Key Features & Advantages

30°/45° Slant-Bed Architecture — Chip-Free, Operator-Friendly

The SZGH-TK50 bed tilts at 30° or 45° from vertical. Gravity pulls chips and coolant directly down and away from the cutting zone and the guide rails — not across the work surface as on a flat-bed lathe. The practical result:

• Fewer chip-recutting events that would otherwise score the workpiece surface or accelerate tool wear

• Cleaner coolant return — chips drain into the chip conveyor without operator intervention

• Better operator sightline — the inclined spindle centerline brings the cutting zone into direct view from standing height, reducing fatigue on long production shifts

The same geometry that helps chips fall free also improves rigidity: the slant-bed cross-section is deeper in the load-bearing direction than a flat-bed of equivalent width, giving the SZGH-TK50 superior vibration damping per kilogram of casting.

Resin-Sand Cast, High-Rigidity Frame — Precision That Holds Over Time

The bed and frame are cast as a single integrated structure using a resin-sand wood-mold process. Resin-sand casting produces a denser, more homogeneous grain structure than green-sand alternatives, which translates to:

• Higher damping capacity — vibration from interrupted cuts (keyways, cross holes) dissipates through the casting rather than feeding back into the spindle

• Tighter dimensional stability over thermal cycles — the mass and section consistency of the resin-sand frame resists thermal bowing that would shift the spindle centerline relative to the turret

The frame and bed are cast together (not bolted), eliminating joint compliance — a common source of low-frequency chatter in assembled-frame lathes.

High-Precision Telescopic Sleeve Spindle (A2-6) — Bore Parts Without Regrinding

The SZGH-TK50 spindle is a high-speed, high-precision telescopic sleeve unit with the spindle pulley machined as part of the same assembly. This integrated machining approach ensures the pulley is concentric to the spindle bore to within the spindle's own tolerance — any out-of-round in the pulley would add directly to spindle runout, so SZGHTECH machines both in a single setup. All spindle assemblies are dynamically balanced before installation.

The A2-6 spindle nose is the international standard for lathes in the Ø300–600 mm swing class. 8-inch chucks from Kitagawa, SMW, or domestic suppliers mount directly without adapters. The 66 mm spindle bore passes Ø50 mm bar stock — enabling bar-feed operation for shafts, pins, and bushings without facing and parting as separate operations.

8-Station Servo Turret — Minimize Tool Change Time, Maximize Spindle-On Time

The 8-station turret holds turning, boring, threading, grooving, and parting tools simultaneously. A typical part program for a stepped shaft with internal bore, external thread, and face groove can run to completion without any mid-cycle tool change by the operator. Turret index time is measured in fractions of a second — the machine is cutting again before the coolant from the previous tool has finished draining.

Eight stations are the practical optimum for a 500 mm swing lathe:

• More than enough for complete shaft and disc programs (typically 4–6 tools)

• Leaves spare stations for redundant tools or backup holders — reduce changeover time when one insert wears mid-shift

• Fewer mechanical components than a 12-station turret → lower maintenance frequency and faster index verification

Fast-Response Servo Feed System — 18 m/min Rapid, Both Axes

Both X (cross) and Z (longitudinal) axes drive through precision-ground ball screws coupled directly to servo motors. Backlash is effectively zero in the loaded direction. Rapid traverse at 18 m/min on both axes means:

• Air-cutting time between features is minimized — the spindle reaches the next cutting position in milliseconds, not seconds

• The same high-stiffness ball-screw-plus-linear-guide combination provides positioning accuracy during threading cycles where the Z axis must follow the spindle rotation precisely

The linear slide rail on the bed body paired with the slider block on the saddle eliminates stick-slip that would cause micro-positioning errors during fine finishing passes.

Automatic Intermittent Lubrication — Precision Preserved, Maintenance Reduced

Every lubrication point — guide rails, ball screw nuts, spindle bearings — receives oil on a 15-minute/8-second automatic cycle. The positive-displacement pump ensures each point receives a fixed oil volume regardless of back-pressure. Operators do not need to remember to lubricate at shift change; the machine lubricates itself. The interval and duration are adjustable to suit the ambient temperature and production intensity of the specific workshop.

This matters for buyers planning multi-shift operation: a machine that misses one lubrication cycle on a guide rail will show premature wear within months. The SZGH-TK50 automatic system removes human error from the equation.

Applications & Industries

The SZGH-TK50 excels in high-efficiency, high-volume rotating-body part production — the combination of 8-station turret, 3,500 rpm spindle, and 18 m/min rapids minimizes cycle time on parts that would otherwise require multiple setups on a manual lathe or a larger machine.

SZGH-TK50 vs. SZGH-46Z vs. SZGH-6150 — Choosing the Right Lathe

The SZGH-TK50 is the volume-production choice: optimized for cycle time, not envelope. If your parts have milled flats, cross-holes, or radial features, consider the 46Z turning-milling platform. If your parts exceed 500 mm in length or 500 mm in diameter, the 6150 is the correct path.

Frequently Asked Questions

Q1: What is the difference between the SZGH-TK50 and a flat-bed CNC lathe at the same price point?

The SZGH-TK50 slant bed (30°/45°) offers three structural advantages over a flat-bed lathe: (1) chip evacuation by gravity keeps the cutting zone clear without operator intervention; (2) the inclined cross-section provides higher rigidity per kg of casting; (3) the operator sightline to the cutting zone is direct from standing position. Flat-bed lathes of comparable swing typically carry lower purchase prices but require more frequent chip cleaning stoppages, especially in high-volume production.

Q2: Can the SZGH-TK50 run bar stock automatically with a bar feeder?

Yes. The A2-6 spindle nose with a 66 mm bore and 50 mm bar capacity is compatible with standard short-bar and long-bar feeders from LNS, SMW Autoblok, and domestic suppliers. Bar-feed operation eliminates manual loading between parts, enabling one operator to supervise multiple machines — the same efficiency model used across the SZGH compact milling lineup.

Q3: What threading capability does the SZGH-TK50 have?

The SZGH controller supports G32/G92/G76 threading cycles (or equivalent) for straight threads (UN, Metric, BSP), tapered threads (NPT, BSPT), and multi-start threads. The servo Z axis follows spindle encoder feedback for thread pitch accuracy. Maximum thread pitch is limited by the maximum cutting feed rate of 18 m/min × spindle TPI — at 3,500 rpm, fine threads (0.5–2 mm pitch) run at full production speed.

Q4: How does the 8-station turret compare to a 12-station turret for my application?

For disc and shaft parts with up to 6 different cutting operations (face turn, OD rough, OD finish, bore, thread, groove), 8 stations are sufficient with 2 spare positions for backup inserts. A 12-station turret adds cost and index time without adding capability for most turning programs. If your parts require live tooling (milling slots or cross-holes), the SZGH-TK50 does not support live turret — consider the 46Z or 46J turning-milling platforms.

Q5: What is the difference between the 30° and 45° slant-bed configurations?

The 30° slant is more common on medium-duty lathes: it provides good chip clearance and a stable gravity load path for heavy chucks and workpieces. The 45° slant improves chip fall angle further and reduces the machine's floor footprint depth — at the cost of slightly higher tipping moment on the turret during heavy radial cuts. For most disc and shaft work in the SZGH-TK50's capacity range, either angle performs equivalently. Your SZGHTECH sales engineer can confirm which is standard for your order.

Q6: What controller does the SZGH-TK50 use, and can I specify Fanuc or Siemens?

The standard controller is SZGH (SZGHTECH's own CNC), which is G-code compatible and operates on a Fanuc-style syntax that most trained CNC operators recognize. Fanuc 0i-TF, Siemens 828D, and Mitsubishi M80 configurations are available on request. Contact export02@szghtech.com with your controller preference when requesting a quotation.

Q7: Is the SZGH-TK50 suitable for stainless steel turning?

Yes. The 11 kW spindle, rigid slant-bed frame, and precision-ground ball screws provide the combination of cutting power and structural stiffness needed for stainless steel (304, 316, 17-4 PH). Key requirements for stainless: use sharp-edged coated carbide inserts, maintain chip-breaking geometry to avoid long stringy chips that would otherwise wrap around the chuck, and run continuous coolant. The SZGH-TK50's auto-lubrication and coolant system support sustained stainless cutting cycles.

Q8: What is the lead time, warranty, and after-sales support?

Lead time is 20–35 working days from deposit confirmation. Warranty covers 12 months on all mechanical and electrical components (consumables — inserts, chuck jaws, coolant, lubricant — excluded). Remote support is available 24/5 via WhatsApp. SZGHTECH has local service representatives in the USA, Turkey, Romania, Russia, Egypt, Thailand, and Mexico.
