operation.

Linear Motion Construction

Linear Motion slide ways on the vertical and horizontal axis provide smooth and precise movement along with consistent surface finishes.

Touch Screen Control

Today, the SM1500 series surfacing machines incorporate the latest Clear path integrated Touch Screen Controllechnology into a dry surfacing machine capable of surfacing a wide range of materials and with features such as multi – pass automatic machining. Touch screen control technology makes the machine fast and easy to learn to operate. Touch screen control shows the operator at all times by digital display the exact position of the vertical and horizontal movements accurate to 0.01mm.

Advanced Axis Drive Motors

All axis feature a direct coupled digital servo controlled precision ground ball screw drive feed system for smooth and precise movement.

Electronic handwheel

The tool alignment speed is faster and more accurate when using electronic handwheel pair for milling and grinding,which greatly saves processing time.The external electronic handwheel is equipped with a long telescopic wire,which can be pulled to any position of the machine tool to operate,which is flexible and convenient to operate.
